WARNINGDANGER FROM HOT SURFACES

Steam boilers have high temperature surfaces, that if touched may cause serious burns. Only competent and qualified personnel should work on or in the locality of a steam boiler and ancillary equipment. Always ensure the working area and

floor are clear of potential hazards, work slowly and methodically.

Do NOT store inflammable materials near the boiler.

WARNINGDANGER FROM INCOMPLETE COMBUSTION

The importance of correct burner adjustment to achieve lowemissions, safe, clean and efficient combustion is paramount.Poor combustion, where unburnt gas forms carbon monoxide is both a health hazard, and the potential risk to the boiler

from overheating, caused by re-burning of the unburnt gas in the secondary flue passes.

WARNINGThe importance of correct boiler water and feedwater cannot be over emphasised, see the relevant section in this manual.

CAUTIONLOW FEEDWATER TEMPERATURE

Low feedwater temperature can result in thermal shock to the boiler pressure vessel. Return the maximum amount of

condensate and if necessary preheat the feedwater. If in doubt consult Fulton Ltd.

CAUTIONWATER SOFTENER and CHEMICAL TREATMENT

The chemicals required to operate the water softeners andchemical treatment plants CAN BE SUPPLIED by

Fulton Ltd.It is the responsibility of the operator to ensure adequate

supplies of chemical are available at all times (including commissioning).

Costly repairs could be required should the plant operate without chemicals or the wrong dosage of chemicals.

CAUTIONHYDRAULIC TEST - RISK OF BRITTLE FRACTURE

Hydraulic testing requires specialist equipment and is normally only required by engineering surveyors / inspectors.In order to ensure the material/ pressure vessel does not suffer from brittle fracture, hydraulic testing should not be

carried out below 7°C.

WARNINGPrior to the commencement of any work requiring the

removal of cover plates and the opening of control panel box, the electrical supply to the boiler must be isolated.

SECTION 2 - INSTALLATION

2.1 GENERAL

2.2 SITING

2.3 VENTILATION

The installation of a J Series Dual Fuel Fired Steam Boiler should be carried out by competent personnel in accordance with all relevant safety regulations. It is the responsibility of the installer to ensure that these regulations are complied with.

The requirements and instructions contained in this section are for boilers being installed to operate on Natural Gas or 35 sec. Fuel Oil.

The flooring must be level, laid in a non-combustible material and be of sufficient strength to support the boiler.

(Reference should be made to Utilisation Procedures as stated in IGE/UP/10 Part 1 Communication 1676, and in particular to Section 5, Location of Appliances).

The boiler house should be sufficiently sized to allow easy and safe access to all parts of the boiler for operational and maintenance purposes.

Reference should be made to Section 5 - General Data to ascertain the relevant dimensions and weights, special note should be taken of the required vertical clearance required for maintenance.

WARNINGMaintenance on the burner assembly requires the area directly aboveand to one side of the boiler must not be obstructed with pipework or

equipment which would interfere with the removal of the complete burnerunit. Care should be taken on installation of the boiler to ensure this

area remains clear of obstructions.

!

Adequate fresh, clean air is necessary for safe and efficient combustion, and should be provided at high and low level in accordance with BS 6644 1991 and IGE/UP/10 Part 1 Communication 1676.

Note:a) Ensure that there is adequate ventilation in the boiler room. Lack of ventilation will create a high

temperature and cause control lockout. There is a minimum ventilation requirement to supply the air for combustion.

b) Do not keep exhaust fans running with windows, doors and vents closed, this will interfere with the necessary boiler draught.

c) Do not store chemicals such as perclorethylene in the boiler house, the fumes may damage the boiler and flue and cause the burner to lock out on flame failure.

Note: see Section 5 for low and high level values.

The boiler is supplied with a stainless steel flue spigot that should be inserted into the flue outlet in the back of the boiler and secured with the three angle clips supplied loose in the trim box. The height and type of flue will generally be subject to local planning regulations and approvals. The following information is intended to provide assistance where the installation of a simple flue is required.

