UNIT DAMAGE HAZARD
Failure to follow this caution may result in premature failure
of the igniter.
The igniter is fragile. DO NOT allow it to hit burner box parts
while removing or replacing it.
e. If replacement is required, replace igniter on igniter bracket
and then install assembly into burner box to avoid damage
to the igniter.
6. To replace igniter and bracket assembly, reverse items 5a
through 5d.
7. Reconnect igniter wire connection and insert the igniter wires
in the slot in the manifold grommet, dressing the igniter wires
to ensure there is no tension on the igniter itself. (See Fig.7.)
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in electrical shock,
personal injury, or death.
Igniter wires must be securely placed in slot in manifold
grommet or else they could become pinched or severed and
electrically shorted.
8. Reinstall burner box cover.
9. Turn on gas and electrical supplies to furnace.
10. Verify igniter operation by initiating control board self-test
feature or by cycling thermostat.
11. Replace main furnace door.
