Installation Requirements

Professional installation required. Verify local codes and obtain permits.

  1. Location selection: Choose area with adequate combustion air and service clearance.
  2. Gas connection: Use approved gas pipe and fittings; pressure test required.
  3. Electrical connection: 120V AC, 60Hz dedicated circuit with proper grounding.
  4. Venting: Use only approved PVC or CPVC materials for high-efficiency venting.
  5. Ductwork: Ensure proper sizing and sealing for optimal performance.

WARNING! Installation must be performed by qualified HVAC technician. Improper installation can cause fire, explosion, or carbon monoxide poisoning.

First-Time Setup

Initial startup must be performed by certified technician.

  1. Verify all connections: Gas, electrical, venting, and condensate drain.
  2. Check gas pressure: Adjust manifold pressure to specifications.
  3. Test safety controls: Verify operation of all limit switches and sensors.
  4. Program thermostat: Set up heating stages and fan controls.
  5. Commission system: Run through complete heating cycle and verify operation.

CAUTION! Do not attempt first startup without proper training and equipment.

Technical Specifications

Controls and Settings

Integrated control board with LED diagnostic lights. Access via control panel cover.

Thermostat Compatibility: Compatible with most 24V thermostats; recommended for two-stage models.

Control Board LEDs: Power (green), Heat (yellow), Error (red). DIP Switch Settings: Heat staging, blower delays, accessory configuration. Temperature Rise: Verify within 35-65°F range. Gas Pressure: Natural gas 3.5" WC, LP 10" WC. Blower Speeds: Adjustable for heating and continuous fan operation.

Venting and Ductwork

High-efficiency condensing furnace requires special venting considerations.

  1. Vent pipe: Use only approved PVC or CPVC; maintain proper slope.
  2. Termination: Follow clearance requirements from windows, doors, and air intakes.
  3. Combustion air: Provide adequate fresh air per local codes.
  4. Duct sizing: Manual D calculation required for proper airflow.
  5. Sealing: Seal all duct joints with approved mastic or tape.

Tip: Regular inspection of vent system prevents blockage and ensures safe operation.

Operating Instructions

Normal operation controlled by thermostat.

  1. Set thermostat to desired temperature and HEAT mode.
  2. Furnace will initiate startup sequence: inducer motor, pressure switch verification, igniter warm-up, gas valve opening.
  3. Once flame established, blower will start after predetermined delay.
  4. During operation, monitor for consistent heating and proper airflow.
  5. Shutdown sequence: Gas valve closes, inducer runs post-purge, blower continues for heat dissipation.

WARNING! Never operate furnace with access panels removed. Keep combustible materials away from furnace.

Maintenance Schedule

Annual professional maintenance recommended.
