GAS CONNECTION
WARNING: Do not connect the appliance to the electrical supply
until after the gas connection has been made.
CAUTION: The pipe thread compound used when installing pipes
must be a type that is resistant to the action of liquified petroleum or
propane gases.
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 inch W.C.
for natural gas and minimum 12 inch 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.
WARNING: Never use an open flame to check for gas leaks. Check
all connections for leaks using soapy water before use.
NOTICE: If this equipment is being installed at over 2,000 feet altitude and was
not so specified on order, contact service department. Failure to install with
proper orifice sizing may void the warranty.
