VCT Blower Motor

1. Enable two-stage thermostat on control board by:

a. For boards with DIP switches, turn SW1-2 on furnace control 

ON, see 

Fig. 21

.

b. For boards with 3 digit display, navigate to (

Htt

) and select 

(

2st

), see 

Fig. 21

. See furnace installation manual for additional 

instructions.

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. 13

 or
