Installation Requirements

Professional installation required. Verify local codes and obtain permits.

  1. Location selection: Install in dry, well-ventilated area with proper clearances.
  2. Gas connection: Use black iron pipe with proper sizing; pressure test required.
  3. Electrical connection: 120V AC power supply with proper grounding.
  4. Venting: PVC pipe for intake and exhaust; maintain proper slope.
  5. Ductwork: Properly sized and sealed duct system.

WARNING! Gas appliances can be dangerous if improperly installed. Use licensed HVAC professional.

First-Time Setup

Initial startup must be performed by qualified technician.

  1. Verify all connections: Gas, electrical, venting, and ductwork.
  2. Check gas pressure: Adjust manifold pressure per specifications.
  3. Test safety controls: Verify pressure switches, limit switches, rollout switches.
  4. Program thermostat: Set heating schedule and temperature preferences.
  5. Commission system: Run through complete heating cycle.

CAUTION! Never attempt initial startup without proper training and equipment.

Technical Specifications

Controls and Settings

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

Status Lights: Green for normal operation, flashing codes for diagnostics.

Thermostat Settings: Heat/Off/Auto, Fan On/Auto, Temperature setpoint. DIP Switches: Blower delays, heating speed, accessory configuration. Diagnostic Codes: Flash patterns indicate specific issues for troubleshooting.

Venting and Ductwork

Direct vent system using separate intake and exhaust pipes.
