Calibration Procedure for Temperature and Cook Time on the Thermoglaze Model TG50
Turn off power to the TG50 before removing any access covers. This procedure should be performed only by qualified service technicians. Remove the electrical box cover on the oven to access the temperature and speed control adjustment potentiometers. The following is a
photo of the location of the adjustment potentiometers for the temperature and cooking time for the Belshaw TG50 Thermoglaze.

Speed control/cook time adjustment:
Turn on the oven and allow it to heat for 30 minutes.
Put a glaze screen on the conveyor chains that run through the oven. With the oven in operation, time the leading edge of the screen as it enters the oven until the leading edge just leaves the exit end of the oven. Adjust the potentiometer until the desired time/speed is found. To increase the cook time, turn the potentiometer clockwise. To decrease the cook time, turn the potentiometer counterclockwise. The factory setting for cook time for the TG50 is 1 ½ minutes.
Temperature Adjustment:
Measure the temperature from the lower baffle on the exit end of the oven. Place a thermocouple in the hole located on the baffle, 3rd row from the outside, 3rd hole from the back side of the oven. Note: The back side of the oven has a fan motor extended from it. Adjust the temperature by rotating the potentiometer located to the right of the speed control, clockwise increases the temperature, and counterclockwise decreases the temperature. The factory setting is 400º F.
