WARNING!
TO AVOID PERSONAL INJURY,
BEFORE SERVICING:
(A) DISCONNECT THE AC SUPPLY BY
TURNING OFF THE SERVICE SWITCH
AND AC SUPPLY CIRCUIT BREAKER
(B) SHUT OFF THE GAS SUPPLY AT
THE MANUAL SHUT-OFF VALVE
PROVIDED WITH THE UNIT
(C) ALLOW THE UNIT TO COOL TO A
SAFE TEMPERATURE TO PREVENT
BURNING OR SCALDING
7.2 SPARK IGNITER
The spark igniter (part no. GP-122435-S) is
located in the body of the burner (see Fig. 7.1).
The igniter may be HOT. Care should be
exercised. It is easier to remove the igniter from
the unit after the unit has cooled to room
temperature.
To inspect/replace the Igniter:
1. Set the ON/OFF switch on the control panel,
to the OFF position. Disconnect AC power
from the unit.
2. Remove the side and top panels from the
unit.
3. Disconnect the igniter cable from the igniter
contactor and pull the igniter bushing from
the burner shell.
4. Insert the igniter removal tool into the burner
shell, where the igniter bushing was
removed. Fit the hexagonal end of the tool
over the igniter. (See Fig. 7.2) Unscrew the
igniter from the burner head. Remove the
igniter from the burner shell, by grasping the
contact end of the igniter.

CAUTION!
The igniter may be hot. Allow time for it
to cool before touching.
5. The igniter is gapped at 1/8-inch. If there is a
substantial erosion of the spark gap or
ground electrode, the igniter should be
replaced. If carbon build-up is present, clean
the igniter using fine emery cloth. Repeated
carbon build-up on the igniter is an indication
that a check of the combustion settings is
required (see Chapter 4 for combustion
calibration).
6. Prior to reinstalling the igniter, an anti-seize
compound must be applied to the igniter
threads.
CAUTION!
The igniter must be removed and
installed using the igniter removal tool
provided with the unit(s). Damage to the
burner due to using a socket for removal
and installation of the igniter is not
covered under warranty.
7. Reinstall the igniter using the igniter removal
tool. Do not over tighten the igniter. A slight
snugging up is sufficient. Reinstall the igniter
