COMMERCIAL GAS Lined Tank Type Water Heater • Installation • Service • Maintenance CAUTION TEXT PRINTED OR OUTLINED IN RED CONTAINS INFORMATION RELATIVE TO YOUR SAFETY. PLEASE READ THOROUGHLY BEFORE INSTALLING AND USING THIS APPLIANCE. PLACE THESE INSTRUCTIONS ADJACENT TO HEATER AND NOTIFY OWNER TO KEEP FOR FUTURE REFERENCE. PRINTED IN U.S.A. 1102 PART NO.
FEATURES AND SPECIFICATIONS The illustration shows a typical gas-fired commercial gas power burner, tank-type water heater. The principal components of the heater are shown and identified here. By referring to the plate on the heater jacket the unit may be identified in the specifications presented in Table 1 and 2.
FOREWORD THESE HEATERS MUST NOT BE INSTALLED DIRECTLY ON COMBUSTIBLE FLOORS. These designs comply with the latest version of the American National Standard for Gas Water Heaters, Volume III, ANSI Z21.10.3 - CSA 4.3. In addition to these instructions, the equipment shall be installed in accordance with those installation regulations in force in the local area where the installation is to be made. These shall be carefully followed in all cases.
Spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride (water softener salt), waxes, and process chemicals contain typical compounds which are potentially corrosive. Do not store products of this sort near the heater. Also, air which is brought in contact with the heater should not contain any of these chemicals. If necessary, uncontaminated air should be obtained from remote or outside sources.
The input reduction is primarily achieved by reducing the size of the main burner orifices. To do this, the main burner orifices require replacement with orifices sized for the particular installation elevation. Correct orifice sizing and parts may be obtained from the manufacturer. See the REPLACEMENT PARTS section of this manual. When ordering, be sure to state the model number and the altitude of the location where the heater is being installed.
ARE HEAVY AND TRAVEL ALONG THE FLOOR AND MAY BE IGNITED BY THE HEATER’S IGNITION SYSTEM OR MAIN BURNER FLAMES CAUSING FIRE OR EXPLOSION. SOME LOCAL CODES PERMIT OPERATION OF GAS APPLIANCES IN SUCH AREAS IF THEY ARE INSTALLED 18 INCHES OR MORE ABOVE THE FLOOR. THIS MAY REDUCE THE RISK IF LOCATION IN SUCH AN AREA CANNOT BE AVOIDED.
CARBONING OR SOOTING OF THE COMBUSTION CHAMBER, BURNERS AND FLUE TUBES AND CREATES A RISK OF ASPHYXIATION. figure 4. The outlet of the draft control assembly may be rotated to face in direction needed. The assembly must be fitted to the jacket cover such that it is plumb and level to the ground. Fasten the draft control assembly to the top cover using sheet metal screws at three locations, or more, as required.
Occasionally, some water seepage will occur at a cleanout port. To correct this situation, slightly tighten the cleanout cover bolts until the seepage is eliminated. Do not overly tighten the bolts or the cleanout gasket will be damaged. Tighten each bolt gradually and alternate between opposed bolts on the cleanout cover. In venting systems where a continuous or intermittent back (positive) draft is found to exist, the cause must be determined and corrected.
TABLE 4 MAXIMUM CAPACITY OF PIPE IN CUBIC FEET OF GAS PER HOUR WARNING THE HEATER IS NOT INTENDED FOR OPERATION AT HIGHER THAN 10.5" W.C. - NATURAL GAS, 13.0" W.C. - PROPANE GAS (1/2 POUND PER SQUARE INCH GAUGE) SUPPLY GAS PRESSURE. HIGHER GAS PRESSURES REQUIRE SUPPLEMENTAL REDUCING SERVICE REGULATION. EXPOSURE TO HIGHER GAS SUPPLY PRESSURE MAY CAUSE DAMAGE TO THE GAS CONTROLS WHICH COULD RESULT IN FIRE OR EXPLOSION.
