With power to the boiler. Are there indicator lights on or any error messages? If the indicator lights are on which ones? Check with boiler manual to understand what lights or error message mean and correct if


3 Gas

Is the gas isolation valve on? At the boiler, at the meter. Do other gas appliances work?

Check the gas isolation valve is on at the boiler and at the meter. If OFF do not turn on unless safe to do so. Check why it was turned OFF. Do the other gas appliances work?


4 Room Thermostat.

Is the display very dim or not showing at all? Is the room thermostat calling for heat? Turn it off, turn on, does it click and show the correct symbol?

If nothing happens – the batteries may need replacing, the room thermostat may be faulty. Bridging out the switch can be used to test this. Check voltage before re-moving cover.


5 Boiler.

Does the boiler start to work and then shut down? Fan, Pump, Ignition. Is there an usual noise coming from the boiler? Is there water running from the pressure relief valve?

Try turning knob on the pressure relief valve and releasing it. If it is still faulty turn OFF IMMEDIATELY and call Hunt Heating or your service technician.


6 Radiators.

Are some radiators hot and others cold?

Check that the radiator valves are turned on, that the thermostatic heads are operating correctly and the lockshield valves are open. Is the system balanced properly?Is the top of the radiator cold but the bottom hot – Bleed air from the radiator.

The boiler must be installed in a fixed loca-

tion and only by specialised and qualifiedfirms in compliance with all instructionscontained in this manual.

Furthermore, the installation must be inaccordance with current standards and

regulations.

2.1 INSTALLATION

– These boilers can be installed in all normaldomestic environments as a room sealed

multi function boiler.– These boilers can also be installed in par-

tially covered areas, as per EN 297, with a

maximum ambient temperature of 60°Cand a minimum ambient temperature of -5°C. It is generally advisable to install the

boilers below weathered roofs, on the bal-cony or in a protected niche, to protectthem from exposure to weathering agents

(rain, hail and snow). All boilers provide astandard antifreeze function.

2.1.1 Anti-freeze function

The boilers are equipped with anti-freezefunction which activates the pumps and theburner when the temperature of the water

contained inside the appliance drops tobelow 6°C.

The anti-freeze function is ensured, howe-

ver, only if:- the boiler is correctly connected to the

gas and electricity supply circuits;

- the boiler is constantly fed;- the boiler ignition is not blocked;- the essential components of the boiler

are all in working order.In these conditions the boiler is protected

against frost down to an environmental

temperature of -5°C.

ATTENTION: In the case of installation in a

place where the temperature drops below0°C, the connection pipes must be pro-tected.

2.2 COMPLEMENTARY

ACCESSORIES

To simplify connections to the hydraulic and

gas supplies, it is also possible to use thefollowing accessories:– Mounting plate, code 8101218

– Kit with bends, code 8075423– Kit with faucets, code 8091820

– Solar kit INSOL only for heating boilers,

code 8092235– Mixed area kit ZonaMIX, code 8092234– Ant i f r eeze heaters k i t -15° C, code

8089805.– Hydraulic connection kit boiler/tank unit

code 8091112.

For detailed information on the assembly of

fittings, see the instructions contained in

the box.

2.3 CONNECTING UP SYSTEM

To protect the heat system from damagingcorrosion, incrustation or deposits, before

installation it is extremely important toclean the system using suitable products

such as, for example, FERNOX. Complete

instructions are provided with the productsbut, for further information please contactthe Hunt Heating technical department.

For long-term protection agains corrosionand deposits, the use of inhibitors such asFernox is recommended after cleaning the

system. It is important to check the con-centrat ion of the inhibitor af ter each

system modification and during maintenan-

ce following the manufacturer’s publishedinstructions. The safety valve drain must beconnected to a collection funnel to collect

any discharge during interventions. If theheating system is on a higher floor than theboiler, install the on/off taps supplied in kit

op t iona l on t he heat ing sys temdelivery/return pipes.

WARNING: Failure to clean the heat

system or add an adequate inhibitor inva-lidates the appliance’s warranty.Gas connections must be made in accor-

dance with current standards and regula-tions. When dimensioning gas pipes fromthe meter to the module, both capacity

volume (consumption) in m 3 /h and gasdensity must be taken into account.

The sections of the piping making up the

system must be such as to guarantee asupply of gas sufficient to cover the maxi-mum demand, limiting pressure loss

between the gas meter and any apparatusbeing used to not greater than:

– 1.0 mbar for family II gases (natural gas);

– 2.0 mbar for family III gases (butane orpropane).

