* H152-2 units are not approved for G30 (Butane) gas.
The size of the gas line used for installation is very important. If the line is too small, the gas pres-
sure at the burner manifold will be low. This may cause slow recovery and delayed ignition. Fry-
master recommends the incoming gas supply line be a minimum of 1½" (38 mm) in diameter. Refer
to the chart on the following page for the minimum sizes of connection piping.
