4. FREQUENCY OF OPERATOR CHECKS

Intermittent use.
Appliances that are used seasonally should be checked before shutdown and again before the next use.
Dusty, wet or corrosive environment.
Since these environments can cause the gas control to deteriorate more rapidly, the system should be checked
more often. The gas control should be replaced if:
A. It does not perform properly on checkout or trouble shooting.
B. The gas control knob Is hard to turn or push down, or it fails to pop back up when released.
Below in chart form are various symptoms of a malfunctioning system, possible defects that will cause these
symptoms and suggested corrective measures. The chart assumes that the proper gas pressure is available to the
heater and that the lighting procedure is as stated on the plate attached to the heater.
