OPERATION Continued
Convection Ovens
The forced air range oven consists of a food preparation
chamber completely sealed from the combustion area.
This eliminates the possibility of contamination from fl ue
products and permits an effi
cient method of circulating the
heated air within the cooking chamber.
During the cooking process in a conventional oven, a vapor
barrier and a layer of “cool” air covers the exposed area of
the product. In a forced air oven, the fan pushes the heated
air over and around the product, sweeping away the vapor
barrier and cool air, permitting faster heat penetration. This
action permits the use of lower temperatures and shorter
cooking times.
The rule of thumb for determining the cooking temperature
is to reduce the set temperature by approximately
80°F, (28°C), from that which you would set in a conventional
oven. The product should be checked at a point midway in
the time required in a conventional oven.
Lighting
1. Lower front kick panel below oven door.
2. Push and hold in oven thermostat control valve knob
(fi gure 1) and turn it counter clockwise to the ignition
position “ ”.
3. While holding knob fully in depress the red igniter button
and observe that the pilot fl ame is lit. If it does not light,
repeatedly depress the igniter button until it does.
Note: On ranges equipped with electric spark igniters, press
the igniter button and check if the pilot lights. Should burner
ignition fail within 4 seconds, turn the burner valve off and
repeat steps 1 through 2. If ignition continues to fail, consult
the factory authorized service agency.
4. When the pilot is lit, continue to hold the valve knob fully
in for 15 seconds, then release it. If the pilot goes out, wait
for fi ve (5) minutes, then repeat steps 2 to 4.
Start Up
1. Set the power switch to the “COOK” position.
2. Turn the thermostat to the desired setting.
Cool down
1. Turn the oven valve knob to the “ ” position this will
prevent the main oven burner from cycling on. (fi gure 1).
2. Turn the thermostat to its lowest setting.
3. Open the oven door.
Warning: Use caution when opening the oven door while it
is in use. Hot air or steam may cause injury.
4. Set the power switch to the “COOL DOWN” position.
5. Once the oven has cooled turn the power switch to off
and close the oven door.
Shut Down
1. If pilot shut down is required push in oven thermostat
knob turn to “ ” symbol. The system will disengage with
in 60 seconds.
2. Power switch should be in the off position.
Operating Suggestions
The motor in your range convection oven is maintenance
free since it is constructed with self-lubricating sealed ball
bearings. It is designed to provide durable service when
treated with ordinary care. We have a few suggestions to
follow for the care of your motor.
A. When the motor is operating, it cools itself internally by
air entering the rear of the motor case, provided proper
clearance has been allowed.
B. Since the blower wheel is in the oven cavity it is at the
same temperature as the oven. If the motor is stopped
while the oven is hot, the heat from the blower wheel is
conducted down the shaft and into the armature of the
motor. This action could shorten motor life.
C. We recommend, at the end of the bake or roasting
period, when the oven will be idle for any period of time
or before shutting down completely, that the doors
be left open, and by use of the cool-down position on
the fan switch, the fan continues to run for at least 20
minutes. The “FAN” should never be turned “OFF” when
the oven section is in use.
