ON, see Fig.
b. For boards with 3 digit display, navigate to (Htt) and select
(2st), see Fig.
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
