INSTALLATION
Connection to Gas Line
The size of the gas line used for installation is very important. If the line is too small, the gas
pressure at the burner manifold will be low. This may cause pilot outage, slow recovery and
delayed ignition. The incoming gas supply line should be a minimum of 1½” (38 mm) in
diameter. Refer to the chart below for the minimum sizes of connection piping.
