Pilot Flame Adjustment

{0 Comments}

The pilot flame must be adjusted for proper color and size. Appliance manufacturers refer to this procedure as pilot flame adjustment or pilot gas adjustment.

The appliance manufacturer will provide instructions for making pilot flame adjustments. On combination gas valves, this involves the removal of a pilot adjustment cap and turning the adjustment screw until the desired flame characteristics are obtained. The best pilot flame is a steady, nonblowing blue flame that envelops the upper 3?8 to 1?2 inch of the thermocouple or generator (see Figure 5-62).
