Installation Requirements

Professional installation required. Verify local codes and obtain permits.

  1. Location: Install in dry, clean area with proper clearance (minimum 1 inch sides, 6 inches front).
  2. Venting: Use 2-inch PVC pipe for intake and exhaust; maintain proper slope for condensation drainage.
  3. Gas connection: Use black iron pipe with drip leg; pressure test for leaks.
  4. Electrical: Connect to dedicated 120V circuit; proper grounding required.
  5. Ductwork: Ensure proper return and supply air sizing; install filter rack.

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

First-Time Setup

After installation, perform initial startup procedure.

  1. Verify all connections: Gas, electrical, venting, and condensate drain.
  2. Install air filter: Use proper size (16x25x1 standard).
  3. Power on: Turn on electrical power and gas supply.
  4. Thermostat setup: Set to heat mode with desired temperature.
  5. Initial ignition: System will perform self-check and ignition sequence.
  6. Check operation: Verify proper flame, airflow, and temperature rise.

CAUTION! Never bypass safety controls. Ensure proper combustion air supply.

Specifications

Controls and Operation

Integrated control board manages all furnace functions with LED status light.

Control Board LED Codes: Steady on = normal operation; 1 flash = pressure switch error; 2 flashes = ignitor failure; 3 flashes = flame sense error; 4 flashes = limit switch open; 5 flashes = rollout switch open.

Thermostat Operation: Compatible with standard 24V thermostats. Heat mode activation, fan control (auto/on), system shutdown.

Blower Speeds: ECM motor automatically adjusts airflow based on system requirements. Cooling speed set for AC compatibility.

Thermostat Connection

Standard 24V thermostat wiring connections at control board.

  1. Turn off power to furnace before wiring.
  2. Connect thermostat wires: R (24V), W (heat), G (fan), C (common).
  3. For AC: Connect Y (cooling) and C (common).
  4. Secure connections and restore power.

Tip: Use 18-gauge thermostat wire for runs up to 100 feet.

Maintenance Procedures

Regular maintenance ensures optimal performance and safety.

  1. Monthly: Check and replace air filter as needed.
  2. Annual: Professional inspection and cleaning.
  3. Clean flame sensor: Use fine sandpaper or steel wool.
  4. Check vent system: Ensure no obstructions in PVC pipes.
  5. Inspect heat exchanger: Look for cracks or corrosion.
  6. Verify gas pressure and combustion analysis.
  7. Lubricate blower motor if required (most ECM motors are sealed).

WARNING! Only qualified technicians should perform internal maintenance. Turn off gas and electrical power before servicing.

Safety Features

Multiple safety systems protect against hazardous conditions.

Care & Cleaning

Keep furnace area clean and unobstructed.

Exterior: Wipe with dry cloth only. Interior: Professional cleaning only.

Air filter: Replace every 1-3 months depending on usage and environment.

Vent pipes: Keep clear of snow, ice, and debris.

CAUTION! Never use water or cleaning chemicals on furnace components. Keep combustible materials away from furnace.

Troubleshooting

SymptomPossible CauseCorrective Action
Furnace won't startPower, thermostat, door switchCheck circuit breaker, thermostat settings, ensure door properly closed.
No heatGas supply, ignitor, flame sensorVerify gas valve on, check for LED error codes, clean flame sensor.
Short cyclingDirty filter, blocked vent, limit switchReplace filter, check vent pipes, verify proper airflow.
Blower won't stopThermostat fan settingCheck thermostat fan setting (should be AUTO, not ON).
Unusual noisesBlower, inducer motor, ductworkInspect blower wheel, check inducer motor, examine duct connections.
Error code flashingVarious system faultsCount LED flashes and refer to diagnostic chart in manual.

Reset: Turn power off for 30 seconds, then restore. If problem persists, call for service.
