Connecting the gas piping to the gas control valve of the water heater can be accomplished by either of the two methods shown in Figures 15 and 16.
SEDIMENT TRAPS
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 15, 16 and 17.

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 Z223.1/NFPA 54.
FUEL CONVERSION INSTRUCTIONS FROM NATURAL GAS TO PROPANE (L.P.) GAS
Fuel conversions shall be completed by a qualified service agency in accordance with the detailed conversion instructions and all applicable codes and requirements of the authority having jurisdiction. The information in these instructions must be followed to minimize the risk of fire or explosion and to prevent property damage, personal injury or death. The qualified service agency is responsible for the proper installation of this kit. The installation is not proper and complete until the operation of the appliance is checked as specified in the manufacturer’s instructions.
1.Read and follow detailed conversion instructions below and also on the heater.
2.The conversion kit with necessary parts are in a bag attached to the side of the water heater.
3.Shut off the gas supply to the water heater.
4.Remove the outer door.
5.Rotate the thermostat dial on the water heater control counterclockwise (
) until the main burner ignites and burns off all residual gas in the control and supply lines.
6.Rotate the thermostat dial clockwise (
) back to the “PILOT LIGHTING” position.
7.Turn the gas control knob “A” to “PILOT”. Depress knob slightly and rotate to “OFF” position, see Figure 18.
