Gas Supply Connection

CAUTION: The heater and its manual shutoff valve must be disconnected from the gas supply during any pressure testing of the gas supply system at test pressures in excess of 1/2 PSIG (3.45 kPa). The heater must be isolated from the gas supply piping system by closing the manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 PSIG. Relieve test pressure in the gas supply line before reconnecting the heater and its manual shut off valve to the gas supply line. FAILURE TO FOLLOW THIS PROCEDURE MAY DAMAGE THE GAS VALVES. Over pressurized gas valves are not covered by warranty. The heater and its gas connections shall be leak tested before placing the appliance in operation. Use soapy water for leak test: DO NOT use open flame.

CAUTION: Do not use Teflon tape on gas line pipe thread. A pipe compound rated for use with gas systems is recommended. Apply sparingly only on male pipe ends.

CAUTION: Support gas supply piping with hangers, not by the heater or its accessories. Ensure the gas piping is protected from physical damage and freezing where required.

Gas Supply Pressure

A minimum of 7 in. WC and a maximum of 10.5 in. WC upstream gas pressure is required under load and no load conditions for natural gas. A minimum of 11 in. WC and a maximum of 13 in. WC is required for propane gas. The gas pressure regulator supplied on the heater is for low pressure service. If upstream pressure exceeds 14 in. WC, an intermediate gas pressure regulator, of the lockup type, must be installed.

When connecting additional gas utilization equipment to the gas piping system, the existing piping must be checked to determine if it has adequate capacity.

Gas Pressure Regulator

The gas valve pressure regulator(s) on the heater are nominally preset at 3.5 in. WC for natural gas, and

10.5in. WC for propane gas manifold pressure. The pressure at the gas valve outlet tap, measured with a manometer,while in operation should be 3.5 ± 0.1 in. WC for natural gas and 10.5 in. ± 0.1 in. WC for propane gas. If an adjustment is needed, turn the adjustment screw clockwise to increase pressure or counter-clockwise to decrease pressure.
