Maintenance

10-second interval, then the ignition control will de- energize the gas valve.

6.The ignition control is designed to repeat this “trial for ignition” a total of three times. If, at the end of the third trial, flame still has not been established, then the ignition control will try to light again 1 hour later. The 1-hour retry is indefinite. The ignition control can be reset by interrupting the unit power or the thermostat circuit.

7.When the thermostat is satisfied, the draft motor and gas valve are de-energized. The blower motor will continue to run for a short period after the furnace is shut down.

Blower Delay – Heating

The on/off delay of the circulating air blower is controlled by a timing circuit in the integrated ignition control. Timings are not adjustable. The blower “ON” delay is 30 seconds after the burners are lit and the blower “OFF” timing is 120 seconds after shutting down the burners.

Safety Controls

The control circuit includes the following safety controls:

Limit Control This control is located inside the heating compartment and is designed to open at abnormally high circulating air temperatures. It resets automatically. The limit control operates when a high temperature condition, caused by inadequate airflow, occurs. This closes the main gas valve, and the circulation air blower continues to operate in this situation.

Pressure Switch If the draft motor should fail, the pressure switch prevents the spark electrode and gas valve from being energized.

Flame Sensor If the ignition control does not receive a signal from the flame sensor indicating that the burners have established flame, the main gas valve closes after the 10- second trial for ignition period.

Rollout Switch The switch is located on the left side of burner box. In the event of a sustained main burner rollout, the rollout switch shuts off the ignition control and closes the main gas valve. To reset, push the button on top of the switch.

Auxiliary Limit This control is located in the side of the circulation air blower housing. The switch opens and shuts off the blower/ignition control and closes the main gas valve should the circulation blower fail to operate. This control resets automatically.

High Altitude

The input rate shown on the rating plate is for elevations up to 2000 feet. For elevations from 2001 to 4500 feet, the input rate is reduced by 5%. For elevations above 4500 feet, refer to the National Fuel Gas Code Z223.1 (latest edition) or the Canadian Installation Codes CAN/CGA-B149.1 & B149.2 for further details.

Secure Owner’s Approval

When the system is functioning properly, secure the owner’s approval. Show the owner the location of all disconnect switches and the thermostat. Instruct the owner on how to start and stop the unit and how to adjust temperature settings within the limitations of the system.

Periodic inspection and maintenance normally consists of changing or cleaning the filters and cleaning the outdoor coil. On occasion, other components of the furnace may also require cleaning.

WARNING

Shut off all electrical power to the unit before conducting any maintenance procedures. Failure to do so could cause personal injury.

Filters

Filters are not supplied with the unit. Inspect once a month. Replace disposable or clean permanent type as necessary.

Do not replace permanent type with disposable.

Motors

Indoor and outdoor fan and vent motors are permanently lubricated and require no maintenance.

Outdoor Coil

Dirt and debris should not be allowed to accumulate on the outdoor coil surface or other parts in the air circuit. Cleaning should be as often as necessary to keep coil clean. Use a brush, vacuum cleaner attachment, or other suitable means. If water is used to clean the coil, be sure the power to unit is shut off prior to cleaning. Care should be used when cleaning the coil so that the coil fins are not damaged.

Do not permit the hot condenser air discharge to be obstructed by overhanging structures or shrubs.