An adhesive data plate is sticked inside the

front panel; it contains all the technical dataidentifying the boiler and the type of gas for

which the boiler is arranged.

2.3.1 Connection of condensation

water trap

The drip board and its water trap must be

connected to a civil drain through a pipewith a slope of at least 5 mm per metre to

ensure drainage of condensation water.

The plastic pipes normally used for civildrains are the only type of pipe which isappropriate for conveying condensation

to the building’s sewer pipes.

2.3.2 Filter on the gas pipe

The gas valve is supplied ex factory with an

inlet filter, which, however, is not adequateto entrap all the impurities in the gas or ingas main pipes.

To prevent malfunctioning of the valve, or incertain cases even to cut out the safetydevice with which the valve is equipped,

install an adequate filter on the gas pipe.

2.4 SYSTEM FILLING

Filling of the boiler and the system is done

by the charge system (10 fig. 4). The char-ge pressure, with the system cold, must be

2.4.1 Boiler draining

To drain the boiler turn off the boiler and

use the discharge valve (5 fig. 4).

2.5 INSTALLATION OF

COAXIAL DUCT(ø 60/100 - ø 80/125)

The axial suction and discharge pipes are sup-plied in a special kit (that can be purchasedseparately) along with assembly instructions.

The diagrams of f ig. 6 il lustrate someexamples of dif ferent types of dischargemodal i t ies al lowed and the maximum

lengths that can be reached.

2.6 INSTALLATION OF SEPARATE DUCTS (ø 80 - ø 60)

The kit with dedicated pipes enables toseparate the exhaust fumes pipes from theair suction pipes (Fig. 7):

- The kit with dedicated ø 80 pipes, code.8089912, includes a SUCTION DIAPH-

RAGM THAT IS NOT used for t hese

models. To be able to use the air tap, cutits base with a tool (A) and assemble it

(B).

- The kits with dedicated ø 60 pipes, code8089913, include a suction collar thatreplaces the boiler collar (C).

It is now possible to insert an expansion or

bend in polypropylene without gaskets or

sealant.

The maximum overall length, resulting

from the sum of all the suction anddischarge pipes, is determined by theload losses of the single connected acces-

sories and should not exceed 33.5 PaATTENTION: The total length of each pipe

should not exceed 50M, even if the total

loss is below the maximum exceptableloss.

See Table 1for information on the load los-ses of single accessories.

APREOPEN

IMPORTANT:- The insertion of each additional 90° bend with a diameter of

60/100 reduces the available section by 1.5 meters.- The insertion of each additional 90° bend with a diameter of

80/125 reduces the available section by 2 meters.- Each additional 45° curve installed reduces the available

length by 1.0 metres.- During assembly it is important to make sure that the kit

with axial pipes. (1) is positioned horizontally.

NOTEBefore connecting accessories, it is always advisable to lubrica-te the internal part of the gaskets with silicon products. Avoidusing oils and greases.

3.4 EXTERNAL SENSOR

If there is an external sensor, the hea-ting settings SET can be taken from the

climatic curves according to the exter-nal temperature and, in any case, limi-

ted to with the range values described

in point 3.3 (parameters PAR 25 forzone 1 and PAR 26 for zone 2).The climatic curve to be set can be

selected from a value of 3 and 40 (atstep 1). Increasing the steepness of the curves

of fig. 13 will increase the output tem-perature as the external temperature

decreases.

3.5 CARD FUNCTIONING

The electronic card has the following func-tions:

– Antifreeze protection of the heatingand D.H.W. circuits (ICE).

– Ignition and flame detection system.

– Control panel setting for the power andthe gas for boiler functioning.

– Anti-jamming for the pump which is fed

for a few seconds after 24 hours ofinactivity.

– Antifreeze protection for boilers with

D.H.W. storage tank.– Chimney sweep function which can be

activated from the control panel.

– Temperature which can be shifted withthe external sensor connected. It can be set from the control panel and

is active on the heating systems of bothcircuit 1 and circuit 2.

– Management of two independent hea-

ting circuit systems.– Automatic regulation of the ignition

power and maximum heating.

Adjustments are managed automati-cally by the electronic card to guaran-tee maximum flexibility in use of the

system.– Interface with the following electronic

systems: climatic regulator CR 53,

remote control CR 73, thermal regula-tor RVS, connected to a management

card of a ZoneMIX code 8092234 and

card solar INSOL code 8092235. NOTE: If using CR 53 or RVS set para-meter 10 to 2 (PAR 10 = 2).

