5. Install the remaining manifold mounting screws.
6. Connect the wires to the flame sensor and hot surface igniter.
7. Connect the connector harness to gas valve.
NOTE: Do not use PTFE thread-seal tape.
8. Insert the gas pipe through the grommet in the casing. Apply a thin
layer of pipe dope to the threads of the pipe and thread the pipe by
into the gas valve.
NOTE: Use a back-up wrench on the gas valve to prevent the valve
from rotating on the manifold or damaging the mounting to the burner
box.
9. With a back-up wrench on the inlet boss of the gas valve, finish
tightening the gas pipe to the gas valve.
10. Turn gas on at electric switch on gas valve.
CHECK INLET GAS PRESSURE
NOTE: This kit is to be used only when inlet gas pressure is between
4.5-in. w.c. and 13.6-in. w.c.
1. On some models, remove 1/8-in. (3 mm) pipe plug from inlet
pressure tap (see Fig. 18 and Fig. 19 ) and insert pressure tap. Or, on
some models, loosen set screw on inlet tower pressure tap no more
than one full turn with the 3/32-in. hex wrench, see Fig. 11 or
Fig. 12 .
2. Verify manometer is connected to inlet pressure tap on gas valve,
see Fig. 11 or Fig. 12 .
3. Turn on furnace power supply.
4. Turn gas supply manual shutoff valve to ON position.
5. Turn furnace gas valve switch to ON position.

Fig. 20 – Example of Single Stage Furnace Control
1. Jumper R-W thermostat connections on control.
2. When main burners ignite, confirm inlet gas pressure is between
4.5-in. w.c. and 13.6-in. w.c.
3. Remove jumper across R-W thermostat connections to terminate
call for heat.
4. Turn furnace gas valve switch to OFF position.
5. Turn gas supply manual shutoff valve to OFF position.
6. Turn off furnace power supply.
7. Remove manometer and on some models remove pressure tap
fitting.
8. On some models, apply pipe dope sparingly to 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. 11 or Fig. 12 .
CAUTION
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in unit damage.
DO NOT operate furnace more than one minute to check inlet gas
pressure, as conversion is not complete at this time.
WARNING
!
FIRE, EXPLOSION, ELECTRICAL SHOCK
HAZARD
Failure to follow this warning could result in personal injury, death or
property damage.
Gas supply MUST be shut off before disconnecting electrical power
and proceeding with conversion.
WARNING
!
