Installing a New Main Gas Cock
Eachapplianceshouldhaveitsownmanualgascock.
Amanualmaingascockshouldbelocatedinthevicinityoftheunit.
Wherenoneexists,orwhereitssizeorlocationisnotadequate,
contactyourlocalauthorizedinstallerforinstallationorrelocation.

totheactionofliqueedpetroleumgases.Thegaslinesmustbe

Never use an exposed ame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
