Unpack and inspect unit for shipping damage. Ensure proper location and clearances.
WARNING! Installation must be performed by a qualified HVAC technician in accordance with all local codes and manufacturer instructions. Gas and electrical work can be hazardous.
After installation, perform initial startup and system check.
CAUTION! Do not attempt startup if you smell gas. Evacuate area and call gas company immediately.
Primary control is through the thermostat. Unit has integrated control board with diagnostic LED.
Control Board: Manages ignition sequence, blower speed, safety checks, and fault monitoring. LED flashes during normal operation (1 flash = normal heat mode).
Thermostat Settings: Use compatible single-stage or two-stage thermostat. Set to HEAT mode and desired temperature. FAN setting can be AUTO (runs only during heating cycle) or ON (continuous circulation).
Blower Speeds: Variable-speed motor adjusts airflow based on system demand for comfort and efficiency. Cooling speed tap may require adjustment if AC coil is added.
Compatible with most 24VAC thermostats. Standard connections: R (24V power), W (Heat), G (Fan), C (Common).
Tip: Use 18-gauge thermostat wire for runs under 50 feet. Ensure connections are tight.
Regular maintenance ensures efficiency, safety, and longevity.
WARNING! Only qualified personnel should perform internal maintenance. Always turn off gas and electrical power before servicing.
Control board LED flashes to indicate status. Count flashes during fault condition.
| LED Flashes | Description | Action |
|---|---|---|
| 1 | Normal operation (heating) | None |
| 2 | Pressure switch stuck open | Check venting, inducer, pressure switch hose |
| 3 | Pressure switch stuck closed | Check pressure switch, hose, control board |
| 4 | Ignition failure (no flame) | Check gas supply, igniter, flame sensor |
| 5 | Flame sensed when off (rollout) | Check for restricted airflow, heat exchanger |
| 6 | Limit circuit fault | Check filter, airflow, duct restrictions, limit switch |
| 7 | Blower fault after purge | Check blower motor, capacitor, wiring |
| Continuous On | Call for heat (no fault) | Normal standby |
Reset: Power cycle unit after correcting fault. If fault persists, call for service.
This furnace produces carbon monoxide (CO). Proper installation and maintenance are critical.
CAUTION! If you suspect a gas leak or CO presence, evacuate immediately and call emergency services from outside.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Furnace won't turn on | No power, tripped breaker, bad thermostat | Check disconnect switch, circuit breaker, thermostat batteries/settings. |
| Blower runs but no heat | Gas valve off, igniter failure, flame sensor dirty | Ensure gas valve is on; check for fault code; clean flame sensor. |
| Short cycling (turns on/off frequently) | Dirty filter, restricted airflow, high limit tripping | Replace filter; check ducts for blockage; ensure proper temperature rise. |
| Unusual noises (banging, squealing) | Dirty burners, loose parts, blower issue | Have technician inspect burners, heat exchanger, blower wheel, and motor. |
| Pilot/igniter lights but flame goes out | Faulty flame sensor, poor grounding | Clean flame sensor; ensure proper sensor positioning and ground connection. |
| Condensate drain leaking | Clogged drain line, trap not primed | Clear drain line; ensure trap is filled with water to create seal. |
| Error code flashing | See Diagnostic Indicators table | Count flashes, refer to code chart, take appropriate action. |
Reset Procedure: Turn thermostat to OFF. Turn off power at disconnect switch for 30 seconds. Restore power. Set thermostat to HEAT and temperature above room temp.
