WARNING
Do not exceed 600 in−lbs (50 ft−lbs) torque when attaching the gas piping to the gas valve.
Gas supply piping should not allow more than 0.5"W.C. drop in pressure between gas meter and unit. Supply gas pipe must not be smaller than unit gas connection.
Compounds used on gas piping threaded joints should be resistant to action of liquefied petroleum gases.
C−Testing Gas Piping
IMPORTANT
In case emergency shutdown is required, turn off the main
