KIT S1-33103010000 INCLUDES

1. Ignition control board P/N S1-03103010000

2. Accessory Kit Installation Manual P/N 035-22285-002

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.

REMOVAL OF FAILED IGNITION CONTROL

1. Turn off electrical power.

2. Remove furnace blower access panel.

3. Remove electrical box cover, if required.

4. Label all wires prior to disconnection.

5. Disconnect all wires to failed ignition control.

6. Remove screws or pegs fastening ignition control to electrical

panel.

7. Fasten hole template, included with this installation instruction, to

electrical panel and drill new mounting holes. (If required).

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.

Align the plastic mounting feet with the mounting holes in the electric panel and press on each corner of the control board to seat the mounting feet. Apply only enough pressure to seat the mounting foot or the ignition control may be damaged. 3. 4. 5. Figure 2 shows a typical system wiring diagram, which may vary slightly depending on the furnace model.

This could be caused by a number of problems: faulty inducer, blocked vent pipe, broken pressure switch hose or faulty pressure switch. blower motor or blower wheel. Cycle power (24 VAC) to the control to reset the hard lockout condition after correcting the failure condition. DO NOT assume a pressure switch is faulty.
