Installation and Operation of Electric Convection Oven
thermostat related problems could be attributed to their
being out of adjustment (calibration).Athermostat that is
out of calibration may cause unsatisfactory cooking results
such as uneven baking, prolonged cooking times, etc. If
you are experiencing uneven cooking, it may be a result
of excessive cooking temperatures. Refer to the cooking
chart provided in Operating Instructions Section C.
This thermostat is a
direct-acting(opens

E. CLEANING OF THE OVENS
The stainless steel on your oven can be kept clean with
a good stainless steel cleaner, many of which are on
themarket.The painted surfaces should be wiped clean
regularly witha MILD detergent. Moisten a clothand
wipe down the oven while it is COLD. Wiping down an
oven while it is hot will cause streaking and otherwise
unsatisfactory results. Once the oven is clean it can
be wiped down withlight oil.
•
Turn the oven on by turning the Power Switchto
the
ON position.
•
Open the doors and place a thermocouple in the
center of the middle oven rack.Areliable mercury-

•
Turn the thermostat dial to 350°F (177°C). Allow
the
oven to preheat 1/2 hour.
•
When the indicator light goes out,the thermostat
has
been
satis
fied.
Check
the
pyrometer
or
thermometer
to determine the internal oven temperature.
•
If the
reading on the pyrometer(or
thermometer) is
less
than10°F different from the setting of the
thermostat,
no adjustment is needed. If this reading is
more than
10°F, proceed with calibration procedure.
Porcelain oven interiors should be cleaned regularly
using a degreasing agent. For heavier deposits a
commercial oven cleaner such as Dow Oven Cleaner,
Easy-Off, or Mr. Muscle can be used. Care must be
taken to prevent these alkaline-type cleaners from
coming in contact withany aluminized steel surfaces
in the oven, including the blower wheel.
To Calibrate the Ovens
•
Remove the thermostat knob by loosening the
setscrew and pull the knob forward. Take care not
to rotate the thermostat stem, which will change
the setting.
The blower wheel, racks and rack supports can be
removedandsoakedinasolutionofammoniaandwater.
•
With a very small screwdriver,turn the screw located
in the bottom of the hollow of the stem clockwise
to lower the temperature or counterclockwise to
raise the temperature. DO NOT allow the stem of
the thermostat to rotate as you turn the screw.
Make certain that all parts are thoroughly rinsed before
returning to use.
•
Open the door and turn the POWER SWITCH to the
COOL DOWN position. This will allow the oven fan
To come on without the burners and cool off the oven.
Allow the oven to cool to about 250°F (120°C).
•
•
Return the POWER WITCH to the ON position and
Repeat the previous steps until the oven thermostat
and the pyrometer (thermometer) reading agree.
Replace the knob and tighten the setscrews.
NOTICE:Maximum turn of screw“A” is1-1/2turns–
clockwise or counter-clockwise.
