INSTALLATION INSTRUCTIONS

minutes, no longer. Be sure the liquid completely covers the cap and base portion of the assembly. After 20 minutes, remove burner, cool slightly and rinse thoroughly with cold water. Be sure hands are protected to prevent burns from hot water. Be sure all the solution is completely rinsed off both the inside and outside of the burner. If some stains still remain, rub with a "Dobie" pad.

The burner may then be left to dry at room temperature or be placed in the oven at 170° for 1/2 hour. BE SURE TO

PROTECT YOUR HANDS WHEN REMOVING DRIED BURNERS FORM THE OVEN.

UNIVERSAL GAS ORIFICES

With the exception of the Broiler Burner and Sealed Top Burner, orifices for these models are of the coaxial type. They contain a double coaxial orifice hood and universal pin. The hood orifice is sized for Natural Gas (6 inches water column pressure). The pin orifice is sized for LP Gas (11 inches water column pressure).

The orifice is adjusted for Natural gas as shipped from the factory. It must be adjusted for use on LP gas. This requires that the orifice hood be screwed or turned down approximately two (2) turns onto the pin. The hood should be turned down snug but not tight to the point where it damages or distorts the pin. (See Figure 19.)

When set up for Natural Gas, gas flows around the pin and through the orifice of the hood which is sized for Natural Gas. When the hood is screwed down for LP gas, the gas flow is only through the hollow pin which is sized for LP gas.

OVEN THERMOSTAT KNOB ADJUSTMENT

Models without electronic Range Control (ERC)

Cooking recipes are written to take into consideration that oven thermostats have manufacturing tolerances, and may not provide an average temperature exactly on the thermostat setting. If the temperature average reading is beyond the ±25° tolerance range, a limited adjustment can be made with the adjustable skirt on the knob. The adjusting screw on the thermostat is sealed and no adjust- ment can or should be attempted. The rear of the adjust- able skirt shown here is self-explanatory.

NOTE: These thermostats (Robertshaw) have a cement coating over the adjusting screw. Evidence of attempts to adjust these thermostat nullifies the warranty.

For Thermostat Calibration on models with the Elec- tronic Range Control (ERC), see section on ERC Operating and Testing Procedures.

When making any temperature adjustments, a reliable test instrument should be used to accurately determine the oven temperature.

A reliable test instrument of the thermocouple type is preferred which will allow temperature readings with the door closed.

Position the thermocouple clip of the test instrument on the center of the oven rack that is positioned in the center of the oven cavity. The thermocouple of the test instrument should be "weighted" or "loaded" in order to represent more closely the average cooking temperature of the oven versus the on-off cycling of the thermostat with the full rate gas valve. The procedure for loading a thermocouple is illustrated in Figure 20.

Figure 32 - "Loading" A Thermocouple

An 8 1/2 x 11-inch piece of aluminum foil should be folded five (5) times, doubling the thickness with each fold. After the fifth fold, place the thermocouple in the center of the aluminum piece as shown and fold once more. Finally, fold the sides so the foil clings to the thermocouple. The loaded thermocouple will then provide temperature readings on the thermometer that more closely resemble the mean or average temperature of the oven as it cycles on and off above and below the temperature setting.

With all the controls properly set for "Bake", turn the oven thermostat to 350°.