Where multi-boiler flues or difficulties are experienced, specialist advice should be obtained. The flue diameter must be the same or larger than the flue flange provided with the boiler and the outlet should be at least 1 meter higher than the nearest ridge to avoid down draughts. Where a chimney cowl is fitted, care should be taken to ensure that the distance between the lowest point of the cowl and the top of the flue is 1.5 x the diameter of the flue, and that it is of the terminal cone type.

FIG. 4 BOILER FLUE CONNECTION

2.4 FLUE OUTLET

Note:a) If the flue layout is such that it may produce an excessive up-draught, a draught stabiliser may be required.b) Avoid fitting 90° elbows whenever possible, if unavoidable compensate by increasing the flue diameter.c) Ensure all flue pipes from the boiler to the main flue have a rising pitch.

Feedwater stop valve

Check valve

Feedwater Dip Pipe

Feedwater line

The quality of the water used in the boiler will affect the life and performance of the boiler. Feedwater contains solids and dissolved gases, these may promote encrustations of scale; foaming, priming, surging; corrosion and pitting; or caustic embrittlement. To prevent this happening it is strongly recommended that a reputable water treatment concern is consulted prior to commissioning the boiler.

Note: see Section 5.3 - Recommended Water Conditions.

Connect the feedwater pump discharge to the check valve inlet with 25mm. bore pipe (this may be reduced to 15 mm, where the discharge pipe work is shorter than 4m in total. The pump suction pipe work must remain at 25mm minimum diameter and be as short as possible). Install the stop valve supplied between the boiler and the check valve. The check valve must be positioned so that it is below the internal water level of the boiler, and should be installed at least 1m after the feedwater pump. The reason for this placement position is that the check valve is designed to have water on both sides to enable it to function correctly.

It is essential to protect the feedwater pump from damage by foreign matter, a strainer should therefore be fitted in the pump suction pipework.

Care should be taken to ensure the pipe work is properly aligned and not placing any strain upon the feedwater pump.

Note: The boiler feedwater pump may contain an inhibitor and this should be flushed from the pump prior to fit-ting the pump to the boiler. Failure to do so may result in water bounce or foaming due to the inhibitor forming a seal in the boiler. If the boiler is to be operated with little or no condensate return, consideration should be given to pre-heating the feedwater. If in doubt consult Fulton Ltd. The feedwater inlet connection on some boilers is located on the left hand side of the boiler below the sight glass assembly.

FIG. 6A BOILER BLOWDOWN (models 6 - 15) FIG. 6 BOILER BLOWDOWN (models 20-60)

2.6 BLOWDOWN VALVE

There are four blowdown valves on the boiler, the boiler blowdown valve at the rear of the boiler, the water column blowdown valve and each of the water level gauge (sight glass) blowdown valves.

All of these valves must be connected to a blowdown receptacle of approved design. Regulations exist covering such items and care must be taken to ensure compliance with these regulations.

If in doubt regarding blowdown arrangements, consult Fulton Ltd.

Note: 20J - 60J main blowdown connection is integral, via a boiler mounted flange.Where possible the main blowdown pipework on 20 - 60J boilers should drop down to a union connection to allow removal of the inspection flange without the necessity to remove the blowdown pipework.

WARNING Factory fitted safety valves are preset to protect the boiler only and must not be used to protect any

other items not capable of accepting boiler pressure.

An individual wiring diagram for the boiler is located on the inside cover of the control box. When referring to the electrical specification of the boiler, the reference number located on the rear inside wall of the control box and the wiring diagram number should be quoted. The audible alarms provided are mounted on the side of the control panel, if not audible they should be repositioned where they can be heard by a person competent to take the appropriate action should the alarm be activated. Unless otherwise specified, the alarms supplied will be mains voltage models. Unless otherwise specified all models are supplied with burner motors and feed water pump motors arranged for operation on a three phase supply. The power ratings and requirements are given in Section 5.2 - Boiler Specifications.

