INSTALLATION INSTRUCTIONS
ATTENTION INSTALLING PERSONNEL
As a professional installer, you have an obligation to know
the product better than the customer. This includes all safety
precautions and related items.
Prior to actual installation, thoroughly familiarize yourself with
this Instruction Manual. Pay special attention to all safety
warnings. Often during installation or repair, it is possible to
place yourself in a position which is more hazardous than
when the unit is in operation.
Remember, it is your responsibility to install the product safely
and to know it well enough to be able to instruct a customer
in its safe use.
Safety is a matter of common sense...a matter of thinking
before acting. Most dealers have a list of specic good safety
practices...follow them.
The precautions listed in this Installation Manual are intended
as supplemental to existing practices. However, if there is a
direct conict between existing practices and the content of
this manual, the precautions listed here take precedence.

Description Quantity
With the exception of the natural gas burner orices, all of
the fasteners and other components removed to perform
this conversion are to be reused. Any component found to
be damaged due to this conversion must be replaced with
factory authorized replacement parts before this furnace can
be put into o peration.
This furnace is equipped for two-stage heating operation.
The gas valve manifold pressure must be set with rst stage
operating at 6” +/-0.3” W.C. manifold pressure and the second
stage must be set at 10” +/-0.3” W.C. manifold pressure. The
accuracy of these pressures must be checked as shown in
steps 25 and 26 of these instructions.
The gas valve is equipped with a 3-pin polarized plug which
prevents this wiring from being installed incorrectly.
CAUTION
LabeL aLL wires prior to disconnection when servicing
controLs. wiring errors can cause improper and dangerous
operation. verify proper operation after servicing.
NOTE: Do not use power tools for any adjustments on
gas valves.

CARBON MONOXIDE POISONING HAZARD
B10259-216
Carbon monoxide producing devices (such as an automobile, space
heater, gas water heater, etc.) should not be operated in enclosed areas
such as unventilated garages, utility rooms or parking areas because of
the danger of carbon monoxide (CO) poisoning resulting from the exhaust
emissions. If a furnace or air handler is installed in an enclosed area such
as a garage, utility room or parking area and a carbon monoxide producing
device is operated therein, there must be adequate, direct outside
ventilation.
This ventilation is necessary to avoid the danger of CO poisoning which
can occur if a carbon monoxide producing device continues to operate in
the enclosed area. Carbon monoxide emissions can be (re)circulated
throughout the structure if the furnace or air handler is operating in any
mode.
CO can cause serious illness including permanent brain damage or death.
Special Warning for Installation of Furnaces or Air Handling Units in
Enclosed Areas such as Garages, Utility Rooms or Parking Areas

this L.p. (Liquid petroLeum) conversion kit must be
instaLLed by a quaLified service person or agency in
accordance with the manufacturer’s instructions and
aLL appLication codes and requirements of the authority
having jurisdiction. faiLure to foLLow these instructions
eXpLicitLy may cause a fire, eXpLosion or the
production of carbon monoXide (co), which
can cause property damage, personaL
injury or death. the quaLified person performing
this conversion assumes the responsibiLity for the proper
conversion of the appLiance.
Prior to performing this conversion, refer to the National Fuel

CAUTION
if noX screens are present, remove as per instructions in
section “noX screen removaL.”
CAUTION
to prevent unsatisfactory furnace operation, the proper
gas conversion kit must be used for the gas vaLve. use the
white-rodgers spring kit onLy with the white-rodgers
gas vaLve.
NOTE: For low NOx models, see table of contents for
NOx screen section.
1. Turn off the gas supply to the furnace.
2. Turn off the electrical power to the furnace.
3. Remove the furnace control access panel.
4. Check for the presence of NOx screen and remove per
NOx instruction.
5. Separate the gas supply union and remove associated
downstream piping.
6. Always use a backup wrench when removing or replacing
piping to avoid any undue strains or rotation of controls.
7. Remove the wires from the gas valve.
8. Remove the 4 sheet metal screws that fasten the manifold/
gas valve assembly to the burner box.
9. Visually inspect orices for damage and drill size (marked
on face with 1.25mm) before installation. Using the 7/16”
wrench, remove all existing natural gas orices and replace with the appropriate 1.25mm L.P. gas orices contained in this kit. Tighten the orices to prevent gas leaks,
but do not overtighten. Retain the natural gas orices for
future reconversion.
10. Install water manometer using Valve Pressure Check Kit
P/N 0151K00000S included with this kit. Using the included 3/32” hex wrench, rotate outlet pressure tap screw one
revolution counterclockwise. Attach the included 5/16”
hose to the inlet and outlet pressure boss of the valve.
Hose should overlap boss 3/8”. Connect 5/16” side of included connector to the hose on the outlet boss. Connect
1/4” side of the connector to the manometer hose. The
manometer must have a scale range of at least 0” to 20”
of water column.
11. Remove both regulator cover screws.
12. Using a 1/4” at blade screwdriver, remove both regulator
adjustment screws (beneath the cover screws).
13.Remove both Natural Gas regulator springs (color-coded
silver/plain) from regulator sleeves and retain with the
Natural Gas orices for future reconversion.
14. Insert the L.P. regulator springs (provided in the conversion kit and color-coded white) into the regulator sleeves.
15. Replace the High regulator adjustment screw and adjust
approximately 12 turns to the bottom stop.
16. Replace the Low regulator adjustment screw and adjust
approximately 8 turns.
17. Reinstall the manifold/gas valve assembly into the appliance. Rewire the gas valve.
18. Apply a liberal amount of pipe joint compound or pipe
thread tape to the threads and reassemble the piping
previously removed.
WARNING
to prevent the possibiLity of gas Leaks, the pipe joint com-
pound or pipe thread tape must be resistant to L.p. gas.
19. Turn on the gas supply.
20. Using a soap and water solution, check for leaks around
the gas valve/manifold connection.
21. Turn on the electrical supply.
22. Adjust the room thermostat to obtain a rst stage (W1
only) burner operation.
NOTE: for hybrid models, the control board dip switches
need to be set to 2 stg position to set and verify rst stage
heat. (See Installation Instructions supplied with the unit for
dip switch settings)

WARNING
never use an open fLame to check for gas Leaks.
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.

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.
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.
