Figure 5: Gas Connection
Failure to follow this procedure may damage the gas valve. Over pressured gas valves are not covered by
warranty.
Do not use Teflon tape on gas line pipe threads. A flexible sealant suitable for use with natural gas and
propane gas is recommended.
Plan gas supply piping so that it will not interfere with removal of gas valves, blower assemblies, and front or
side service doors.
All gas piping should be adequately supported to prevent any strain on inlet piping.
The gas valve is provided with pressure taps to measure gas pressure upstream and downstream, (manifold
pressure). The minimum gas pressure shown is for the purpose of input adjustment.
A 1/8" NPT plugged tapping, accessible for test gage connection, must be installed immediately upstream of
the gas supply connection to the appliance.