2.7 MAIN STEAM VALVE

2.8 STEAM SAFETY VALVES

The main steam stop valve should be inserted in the steam line approximately 305mm from the top of the boiler.

2.9 WATER GUAGE SET

(The design may vary from that illustrated) Numbers may vary due to individual country’s regulations.)Boilers are normally supplied with two complete water level gauge sets. The water level gauge blowdown cock should be connected to the auxiliary blowdown line from the water column blowdown valve in 3/8 in. soft copper tubing.

2.10 ELECTRICAL REQUIREMENTS

Safety valves are factory fitted and preset, they MUST NOT be adjusted. The discharge outlet should be piped to a safe discharge point and the piping so arranged that any condensate trapped in the pipework will drain away from the valve.

Note: It is recommended that the safety valve discharge pipework is installed to the requirements of BS806 clause 4.9.7. / BSEN 134801-1:2002

a) The lift pressure is indicated on the safety valve. (Do not adjust).b) The safety valve fitted to the boiler is designed to prevent the boiler exceeding its design pressure.c) Any system connected to the boiler not capable of accepting boiler pressure must be protected

by a separate safety valve set to the required pressure.

FIG. 9 GAS SUPPLY

2.11 GAS SUPPLY

Verify that the burner is suitable for the type of gas being supplied. Ensure that the piping from the meter is the correct size, and that a gas cock is inserted in the line between the boiler and the meter. To avoid pressure drops, eliminate all unnecessary bends and elbows in the pipework between the gas meter and the boiler. A scale trap is provided on the gas train and should be used.Burners suitable for operation on natural and manufactured gas are supplied with gas trains or a modular gas head. A minimum pressure of 18 mbar at the specified flow rate, is required at the gas train for natural gas installations and a minimum pressure of 50 mbar is required at the gas train for manufactured/L.P gas installations.If the gas supply is in excess of 100 mbar for natural gas a suitable regulator is required before the main gas valve.Burners arranged for operation on L.P. gas are supplied with gas trains. It is essential that the MAXIMUM pressure of the gas at the gas train does not exceed 80 mbar and does not fall below 50 mbar. A suitable regulator is required before the main gas valve.To obtain these pressures, a pressure regulating device or service governor must be fitted to the supply line from the storage tank to the boiler gas train.Careful consideration must be given to the siting of LPG storage tanks to prevent over pressure conditions arising, due to temperature rises caused by solar gain.

The positioning of the oil storage tank will be dependent on site conditions and local regulations. The burner fuel pump is of the bypass type requiring the installation of feed and return lines between the oil storage tank and the boiler. These lines should be in tubing of a minimum bore of 10 mm. A fire valve, stop valve and check valves should be inserted in the oil feed line. To avoid blockages in the fuel pump and burner nozzle, a metal cartridge oil filter should be fitted. Fibrous cartridge filters are not recommended. The final connections between the fuel pump and the feed and return lines should be made with the flexible fuel lines supplied. If the oil storage tank is positioned higher than the boiler, a non-return valve should be fitted to the return line. To overcome suction problems at the fuel pump, all vertical lifts in the feed pipe should be made as close to the boiler as possible. The burner fuel pump pressure is preset at the factory and should not require adjustment.

2.14 COMMISSIONING THE BOILER

Dual fuel boilers that use a common burner assembly and have a switch change over from one fuel to another, have to be commissioned on the basis of a primary fuel (usually gas), with the secondary fuel as a back-up. The primary fuel should be commissioned as 2.16 oil firing or 2.17 gas firing.The secondary fuel then has to be commissioned using the air settings for the primary fuel. In practice this means adjusting the fuel input of the secondary fuel to achieve acceptable combustion.As more air is required for oil combustion the consequences are that when oil is the secondary fuel there will be a small reduction in the fuel input rate.

It is essential that the commissioning procedures listed below are carried out by a Fulton Service Engineer who will have the necessary experience and testing equipment to ensure that the installation is not only correct, but is operating safely and at optimum efficiency.

