Unit Adjustments

Wall Oven Adjustment

ELECTRIC IGNITION - BAKE BURNER WITH ELECTRIC GLOW BAR

a.The bake burner is equipped with an electric control system as well as an electric oven burner ignitor (figure 2). This control system requires NO adjustment. To operate, turn thermostat knob to any temperature setting or to broil. Current will flow to the ignitor. It will “glow” similar to a light bulb. (This glow may be reflected into the oven through the openings in the oven bottom). When the ignitor has reached a temperature sufficient to ignite gas, the electrically controlled oven valve will open and flame will appear at the oven burner. There is a time lapse from 30 to 45 seconds after the thermostat is turned ON before flame appears at the oven burner. When the oven has reached the dial setting, the glowing ignitor will go OFF. The burner flame will go “out” in 20 to 30 seconds after the ignitor goes “OFF”. To maintain any given oven temperature this cycle will continue as long as the dial is at the given temperature. Figure 3 is an illustration of a typical range.

FIGURE 2

b.In case servicing should become necessary, a manual gas valve to shut off the gas to the oven burner is supplied between the gas regulator and the oven burner valve. It is located at the front of the oven bottom or on right rear of gas regulator. See figure 3.

c.The oven CANNOT be used during periods of power outage. In case of power failure, turn the thermostat to the OFF position.

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.)

3.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 counter-clockwise. Turn the cap over and reinstall (figure 6).

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 built-in ovens, remove 1/8 inch pipe plug from front or side of gas pressure regulator, install 1/8 “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 ) 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 lbs./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 lbs./sq. in. (13.8 in. W.C.).
