For Single Stage and Two Stage Furnaces:
Determine natural gas orifice size and manifold pressure for correct
input at installed altitude by using Table 4 for Single Stage furnaces and
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 Table 4 or Table 5.
For Canada altitudes of 2000 to 4500 ft., use U.S.A. Altitudes of 2001 to
3000 ft. in Table 4 or Table 5.
4. Find closest natural gas heat value and specific gravity in Table 4 or
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.
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.

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 4 percent for each 1000 ft. (305 M) above sea level.
In Canada, the input rating must be derated by 10 percent for altitudes of
2000 ft. to 4500 ft. (610 M to 1372 M) above sea level.

GAS INPUT RATE INFORMATION
See furnace rating plates, see Fig. 5, Fig. 6, or Fig. 7, for input rate. The
input rate for natural gas is determined by manifold pressure and orifice
size.
Modulating gas valve must be set for Maximum Heat first and then set
for Minimum heat on Modulating furnaces.
Two-Stage gas valve must be set for High Heat first and then set for Low
Heat on Two-Stage furnaces.
Furnace gas input rate on 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. (610M) 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. (610 M) to 4500 ft. (1372 M) above sea level.
The Conversion Kit Rating Plate accounts for high altitude derate.

24. Set room thermostat to desired temperature.
25. After making the required manifold pressure adjustments, check
and adjust the furnace temperature rise per the furnace installation
instructions.
Modulating Gas Valve
For proper operation and long term reliability, the manifold pressure
must be adjusted as specified on the conversion kit rating plate.
The modulating furnace manifold pressure is set at two points. The first
point is Maximum Heat. The second point is Minimum Heat. Do not
adjust Intermediate Heat manifold pressure. Intermediate Heat manifold
pressure can be checked as part of the temperature rise, but is not
adjustable. Always adjust Maximum Heat first, then Minimum Heat.
NOTE: Use care when performing adjustments. Gas valve adjustment is
performed by turning a rotary adjustment switch inside the gas valve
with a small straight blade screwdriver. Excessive force can break or
bend the rotary adjustment switch making it non-adjustable.
To adjust manifold pressure to obtain input rate for Maximum
Heat:
1. Turn Setup switch SW1-2 to ON.
2. Verify Set-up switch SW4-2 is turned OFF.
3. Jumper the R to W/W1 and W2 thermostat connections at the
furnace control board.
4. After the main burners ignite and the blower starts, confirm
Maximum Heat manifold pressure is correct, based on the manifold
pressure table on the Conversion Kit Rating Plate.
5. To adjust the Maximum Heat manifold pressure, Slowly turn the
rotary adjustment switch counterclockwise to decrease manifold
pressure or clockwise to increase manifold pressure.
6. Turn rotary adjustment switch no more than one click per second
until you obtain the required manifold pressure.
Main burner flame should be clear blue, almost transparent.
To adjust manifold pressure to obtain input rate for Minimum Heat:
1. Remove the jumper from W2 at the thermostat connections at the
furnace control board control.
2. Wait until the burners and the blower transitions to Minimum Heat.
3. Verify the Minimum Heat manifold pressure is correct, based on the
manifold pressure table on Conversion Kit Rating Plate.
4. To adjust the Minimum Heat manifold pressure, Slowly turn the
rotary adjustment switch counterclockwise to decrease manifold
pressure or clockwise to increase manifold pressure.
5. Turn rotary adjustment switch no more than one click per second
until you obtain the required manifold pressure. This adjustment
will not affect the previous Maximum Heat adjustment.
After adjusting the manifold pressure, allow the furnace to operate an
additional 5 minutes before checking Minimum Heat Temperature rise.
Furnace must operate within ranges of temperature rise specified on the
furnace rating plate. Determine air temperature rise as follows:
1. Place thermometers in return and supply ducts as near furnace as
possible. Be sure thermometers do not see heat exchanger so that
radiant heat does not affect readings. This practice is particularly
important with straight-run ducts.
2. When thermometer readings stabilize, subtract return-air
temperature from supply-air temperature to determine air
temperature rise.
3. Allow the furnace to run for at least 10 minutes before checking
Temperature Rise.
If the temperature rise is too high or too low in Minimum Heat:
1. Remove jumpers from R and W/W1.
2. Wait until the blower off delay is completed.
3. Turn 115 VAC power off.
4. Check the position of Heat Rise Adjustment Switch SW1-3. When
set to ON, airflow is raised 18% higher for Minimum Heat and
Intermediate Heat. Factory default position is OFF.
5. Turn 115 VAC power on.
6. Jumper R to W/W1 and W2.
7. After burners ignite and blower starts allow the furnace to run for at
least 10 minutes before checking Temperature Rise.
Maximum Heat Temperature Rise
If the temperature rise is too high or too low in Maximum Heat:
1. Remove jumpers from R, W1 and W2.
2. Wait until the blower off delay is completed.
3. Turn 115 VAC power off.
4. Check the position of the Efficiency/Comfort Adjustment switch
SW1-4. When set to OFF (Efficiency Mode), airflow is 10% higher
for Minimum, 7.5% for Intermediate Heat, and 17.5% for
Maximum Heat. Factory default position is ON (Comfort Mode).
5. Turn 115 VAC power on.
6. Re-check Minimum Heat Temperature Rise.
7. Remove jumpers across thermostat connections to terminate the