Flue CommissioningPrior to initial firing of the boiler, the flue must be checked for leaks.This is done by BOTH of the following methods:

a. Visual InspectionCheck joints between all flue sections for quality of seals. Where the flue passes through the structure of the building use your judgement as to the integrity of this section of the flue.

b. Smoke TestWith the flue capped, the drain stabiliser pipe (if fitted) blanked and a smoke generator inserted into the flue, there should be no smoke visible from the flue.If either of these tests fail or at any time during boiler operation, there is doubt about the integrity of the flue, shut down the boiler and contact Fulton Ltd immediately.

Note: Flues that are designed to operate with positive pressure should be tested to the latest regulations.

2.14.1 BOILER INSPECTION AND INITIAL FIRING OIL

1. Ensure the boiler has been washed out after installation. It is advisble to conduct a water analysis before operating the boiler. Examine the probes in the water column and the boiler shell. Replace any damaged probes.

2. Remove the burner and check that the electrodes have not been damaged. If the burner is fitted with a flame detector, remove the detector and check for damage.

3. Check that the burner is the correct type for use in a dual fuel boiler. Replace the burner and reconnect the copper oil lines to the oil nozzle assembly and gas connection, ensure these connections are tight. Reconnect the ignition leads and replace the flame detector.

4. Ensure that the gas supply isolation valve is closed.

5. Check the rotation of the oil pump motor. Ensure that the oil supply flow and return valves are open. Bleed the oil pump.

6. Ensure that all wiring connections are correct and that all terminal screws are tight.

7. A barometric type draught stabiliser, if fitted in the flue, should be set for a draught of - 0.01 in. to 0.02in. (0.025 mb to 0.05 mb) of water column pressure with the burner off.

8. Check that the visual flame signal display on the burner controller (5 LED bar) is fully illuminated during pilot and main flame.

9. Open all the valves in the feedwater line. Switch on the feedwater pump motor and fill the boiler, see Section 3 - Operation. The operation of the pump controls should be checked by using the boiler blowdown valve (located at the rear of the boiler). When the water level sight gauge is reading half full, the pump will stop. Open the boiler blowdown valve and slowly drain the boiler. When the water level falls below the PUMP ON probe, the pump should start. If the pump does not start, check the probe connections. Close the boiler blowdown valve.

10. Start the burner as detailed in Section 3 - Operation. Allow time for the fuel pump to prime itself.

11. After the burner has been firing for approximately five minutes, adjust the main air control gate to obtain a clean combustion.

SECTION 3 - OPERATION

The following instructions are given for the guidance of the operator in the use of the J Series Dual Fuel boiler and to provide adequate information to ensure that when the boiler is put into use it will be done safely and without risk to health. Where original equipment Service Manuals are supplied, they must be read and understood in conjunction with this manual. All warnings and cautions must be observed.

DRYING OUT TIME

The refractory casing of the boiler is made from a material that uses a high proportion of water in the mixing process. Whilst some of the water is driven off by chemical reaction and the initial test firing, the refractory is still ‘wet’ when the boiler is delivered. For a few days after the boiler is commissioned and in service, water will be seen running from the bottom of the casing and from around some branch pipes.This is perfectly normal and part of the drying process.

3.1 GENERAL

3.2 BOILER CONTROLS

The following brief description of the controls used on the J Series Dual Fuel boiler is intended to provide the operator with a basic understanding of the operating principles, which is essential for the continued efficient operation of the boiler.

Note: All the controls are of the ‘fail-safe’ type and are wired in series; failure of any one will automatically shut down the boiler.

Low Water Relays and Feed Water Pump Relays. These relays operate in conjunction with probes suspended in the boiler and water column to automatically maintain the level of water in the boiler and to cut off the burner should the water level fall to an unsafe level.

