Gas Conversion
General
All ovens are equipped with double coaxial (universal) orifices and with a convertible appliance pressure regulator. The unit model number plate states which gas it was adjusted for at the factory. 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 | NATURAL | LP |
INCHES OF WATER COLUMN | GAS | GAS |
Minimum | 5 | 11 |
Maximum | 14 | 14 |
off with nut). "IMPORTANT" remove plastic dust cover from cap nut and reinstall on opposite side of cap nut.
Reinstall cap nut to appliance pressure regulator and replace dust cover. "CAUTION" be sure marking for the type of gas to which appliance pressure regulator has just been converted is visible in top of cap nut before replacing plastic dust cover. (See figure 7.)
. Remove cap and forcibly snap out plastic plunger from bottom of cap. Turn plunger over and forcibly snap back in original location (figure 8).
NOTE: PLUNGER MUST SNAP INTO POSITION; THE GAS TYPE YOU ARE CONVERTING TO MUST BE VISIBLE ON LOWER SIDE OF PLUNGER.
Appliance Pressure Regulator Conversion
The unit appliance pressure regulator must be set to match the type 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.
TO CONVERT THE APPLIANCE PRESSURE REGULATOR FROM ONE GAS TO ANOTHER, DO EITHER (1), (2) OR (3) BELOW: YOUR UNIT WILL BE EQUIPPED WITH ONE OF THE THREE APPLIANCE PRESSURE REGULATOR TYPES SHOWN BELOW.
1.Remove the cap, push down and turn
NOTE: THE GAS TYPE YOU ARE CONVERTING TO MUST BE VISIBLE ON THE TOP OF THE INSTALLED APPLIANCE PRESSURE REGULATOR CAP.
2.Remove plastic dust cover from cap nut on top of
appliance pressure regulator. Remove cap nut from appliance pressure regulator (plastic dust cover comes

Checking Manifold Gas Pressure
BUILT-IN OVENS:
On
Be sure the gas supply (house piping) pressure is at least one inch (1 ") above specified range manifold pressure. The gas supply pressure should never be over fourteen inches (14") 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 Ibs./sq. in. (13.8 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 Ibs./sq. in. (13.8 in. W.C.).
