Always follow safety procedures when working with furnace components.
WARNING! Gas furnaces produce carbon monoxide; ensure proper venting and never operate without flue connection.
Proper installation ensures optimal furnace performance and safety.
CAUTION! Installation should be performed by qualified HVAC technicians only.
Regular maintenance ensures efficient operation and extends furnace lifespan.
Monthly: Check and replace air filters as needed
Seasonal: Inspect burners, heat exchanger, and vent system

Gas valve adjustment and burner maintenance procedures.
Gas Valve: Regulates gas flow to burners. Burner Assembly: Where gas combustion occurs. Pilot Assembly: Standing pilot or electronic ignition. Manifold: Distributes gas to multiple burners. Orifices: Control gas flow rate to each burner.
Turn off power before cleaning. Use soft brush and vacuum for dust removal.
CAUTION! Do not use water or liquid cleaners on electrical components; keep combustion area clean and free of debris.
Concord furnaces include limited warranties covering heat exchanger (20 years), parts (5-10 years), and labor (1 year). Registration required within 90 days of installation. For warranty claims, contact authorized Concord dealers with proof of purchase and installation date. Void if installed by unqualified personnel or used with non-approved parts.
| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Furnace won't start | Power supply/thermostat | Check circuit breaker; verify thermostat settings; ensure door safety switch engaged. |
| No heat (blower runs) | Ignition/gas supply | Check gas valve; verify pilot or ignition operation; inspect flame sensor. |
| Short cycling | Filters/airflow | Replace dirty filters; check for blocked vents; verify proper airflow. |
| Unusual noises | Motor/bearings | Lubricate motor if required; check for loose components; inspect blower wheel. |
| Poor heating | Gas pressure/filters | Verify gas pressure settings; check for restricted airflow; inspect heat exchanger. |
Reset: Turn power off for 30 seconds then restart if lockout occurs.
