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/
MANUALswitch.Thedoorclosesthedoorswitchand
allowsvoltagetoflowfromthedoorswitchtothemotor.
Themotorshouldoperatewiththedooropenwhenthe
blower switch is in the manual position.
Orifice
Each burner is supplied with gas through an
orifice.
Pressure Regulator
Thepressureregulatorregulatestheincomingsupply
pressuretokeepthepressureofgasintherangeat
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
gasvalve totheovenonlywhenthepilotlightislit.
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)
Thejunctionboxislocatedattherearoftherange
andistheconnectionpointforelectricalwiresthat
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.

ELECTRICAL LOCKOUT/
TAGOUT PROCEDURE
WARNING
BEFORE PERFORMING ANY SERVICE THAT
INVOLVES ELECTRICAL CONNECTION OR
DISCONNECTION AND/OR EXPOSURE TO
ELECTRICAL COMPONENTS, ALWAYS
PERFORM THE ELECTRICAL LOCKOUT/
TAGOUT PROCEDURE. DISCONNECT ALL
CIRCUITS. FAILURE TO COMPLY CAN CAUSE
PROPERTY DAMAGE, INJURY OR DEATH.
The Electrical LOCKOUT/TAGOUT Procedure is
used to protect personnel working on an electrical
equipment. Before performing any maintenance
or service that requires exposure to electrical
components, follow these steps:
1. In electrical box, place equipment circuit
breaker into OFF position.
2. Place a lock or other equipment on electrical
box cover to prevent someone from placing
circuit breaker ON.
3. Place a tag on electrical box cover to indicate
that equipment has been disconnected for
service and power should not be restored until
tag is removed by maintenance personnel.
4. Disconnect equipment power cord from
electrical outlet.
5. Place a tag on the cord to indicate that
equipment has been disconnected for service
and power should not be restored until tag is
removed by maintenance personnel.
GAS LOCKOUT/TAGOUT
PROCEDURE
WARNING
BEFORE PERFORMING ANY SERVICE
THAT INVOLVES GAS CONNECTION OR
DISCONNECTION AND/OR EXPOSURE TO
GAS, ALWAYS FOLLOW THE GAS LOCKOUT/
TAGOUT PROCEDURE. FAILURE TO COMPLY
CAN CAUSE PROPERTY DAMAGE, INJURY
OR DEATH.
The Gas LOCKOUT/TAGOUT Procedure is used to
protect personnel working on a gas equipment.
Before performing any maintenance or service that
requires gas disconnections, follow these steps:
1. Locate the gas shutoff valve or inlet.
2. Place the valve in the OFF position.
3. Place a tag on the valve indicating that service
is being performed on equipment and the gas
must remain off until service is complete.
4. Place a locking device on the gas valve or
inlet, preventing connection until the lock is
removed.
5. On the equipment, make sure all flame sources
are extinguished and/or removed.
6. Bleed residual gas from the equipment inlet
line and allow time for the gas to dissipate
before beginning service on the equipment.
Gas Leak Test
WARNING
ALL GAS JOINTS DISTURBED DURING
SERVICE MUST BE CHECKED FOR LEAKS.
DO NOT USE AN OPEN FLAME. USE A
HAZARDOUS GAS TESTER OR A SOAP AND
WATER SOLUTION. BUBBLES INDICATE A
GAS LEAK. FAILURE TO COMPLY CAN CAUSE
PROPERTY DAMAGE, INJURY OR DEATH.
WARNING
IF A GAS LEAK IS DETECTED, DO NOT
OPERATE THIS OR ANY OTHER EQUIPMENT
UNTIL THE LEAK HAS BEEN PROPERLY
REPAIRED. FAILURE TO COMPLY CAN CAUSE
PROPERTY DAMAGE, INJURY OR DEATH.
After completing service on any gas equipment,
all gas joints disturbed during service must be
checked for leaks. DO NOT USE AN OPEN
FLAME. Use a hazardous gas tester or use a soap
and water solution as follows:
1. Apply a soap and water solution to gas joint
and check for bubbles.
2. If bubbles are present, the joint is leaking and
must be repaired before using the equipment.
