GAS OVEN COMPONENTS
INFRARED BURNER ASSEMBLY
This is the Burner located beneath the floor of the oven�
The tubes on the outside of the Burner are used to supply
air to the Burner� You will not see flame in these tubes�
DO NOT ATTEMPT TO LIGHT THIS BURNER MANUALLY!
To visually verify that the Burner is running, look through
the gap next to the Pilot assembly and you should see a
reddish glow over the ceramic Burner elements� This Burner
operates only when the hearth temperature is lower than
the Controller’s Hearth Set Point�
THERMOCOUPLE
A Type K Thermocouple is used to sense the temperature of the oven floor (hearth),
about 1 inch beneath the hearth surface� It is located slightly to the rear of the center
of the oven (behind the IR on an IR equipped oven)� It is embedded in the floor of the
oven, but is easily replaceable� Older 9690 models only are equipped with a second
calibrated Thermocouple for the overtemp module�
SV1 AND SV2 WIRE HARNESSES
These harnesses supply the voltage needed to activate and power the ignition system
on the respective Valves� They also send flame verification voltage from the Valve back
to the Controller�
HEAT SHIELD
The Heat Shield (on models FD-6045 and FD-8645) helps the oven retain heat�
A pulley and counterweight system enables the Heat Shield to remain in the open
position to allow easy access for moving product in and out of the oven� A special
high temperature glass is used in the Heat Shield� If the glass becomes broken or
damaged, replace only with glass supplied by Wood Stone�
Pulley/counterweight system
CONTROLLER WIRE HARNESS

Thermocouple wires�
