In areas where water quality is poor or not qualified, inspection and cleaning may be required to assure
trouble-free operation. Hard water deposits must be removed to prevent corrosion and leaking. Checking
at more frequent intervals may be required to prevent scale buildup. See page 6-13 for information about
removing scale deposits using AERCO HydroSkrub scale remover.
6.3 FLAME DETECTOR
The flame detector (part no. GM-123428) is located in the body of the burner (see Fig. 6.1). The flame
detector may be HOT. Allow the unit to cool sufficiently before removing the flame detector.
To inspect or replace the flame detector:
1. Set the
ON/OFF switch on the control panel, to the OFF position and disconnect AC power from the
unit.
