Make sure external regulator has been installed between propane/

LP supply and heater. See guidelines under Connecting to Gas

Supply, page 14.

PRESSURE TESTING GAS SUPPLY PIPING SYSTEM

Test Pressures In Excess Of 1/2 PSIG

1.Disconnect heater and its individual manual shutoff valve from gas supply piping system. Pressures in excess of 1/2 PSIG will damage heater regulator.

2.Cap off open end of gas pipe where manual shutoff valve was connected.
