INSTALLATION
The required number of steps to remove the failed ignition control and
install the new ignition control will vary depending on the furnace model.
However the wire connections will remain the same.
Some models (certain upflow 90% models) will require that the sheet
metal control box be replaced. The existing door switch and transformer
will be re-used.
Some models (BGU Series) will require that new holes be drilled in the
existing control box and that the transformer be relocated.
Some models will need new mounting holes to be drilled in the existing
panel. Use the drill template on the last page of these instructions as a
guide.

Disconnect electrical power to the furnace before installing this con-
trol. Failure to cut power could result in an electrical shock or equip-
ment damage.
Label all wires prior to disconnection when servicing controls. Wiring
errors can cause improper and dangerous furnace operation. Verify
proper operation after servicing.
If power is applied and 9 red flashes immediately occur, check for
correct transformer phasing. Refer to the description for the 9 RED
FLASHES of the LED indicator on page 3.
All wiring must be in accordance with both the National Electric
Code, latest edition, and all local electrical codes.
