NOTE: CALIBRATION IS EXCLUDED FROM FWE WARRANTY.
Thermostats on all units are
calibrated at the factory prior to shipping. Due to conditions in transit, beyond our control, occasionally units
will need to be re-calibrated prior to use. This is a simple procedure for which instructions are given above.

Heating element will either function or not function. Only a slight warmth indicates a problem
