CAUTIONShould over heating occur, or the gas supply fail to shut off,turn off the manual gas valve to the appliance immediately.
A. INSTALLATION(1) THIS SECTION ADDRESSES THE INSTALLATION OF ACE BOILER INC. WATER HEATERS WITHIN MECHANICAL SYSTEMS, AND IS INTENDED
TO PROVIDE SOME EXPLANATION OF NORMAL SYSTEM HOOK-UP AND OPERATION AS WELL AS DESCRIPTIONS OF SOME COMMONLY
ENCOUNTERED SYSTEM PROBLEMS AND SOLUTIONS.(2) Install the heater in accordance with the following instructions. A qualified installation company should always be used.(3) The heater must be installed in accordance with all state and local codes, and all national codes, including, but not limited to:
· ANSI Z21.10.2, GAS WATER HEATERS· ANSI Z223.1, NATIONAL FUEL GAS CODE· ANSI / NFPA 70, NATIONAL ELECTRIC CODE.
(4) Install per heater-tank diagram located on page 4.(5) Connect the piping to draw cool water from the lower portion of the tank through the circulating pump to the bottom inlet heater connection. If a flow switch
is used it should be connected near the pump outlet.(6) Connect the hot water return line from the heater to the tank as shown in the hook-up diagram.(7) Connect the cold water inlet supply directly into the tank as shown in the hook-up diagram. Do not use a check valve on the cold water inlet line. If a
check valve is installed in the cold inlet line then a properly sized expansion tank should be added to the system to prevent the relief valve from popping.(8) The hot water outlet line should be connected at the highest part of the tank to avoid air entrapment, which can cause rapid corrosion at the top of the tank.(9) Install a thermometer, a drain valve, and a relief valve (anode if required) on the tank as shown in the hook-up diagram.
(10) Page 4 illustrates a normal installation for a single heater with a storage tank. Cold water is supplied to the storage tank while systemhot water is drawn from the top of the storage tank. Water is supplied to the water heater by a circulating pump which is normally wiredto operate on a continuous basis. Return Water temperature must be above 140 degrees F to avoid condensation damage.
Note: Page 4 depicts piping schematics for multiple heater installations with vertical and horizontal storage tanks.
B. IDENTIFICATION(1) Your Ace Water Heater carries two identification plates. The coil plate, which carries the ASME Code Stamping and Registration Number (when applica-
ble) is attached to the coil just inside the upper manifold assembly. The boiler nameplate lists information concerning the input and output of the unit, elec-trical and gas ratings, working pressure and clearance to adjacent construction figures. In addition the model and serial numbers are on the plate. You willneed these to order replacement parts from the manufacturing representative in your area or from the factory.
(2) The information on the National Board plate is the same as on the name plate with the exception of the National Board registration number, which isrequired in most states for installation of the unit.
Do not remove either of these plates from the unit for any reason.
C. LOCATION(1) Set the heater on a non-combustible floor. If the floor is combustible, a special "Combustible Floor Base" (CFB) must be used. Locate the heater so that leakage from tank or
connections will be directed to a floor drain and will not damage adjacent area or lower level floors.(2) The minimum clearance between a heater and a storage tank is 6". For multiple heater installations a minimum of 6" clearance between heaters shall be
maintained. For alcove installation, the minimum clearance to combustible construction is 24" to side and rear walls and 36" from the top of the heater tothe ceiling. The front of the alcove shall remain open. Local and state codes may require greater clearances.
(3) Allow sufficient space in front of heater for cleaning and removal of burners, replacement of the draft hood and controls, and the adjustment of all parts requiring such attention.Keep the area around the heaters free from combustibles and flammable liquids.
(4) Minimum ventilation and combustible air openings to the room in which the heater is located must be provided in accordance with NATIONAL FUEL GAS CODEANSI Z21.13.
D. COMBUSTION AND VENTILATION AIR
CAUTIONThe lack of adequate combustion air is the single biggest
problem encountered with gas fired water heaters.
(1) Ace recommends that two permanent openings to outside air be provided, one 6" from the floor and the other 6" from the ceiling. The combined area ofthe two openings should not be less than 200 sq. in. for the first 100,00 BTUH heater input, and 100 sq. in. for each additional 100,000 BTUH heater input.
(2) All additional gas fired equipment should be considered when calculating the necessary air supply.(3) The openings should have permanent, non-adjustable louvers properly designed so that they provide a baffling effect under wind conditions. Wood louvers may be consid-
ered to have 20-25% free area, and metal louvers may be considered to have 60-75% free area.(4) It is important to locate the heaters so that they are not adversely affected by wind, draft or freezing conditions that may exist in the room.(5) Air may be supplied by the use of ducting, fans, etc. It is extremely important, however, that any system be designed and installed by a qualified profes-
sional in such a manner that no positive or negative air pressure exists in the room in which the heaters are installed. Such a problem will result in improp-er combustion and sooting problems.
(6) Required draft at the outlet stack must be within the range of -.02 to -.04 inches water column.
