Safety Instructions Installation Instructions Operating Instructions ! WARNING: Do not attempt to convert this water heater for use with a different type of gas other than the type shown on the rating plate. Such conversion could result in hazardous operating conditions. Gas Supply The branch gas supply line to the water heater should be clean 1/2" black steel pipe or other approved gas piping material. A ground joint union or ANSI design certified semi-rigid or flexible gas appliance connector should be installed in the gas line close to the water heater. The National Fuel Gas Code (NFGC) mandates a manual gas shut-off valve: See (NFGC) for complete instructions. If flexible connectors are used, the maximum length shall not exceed 36". If lever type gas shut-offs are used, they shall be T-Handle type. Compound used on the threaded joints of the gas piping must be of the type resistant to the action of LP gas. Use compound sparingly on male threads only. A sediment trap should be installed at the bottom of the gas line. Do not use excessive force (over 31.5 ft lbs.) in tightening the pipe joint at the gas control (thermostat) inlet, particularly if teflon pipe compound is used, as the valve body may be damaged. The inlet gas pressure to the water heater must not exceed 10.5" w.c. for natural gas, or 14" w.c. for LP gas. For purposes of input adjustment, the minimum inlet gas pressure (with main burner on) is shown on the water heater rating plate. If high or low gas pressures are present, contact your gas supplier for correction. Care and Cleaning Troubleshooting Tips ! WARNING: Never use an open flame to test for gas leaks, as property damage, personal injury or death could result. Leak Testing The water heater and its gas connections must be leak tested at normal operating pressures before it is placed in operation. Turn on the manual gas shut-off valve near the water heater. Use a soapy water solution to test for leaks at all connections and fittings. Bubbles indicate a gas leak that must be corrected. The factory connections to the thermostat should also be leak tested after the water heater is placed in operation. Pressure Testing the Gas Supply System The water heater and its manual gas The water heater must be isolated from shut-off valve must be disconnected from the gas piping system by closing the the gas supply piping system during any manual gas shut-off valve during any high pressure testing of that system at pressure testing of the gas supply piping pressures in excess of 3/8 psi (10.5" w.c.) at pressures equal to or less than 3/8 psi for natural gas, or 1/2 psi (14" w.c.) for LP (10.5" w.c.) for natural gas, or gas. 1/2 psi (14" w.c.) for LP gas. ! WARNING: Failure to install a water heater suitable for the altitude at the location it is intended to serve, can result in improper operation of the appliance resulting in property damage and/or, producing carbon monoxide gas which could result in personal injury, or death. High Altitude Ratings of gas appliances are based on sea level operation and need not be changed for installations at elevations up to 5,999 feet. For installations above 5,999 feet, please contact your local distributor or place of purchase for a high altitude model. 11 Customer Service
