AGAGC9PNS01B Gas Conversion Kit, Propane to Natural: Installation Instructions
3. Support the manifold and remove the four (4) screws that secure the
manifold assembly to the burner box and set aside.
4. Note the location of the green/yellow wire ground wire for
re-assembly later, see
Fig.
5. Remove wires from both rollout switches, see
6. Slide one-piece burner assembly out of slots on sides of burner box,
see
Fig.
3.
7. Remove the flame sensor from the burner assembly.
8. Remove the orifices from the manifold and discard.

UNIT 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, see
Fig.

For Single Stage and Two Stage Furnaces:
Determine natural gas orifice size and manifold pressure for correct
input at installed altitude by using
Table 5
for Two-Stage furnaces.
1. Obtain yearly heat−value average (at installed altitude) for local gas
supply.
2. Obtain yearly specific−gravity average for local gas supply.
3. Find installation altitude in
A11407
For Canada altitudes of 2000 to 4500 ft., use U.S.A. Altitudes of 2001 to
3000 ft. in
Table 4
or
4. Find closest natural gas heat value and specific gravity in
Table
5.
5. Follow heat−value line and specific−gravity line to point of
intersection to find orifice size and manifold pressure settings.
For Modulating Furnaces:
Follow Steps 1 and 2 above.
For Step 3 use:
Table 6
for all sizes (20,000 BTUH/Max-Heat/8,000 BTUH Min-Heat
per burner) except 60,000 BTUH models in a 21-in. wide cabinet.
A11403
Table 7
for 60,000 BTUH models in a 21-in. wide cabinet. (20,200
BTUH Max-Heat/8,000 BTUH Min-Heat per burner)
1. For both tables, follow heat−value line and specific-gravity line to
point of intersection to find orifice size and manifold pressure
settings.
For all furnaces:
Furnace gas input rate on furnace rating plate is for installations at
altitudes up to 2000 ft. (610 M).
In the U.S.A.; the input rating for altitudes above 2000 ft. (610 M) must
be reduced by 2 percent for each 1000 ft. (305 M) above sea level.
In Canada, the input rating must be derated by 5 percent for altitudes of
2000 ft. to 4500 ft. (610 M to 1372 M) above sea level.
The Conversion Kit Rating Plate accounts for high altitude derate.
