Installation Requirements

Professional installation recommended. Ensure proper clearances and venting.

Location requirements: Minimum 1-inch clearance from combustible materials, level surface.
Venting: Use approved PVC piping for intake and exhaust, proper slope for condensation drainage.
Gas connection: Use black iron pipe with drip leg, pressure test required.
Electrical: 120V AC dedicated circuit, proper grounding.
Ductwork: Properly sized and sealed return and supply ducts.

WARNING! Gas appliances can be dangerous; installation must comply with local codes and be performed by qualified technician.

Initial Setup & Commissioning

Professional startup procedure required for warranty validation.

Gas pressure adjustment: Set manifold pressure to 3.5" WC for natural gas.
Blower speed settings: Adjust dip switches for proper airflow (CFM).
Thermostat configuration: Connect compatible thermostat, set to heat mode.
System check: Verify ignition sequence, flame rectification, safety controls.
Combustion analysis: Measure flue gases for proper CO2 and O2 levels.

CAUTION! Only qualified HVAC technicians should perform startup procedures.

Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
Furnace won't start	Power, thermostat, door switch	Check circuit breaker, thermostat settings, ensure door closed properly.
No heat	Pilot/ignition, gas supply	Verify gas valve on, check igniter, flame sensor cleaning.
Short cycling	Filter, limit switch	Replace dirty filter, check for blocked vents/registers.
Blower not running	Motor, capacitor, control	Check blower motor, capacitor, control board signals.
Unusual noises	Motor, blower wheel	Inspect blower wheel for debris, motor bearings for wear.
Error codes flashing	Various system faults	Count LED flashes and refer to diagnostic chart in manual.

Reset Procedure: Turn thermostat to OFF, wait 30 seconds, return to HEAT.
