18. Refer to furnace wiring diagram and connect wires to
gas valve.
19. Reconnect pressure tubes to gas valve and burner en­
closure. Be sure tubes are not kinked.
20. Using backup wrench, install gas pipe in gas valve.
21. Reconnect gas pipe at ground joint union.
22. Reconnect combustion-air pipe. Tighten hose clamps.
23. Turn on gas and electrical supplies.
A WARNING
Never use matches, candles, flame, or other sources of
ignition to check for gas leakage. Use a soap-and-water
solution. A failure to adhere to this warning can cause a
fire, personal injury, or death.
24. Check for gas leaks.
25. Check furnace operation through two complete operat­
ing cycles.
Check pilot tube and gas valve manifold connection for
gas leaks while furnace is in operation.
26.
27. After condensate starts to drain, check for condensate
leaks.
28. Replace control and blower access panels.
E. Pilot
Check the pilot and clean if necessary at the beginning of
each heating season. The pilot flame should be high enough
for proper impingement of the safety element and to light
the burners. Remove any accumulation of soot and carbon
from the safety element. Check spark electrode gap. See
Fig. 11 for proper spark gap.
F. Electrical Controls and Wiring
NOTE: There may be more than one electrical supply to
unit.
With power disconnected to unit, check all electrical con­
nections for tightness. Tighten all screws on electrical con­
nections. If any smoky or burned connections are noticed,
disassemble the connection, deem all parts, strip wire, and
reassemble properly and securely. Electrical controls are dif­
ficult to check without proper instrumentation; therefore,
reconnect electrical power to unit and observe unit through
two complete operating cycles.
