[]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.)

A02195

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.
