Pilot Flame Characteristics

The correct ﬂame will be almost horizontal, blue and will extend past the thermocouple 1/4” (6mm). The ﬂame will surround the thermocouple just below the tip.

On Propane (LP-gas) slight yellow might occur where the pilot ﬂame and the burner ﬂame meet.

Natural gas pilots require adjusting when the inlet pressure is above 5” w.c. (1.25kPa). Remove pilot adjustment cover. Turn adjustment screw clockwise to reduce ﬂame.

Propane (LP-gas) will not require adjusting.

MAIN BURNER FLAME CHARACTERISTICS

There will be a short blue inner ﬂame with a larger, lighter blue secondary ﬂame. The burner ﬂame may have yellow tips when hot. Dust in the combustion air will produce and orange or red ﬂame. Do not mistake the orange or red ﬂame for an improper yellow ﬂame. The ﬂame will be proper if the factory-set pressure and oriﬁce are used. After use, cleaning may be required for the proper ﬂame.

On Propane gas, if a whistling noise (resonation) occurs

a.Screw the air adjustment bolt into the burner throat to eliminate the whistling noise (resonation).

b.Size main burner oriﬁce with a drill bit. For RH-50(C) use #47 drill bit. For RH-65(C) use 2.3mm drill bit.
