INCLUDING TPX/TPO & TPD COMMERCIAL GAS, OIL AND GAS/OIL TANK-TYPE WATER HEATERS • INSTALLATION • OPERATION ASME Water heaters for propane gas are different from natural gas models. A natural gas heater will not function safely on propane gas and no attempt should be made to convert a heater from natural gas to propane gas. Propane gas must be used with great caution.
This manual is intended to be used in conjunction with other literature provided with the heater. This includes power burner and related gas control information. It is important that this manual and the additional publications be reviewed in their entirety before beginning any work.
GENERAL SAFETY INFORMATION PRECAUTIONS DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN UNDERWATER.

IF THE UNIT IS EXPOSED TO THE FOLLOWING, DO NOT OPERATE HEATER UNTIL ALL CORRECTIVE STEPS HAVE BEEN MADE BY A QUALIFIED SERVICEMAN.
Note: Some gas utility companies derate the heating value of the supplied gas at high elevations. Your authorized State Start-Up Agent must adjust for actual heating valve of the gas at the time of start-up. FEATURES WATER TEMPERATURE CONTROL WARNING THIS WATER HEATER IS EQUIPPED WITH AN ADJUSTABLE THERMOSTAT TO CONTROL WATER TEMPERATURE.
The latest version of the National Electrical Code, NFPA No. 70. In Canada refer to Canadian Electrical Code C 22.1, from National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269-9101. LOCATING THE HEATER When installing the heater, consideration must be given to proper location.
UNDESIRABLE OPENINGS, CAUSING POOR COMBUSTION. SOOTING MAY RESULT WITH AN INCREASED RISK OF ASPHYXIATION. THERMAL EXPANSION (CLOSED SYSTEM) Thermal expansion occurs in any hot water system when system water is heated or “recovered” during periods of non-use. If the system is operated in an “open” condition such as being connected directly to the city main, the volume of expanded water generated during the recovery periods can be dissipated back through the “open”...

The Authorized Start-Up Agent will when they come out to start-up the unit(s) complete one of the following forms for each unit you have and submit it to State Industries to activate your warranty: Start-Up Covering Models Form No.
Suggested safety device test procedures are: A. While heater is operating, turn valve, main burner and pilot gas line manual gas cocks to the OFF position. Burner should shutdown within 3-4 seconds and lockout on flame failure, requiring reset of the flame safeguard device. B.
The depth of lime build-up should be measured periodically. Heaters will have about 3” of lime build-up when the level of lime has reached the bottom of the cleanout opening or about 1” of lime build-up if it has reached the drain valve opening. A schedule for deliming should be set-up;...
6. Using a wire brush, remove soot from flue passages in heater tank. CAUTION While cleaning tank flue passages, care must be taken that brush does not come in contact with the combustion chamber lining as damage could occur. • If burner flue collector flange gaskets are damaged, replace. VENT SYSTEMS Examine the vent system every six months for obstruction and/or deterioration of vent piping.
Excessive water pressure is the most common cause of relief valve leakage. It is often caused by a “closed system”. If a check valve is in the inlet system it will not permit the expanded hot water volume to equalize pressure with the main. The relief valve must release this water or the water heater or plumbing system will be damaged.
