THERMOSTAT ADJUSTMENT OVEN:
The calibration of the thermostat should not be changed until sufficient experience with cooking results have definitely proved that the
thermostat is not maintaining proper oven temperatures. Before any recalibration is attempted, the oven temperature should be checked
by the following procedure:
1.
The oven must be empty of all trays or pans.
2. Place a pyrometer thermocouple or a reliable mercury oven-type thermometer at the center of the middle rack.
4. Set the dial at 375° F.
5.
The red "Cooking Light will go out when the thermostat turns off the burners.
6.
Allow three such cycles for the temperature to stabilize.
7. Read the pyrometer or thermostat immediately after the light goes out for the third time and again immediately after it
comes on the next time.
8. If the average of these readings and the dial setting vary by more than 15°, recalibrate by following the instructions
outlined below:
TO RECALIBRATE:
NOTE: Recalibration should be attempted only by a
1. Remove knob from dial shaft (Item "B") from
figure 2.
2. Turn screw (Item "A") in figure 2 clockwise to
decrease and counterdockwise to increase
temperature.
hanges the temperature 35°F.
4. Replace knob on dial shaft.
5. After the calibration is made, set the dial at
375°F and recheck the oven temperature using
the method outlined by steps 1 thru 7 of the
oven temperature checking procedure (as
stated above).
OVEN STANDING PILOT ADJUSTMENT:
The standing oven pilot flame can be adjusted by turning
the adjusting screw on the pilot line valve with a
screwdriver. The pilot line valve is located behind the front
panel below the oven door.
Remove the front panel to gain accessibility. The pilot flame is property adjusted when it is just large enough to maintain a
glowing red color on the flame switch capillary bulb.
OVEN BURNER FLAME ADJUSTMENT:
The oven burner orifice is of the fixed, type sized for the respective gas supply. The burner flame characteristics are
controlled by varying the primary air mixer cap. There should be a clear blue flame with a distinct inner cone at each port.
Excessive primary air can result in "blowing" or the flames leaving the ports. Lack of primary air causes soft or yellow
tipped flame.
THERMOSTAT REMOVAL AND REPLACEMENT:
(GRIDDLE DOESN'T HAVE TO BE REMOVED)
Refer to figures 3 and 4 for instructions below.
1.
Remove thermostat knob(s).
2.
Remove valve panel.
3.
Remove thermostat screw (Item "A") and
orifice bracket screws (Item "B").
4.
Pull thermostat assembly out to side and
remove the burner (Item "C") [this applies for
both sides].
