The pilot fl ame should be steady, not lifting
or fl oating. Flame should be blue in color with
traces of orange at the outer edge.
The top 3/8" (10 mm) at the pilot generator
(thermopile) and the top 1/8" minimum (tip)
of the quick drop out thermocouple should be
engulfed in the pilot fl ame. The fl ame should
project 1" (25 mm) beyond the hood at all three
ports. See Figure 12 or 13.

tions on Pages 17 & 18.
