Standard Ovens
1. Push in the main/pilot gas valve and turn it counter-
clockwise to the IGNITION position.
2. Lower the front kick panel.
3. Holding the oven gas valve fully in, press the red piezo
igniter button several times.
4. When the pilot burner is lit, continue holding down the
oven gas valve for 20 seconds, then release it. If the pilot
goes out, wait for five minutes and try again.
5. When the pilot light is established, push the gas valve
in again and turn it counter-clockwise to the full
ON position, then set the thermostat to the desired
temperature.
Shut Down:
1. Turn all valves to the OFF position and the safety device
will disengage within 60 seconds.
2. If the unit is to be shut down for an extended time, close
the in-line gas valve.
RC Convection Ovens
Power failure:
In the event of an electrical power failure, do
not operate this oven. It is gas operated, but has electrical
features, motor and door switches. A wiring diagram is
attached to the rear of the appliance.
Start Up:
1. Turn the power switch to the COOK position.
2. Turn the gas oven valve to ON.
3. Turn the thermostat to the designed setting.
Cool Down:
1. Turn the thermostat and oven valve OFF.
2. Open the oven door.
3. Turn the power switch to the COOK DOWN position.
Shut Down:
1. Turn the thermostat OFF.
OPERATION continued
2. Return the power switch to OFF.
3. Turn the oven valve OFF.
Motor Care:
The motor on a convection oven is equipped with sealed,
self-lubricating ball bearings and is maintenance free. It will
give durable service when treated with ordinary care. Here
are some operating notes.
1. When the motor is operating, it is cooled internally by
air entering the rear of the motor case, provided proper
clearance has been allowed. Ensure that rear of range has
minimum 25 mm clearance around perimeter.
2. Because 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, heat from the blower wheel is
conducted by the shaft to the motor armature. This can
dramatically shorten motor life.
3. It is recommended that, at the end of the bake or roasting
period when the oven may be idle or ready for shut-
down the oven door be left open. Use the COOL-DOWN
position on the fan switch, which keeps the fan operating
for at least 20 minutes.
CAUTION: Never turn the fan OFF when the oven is HOT.
Char-Broiler (MST Models)
1. Raise or remove the cooking grates. Every group of two
burners has one pilot centrally located between them.
2. Push in the gas valve and turn it counter-clockwise to the
Ignition position.
3. Holding the oven gas valve fully in, depress the red piezo
igniter button behind the lower drop-down panel.
4. When the igniter is lit, continue holding down the oven
gas valve for 20 seconds, then release it. If the pilot goes
out, wait for five minutes and try again.
5. When the pilot light is established, push the gas valve
in again and turn it counter-clockwise to the full
ON position, then set the thermostat to the desired
temperature.
