The heater regulator controls the burner pressure which should be checked at the pressure test point
located on the front of the main control and is accessible by removing the control panel on the right
side of the heater.
The pressure should be checked with the heater burning and the control set to high (HI).
The pressure regulator is preset and locked to avoid tampering. If the pressure is not as specified
in Product Specifications (Page 5), contact your dealer and replace the regulator.
