Oven Calibration (oven knob adjustment)

Vulcan Endurance and Wolf Challenger XL new Connect-A-Range models are being shipped with an adjustable oven knob
on every standard oven BJWA t-stat control. This knob allows for an oven temperature adjustment (calibration) of +/- 30F
without changing the offset of the BJWA control itself. To adjust oven temperature use the following steps:

1) Set oven to most commonly used temperature in the specific application (between 300-450F).

2) Place accurate temperature sensing device into the center of the oven and allow the oven temperature to stabilize.

3) Log knob reading and actual oven temp.

4) Remove knob and turn over to reveal adjustment lock screws.