3.6 TEMPERATURE

DETECTION SENSOR

Table 4 shows the resistance values of the

heating, DHW and exhaust fumes thermi-stors .

If the heating sensor (SM) is faulty or

open circuit, the boiler will not function oneither heating or D.H.W. (ALL 05).

If the exhaust fumes sensor (SF) is faultyor open circuit, the boiler will not function

on either heating or D.H.W. (ALL 14).

3.7 ELECTRONICIGNITION

Ignition and flame detection is controlled

by a single electrode on the burner whichguarantees reaction in the case of acci-dental extinction or lack of gas within one

second.

3.7.1 Functioning cycle

Burner ignition occurs within max. 10

seconds after the opening of the gasvalve. Ignition failure with consequent acti-vation of block can be due to:

– Lack of gas

The ignition electrode persists in

discharging for max. 10 seconds. If theburner does not ignite, the anomaly is

signalled.

This can happen the first time the boi-ler is switched on after a long period of

inactivity due to the presence of air in

the gas pipesIt can be caused by a closed gas tap orby a broken valve coil (the interruption

does not allow for opening).

– The electrode does not discharge.

In the boiler, only the opening of the gasto the burner can be detected. After10 seconds the anomaly is signalled. It

can be caused by an interruption in theelectrode wire or if it is incorrectlyanchored to the connection points. Or

the electrode may be earthed or stron-gly worn: it must be replaced.

Or the electronic card may be defecti-

ve.

– No flame detected

After start-up the electrode continuesto discharge even when the burner is

on. After 10 seconds, the discharge

stops, the burner is switched off and afault is generated.This fault is sometimes caused by the

shorting of the electrode cable or by itsimproper fixing to the connection

points. The electrode is connected to

the earth or badly worn and must bereplaced. The electronic board is faulty.

In the case of a sudden lack of voltage, theburner will immediately switch off. Whenvoltage returns, the boiler will automatically

start up again.

3.8 WATER FLOW SWITCH

The water flow gauge (15 fig. 3) intervenes,blocking burner functioning, if it detects

that there is insufficient water circulating inthe primary circuit (< 450 l/h).

To res tore burner funct ioning, check

system pressure and the functioning of thepump and the flow switch, and the cleaningof the “Aqua Guard Filter System” filter.

N.B. on system boilers it is important

that if the flow switch assembly is chan-ged, it is fitted with the arrow pointing inthe correct direction.

3.9 HEAD AVAILABLE TO SYSTEM

4.5 MAINTENANCE

To guarantee functioning and efficiency of

the appliance, in respect of the legal provi-

sions in force, it must be regularly checked;

the frequency of the checks depends onthe type of appliance and the installationand usage conditions (refer to the mainte-

nance schedual).In any case, it should be inspected at least

once a year by a qualified technician.

During maintenance operations, it is

important to verify that the drip-plate

with drain trap contains water (thischeck is particularly important if thegenerator has not been used for exten-

ded periods of time).

If necessary, the drip plate can be filled

using the tap provided (fig. 20).

4.5.1 Chimney sweep function (fig. 21)

To check boiler combustion, press the

installer's key for a few seconds. Thechimney sweep function will switch on andwill continue for 15 minutes.

From that moment, the boiler will star t

working in heating mode at maximumpower, with cut off at 80°C and re-ignition

at 70°C (ATTENTION! Temperature may

reach excessive values when using unpro-tected low temperature plants. Beforeactivating the chimney sweep function

make sure that the radiator valves oreventual zone valves are open) .

The test can also be carried out with the

boiler working in sanitary water mode. For this, after activating the chimney sweep

function, open one or more hot water taps.

Under these conditions, the boiler will func-tion at maximum power with the D.H.W. cir-cuit kept at between 60°C and 50°C.

During the test, the hot water taps mustremain open.

If the key and are pressed during

the 15 minutes of the chimney sweep func-tion, the boiler will be brought respectively

to maximum and minimum power.

The chimney sweep function will automa-tically switch off after 15 minutes orwhen the key is pressed again.

4.5.2 Cleaning the filter “Aqua Guard

Filter System” (fig. 22)

To clean the filter, close the delivery/return

on/off taps, turn off the power to the con-trol panel, remove the casing and empty theboiler using the drain provided.

Place a container for collection underneaththe filter, unscrew the cap and proceed to

clean the filter, removing impurities and

limestone deposits. Check the seal o-ring before reassembling

the cap with the filter.
