1. Turn Setup Switch SW1-2 on furnace control ON, see
2. Jumper R-W/W1 and R-W2 thermostat connections on control.
3. When main burners ignite, confirm inlet gas pressure is between
4.5-in. w.c. and 13.6-in. w.c.
4. Remove jumper across R-W/W1 and R-W2 thermostat connections
to terminate call for heat.
5. Turn furnace gas valve switch to OFF position.
6. Turn gas supply manual shutoff valve to OFF position.
7. Turn off furnace power supply.
8. Remove manometer and on some models remove pressure tap
fitting.
9. On some models, apply pipe dope sparingly to the end of inlet gas
pipe plug and install into unused end of 1/8-in. (3 mm) tee. Use a
small back-up wrench on tee when tightening gas inlet pipe plug.
Or, on some models, tighten set screw on inlet tower pressure tap
with a 3/32-in. hex wrench, see

WARNING
!
FIRE OR EXPLOSION HAZARD
Failure to follow this warning could result in personal injury, death,
and/or property damage.
Never test for gas leaks with an open flame. Use a commercially
available soap solution made specifically for the detection of leaks to
check all connections. A fire or explosion may result causing property
damage, personal injury or loss of life.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

GAS INPUT RATE INFORMATION
23.
See furnace rating plates,see
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.
SET GAS INPUT RATE
Single Stage Gas Valve
1. Jumper R and W thermostat connections to call for heat, see
Fig.
20.
2. Check manifold orifices for gas leaks when main burners ignite.
3. Adjust gas manifold pressure, see
4. Remove cap that conceals gas valve regulator adjustment screw.
5. Turn adjusting screw counterclockwise (out) to decrease manifold
pressure or clockwise (in) to increase manifold pressure.
6. Replace gas valve regulator seal cap.
