Installation

Unpack and inspect contents. Ensure proper location with adequate clearance.

1. Connect gas line: Use approved gas piping; check for leaks with soap solution.
2. Connect electrical: Use dedicated 120V AC circuit; ensure proper grounding.
3. Connect thermostat: Use low-voltage wiring to thermostat location.
4. Connect venting: Install proper exhaust and intake piping according to local codes.
5. Check air filters: Install clean filters before operation.

WARNING! Installation must be performed by qualified technician. Gas leaks can cause explosion. Ensure proper ventilation.

First-Time Setup

Power on furnace; follow initial startup procedure.

1. Set operating mode: Press MODE to select HEAT operation.
2. Set temperature: Use TEMP buttons to desired comfort level.
3. Program thermostat: Set schedule if using programmable thermostat.
4. Test safety features: Verify proper operation of safety shut-off systems.
5. Check airflow: Ensure all vents are open and unobstructed.

CAUTION! Allow furnace to complete initial startup cycle. Do not interrupt during first operation.

Controls and Settings

Access settings via control panel or remote thermostat. Front Panel: POWER, MODE, TEMP UP/DOWN, FILTER RESET.

Remote Thermostat: Temperature setting, schedule programming, system mode, fan control, filter status.

Heating Modes: HEAT (automatic temperature control), OFF (system shutdown), FAN ONLY (circulation without heat). Temperature Settings: 50°F to 90°F range. Fan Control: AUTO (cycles with heat), ON (continuous operation). Filter Monitoring: Automatic reminder when replacement needed.

Connecting Thermostat

Compatible with most 24V thermostats. Standard wiring: R (power), W (heat), G (fan), Y (cool), C (common).

1. Turn off furnace power at circuit breaker.
2. Remove thermostat cover and connect wires to appropriate terminals.
3. Match wire colors to terminal labels (R-red, W-white, G-green, Y-yellow, C-blue).
4. Select thermostat type in furnace control board settings.
5. Restore power and test operation.

Tip: Use programmable thermostat for energy savings up to 15%.

Operating Modes

Multiple operating modes for efficiency and comfort.

1. Heat Mode: Automatic temperature maintenance; furnace cycles on/off as needed.
2. Fan Only: Continuous air circulation without heating.
3. Vacation Mode: Maintains lower temperature (50°F) to prevent freezing.
4. Smart Recovery: Learns heating cycle time to reach set temperature at scheduled times.
5. Filter Saver Mode: Reduces fan speed when filter needs replacement.

WARNING! Do not set temperature below 50°F in occupied spaces to prevent pipe freezing.

Maintenance Features

Self-diagnostic system: Error codes displayed for common issues. Filter monitoring: Automatic reminder when replacement needed. Safety lockout: Prevents operation during fault conditions.

Care & Cleaning

Turn off power before maintenance. Replace filters every 1-3 months. Clean flame sensor annually. Keep area around furnace clear of debris.

CAUTION! Do not use compressed air to clean interior components. Keep electrical components dry.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Furnace won't start	Power/thermostat	Check circuit breaker; verify thermostat settings; ensure gas valve open.
No heat	Pilot/ignition	Check pilot light; verify igniter operation; check gas supply.
Short cycling	Filter/thermostat	Replace dirty filter; check thermostat location; verify proper sizing.
Blower runs continuously	Fan setting	Change fan setting from ON to AUTO; check thermostat programming.
Unusual noises	Mechanical issues	Check for loose components; lubricate motor if applicable; inspect blower wheel.
Error code displayed	System fault	Refer to error code chart in manual; reset system; call for service if persistent.

Reset: Turn power off for 30 seconds, then restore.
