ADJUSTMENTS Continued
3. Set the thermostat temperature dial to 500 degrees
F (260 degrees C) and allow the oven temperature
to stabilize. The thermostat must be allowed to
cycle twice before taking a test reading.
4. Check the temperature when the burner just cycles
off after the second cycle, compare the reading of
thermocouple or thermometer with thermostat
setting.
5. If the two do not agree (plus or minus 15 degrees
F (8 degrees C)), carefully remove the thermostat
dial, not disturbing dial settings.
6. Hold calibration plate and loosen the two calibration
screws until the plate can be moved independently
of the control.
7. Turn calibration plate so that the instrument of
thermometer reading is in line with the indicator
mark. Hold plate and tighten screws firmly.
8. Replace dial.
9. NOTE: If the above adjustment is prevented by
the two loosened calibration lock screws being in
contact with the ends of the screw clearance plate to
the proper location, reassembly screws in the other
tapped holes designed for them.
NOTE: NO ATTEMPT TO RECALIBRATE
THE OVEN CONTROL SHOULD BE MADE
WITHIN THE WARRANTY PERIOD IF THE
TEMPERATURE IS WITHIN ± DEGREES
FAHRENHEIT OF THE DIAL SETTING.
RECALIBRATION SHOULD BE MADE IF THE
CONTROL IS OUT MORE THAN ± DEGREES
FAHRENHEIT AND LESS THAN ± DEGREES
FAHRENHEIT. IF THE CONTROL IS OUT MORE
THAN  DEGREES FAHRENHEIT FROM THE
DIAL SETTING, THE CONTROL WILL BE
REPLACED UNDER WARRANTY, (WITHIN
THE WARRANTY PERIOD).
Flame Diverters
Flame diverters distribute the heat evenly below the deck.
They must be in good condition and properly placed in
the burner chamber in order to be effective. Damaged or
improperly installed flame diverters adversely affect the
oven performance. Check them periodically and replace
as needed. Make sure that the “V” shaped diverters are
pushed all the way to the back of the oven as far as they
will go.
OPERATION
Break-In
1. Once the equipment has been installed and tested
by qualified professional personnel, the oven is
ready for operation.
2. Many of the parts used in the oven have a thin
protective oil covering. This oil should be burned
off before the oven is used for the production of
food products. It is normal for the unit to smoke
while burning off excess oil. Washing the deck of
the oven with a damp clean cloth and mild soap
solution will remove some of the protective oil
coating.
3. Select a temperature of 300 degrees F (150
degrees C) and turn the gas cock dial to the ON
position.
4. Allow the oven to warm to 300 degrees F (150
degrees C) and keep it there for FIVE HOURS, or
at least until all smoke and fumes have disappeared.
The smoke and fumes are from moisture in the deck
and insulation and a light coat of oil.
5. Turn the thermostat knob to between 475 degrees
F (250 degrees C). Allow the oven to warm up to
your selected temperature for 1 to 1 ½ hours.
