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.

9.Install a coupling, nipple, union and sediment trap onto the right-hand end of the main gas line and then install the gas line, making sure that a manu- al shut-off valve has been installed within 10 ft of the heater.

10.Replace the left and right front panels on the heater.

Gas Supply Pressure

A minimum of 5.0 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 11.0 in. WC and a maximum of 13.0 in. WC is required for propane gas. The gas pressure regulator(s) supplied on the heater is for low-pressure service. If upstream pressure exceeds 14.0 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 for the combined load.

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. 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 adjust- ment is needed, remove the adjustment screw cover and turn the adjustment screw clockwise to increase pressure or counter-clockwise to lower pressure.
