COMPONENT FUNCTION
Control Valves, Top Burners
Brass control valves are used by the operator to
turn on/adjust the gas supply to the burners.
Control Valve, Oven Gas Supply Shut-off
The oven gas shut-off valve turns the gas to the
oven on or off.
Oven Door Switch
(Convection models only)
The door switch is located under the oven control panel.
When the oven door opens, the switch opens the circuit
shutting off the fan motor. If door plunger switch has
failed, the AUTO/MANUAL switch will not shut off the fan.
Ignition Module
(Convection models only)
The ignition module controls and supplies high
voltage to the oven pilot igniter.
Manifold
The gas supply manifold is located behind the top
section burner knobs. The burner control valves
are attached to the manifold, which is a large pipe
full of gas under pressure.
Motor, Convection Oven
The single-phase convection oven motor circulates
oven heated air. The motor electrical circuit is routed
through door switch and through the blower AUTO/
MANUAL switch. The door closes the door switch and
allows voltage to flow from the door switch to the motor.
The motor should operate with the door open when the
blower switch is in the manual position.
Orifice
Each burner is supplied with gas through an
orifice.
Pressure Regulator
The pressure regulator regulates the incoming supply
pressure to keep the pressure of gas in the range at
a constant level (5" WC nat., 10" WC propane).
Oven Pilot and Control Valve Assembly
The safety control valve senses the presence of
the pilot light via the thermocouple and opens the
gas valve to the oven only when the pilot light is lit.
Thermocouple/Safety Control Valve
The thermocouple on the pilot safety valve
prevents gas from being sent to the oven burners
unless the pilot light is on.
Pilot Valve Assembly, Top Burners
Adjustable valves in the gas manifold control
the flow of gas to the individual pilot lights for
the top burners.
Oven Thermostat
The thermostat regulates oven temperature by
regulating the gas flow to the oven as required to
maintain oven temperature.
Oven Timer (Optional)
The oven timer control provides an audible alert
after a specific time interval.
Junction Box
(Convection models only)
The junction box is located at the rear of the range
and is the connection point for electrical wires that
control the convection fan motor.
Power Cord
(Convection models only)
The power cord connects the range to the power
source. The convection oven will not operate
unless connected to an electrical power supply.
Conventional ovens and top burners do not require
electrical power to operate.
