ADJUSTMENTS Continued
5. Hold the shaft steady and with a small flat screw driver
turn the calibration screw located inside the shaft
clockwise to decrease temperature or anti-clockwise to
increase temperature. Note: Each 1/4 turn of the screw
will create a change of approximately 25°F (14°C).
6. Replace the thermostat dial and repeat steps 1 through 3
to verify that a correct adjustment has been made.
Broilers
IMPORTANT: The flue must be installed prior to start-up.
Pilot Burner Adjustment
Each burner in the broiler is equipped with a pilot. The
burner pilot is ignited by the piezo ignitor located behind the
front door.
The pilot has been adjusted at the factory; however, it may
require adjustment once installed. The pilot adjusting valve is
located under each burner valve. Open the bottom door and
use a long thin straight blade screwdriver to adjust the valve.
Refer to Flame Size Chart.
Burner Operation
The burner will light automatically from the pilot. Turn the
valve to the full “ON” position. Once the flame has ignited,
adjust the valve to the desired setting.
HI-LO Valve Adjustment
Broilers are equipped with HI-LO valves which require a low
flame setting. To adjust, proceed as follows:
1. Burner must be cold.
2. Be sure pilot flames are lit and adjusted.
3. Turn dial to “LO” position, then remove dial.
4. With a screwdriver, turn the small adjusting screw inside
the valve stem and adjust to obtain the low cooking
temperature desired, maintaining a stable flame covering
the entire burner (minimum 3/16” (5 mm) long flame).
5. Replace dial and turn to “OFF” position.