Steam Pressure Control(s). Located on the control panel box and connected to the steam pressure gauge assembly by copper tube, the pressure regulator controls the On/Off cycle of the burner, shutting the burner off when maximum pressure is reached and switching it on when the steam pressure falls.

Note: A set-back pressure controller is fitted when multi-boilers are fitted with a sequence control.

Burner Programmer. This is the main control in the panel box. The programmer in conjunction with a sensing device ‘supervises’ the ignition sequence, proves the flame is satisfactory and finally ‘monitors’ the established flame. Should any fault occur, either during the ignition sequence or during normal running, the programmer will immediately go to ‘lockout’ and the Multibloc gas valve will be closed.

Air Pressure Switch. Mounted on the burner scroll, this switch is operated by the pressure of air entering the burner through the throat of the scroll. Lack of air, or insufficient pressure, will prevent the switch completing the circuit thus preventing the burner from operating.

Fuel Pump. Mounted on the burner scroll and driven by the burner motor, the fuel pump delivers oil to the burner nozzels at the correct pressure to allow complete atomisation and therefore combustion.

3.2 BOILER CONTROLS - CONTINUED

Note: Boilers fitted on skid units and in plant rooms are interlocked with the feedwater and condensate return tank, after switching the boiler on at the boiler control box isolator switch, the reset button on the tank control box must be reset. This reset must also be selected after any electrical outage.

Gas Head Assembly Consists of a multiblock located in the main gas line, incorporating an integral governor, pressure switch and gas valves. The independent pilot line having a manual gas cock, a governor and two electrically powered gas valves. The pilot governor maintain a constant pressure of gas during the ignition sequence. The electrically powered gas valves are controlled by the burner programmer.

Indicator lights are fitted to the control panel as an additional aid to the operator. The meaning and operating sequence of these lights is as follows:

Start / Low Water Reset This switch is used to start the boiler and to reset the low water alarm. When the switch is pressed to initiate the start-up sequence, the low water alarm lamp also illuminates and the low water audible alarm sounds. Keeping the switch depressed for approximately 2 seconds cancels the low water alarm and initiates the burner start sequence. Illumination of this switch and sounding of the audible alarm at any other time other than at switch on indicates that the boiler has gone to a lockout (safe condition) due to low water. Once the water in the boiler has been restored to a safe operating level, pressing the switch will reset the controls.

Circuit On Indicates that power is being supplied to the control panel.

Low Water Alarm (1st. low water).This light will energise, when the boiler is switched on and the water level is between 1st. low water and 2nd. low water. A light will illuminate and a pulsing alarm sound. Low Water Reset (2nd low water). The 1st. low water light and alarm are replaced by the 2nd. low water light and a continuous alarm, indicated by the low water reset switch. The second alarm must be reset, the first alarm will be automatically reset by the return to normal water level.

Ignition This lamp indicates the ignition transformer has been energised, it will remain illuminated for 5 - 10 seconds approximately during the ignition sequence.

Burner On This lamp indicates that the burner is running and that the flame is being monitored by the burner programmer.

Flame Failure Alarm (reset) This switch will illuminate if the burner goes to a lockout condition due to flame failure. Pressing the switch will reset the burner controller.

Oil Valve The two lamps provide a visual indication that the magnetic oil valves have been energised. Low Flame / Start and Main FlameModels 40J and 60J are fitted with the following indicator lamps in place of the two oil valve indicator lamps: The burners on models 40J and 60J are fitted with a two-stage combustion system. The low flame start lamp indicates that the first stage of combustion is in progress and that the burner should be firing. Once the second stage of combustion is reached (full firing position), the low flame start lamp extinguishes and the main flame lamp illuminates.

This lamp will remain illuminated until the burner is shut down.

3.3 INDICATOR LIGHTS

! WARNINGNo more than two attempts should be made to start the boiler by resetting the

flame failure alarm (reset) Further attempts could cause the boiler and fluesystem to fill with vaporised oil which could cause an explosion.

