Features at a Glance

Key components: Stainless steel heat exchanger, variable-speed ECM blower motor, electronic control board, pressure switches, gas valve, igniter, flame sensor, condensate drain system.

Installation Requirements

Unpack and inspect all components. Ensure proper clearances and location requirements.

1. Location: Install in approved locations with proper clearances (1-inch from combustible materials).
2. Venting: Install PVC vent pipes according to local codes and manufacturer specifications.
3. Gas Connection: Use approved gas piping materials; pressure test before operation.
4. Electrical: Connect to 120V AC power supply with proper grounding.
5. Thermostat: Connect standard 24V thermostat wiring (R, W, G, Y, C terminals).

WARNING! Installation must be performed by qualified HVAC technician. Gas furnaces can produce carbon monoxide - ensure proper venting.

First-Time Setup

Complete installation verification before initial startup.

1. Gas pressure check: Verify inlet and manifold gas pressures are within specifications.
2. Venting verification: Confirm proper draft and combustion air supply.
3. Electrical checks: Verify proper voltage and grounding.
4. Initial startup: Turn on power and gas supply; observe ignition sequence.
5. System check: Verify proper heating operation and temperature rise.

CAUTION! Never bypass safety controls. Always verify proper operation before leaving installation.

Controls and Operation

Integrated control board manages all furnace operations with diagnostic capabilities.

Control Board: LED status light indicates system operation and fault codes. DIP switches for blower speed and configuration settings.

Operation Sequence: Call for heat from thermostat → Inducer motor starts → Pressure switch verification → Hot surface igniter activates → Gas valve opens → Flame sensor verification → Main blower starts → Heating cycle continues until thermostat satisfied.

Thermostat Settings: Compatible with standard 24V thermostats; programmable thermostats recommended for maximum efficiency.

Venting and Combustion Air

Direct vent system using PVC pipe for both intake and exhaust.

1. Vent Pipe: Use schedule 40 PVC, CPVC, or ABS pipe approved for furnace venting.
2. Termination: Maintain proper clearances from windows, doors, and air intakes.
3. Slope: Vent pipes must slope downward toward furnace for condensate drainage.
4. Combustion Air: Ensure adequate fresh air supply for proper combustion.

Tip: Always follow local building codes and manufacturer specifications for venting installations.

Maintenance Procedures

Regular maintenance ensures optimal performance and longevity.

1. Monthly: Check and replace air filter as needed.
2. Annual: Professional inspection and cleaning recommended.
3. Blower Assembly: Clean blower wheel and housing annually.
4. Heat Exchanger: Visual inspection for cracks or damage.
5. Condensate System: Clean drain trap and verify proper drainage.
6. Venting: Inspect vent pipes for obstructions or damage.
7. Electrical: Check all connections and component operation.
8. Gas System: Verify proper gas pressure and valve operation.

WARNING! Turn off electrical power and gas supply before performing any maintenance. Only qualified technicians should service gas components.

Safety Features

Multiple safety systems protect against hazardous conditions. Flame rollout switch: Detects improper burner operation. Limit switches: Prevent overheating. Pressure switches: Verify proper venting. Flame sensor: Confirms burner ignition. Ignition control: Safe start-up sequence.

Care & Cleaning

Keep furnace area clean and free of combustible materials. Use vacuum with soft brush attachment for cleaning exterior surfaces.

CAUTION! Never use water or liquid cleaners on electrical components. Keep ventilation openings clear of obstructions.
