C.  LO-FIRE GAS SUPPLY LINE LOOP

The lo-fire gas supply line loop is a 3/4” line, which is responsible for supplying the burner system with the gas
required during lo-fire operation.

1. Adjustable Orifice - The adjustable orifice found in the lo-fire gas supply line controls the flow of gas to

the burner during lo-fire.

a. Adjustable Orifice Lo-Fire Valve Adjustment:

1) Loosen the locking nut by turning the nut counterclockwise (CCW).

2) Turn the adjustment knob clockwise (CW) to reduce gas flow through the Lo-Fire Gas Loop or
