OPERATION AND SERVICE PROCEDURES

TO AVOID THE RISK OF ELECTRICAL SHOCK, PERSONAL INJURY OR DEATH DISCONNECT POWER BEFORE SERVICING, UNLESS TESTING REQUIRES IT.

The "HI" position provides a flame which will bring water to a full boil quickly. This is the "full on" position of the valve.

If the burner flame is turned down, an audible "click" can be heard as the valve reaches the "MEDIUM" position. This flame is sufficient to keep water boiling in a covered pan.

When the flame is turned down still lower, a second "click" can be heard. This is a very low or "Keep Warm" flame setting which is the "LO" position on the valve. The low flame provides a warming heat to keep food which is already cooked ready to serve.

The Tri-Set valves are equipped with metered, fixed orifices and the low setting cannot be adjusted. As there are air shutters, the burner flames can be adjusted in accordance with the Adjustment and Calibration Instruc- tions of this Manual.

The HI-LOW valves on other models are similar but without the "click" stops.

TOP BURNER

The top burners consist of a burner and intergral cap, a flash tube and support, a gas delivery tube including venturi and an adjustment air shutter. These burners are designed for trouble free operation with a minimum of parts.

INDICATOR LIGHT TESTING

If the oven (bake, broil, clean) operates normally but the indicator lights do not glow, check for voltage at the indicator light terminals. If voltage is present at the indicator terminals and the indicator does not glow, replace the indicator light. If no voltage is present at the indicator terminals, check for loose connectors, broken wiring, or other defective components (thermostat, ignitor, etc.). NOTE: The oven indicator light and the clean indicator light operates on 120 VAC. Use caution when checking for indicator light voltages.

OVEN LIGHT SWITCH

The oven light switch can be tested using the same procedure as the fluorescent light switch.

The fluorescent light components, oven light switch and indicator lights are located behind the backguard glass mounted to the backguard control panel.

The indicator lights, oven light switch, selector switch, and thermostat on RST307, 308, 309 are located behind the control panel.

BURNER CAPS

Models with Sealed Burners

The burner caps on models with sealed burners contain the electrode tip for the spark ignition.

TO CHECK THE BURNER CAP:

1.Turn off power to the unit.

2.Remove burner cap from unit. Attach one of the ohmmeter leads (RX1 scale) to the electrode termi- nal. Attach the other lead to the tip of the electrode. Continuity (low ohms) should be indicated. If continu- ity is indicated, remove one (1) lead and attach lead to the burner cap. Infinite ohms (open) should be indicated.
