Installation Requirements

Professional installation required. Verify local codes and obtain permits.

Location: Install in dry, clean area with adequate clearance for service.
Gas connection: Use approved black iron pipe with proper sizing.
Electrical: 120V AC power with proper grounding and disconnect.
Venting: Category IV vent system required for proper combustion.
Combustion air: Ensure adequate fresh air supply per local codes.

WARNING! Gas furnaces produce carbon monoxide. Proper installation and venting are critical for safety. Installation must be performed by qualified technician.

First-Time Setup

Initial startup must be performed by qualified technician.

Verify installation: Check all connections, clearances, and venting.
Gas pressure: Adjust manifold pressure to specifications.
Airflow: Set blower speeds for heating operation.
Combustion: Verify proper combustion analysis readings.
Test operation: Cycle through all modes and verify safety controls.

CAUTION! Never attempt to adjust gas pressure or combustion settings without proper training and equipment.

Safety shutdown: Multiple safety controls monitor operation.

WARNING! If furnace locks out on safety, do not reset repeatedly. Contact qualified service technician.

Maintenance Schedule

Annual professional maintenance recommended. Monthly homeowner maintenance.

Homeowner: Monthly filter inspection/replacement, keep area clear, visual inspection.

Professional: Annual combustion analysis, heat exchanger inspection, blower cleaning, safety control testing, electrical component inspection.

Safety Features

Multiple safety systems: Flame rollout switches, high limit switches, pressure switches, flame sensor, igniter safety, control board diagnostics.

CAUTION! Carbon monoxide detectors required in home. Never disable safety controls.

Regulatory Information

ANSI Z21.47: Certified for natural gas operation. UL listed. Meets DOE efficiency standards. Installation must comply with National Fuel Gas Code (NFPA 54), local building codes, and manufacturer specifications. For support, contact authorized dealer or manufacturer technical support.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Furnace not starting	Power, thermostat, switch	Check power supply, thermostat setting, service switch position.
No heat	Gas supply, igniter	Verify gas valve on, check igniter operation, review diagnostic codes.
Short cycling	Filter, airflow, limit switch	Replace filter, check airflow restrictions, inspect limit switch.
Blower not running	Motor, capacitor, control	Check blower motor operation, capacitor, control board signals.
Lockout condition	Safety device tripped	Reset power, check diagnostic lights, contact technician if recurring.

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

Service: Contact authorized dealer or qualified HVAC technician.
