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).

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.
