Installation Requirements

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

  1. Location: Install in approved location with proper clearances to combustible materials.
  2. Venting: Use approved PVC pipe for intake and exhaust; maintain proper slope and supports.
  3. Gas Connection: Use approved gas pipe and fittings; pressure test before operation.
  4. Electrical: Connect to proper voltage supply; install disconnect switch within sight.
  5. Drain Lines: Install condensate drain lines with proper trap and routing.

WARNING! Installation must be performed by qualified HVAC technician. Gas appliances can be hazardous if improperly installed.

First-Time Setup

Complete installation verification and initial startup procedure.

  1. Verify installation: Check all connections, clearances, and venting.
  2. Gas pressure: Set manifold pressure according to rating plate specifications.
  3. Electrical: Verify proper voltage and grounding.
  4. Startup: Follow lighting instructions; verify proper ignition sequence.
  5. Airflow: Set blower speeds for heating operation.
  6. Thermostat: Program heating schedule and temperature settings.

CAUTION! Do not operate furnace if smell of gas is present. Evacuate area and call gas company immediately.

Specifications

Controls and Settings

Access control board via front panel. LED status lights indicate system operation and fault codes.

Control Board: POWER switch, diagnostic LEDs, dip switch settings, terminal strip for thermostat connections.

Heating Settings: Temperature rise adjustment, blower speed settings, gas pressure adjustment. Safety: Pressure switch settings, flame sensor monitoring, limit switch operation. Diagnostics: LED flash codes for troubleshooting, manual test modes, reset procedures.

Connecting Thermostat

Compatible with conventional and programmable thermostats. Use 18-gauge thermostat wire.

  1. Turn off power to furnace at disconnect switch.
  2. Remove control board cover to access terminal strip.
  3. Connect thermostat wires: R (24V), W (heat), G (fan), C (common), Y (cooling if equipped).
  4. Secure connections and replace cover.
  5. Restore power and test thermostat operation.

Tip: Use programmable thermostat for maximum energy savings and comfort.

Operating Instructions

Normal heating operation and seasonal startup procedures.

  1. Thermostat Setting: Set thermostat to desired temperature and HEAT mode.
  2. Startup Sequence: Control board initiates pre-purge, igniter warm-up, gas valve opening.
  3. Flame Proving: Flame sensor confirms ignition; main burner operates.
  4. Blower Operation: Indoor blower starts after heat exchanger warm-up delay.
  5. Shutdown: Thermostat satisfied; gas valve closes; blower continues for post-purge.
  6. Seasonal Startup: Follow initial startup procedure after extended shutdown.

WARNING! Do not attempt to service gas components. Contact qualified technician for repairs.

Maintenance Procedures

Regular maintenance ensures optimal performance and safety.

  1. Monthly: Check and replace air filter as needed.
  2. Seasonal: Inspect vent pipes for obstructions or damage.
  3. Annual: Professional inspection and cleaning of burners, heat exchanger, and flue passages.
  4. Blower: Clean blower wheel and housing annually.
  5. Drain System: Clean condensate trap and drain lines.
  6. Electrical: Check all connections and component operation.

CAUTION! Turn off electrical power and gas supply before performing any maintenance.
