2. GAS HOOK UP
An adequate gas supply is imperative. Undersized lines or low-pressures will restrict the
volume of gas required for satisfactory performance. A steady supply pressure between 7’’ and
8’’ w.c. for natural gas and 11’’ to 12” w.c. for propane gas is required. With all gas appliances
operating simultaneously, the manifold pressure on all gas appliances should not show any
appreciable drop. Fluctuations of more than 25% on natural and 10% on propane gas will
create pilot problems, and affect burner-operating characteristics. Contact your gas company
for correct supply line sizes. After connection, all newly installed equipment should be checked
for correct gas pressure by a certified gas serviceman. The unit should be connected ONLY to
the type of gas for which it is equipped. Check the type of gas on serial plate.
A. Attach regulator supplied with machine to inlet of the gas manifold. Be sure regulator is
connected so that gas flow is in the direction of the arrow on the bottom of the regulator.
Using a regulator other than the one supplied with the unit will void the warranty.
B. The manifold pressure must be maintained at the pressure marked on the serial plate: 4”
w.c. for natural gas and 10” w.c. for propane gas.
C. Use pipe joint compound that is suitable for use with LP gas on all threaded connections.
D. Turn off all burner valves.
E. Turn on gas supply and check all connections for leaks using ONLY a leak checking fluid or
soapy water. NEVER use an open flame to check for gas leaks.
F. Provision must be made for adequate air supply for both appliance and occupants.
G. Keep area in front of unit free from obstructions that could block flow of combustion and
ventilation air.
H. Be certain that adequate clearance is maintained so that air openings in front of unit are not
blocked and any subsequent service can be performed. No such clearance is required on
the sides. Sufficient clearance at rear is required for gas connections, regulator, and any
master shutoff valve(s) installed. Be sure there is no obstruction in front.
