A 1/8” N.P.T. plugged tap, accessible for a test gauge connection, must be installed in the main gas supply line immediately upstream of each dryer.
IMPORTANT: Pipe joint compounds that resist the action of natural and liquid propane (L.P.) gases must be used.
WARNING: NEVER TEST FOR GAS LEAKS WITH A FLAME!!!
IMPORTANT: The dryer and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).
NOTE: The dryer must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).