Inspect the steam and feedwater pipework, valves and fittings for signs of leakage. If leaks are suspected, shut the system down and evacuate the system to atmospheric pressure before attempting any repairs.

Note: Ensure that the water level is maintained during the pressure build up. If any part of the equipment is not operating correctly, the fault should be investigated before the boiler is used. Ensure that all blowdown pipework is safe and discharged to a blowdown receptacle.

Fulton Ltd recommends that these tests and checks are carried out on a regular basis to ensure that the boiler is operating safely.

Tests should be carried out by a competent person trained to perform such tests. If any test shows that the equipment is not operating correctly, the fault should be investigated and corrected before the boiler is used.

Any rectification or repairs should be carried out by trained, competent service personnel.

4.1 VISUAL CHECKS

4.2 WATER LEVEL AND LOW WATER SAFETY CONTROLS

The following procedures ensure the correct functioning of the water level controls and the low water safety controls.

a) If the boiler is not firing and not under steam pressure, lower the water level using the main blowdown valve:

If the pump is running:

1. Observe the water level in the water level gauge (sight glass).

2. Verify that the pump continues to run until the Pump Off level is reached and then switches off.

If the pump is not running:

1. Check that the water level in the water level gauge is between Pump On and Pump Off levels.

2. Lower the water level by opening the main boiler blowdown valve.

3. Verify that the pump starts to run when the water level reaches the Pump On level.

4. Close the main boiler blowdown valve.

1. No Power Check fuse or circuit breaker. Reset or replace as necessary.

2. Pressure Control Disconnect all power to the controller. Disconnect the wires from the controller. connect an ohmmeter between the switch terminals. Lower the set point of the controller, the switch should make. raise the set point and re-check, switch should break. if the controller operates improperly, replace it.

Burner Cut-off 1. Oil tank empty Refill the oil tank. A slight delay in the re-priming of the fuel pump may cause the burner programmer to require resetting before the boiler operates satisfactorily.

2. Power Supply Check fuse or Circuit breaker. Reset or replace as required.

3. Ignition Electrodes Check electrodes for carbon build-up, clean if required. Check settings adjust if required. Check for cracks in porcelain, if found, replace.

4. UV Detector Check for dirt on detector, clean as required. Check for proper location of detector.

5. Faulty Air Switch Check for faulty air switch by jumpering the two air switch leads at the terminal block. If the boiler starts and runs with the jumper in place, the air switch should be replaced.

6. Faulty Level Control Check the level control relays are securely mounted on their bases. Check the power supply to each. The relays may be checked by swopping positions and checking they are both functioning.

7. Oil Nozzle Check for clogged nozzle, clean or replace.

8. Transformer Check voltage between transformer neutral at terminal block to be sure transformer is being powered.

9. Burner Control Check voltage between pilot terminal and neutral and ignition terminal and neutral. Check must be made before the control locks out on safety. If no power replace control.

10. Pressure Control Disconnect all power to the controller. Disconnect the wires from the controller. Connect an ohmmeter between the switch terminals. Lower the set point of the controller, the switch should make raise the set point and re-check, switch should break. If the controller operates improperly, replace it.

Note: One of the most common causes of flame failure is dirt/sediment in the oil filter, oil lines, solenoid valves or nozzle, caused by a new delivery of oil. If the oil tank level is allowed to fall near to the bottom of the tank it is highly probable that sediment on the bottom of the tank will be disturbed and mixed in with the new oil delivery, especially if the delivery rate is too fast.

5.3 RECOMMENDED WATER CONDITIONS

IMPORTANT

It is very important that a strict water management program is followed to ensure trouble free boiler operation.

The following are recommended for feedwater and for boiler water

mg/kg = Milligrams per KilogramCaCO3= Calcium CarbonatePO4 = PhosphateSiO2 = Silicon Dioxide

1 Grain hardness = 17.118 ppmtherefore 70 ppm = 4.10 grains hardness.

For practical purposes mg/kg = ppm

It is critical that the boiler water pH be alkaline in the range 10.5 -12.0 Daily boiler blowdown is essential to help prevent formation of deposits and reduce Total Dissolved Solids (TDS).

