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.

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
WARNING
To avoid personal injury, properTy damage or deaTh, due
To leaking gas, conTacT your propane supplier abouT
insTalling a gas deTecTing warning device. iron oxide
(rusT) can reduce The level of odoranT in propane gas.
a gas deTecTing device is The only reliable meThod To
deTecT a propane gas leak.
CAUTION
To avoid The risk of properTy damage, personal injury or
fire, shuT off gas supply firsT, Then disconnecT The elec-
Trical supply before proceeding wiTh conversion.
BEFORE BEGINNING CONVERSION:
VALVE IDENTIFICATION
Before beginning conversion, the type valve you have
must be identied. Compare the gas valve presently on the
equipment to the drawing below to identify the correct valve
you are working with. Page numbers for the instructions for
that valve are below each drawing.
White-Rodgers 36G22 and 36J22
Instructions for these valves start on page 3.

CONVERSION INSTRUCTIONS
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 valves.
NOTE: For low NOx models, see page 6 for NOx screens.
1. Turn off gas supply to the furnace.
2. Turn off the electrical power to the furnace.
3. Remove the furnace control access panel.
4. Separate the gas supply union and remove associated
downstream piping.
NOTE: Always use a backup wrench when removing or
replacing piping to avoid any undue strains or rotation of
controls.
5. Remove the wires from the gas valve.
6. Remove the 4 sheet metal screws that fasten the manifold/
gas valve assembly to the burner box.
7. 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 re-
place with the appropriate 1.25mm L.P. gas orices con-
tained in this kit. Tighten the orices to prevent gas leaks,
but do not overtighten. Retain the natural gas orices for
future reconversion.
8. Install water manometer using Valve Pressure Check Kit
P/N 0151K00000S included with this kit. Using the includ-
ed 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 in-
cluded 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.
9. Using a at blade screwdriver, remove the regulator cover
screw.
10. Using a at blade screwdriver, remove plastic regulator
adjustment screw located beneath the cover screw.
11. Remove the natural gas regulator spring from the regulator
sleeve.
12. Insert the kit (P/N B1880007, WR F92-0999) provided
L.P. regulator spring into the regulator sleeve.
13. Replace the regulator adjustment screw.
14. Reinstall the manifold/gas valve assembly into the appli-
ance. Rewire the gas valve.
15. Apply a liberal amount of pipe joint compound or pipe
thread tape to the threads and reassemble the piping
previously removed. NOTE: the pipe joint compound or
pipe thread tape must be resistant to L.P. gas.
16. Turn on the gas supply and check for leaks.
WARNING
To avoid The possibiliTy of explosion or fire, never use a
maTch or open flame To TesT for leaks.
17. Turn on the electrical supply.
18. Adjust the room thermostat to allow for constant operation.
19. If you have the correct manifold pressure and the
burners do not light, there may be air trapped in the
lines. Follow these instructions:
To check for air trapped in the supply line: Verify line
pressure is in the correct range. If manifold pressure is
indicated during the ignition trial, the valve is opening and
air may be in the line.
Units with hot surface ignitors: The valve will not open
until the ignitor is at the proper temperature (glowing
brightly).
Units with spark ignition: The valve will open as soon
as the spark starts. If no manifold pressure is indicated
during the trial for ignition, please return to step 13 to
ensure the correct spring was used and to ensure the
regulator adjustment is near the bottom of the adjustment
range.
20. If gas inlet pressure falls outside the range of 11” and 13”
W.C. after the unit has been in operation for 15 minutes,
adjust the gas supply pressure (not manifold pressure),
check piping size, etc., and/or consult with local utility.
NOTE: Any other gas-red equipment should be ON
before any adjustments are made.
21. Check manifold pressure. For propane gas, the manifold
pressure must be between 9.7” and 10.3” W.C.
