IMPORTANT:
Disconnect the furnace and its individual shutoff valve from the gas sup-
ply piping during any pressure testing of that system at test pressures in excess of 1/2
pound per square inch gauge or isolate the system from the gas supply piping system
by closing its individual manual shutoff valve during any pressure testing of this gas sup-
ply system at pressures equal to or less than 1/2 PSIG.
TO CHECK FOR GAS LEAKS, USE A SOAP AND WATER SOLUTION OR OTHER
APPROVED METHOD. DO NOT USE AN OPEN FLAME.
IMPORTANT:
Check the rating plate to make certain the appliance is equipped to burn
the type of gas supplied. Care should be taken after installation of this equipment that
the gas control valve not be subjected to high gas supply line pressure.
