INSTALLING THE NEW WATER HEATER The water within the water heater tank expands as it is heated and WATER PIPING increases the pressure of the water system. If the relieving point of the water heater’s temperature-pressure relief valve is reached, the valve will relieve the excess pressure. The temperature-pressure relief valve is not intended for the constant relief of thermal expansion. This is an unacceptable condition and must be corrected. It is recommended that any devices installed which

When installed at elevations above 7,700 feet (2,347 meters), input GAS PIPING rating should be reduced at the rate of 4 percent for each 1,000 feet (305 meters) above sea level which requires replacement of the burner orifice in accordance with National Fuel Gas Code ANSI Z223.1/ NFPA 54. Contact your local gas supplier for further information. Failure to replace the standard orifice with a high altitude orifice when installed could result in improper and inefficient operation of the applianc

Never use this water heater unless it is completely full of water. To SEDIMENT TRAPS prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater. To fill the water heater with water: 1. Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater. 2. Open the cold water supply valve to the water heater.

Be sure to remove all burrs from around the inside as well as the outside of the pipe. A slight chamfer (bevel) of about 10°- 15° should be added to the end to permit easier insertion of the pipe into the end of the fitting. Failure to chamfer the edge of the pipe may remove cement from the fitting socket, causing the joint to leak. STEP E F. Joint assembly W
