Gas Supply Connection

CAUTION: The heater must be disconnected from the gas supply during any pressure testing of the gas supply system at test pressures in excess of 1/2 psi (3.45 kPa).

The heater must be isolated from the gas supply pip- ing system by closing the manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.45 kPa). Relieve test pressure in the gas supply line prior to 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 cov- ered 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 an open flame.

CAUTION: Do not use Teflon tape on gas line pipe thread. A pipe compound rated for use with natural and propane gases is recommended. Apply sparingly only on male pipe ends, leaving the two end threads bare.

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

Reversing Gas Supply Connection

Reversing the standard fuel connection from the left- hand to the right-hand side is a simple field operation.

1.Disconnect all electrical power from the heater (if applicable).

2.Disconnect the main gas pipe from the heater (if applicable).

3.Remove the left and right front panels from the heater.

4.Locate the main gas line that traverses across the heater above the manifold risers.

5.Remove the pipe cap from the right-hand end of the main gas line.

6.Reinstall the pipe cap on the left-hand end of the main gas line.

7.Remove plastic cap from the right-hand side panel and reinstall into the standard main gas opening located on the left-hand side of the heater.

8.Remove the rubber grommet from the left-hand- side panel and reinstall into the standard main gas opening, located on the right-hand side of the heater.
