The pilot flame should be steady, not lifting or
floating. 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" min (tip) of the quick
drop out thermocouple should be engulfed in the
pilot flame. The flame should project 1" (25 mm)
beyond the hood at all three ports (
Figure 9 - SIT,
Figure 10 - Honeywell ).
To light the burner, refer to the lighting in-
structions on
pages 12 and 13 for Honeywell
and SIT millivolt gas valves).