E. ELECTRICAL CONNECTIONS(1) A junction box is provided on the heater jacket for the electrical service connection.(2) For multiple heater installations, each heater is to be wired in parallel with all the other heaters so that each heater will operate independently.(3) The circulating pump (and the return pump if used) should be wired in parallel with the heater(s) to run continuously.(4) The heater(s) when installed, must be electrically grounded in accordance with state and local codes and in accordance with the NATIONAL ELECTRICAL
CODE ANSI / NFPA 70-1984.(5) If any of the original wiring as supplied with the heater/boiler is replaced, it must be replaced with 18" AWG TFF wire or its equivalent.
INSTRUCTIONSFor Ace Gas Fired Copper Fin Volume Water Heaters
SECTION 250CONTINUED
SECTION 250CONTINUEDF. RELIEF VALVES
(1) The storage tank should be protected with a pressure (or combination temperature and pressure) relief valve set so as not to exceed the maximum tank operating pressure. The relief valve should be located within 6" of the top of the tank. Refer to local codes for the type of relief valve required.
(2) Each heater should be protected with its own pressure relief valve. The relief valve should be rated for the BTU/hr or LBS/hr of heater output.(3) The pressure relief valves and pressure relief elements of combination valves, when supplied, shall comply with applicable performance provisions of the
American National Standard for Relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22-1979.(4) Manually operate relief valves at least once a year.(5) If the temperature and pressure relief valve(s) on the appliance(s) discharge periodically, a problem exists and service to the water system is required. Periodic
discharge may be due to thermal expansion in a closed water system.
CAUTION!!!To prevent scalding and/or personal injury, pipe outlet of relief valve(s)
to a floor drain with NO intervening valves or restrictions.
G. AIR ELIMINATION(A) All of the air must be removed from the water piping in the system before the system will function properly. Therefore, all high points in the system must be
vented or purged. Relief valves may be used to purge air when they are at the high point.(B) If a water heater is installed in a closed water system, contact the water heater supplier or local plumbing inspector on methods to allow proper system expan-
sion. A weeping pressure or temperature relief valve may be due to thermal expansion (i.e. expansion tanks) in a closed water system. Do not plug the tem-perature and pressure relief valve.
H. VENTING SYSTEM (FLUE GASES)(1) Vents for the heater(s) may be run individually or manifolded. Two or more heaters may be vented through a common vent connector or manifold. The common vent
connector or manifold shall be located at the highest level consistent with available head room or clearance to combustible material, and shall be sized in accordance withapproved engineering methods. The area of the common vent connector or manifold shall not be less than the combined area of the individual draft hood outlets or theindividual vent connectors.
See the NATIONAL FUEL GAS CODE ANSI Z21.13-1984 Section 1.5 "Venting of Appliances" for more detailed information.
(2) Only locally approved code type venting should be installed.(3) The draft hood furnished with each heater/boiler must be installed as shown on the hook-up diagram.(4) The sheet metal collar included with the heater musted be installed between the heater & the draft hood.
I. GAS CONNECTION(1) The gas line should be a separate line running directly from the gas meter to the heater, unless the existing gas line is of ample capacity. Verify the capacity of
the existing gas piping if it is to be used.(2) Install a union at the connection to the heater manifold.(3) Refer to the rating plate on the shell of the heater for proper gas manifold pressure. The manifold pressure is measured downstream of the gas pressure regu-
lator. Do not exceed the maximum gas pressure specified on the rating plate.(4) A trap (drip leg) must be installed upstream of the gas pressure regulator.(5) The heater must be disconnected from the gas supply piping system during any pressure testing of the gas supply piping.(6) Gas connections and heater should be properly tested for leaks before being put into operation.(7) Gas supply lines should be purged of air at the heater before startup.(8) The flow rate is determined by controls preset at the factory. There is no field adjustment for the minimum input rate.
J. TESTING(1) Your heater has been pressure tested in accordance with ASME CODE SECTION IV and fire tested in accordance with U.L. 795.(2) It is recommended that the heater and the system into which it is installed be tested before operating the system. The exact nature of the test(s) are deter-
mined by the system's component(s), but will generally consist of a water pressure test and a gas leak test. This testing should be completed as part of thenormal installation procedure by the installing company.
(3) Once the entire installation is complete, the unit should have an operation test to insure that the ignition system safety shut of device works properly.Instructions in the manufacturer's literature shall be followed in conducting this test.
K. MAINTENANCE
CAUTIONThe following inspections and tests should be performedat regular intervals at least every three to six months.
Failure to do so may void your warranty.
(1) Turn the Operating Thermostat and High Limit Aquastat down, then up until heater turns off and on to verify that the controls are operating satisfactorily.(2) Check the High Limit Aquastat Well for lime. If 1/16" lime is deposited on the outside of the well, the coil needs to be delimed.(3) Inspect the coil and burner assembly to make sure that they are free from dust, lint, dirt, etc. If they are dirty, remove all foreign material by washing, flushing,
or air cleaning, etc.(4) Inspect venting system to make sure that it is free of dirt and corrosion.(5) Make periodic visual checks of burners and pilot flames.(6) Check combustion air inlets in the room to see that they are clear of obstructions.
