GAS Connections

The gas supply lines must meet all requirements of the National Fuel Gas Code, ANSI Z223.1 - (Latest Edition) and/or in Canada, CAN/CGA B149 Installation Codes - (Latest Editions).

The minimum permissible gas supply pressure for the purpose of input adjustment is one (1.0) inch (.25kPa) water column above the operating manifold pressure. See the rating plate and combination gas control for the manifold pressure and gas type. The maximum permissible gas supply pressure is fourteen (14.0) inches (3.5kPa) water column for natural gas and liquefied petroleum gases/propane gas.

1.Connect this water heater only to the type of gas (natural or propane gas) as shown on the rating plate. Use clean 1/2 inch black iron

pipe. (Dirt and scale from the pipe can enter the combination control and cause it to malfunction). The inlet gas line must have a drip leg (sediment trap) installed as close as possible to the water heater’s combination gas control having a minimum length of three (3) inches (7.6 cm). A ground joint union must be installed in the gas supply line feeding the water heater to permit servicing of the water heater. Compounds used on the threaded joints of the gas piping must be resistant to the action of liquefied petroleum gases/propane gas.

2.This water heater and its gas connection must be leak tested before placing the water heater in operation. Check for gas leaks with a soap and water solution and a brush or a commercial leak detector fluid. NEVER USE A MATCH OR OPEN FLAME FOR TESTING!

CAUTION

The water heater and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of 1/2 psi (3.5 kPa). The water heater must be isolated from the gas supply piping system by closing its manual shutoff valve during any pressure testing of the gas supply system at test pressures equal to or less than 1/2 psi (3.5 kPa). The supply line must be capped when not connected to the water heater.
