b. Reconnect edge connector at main control box on blower
shelf.
8. Check condition of gasket on cell inlet panel of burner
enclosure. Replace gasket if necessary. (See Fig. 10.)
9. Install gas control assembly in furnace.
10. Install diffuser and burner enclosure front.
11. Reconnect hot surface ignitor and flame sensor leads at
3-circuit connector. .
12. Refer to furnace wiring diagram and connect wires to gas
valve. (See Fig. 17.)
13. Reconnect pressure tubes to gas valve and burner enclosure.
Be sure tubes are not kinked.

15. Reconnect gas pipe at ground joint union.
16. Reconnect combustion-air pipe. Tighten hose clamps.
17. Replace blower door only.
18. Turn ON gas and electrical supplies.
19. Check furnace operation through 2 complete operating cycles.
Look through sight-glass in burner enclosure to check burners.
Burner flames should be clear blue, almost transparent. (See
Fig. 11.)
A WARNING
Never use matches, candles, flame, or other sources of
ignition to check for gas leakage. Use a soap-and-water
solution. Failure to follow this warning could result in a fire,
personal injury, or death.
20. Check for gas leaks.
21. After condensate starts to drain, check for condensate leaks.
22. Replace control door.
Step 5—Clean Condensate Drainage System
1. Disconnect 5/8-in. drain tube from bottom of inducer housing.
(See Fig. 13 or 14.)
2. Disconnect 7/8-in. drain tube from collector box. (See Fig. 13
or 14.)
3. Disconnect condensate drain line from drain trap at compres­
sion fitting.
4. Remove two 1/4-in. screws securing strap on drain trap to:
a. blower housing (upflow furnaces only).
b. bracket from cell panel (downflow furnaces only).
5. Remove drain trap/hose assembly from furnace and flush with
water until clean.
6. Flush external condensate drain line with water until clean.
7. Reassemble condensate drainage system by reversing items 1.
through 5.
Step 6—Hot Surface Ignitor
When removing the burner assembly, use care to avoid breaking
the hot surface ignitor. See Fig. 12 for the conect ignitor
