[]NIT DAMAGE HAZARD
Failure to follow this caution may result in unit damage.
Furnace MUST have low NOx devices removed prior to
operating furnace on propane gas.
For NOx device removal, follow these additional steps:
1. Remove the screw underneath the heat exchanger inlet that
secures the NOx device in the heat exchanger. (See Fig.
35.)

Fig. 35 - NOx Device
2. Use a pair of needle nose pliers to remove the NOx device.
3. Squeeze the sides of the device, if necessary, to remove
from the heat exchanger.
4. Re-install screw in hole underneath heat exchanger inlet.
NOTE: It is very IMPORTANT to reinstall the NOx bracket
mounting screw.
5. Repeat steps for each heat exchanger.
ORIFICE SELECTION/DERATE
[]NIT DAMAGE HAZARD
Failure to follow this caution may result in unit damage.
DO NOT re-drill burner orifices. Improper drilling may
result in burrs, out-of-round holes, etc. Obtain new orifices
if orifice size must be changed. (Fig. 36.)

Fig. 36 - Burner Orifice
Refer to conversion kit rating plate 337704-204 to determine
main burner orifice size. (See Fig. 37.)
Furnace gas input rate on furnace rating plate is for installations at
altitudes up to 2000 ft.
In the U.S.A.; the input rating for altitudes above 2000 ft. must
be reduced by 2 percent for each 1000 ft. above sea level.
In Canada, the input rating must be derated by 5 percent for
altitudes of 2000 ft. to 4500 ft. above sea level.
The Conversion Kit Rating Plate accounts for high altitude
derate.
Install main burner orifices. Do not use Teflon tape.
Finger-tighten orifices at least one full turn to prevent
cross-threading, then tighten with wrench. There are enough
orifices in each kit for largest furnace. Discard extra orifices.
INSTALL ORIFICES
Install main burner orifices. Do not use Teflon tape.
Finger-tighten orifices at least one full turn to prevent
cross-threading, then tighten with wrench. There are enough
orifices in each kit for largest furnace. Discard extra orifices.
NOTE: DO NOT reinstall the manifold at this time.
INSTALL MIXER SCREWS
NOTE: There are 2 sets of mixer screws. One set is for
Condensing gas furnaces, the other set is for Non-condensing gas
furnaces. Use only the parts in the bag marked "REQUIRED
FOR THE CONVERSION OF NON-CONDENSING GAS
FURNACES TO PROPANE GAS"
See Fig. 38 to verify you have the correct set of mixer screws.
1. Locate the dimple on each burner venturi tube. If you can-
not locate the dimple, refer to Fig. 39 for location of the
mixer screw.
2. Drill a 7/64-in. (2.8 mm) hole (supplied in kit) in each
dimple.
3. Install a mixer screw in each drilled hole drilling as
straight as possible. The screw head should be flush with
the top of the burner venturi.
