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, 3
rd
row from the
outside, 3
rd
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.
