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 specific 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 conflict between existing practices and the content of
this manual, the precautions listed here take precedence.
Prior to performing this conversion refer to the National Fuel
Gas Code (ANSI Z223.1) or in Canada, CAN/CGA-B149.2M91 to ensure that the installation is in compliance with those
and all local codes.
PLEASE READ AND FOLLOW THESE INSTRUCTIONS
CAREFULLY.

IMPORTANT INFORMA TION
WARNING”
“This conversion k it shall be installed by a qualified
service agency in accordance with the
manufacturer’s instructions an d all app licabl e
codes and requirements of the authority having
jurisdiction. If the information in these instructions
is not followed exactly, a fire, explosion or
production of carbon monoxide may result causing
property damage, personal injury or loss of life. The
qualified service agency is responsible for the
proper installation of this kit. The installation is not
proper and complete until the operation of the
converted appliance is checked as specified in the
manufacturer’s instructions supplied with the kit.”
Special Warning for Installat ion of Furnaces or Air Handling Units in
Enclose d A r eas such as Garages, Utility Rooms or Parking Areas
Carbon monoxide producing dev ices (suc h as an automobile, spac e
heater, gas water heater, etc.) s hould not be operated in enclos ed ar eas
such as unventilated garages, utility rooms or par k ing areas because of
the danger of carbon monoxide (CO) poisoni ng result ing f r om the exh aus t
emission s . If a furnac e or air handl er is instal led in an enclo sed area such
as a garage, utility r oom or parking area and a c ar bon monoxide producing
device is operated therein, ther e must be ad equate, direct outside
ventilation.

VALVE IDENTIFICATION
Before beginning conversion, the type valve you have must be
identified. 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.

CONVERSION INSTRUCTIONS
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 orifices for damage and drill size (marked
on face with a 55) before installation. Using the 7/16"
wrench, remove all existing natural gas orifices and replace
with the appropriate marked 55 L.P. gas orifices contained
in this kit. Tighten the orifices to prevent gas leaks, but do
not overtighten. Retain the natural gas orifices for future
reconversion.
8. Reinstall the manifold/gas valve assembly into the appliance. Rewire the gas valve.
9. Using a 3/32” Allen wrench, loosen the inlet and outlet pressure tap screw one (1) turn only (DO NOT REMOVE). Attach a length of 5/16” hose to each of the pressure taps.
Connect the 5/16” hose to two (2) separate manometers or
other adequate gauges having a scale range of at least 0”
to 15” of water column.

10.Using a flat blade screwdriver, remove the regulator cover
screw.
11. Using a flat blade screwdriver, remove plastic regulator adjustment screw located beneath the cover screw.
12. Remove the natural gas regulator spring from the regulator
sleeve.
13. Insert the kit (P/N B1880007, WR F92-0999) provided L.P.
regulator spring into the regulator sleeve.
14.Replace the regulator adjustment screw.
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.
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 burn-
ers 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-fired equipment should be ON before
any adjustments are made.
21.Check manifold pressure. For propane gas, the manifold
pressure must be between 9.5” and 10” W.C.
