Welbilt Frymaster FilterQuick 3FQG30U Installation, Operation And Maintenance Manual page 17

All connections must be sealed with a joint compound suitable for the gas being
used and all connections must be tested with a solution of soapy water before light-
ing any pilots.
Never use matches, candles, or any other ignition source to check for leaks. If gas
odors are detected, shut off the gas supply to the appliance at the main shut-off
valve and immediately contact the local gas company or an authorized service agen-
cy for service.
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 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.
