GENERAL
CAUTION: Operating, testing, and servicing should only be
performed by qualified personnel.
When any difficulty arises always check that the unit has been connected to the gas supply type
and voltage for which it was supplied. This can be done by examining the serial plate on the
lower right side of the unit. It will list the gas type and voltage for which the unit was
manufactured.
Wiring diagrams for the unit are located in a small envelope affixed to the rear side of the front
control panel.

MANIFOLD PRESSURE
Natural Gas - 4 inches W.C.
LP Gas - 10 inches W.C.
GAS PRESSURE REGULATOR
The gas pressure regulator is an integral part of the combination gas control located just behind
the lower front access door. The pressure regulator adjustment is on the lower right side of the
gas control. The large slotted cap must be removed to access the adjustment screw.
ADJUSTMENTS
To check the manifold pressure a pressure gauge (manometer) must be connected to the 1/8"
NPT pressure tap on the gas manifold. With the gas off, connect your pressure indicating
instrument to the manifold with a fitting appropriate for your instrument.
Turn the unit on; with main burners on, read the manifold pressure. The pressure should be 4
inches water column (W.C.) (
"
) .2 inches W.C. for natural gas or 10 inches W.C. for propane
gas. Adjust the pressure regulator to obtain the appropriate pressure. Check serial plate on
lower right side of unit to confirm exact gas type and manifold pressure for your unit.
