For installation above 2,000 feet (610 m), the water heater's Btu input should be reduced at the rate of 4 percent for each 1,000 feet (305 m) above sea level which requires replacement of the burner orifice in accordance with the National Fuel Gas Code ANSI Z223.1/NFPA 54. Contact your local gas supplier for further information. Failure to replace the standard orifice with the proper high altitude orifice when installed at elevations above 2,000 feet (610 m) could result in improper and inefficient operation of the appliance, producing carbon monoxide gas in excess of the safe limits. This could result in serious injury or death. Contact your local gas supplier for any specific changes that may be required in your area. Fire and Explosion Hazard - Contaminants in gas lines can cause fire or explosion. • Clean ail gas piping before installation. - Install drip leg in accordance with NFPA 54. Contaminants in the gas lines may cause improper operation of the gas control valve that may result in fire or explosion. Before attaching the gas line be sure that all gas pipe is clean on the inside. To trap any dirt or foreign material in the gas supply line, a drip leg (sometimes called a sediment trap) must be incorporated in the piping. The drip leg must be readily accessible. Install in accordance with the Gas Piping section. Refer to the current edition of the National Fuel Gas Code, ANSI Z223.1tNFPA 54. A sediment trap shall be installed as close to the inlet of the water heater as practical at the time of water heater installation. The sediment trap shall be either a tee fitting with a capped nipple in the bottom outlet or other device recognized as an effective sediment trap. If a tee fitting is used, it shall be installed in conformance with one of the methods of installation, shown in Figures 19 and 20. Fire and Explosion Hazard • Use joint compound or tape compatiblewith propane. Leak teat before operating heater. -Disconnect gas piping and shut-off valve before pressure testing system (OPTIONAL) GROUUNNDIONJOINT1!_ 3" MIN. I (76.2 mm) DRIP LEG SEDIMENT TRAP) GAS CONTROL VALVE Use pipe joint compound or Teflon tape marked as being resistant to the action of petroleum (Propane [L.P.]) gases. The appliance and its gas connection placing the appliance in operation. must be leak tested before The appliance and its individual shutoff valve shall be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 pound per square inch (3.5 kPa). It shall be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 pound per square inch (3.5 kPa). Connecting the gas piping heater can be accomplished in Figures 19 and 20. to the gas control valve of the water by either of the two methods shown ® TEFLON is a registered trademark of E.I.
