SECTION 7: GAS SERVICE INSTALLATION 7.1 Install Gas Supply Lines

A 3/8" gas supply connection is required as shown in Figure 32. To check system pressure, a plugged 1/8" NPT tapping is required upstream of the manual gas shut-off valve supplied with the heater.

Before connecting the heater to the supply system, (Figure 32) verify that all high pressure testing of the gas piping has been completed. Do not high pres- sure test (greater than 1/2" psi/3.5 kPa) the gas piping with the burner connected. The appliance must be isolated from the gas piping system by clos- ing manual gas shut-off valve during any pressure testing at pressures less than or equal to 1/2" psi (3.5 kPa).

FIGURE 32: Gas Supply Lines

Follow these instructions to ensure a safe gas supply system installation:

1.Support all gas piping with suitable pipe hanging materials.

2.Use wrought iron or wrought steel pipe and mal- leable iron fittings. The use of copper tube and brass fittings is acceptable when such use is in compliance with local codes. All pipe, tube and fit- tings should be new and free from defects. Care- fully ream the pipe and tube ends to remove obstructions and burrs.

3.Use LP gas resistant joint compound on all threads.

4.Check the pipe and tube connections for leaks before placing heating equipment into service. When checking for gas leaks, use a soap and water solution; never use an open flame.
