WARNING

NEVER USE AN OPEN FLAME TO CHECK FOR GAS LEAKS.

WARNING

ATTACH THE WARNING LABEL PROVIDED IN THE KIT TO THE GAS

VALVE WHERE IT CAN BE READILY SEEN.

ATTACH THE SMALL, ROUND L.P. LABELS TO THE TOP OF THE

REGULATOR COVER SCREWS.

NOTE: for hybrid models, the control board dip switches

need to be set to 2 stg position to set and verify ﬁ rst stage

heat. (See Installation Instructions supplied with the unit for

dip switch settings)

23. Using a soap and water solution, check for leaks around

the gas valve/manifold connection and the burner oriﬁ ces.

Repair any leaks before continuing.

24. NOTE: Any other gas-ﬁ red equipment should be ON

before any adjustments are made.

After the furnace has been in operation for 15 minutes,

adjust the gas supply pressure (not manifold pressure) to

obtain a range between 11” and 13” W.C. If the gas inlet

pressure falls outside of this range, then make necessary

L.P. service regulator(s) adjustments; check piping size,

etc., and /or consult with L.P. provider.

25. With the furnace operating in its low-ﬁ re (W1) condition, the

manifold pressure should be 6” W.C. ± 0.30”. If necessary,

this pressure can be adjusted using the gas valve low

regulator adjustment screw. Turn clockwise to increase

pressure and counterclockwise to decrease manifold

pressure.

26. Readjust the room thermostat to obtain a second stage

call for heat (W2). The manifold pressure for the W2

condition should be 10” W.C. ± 0.30” W.C. If necessary,

this pressure can be adjusted using the gas valve high

regulator adjustment screw. Turn clockwise to increase

pressure and counterclockwise to decrease manifold

pressure.

27. Using the room thermostat to cycle the unit, observe a

minimum of three (3) smooth ignition cycles.

28. Turn off gas and electrical supply to the furnace, remove

the manometer hose from the pressure tap bosses, and

tighten the inlet and outlet pressure tap screws using the

3/32” Allen wrench.

29. Replace both regulator cover screws on the regulator

sleeve.

30. IMPORTANT NOTE: Apply the conversion label (B14933-

151) provided with the conversion kit. This label must be

attached adjacent to the rating plate.
