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.
23. Using a soap and water solution, check for leaks around
the gas valve/manifold connection and the burner orices.
Repair any leaks before continuing.
24. NOTE: Any other gas-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-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. Adjustments
to this pressure can be made using the high regulator
adjustment screw.
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.
31. For hybrid models, control board switches may need to be
re-set to single stage operation depending on installers
preference of operation.
32. Reinstall the access panels.
33. Turn on the gas and electrical supply.
34. Reset all other appliances so they function normally.
