System Operation

Normal heating cycle operation and temperature control.

Set thermostat to desired temperature in HEAT mode.
System initiates ignition sequence when heat is demanded.
Inducer motor starts to establish draft.
Hot surface igniter glows and gas valve opens.
Flame sensor confirms ignition; main burner operates.
Blower motor starts after heat exchanger warms up.
System cycles off when thermostat setpoint is reached.

Tip: Maintain consistent temperature settings for optimal efficiency.

Maintenance Procedures

Regular maintenance ensures optimal performance and safety.

Monthly: Check and replace air filter as needed.
Seasonal: Inspect vent system for obstructions.
Annual: Professional inspection and cleaning required.
Clean burners and heat exchanger surfaces.
Check gas pressure and combustion analysis.
Lubricate blower motor if required.
Test safety controls and operation.

WARNING! Turn off power and gas supply before performing any maintenance.

Safety Features

Multiple safety systems protect against hazardous conditions. Flame Rollout Switch: Shuts off gas if flame escapes burners. High Limit Switch: Prevents overheating of heat exchanger. Pressure Switch: Ensures proper venting before ignition. Flame Sensor: Confirms burner ignition within trial period. Ignition Lockout: Prevents repeated ignition attempts.

Care & Cleaning

Regular cleaning maintains efficiency and extends system life.

Clean air filters monthly. Keep area around furnace clear of combustible materials. Clean burners and heat exchanger annually. Inspect and clean condensate drain system. Wipe exterior surfaces with damp cloth.

CAUTION! Never use water or cleaning solutions on electrical components. Always disconnect power before cleaning.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Furnace won't start	Power, thermostat, safety lockout	Check power supply; verify thermostat settings; reset system.
No heat	Gas supply, ignition, filter	Check gas valve; verify pilot/ignition; replace dirty filter.
Short cycling	Dirty filter, limit switch	Replace air filter; check high limit switch operation.
Blower won't stop	Thermostat setting, relay	Check thermostat fan setting; inspect blower relay.
Unusual noises	Motor, blower wheel, ducts	Inspect blower assembly; check for loose components.

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