ADJUSTMENT OF BURNER FLAME
The burners are adjusted at the factory. If necessary to adjust the burner flames, do the following for each burner:
1. Turn the burner’s control knob to the full ON position.
2. If the appliance was cold, wait 5 minutes before adjusting the burner flame.
3. Loosen the set screw that holds the sheet-metal air shutter in place.
4. If the burner flame is blowing or lifting off the burner ports, close the air shutter until a stable flame is obtained. If
the flame is yellow-tipping, open the air shutter until a stable blue flame is obtained (a small amount of yellow-tipping is
normal when using propane gas).
5. Tighten the set screw that holds the sheet-metal air shutter in place.
6. Repeat Steps 1 through 5 for each burner.
When adjusting the burners of griddle models, note that over-gassed burners DO NOT heat griddles as efficiently as
those that are properly adjusted and also create “hot spots” on the griddle surface. Floating and unstable burner and pilot
flames will result when solid tops are lowered into position because the rear openings of the burner compartment are not
adequate to vent the enormous flue products generated by over-gassed burners. The “unburned” gas will ignite at the
rear and burn in this section and even up inside the backguard or shelf venting system, causing structural members in
this area to deteriorate. Also, some of these hot flue products will vent forward into the manifold compartment resulting in
problems with valves and thermostats due to overheating. AGAIN, over-rated burners waste energy and cause service
problems.
ADJUSTMENT OF GRIDDLE THERMOSTATS
Each burner’s control knob operates a snap-action thermostatic valve that was adjusted at the factory. If the griddle
surface temperature is different from the thermostat dial setting, adjust the valve using the following procedure:
1. Turn all the control knobs to the 300°F.
2. Wait 30 minutes (or 1 hour if the griddle was cold).
3. Place a reliable thermometer or test-instrument thermocouple (able to register 300°F) halfway back from the front to
the back of the griddle and directly over a burner (in line with the burner’s control knob, see Figure 9 below). Check the
temperature over each burner every five minutes until the temperature over each burner stabilizes and does not change
by more than 30°F between two consecutive measurements.
4. If the average temperature over any burner is not within 30°F of the knob setting (300°F), adjust the corresponding
thermostatic valve. To do so, remove the knobs and control panel, adjust the calibration screw on the thermostatic valve
(see Figure 9), replace the knobs and control panel, then repeat Step 3.
