type required for appliance. Gas supply line must at least be the equivalent of 3/4” iron pipe. Verify that gas supply pressure
is between 5”and 11”wc. Leak test all joints and fittings with soapy water; do not leak test using an open flame. Before
proceeding to next step, smell around the appliance area for gas. Be sure to smell next to the floor because some gas is
heavier and will settle on the floor. IF YOU SMELL GAS, FOLLOW GAS SAFETY PROCEDURES OF THIS MANUAL AND

APPLIANCE-OWNER’S EMERGENCY SHUT-DOWN PROCEDURE.

Gas Startup

This appliance is equipped with an ignitor which lights the burners automatically. Do not try to light the burner by hand.

Turn burner on. Ensure gas VALVE control switch is set to “ON.” Turn on electric power to appliance. Turn on control and

adjust Set Point to desired temperature. Press fan button to turn burner on. Verify ignition from sight port on burner.

Check O2 (oxygen) and CO (monoxide) levels. To do this, turn conveyor belt off at control and place flue gas analyzer tube
on belt with end of tube inside oven.

Calibrate Oven Temperature, if required. Insert a thermocouple inside the cook chamber and place on the conveyor belt.
Route the probe wire out of the loading door opening and adjust the oven set point to 350oF. Allow the oven to reach the
set point and stabilize for at least 90 minutes. If the thermocouple reading and the controller actual temperature differ by
more than a couple degrees, the control must be calibrated. To begin, make a note of the temperature difference between
the thermocouple and the controller actual temperature, then turn the control power button off an d hold the fan off/on
button for 3 seconds until a value appears in the set point display. Use the set point up or down arrow to add or subtract the
difference in temperature. (EXAMPLE: If the thermocouple is 10o higher than the actual temperature, add 10. If the
thermocouple is 10o lower than the actual temperature, subtract 10.) Turn the control button on and re-check the
thermocouple against the controller actual temperature. Repeat this procedure until the two temperatures match.

Conveyor Inspection

Verify belt speed. Use Conveyor Speed up or down arrow to set time of 05m:00s. Place object on belt at entrance of cook

chamber and, using a watch with a second hand, time how long it takes the object to travel to exit of cook chamber. If time
