Modulating Gas Valve

L11F061

Fig. 23 – Example of Modulating Furnace Control for ECM Blower 

Motor

1. Turn Setup Switch SW1-2 on furnace control ON, see 

Fig. 23

.

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 

Fig. 17

.

CHECK FURNACE AND MAKE ADJUSTMENTS

1. Be sure main gas and electric supplies to furnace are off.
2. On some models, remove 1/8-in. (3 mm) pipe plug from manifold

pressure tap on the outlet end of gas valve and insert pressure tap.

Or,  on  some  models,  loosen  the  set  screw  on  manifold  tower

pressure  tap  no  more  than  one  full  turn  with  the  3/32-in.  hex

wrench.

3. Attach  manometer  to  manifold  pressure  tap  on  gas  valve,  see

Fig. 11

Fig. 12

Fig. 13

Fig. 14

, or 

Fig. 17

.

4. Turn gas supply manual shutoff valve to ON position.
5. Turn furnace gas valve switch to ON position.
6. Check all threaded pipe connections for gas leaks.
7. Turn on furnace power supply.

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.

SET GAS INPUT RATE

Fig. 24 – Burner Flame

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 

Table 4

.

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.

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.
