Burner Flame Check
(Replaces pg. 23 in instruction manual.)
These models are equipped with self-adjusting air mixture and do not have an
adjustable air shutter (See Figure 9). At periodic intervals a visual check of the
main burner and pilot flames should be made to determine if they are burning
properly. The main burner flame should light smoothly from the pilot.
