GAS CONVERSION
General
All ovens are equipped with double coaxial (universal)
orifices and with a convertible appliance pressure
regulator. The oven model number plate states which gas
it was adjusted for at the factory. NOTE: Oven model
number plate is located on bottom of control panel lower
trim. To convert the unit to either Natural gas or LP gas
will require adjustment of the orifice hood and air shutter
on the burner and adjustment of the appliance pressure
regulator converter cap.
Inlet pressure to the appliance pressure regulator should
be as follows for both operation and checking of appliance
pressure regulator setting:
INLET PRESSURE IN

Appliance Pressure Regulator
Conversion
The ovens appliance pressure regulator must be set to
match the type of gas supply used. If converting from
natural gas to LP gas, the appliance pressure regulator
must be converted to regulate LP gas. If converting from
LP gas to natural gas, the appliance pressure regulator
must be converted to regulate natural gas. The type of
gas for which the regulator is set for will be visible on the
plastic plunger which is snapped on to the bottom of the
brass hex nut (either Nat. or LP).
TO CONVERT THE APPLIANCE PRESSURE
REGULATOR FROM ONE GAS TO ANOTHER, DO THE
FOLLOWING:
1. Remove the brass hex nut from the regulator.
2. Unsnap the plastic plunger from the bottom of the brass
hex nut, and turn the plunger over. The gas type you
are converting to MUST be visible on lower side of
plunger.
3. Snap plunger back in to bottom of the brass hex nut,
and install brass hex nut back into regulator. (See
figure 3).
Checking Manifold Gas Pressure
BUILT-IN OVENS:
On built-in ovens, remove 1/8 inch pipe plug from side of
gas pressure regulator, install 1/8
²
“B” valve, 1/8 inch
piece of pipe, connect manometer, make sure main
burner is on to obtain accurate pressure check.
Be sure the gas supply (house piping) pressure is at least
one inch (1
²
) above specified range manifold pressure.
The gas supply pressure should never be over fourteen
inches (14
²
) water column.
Checking Pressure Of House Piping
System
The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 lbs./sq. in. (14 in. W.C.).
The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 lbs./sq.
in. (14 in. W.C.).