Consult your Water Treatment specialist to establish the frequency and duration of blowdown required to achieve the required conditions.

FIG. 36 WATER LEVEL PROBE COMPONENTS

The “Terminal & Securing Nuts” are tightened to a specified torque during manufacture which causes the “PTFE Insulation” to seal against the probe body. Therefore these nuts must not be adjusted because the seal will be broken which may cause the probe to leak. (See FIG. 36)

“Angle Rajah” ONLY must be used to connect wire to the probes because they clip directly to the “Terminal Nut”. Spade Connectors must NOT be used because the “Terminal Nut” would require adjustment and therefore cause the probe to leak. (See FIG. 37)

N.B. The “Probe Rod Grub Screw and Lock Nut” are suitably tightened during manufacture, meaning the probe is ready to be installed without any adjustment.

The ONLY instance a spanner should be used, is to turn the “Probe Body” in order to remove or reinstall the entire probe.

! IMPORTANTu Terminal & Securing Nuts must not be adjusted.

u Only Angle Rajah are to be used to connect wire to the probes.

The Fulton motorised high/low control is designed to improve the efficiency of the boiler by switching the firing rate from high fire (when there is low steam pressure in the boiler) to low fire (when the boiler reaches a high steam pressure). The systems major components comprises of; two stage gas valves, motorised air damper unit and two stage steam pressure switches.

Air Damper Motor

High/Low Fire Cams

Air Damper Housing

With the steam pressure switch preset to the high and low fire operational requirements of the system, and the boiler operating normally, steam pressure will gradually increase until the high pressure limit is reached, the pressure switch will then switch the two stage gas valve and the air damper motor to the low fire position.

The boiler will continue to operate at low fire until the steam pressure falls to the low pressure limit setting on the pressure switch. At this point, the gas valve and the air damper will switch the boiler into high fire mode and the sequence of high fire / low fire is regulated automatically with no routine maintenance required.

Note: Should the boiler attain the off setting of the on/off control pressure switch, the burner will switch off on low fire and then restart in the normal way on high fire.

APPENDIX B MOTORISED HIGH / LOW CONTROL

! CAUTIONThe adjustment of the air gate control motor or the two stagegas valve should only be carried out by qualified personnel,incorrect adjustment could result in damage to the pressurevessel and/or the production of harmful combustion gases.

1. Set the cams on the air damper motor to the initial position. Start the boiler and wait until the motor and gas valve have driven to high fire. Adjust the main (primary) air gate to achieve the best combustion with the least buffeting in the furnace.

2. Using the low fire hold switch, hold the boiler in low fire. The air damper motor should move to its low fire position and the high fire light on the control panel should extinguish, indicating the gas and air input rates have been reduced to approximately half the high fire input rate.

Note: If gas flow rate equipment is available, the low fire gas input rate should be adjusted to the correct value (see fuel input rates table) by rotating the black 1st stage partial adjustment ring located below the 2nd stage solenoid.

3. The ideal low fire CO2 constituent of the flue gases is 8 - 10.5%. Place an exhaust gas analyser into the flue, reduce or increase the amount of air entering the boiler as required, by adjusting the low fire cam (N2) position.

Note: The reaction of the motor to a change in cam positions is:

Reduced air: adjust the cam to reduce the amount of air entering the boiler, the reaction of the motor will be immediate.

Increased air: adjust the cam to increase the amount of air entering the boiler, switch the low fire hold switch off. When the motor has driven back to high fire turn the low fire hold switch on, the damper will drive back to its new low fire position. Adjust the cams until the correct CO2 figure is achieved.

Note: Any adjustment to the cam positions requires an adjustment to its interlock cam position.

4. Switch off the low fire hold switch.

Note: if gas flow rate equipment is available, the high fire gas input rate can now be set (see fuel input rates table) by adjusting the pressure control screw located under a protective cover on the black electrical connection block.

