GAS CONNECTION
1. The Serial and Rating Plate on the unit indicates the type of gas your unit is equipped to burn.
DO NOT connect to any other gas type.
2. A 3/4" NPT line is provided at rear for the connection. The unit is equipped with an internal
pressure regulator which is set at 4" W.C. manifold pressure for Natural Gas and 10" W.C. for
Propane Gas. Use 1/8" pipe tap on the union elbow assembly located in the console for
checking pressure.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of
gas required for satisfactory performance. A steady supply pressure, minimum 6" W.C. for natural
gas and minimum 12" W.C. for propane gas is recommended. With all units operating
simultaneously, the manifold pressure on all units should not show any appreciable drop.
Fluctuations of more than 25% on natural gas and 10% on propane gas will create problems,
affecting burner operation. Contact you gas company for correct supply line sizes.
Purge the supply line to clean out any dust, dirt or other foreign matter before connecting the line
to the unit. Use pipe joint compound which is suitable for use with L.P. on all threaded
connections.
Test pipe connections thoroughly for gas leaks.
USE SOAPY WATER ONLY FOR TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO
CHECK FOR GAS LEAKS.
ALL THE CONNECTIONS MUST BE CHECKED FOR LEAKS, AFTER THE UNIT HAS BEEN PUT IN
OPERATION.