With the power burner installed in the heater, the electrical wiring can be completed. On ***81-140 and ***81-199 models, remove the power burner backplate and fasten the conduit assembly to the power burner assembly. Next, connect the black wire to the terminal marked “1” and the white wire to the terminal marked “2”. to installation diagrams on pages 12-16 of this manual for suggested piping arrangements.

MANIFOLD KITS Precision cut type “L” all copper manifold kits from your manufacturer assure water flow balance of all units. Without this balance, the full water heating and storage potential of the system cannot be achieved. Plus, the units with the higher water flow may have a shortened life. Unions shown in piping diagrams are not included in the manifold kits. Dimensions shown are for minimum space occupied by the water heaters assemblies.
• Drill max. 5/16" hole in breeching as close as possible to flue connection on heater to install stack thermometer and combustion analyzing equipment. (See fig. 4). PRIOR TO START UP IMPORTANT • You are now ready to begin the burner start up procedure. IT IS REQUIRED THAT A QUALIFIED PERSON PERFORM THE INITIAL FIRING OF THE HEATER. AT THIS TIME THE USER SHOULD NOT HESITATE TO ASK THE INDIVIDUAL ANY QUESTIONS WHICH HE MAY HAVE IN REGARD TO THE OPERATION AND MAINTENANCE OF THE UNIT.
OPERATIONAL AND ADJUSTMENT PROCEDURE (INITIAL START UP) FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY, A FIRE OR EXPLOSION MAY RESULT CAUSING PROPERTY DAMAGE, PERSONAL INJURY OR LOSS OF LIFE. A. THIS APPLIANCE DOES NOT HAVE A PILOT. IT IS EQUIPPED WITH AN IGNITION DEVICE WHICH AUTOMATICALLY LIGHTS THE BURNER. DO NOT TRY TO LIGHT BURNER BY HAND. B. BEFORE OPERATING SMELL ALL AROUND THE APPLIANCE AREA FOR GAS.
TABLE 5 Temperature Setting o180°F (82°C) 170°F (77°C) 160°F (71°C) 150°F (65°C) 140°F (60°C) 130°F (54°C) 120°F (49°C) This is an acceptable input rate for a ***81-270, installed at an altitude up to 2000 feet, as it is within 2% of the rated input. For installations at higher altitudes, the input will be less for the reasons explained in the FOREWORD.
1. Turn off the heater electrical disconnect switch. 6.Check main burner operation by cycling on and off the thermostat dial several times. Wait 1 minute between cycles for regulators and sequencing to reset. 2. Close the cold water inlet valve to heater. 3. Open a nearby hot water faucet to vent the system. 7. When all adjustments are satisfactory: 4. Open the heater drain valve. • Fill in part no. 170037 “Start-up” form.
To clean heater through cleanout opening, proceed as follows: POWER BURNER 1. Turn off water inlet valve, the heater electrical disconnect switch and open drain valve. Keep the area around the burner clear and free of combustible materials, gasoline or other flammable liquids or vapors. Do not obstruct burner air openings or ventilation grilles for combustion air. 2. Remove outer cover plate from lower side of heater jacket. 3. Remove cover from cleanout opening. 4.
To test gate for operation gently tap gate and observe. DO NOT ATTEMPT TO ADJUST THIS CONTROL. DO NOT OIL. 4. Colder incoming water temperature will lengthen the time required to heat water to the desired temperature. • If the heater was installed when incoming water temperature was warm, colder water creates the effect of less hot water. ANODE ROD INSPECTION The heater tank is equipped with anode rods to provide corrosion control.
• • 1. Motor relay drops out due to low voltage. • Check valve circuit for ground or overload. Installation of a second relief valve with lower setting than the primary relief valve. An expansion tank of suitable size and pressure rating and provision to avoid water logging. MOTOR RUNS CONTINUOUSLY, PREPURGE TIME ELAPSES, BUT NO FLAME PRESENT HOT WATER ODOR Electric check only (no trial for flame). On occasion, hot water may develop a strong odor.
