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).