L. AQUASTAT INFORMATION(1) The Heater is equipped with two aquastats - a high limit safety aquastat in the upper (hot out) manifold and an operating aquastat (Thermostat ) in the lower
(tank water in) manifold. The operating aquastat “Thermostat” should be set approximately 10°F lower than the desired tank tamperature setting. The HI limitaquastat should be set at least 60°F higher than the thermostat setting. For example: if desired water temperature in tank is 140°F set the thermostat at130° F and Hi limit at 200°F; for 150°F tank water temperature set the thermostat at 140°F and the Hi limit at 210°F. etc. When 2 or more heaters are operatedtogether, set the 2nd heater thermostat 3° to 5° lower than the first heater thermostat and the third heater thermostat 3° to 5° lower than the 2nd heater thermo-stat, etc. Check the tank thermometer and correct thermostat so that the heater shuts off at desired tank water temperature. Note: tank aquastat may be used interchangeably with the heater operating aquastat.
(2) Water entering heater below 140 °F will cause the heater to condense, limiting its service life.

DELIMING PROCEDURE — Connect ACE deliming kitas shown in picture.
1. Close gas cock at heater.
2. Turn off water to and from heater and drain heater.
3. Type “C” ACE Heater, remove upper aquastat andwell and install faucet; Type “D”, “E” and "G" ACE
Heater, remove pipe plug on left side of upper heatermanifold and install faucet.
4. Attach hose from pump to top faucet and return hosefrom acid container to lower faucet as shown in pic-ture.
5. Pour water into plastic container and add equalamount of acid. Approximately 4 gallons of dilutedsolution is required for 400,000 BTU and smallerheaters, 5 gallons to 7 gallons for heaters up to760,000 BTU and 9 gallons for heaters between1,000,000 and 1,500,000 BTU.
6. Turn on pump and circulate solution until foamingaction of the solution stops indicating that dissolvingof the lime has been completed. Add approximatelyan additional quart of solution to insure that end offoaming is not due to spent acid. Do not continue topump acid solution for a prolonged time after foam-ing stops because the acid will dissolve the copperand brass.
7. Flush heater out with baking soda and water solutionand return it to service.
In case of a completely plugged coil it is recommendedthat a heater serviceman be called in to do the deliming.
CAUTION! AVOID SPILLING OR DRIPPING ACID ON HANDS,FACE, CLOTHING OR ELECTRICAL CONTROLS OR WIRING.COVER CONTROLS WITH PLASTIC SHEETING SUCH AS SARAN,OR POLYETHYLENE BAG, TO AVOID DAMAGE TO THESE PARTS.USE A BAKING SODA AND WATER SOLUTION TO NEUTRALIZE
ANY ACID ON HANDS, FACE, CONTROLS, ETC.
NON-ACID DELIMING SOLUTION — For those pre-ferring to use a non-acid base solution, it will be notedthat the effectiveness of such a solution is shorter-livedthan regular acid and usually requires more stock solu-tion. Such a solution, called “LIMINAL”, may beobtained from Polyteck Co., 5112 W. Jefferson Blvd.,Los Angeles, Calif. 90016. Also in the eastern areascontact Tri-Bros. Chemical Corp., P.O. Box 2, MortonGrove, Illinois 60053 for solution called “Lime Eater”.
Water heaters that use fresh water will develop a coat-
ing of lime if the fresh water is not softened or if it is not
naturally free from undissolved solids. When a water
softener does not function properly, due to lack of ser-
vicing or due to undersizing, the heater will develop
lime.
Inspection of Heater — Check heater every 6 months
by closing water plug cocks, and removing high limit
aquastat well, located in top manifold, and visually
inspect the inside of the coil for lime. ACE recommends
deliming if 1/32" or greater thickness of lime is found. If
recovery rate of heater falls off, this is usually a sign of
lime in the coil. The ACE coil will “bang” or “knock” if lim-
ing condition is severely restricting circulation.
Customers have reported operating ACE heaters and
softeners under heavy duty laundry service for 10 to 15
years without the need to delime or change the ACE
conical coil. Under moderate water hardness condi-
tions, ACE users have found that when operating with-
out a softener that deliming once a year could be
accomplished in approximately one hour.
For deliming, use solution of muriatic acid (which can be
purchased from any drug or pool supply store) and
dilute with equal amount of water to obtain a 50% solu-
tion for normal deliming. Caution: Always add acid to
water when diluting. Adding water to acid can result in
splashing and acid burns. If coil has a heavy coating of
lime, use only 10% solution of acid of acid to start with
to prevent chunks of lime from breaking loose and plug-
ging the coil before dissolving.
Deliming Kit
EFFECTIVE — AC E single coi l , noparal le l tubes, insures that a l l
l ime is removed
FAST — Simple hook up and sin-gle coi l a l lows del iming to be
accomplished in one hour or lessunder normal
condit ions
ECONOMICAL — Acid costsshould not exceed $15.00 on
largest heater. Muriatic acid canbe purchased at most drug stores or
pool supply dealers.
