Figure 21).
2. Jumper R--W/W1 and R --W2 thermostat connections on
control.
3. When main burners ignite, confirm inlet gas pressure is
between 12.0--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 Figure 15 or Figure 16,orFigure 14)