5. The high fire CO2 constituent of the flue gases is 10 - 10.5%. Place an exhaust gas analyses into the flue, reduce or increase the amount of air entering the boiler as required, by adjusting the high fire cam (N1) position. To reduce the amount of high fire air, the damper will have to be driven to its low fire position and back again, before it takes up its new position. Ensure that the high fire interlock cam N5 is always set approximately 5° below the high fire motor position cam N1. Record all cam settings and the high and low fire final gas elbow pressures for future reference.

6. Adjust the pressure switch (PS2) to the high/low switch over point.

The daily testing of boiler water level controls is a mandatory requirement as defined in the Health & Safety Executive Guidance Note BG01, Arrangements 2 and 3.The level of supervision is dependent upon the type of level controls (limiters) fitted.Boilers fitted with self monitoring high integrity controls (limiters) should be tested daily by a qualified boiler attendant, but may be supervised during the silent hours and weekends by a competent person trained to respond to an alarm.

Daily testing of the controls is required which can be by simulation, with a weekly test by interrupting the feedwater pump and lowering the water by evaporation.

1.1 DAILY TESTS

With the burner firing:

1. Press and hold the 1st Low Water test button 5 - 6 seconds, the Low Water alarm sounds, and the Low Water indicator lamp illuminates, and the burner shuts down.

2. Release the test button.

3. After approximately 17 seconds the Low Water alarm will cancel, the Low Water lamp will extinguish, and the burner will restart

1.1.1 1ST LOW WATER DAILY

1.1.2 2ND LOW WATER DAILY

With the burner firing:

1. Press and hold the 2nd Low Water test button for 5 - 6 seconds, the Low Water alarm sounds, and the 2nd Low Water Reset switch illuminates, and the burner shuts down.

2. Release the test button.

3. After approximately 17 seconds the 2nd Low Water Relay will reset.

4. To cancel the 2nd Low Water level alarm and light, depress the 2nd Low Water Reset switch.

The burner will restart.

Pump Interrupt Switch

FIG. 40 CONTROL PANEL SIDE

Note: These tests can be carried out consecutively, however it is possible that if the boiler is under load conditions the 2nd Low Water alarm will occur immediately after the burner has shut down on 1st Low Water, without the apparent loss of any more water. The reason is the collapse of the steam bubbles at the water level surface when the heat is removed. The degree of collapse could be such that the water level will disappear from the bottom of the sight glass before the alarm sounds. Should this happen, the 2nd Low Water Level alarm should be checked by lowering the water level slowly by partially opening the main blowdown valve.

With the burner firing:

1. Switch the Pump Interrupt switch to the Pump Interrupt position.

2. By evaporation lower the water level in the boiler until the 1st Low Water alarm sounds and the Low Water indicator lamp illuminates, and the burner shuts down.

3. Switch the Pump Interrupt switch to the Pump On position.

4. The pump will start and restore the water level to the normal position and switch off.

5. After approximately 17 seconds from restoring the 1st Low Water level the Low Water alarm will cancel, the Low Water lamp will extinguish, and the burner will restart.

1.2 WEEKLY TESTS (IN ADDITION)

1.2.1 1ST LOW WATER WEEKLY (IN ADDITION)

1.1.2 2ND LOW WATER WEEKLY (IN ADDITION)

With the burner firing:

1. Switch the Pump Interrupt switch to the Pump Interrupt position

2. By evaporation lower the water level in the boiler until the Low Water alarm sounds, the 2nd Low Water Reset switch illuminates, and the burner shuts down.

3. Switch the Pump Interrupt switch to the Pump On position.

4. The pump will start and restore the water level to the normal position and switch off.

5. After approximately 17 seconds from restoring the 2nd Low Water level the 2nd Low Water Relay can be reset.

6. To cancel the 2nd Low Water Level alarm and light, depress the 2nd Low Water Reset switch.

7. The burner will restart.
