Installation Requirements

Professional installation recommended. Ensure proper clearances and ventilation.

Location: Install in well-ventilated area with proper clearances (minimum 18 inches from combustible materials).
Venting: Use approved chimney or vent pipe; maintain proper draft.
Oil Supply: Install oil tank with proper filtration; use #2 heating oil.
Electrical: Connect to dedicated 120V circuit with proper grounding.
Thermostat: Install compatible 24V thermostat with heat anticipator.

WARNING! Installation must comply with local codes and regulations. Use qualified HVAC technician.

Initial Setup & Startup

Professional startup procedure required for optimal performance.

System Check: Verify all connections, oil supply, and electrical power.
Venting: Check draft and ensure proper chimney condition.
Oil System: Prime oil line; check for leaks; set pump pressure.
Combustion: Adjust air shutter for proper flame pattern; measure stack temperature.
Thermostat: Set temperature differential and cycle rate.
Test Run: Start system and verify proper operation through complete cycle.

CAUTION! Never bypass safety controls. Keep flammable materials away from furnace.

Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
No heat	Power loss, thermostat, safety lockout	Check power, thermostat setting, reset button, check for lockout condition
Furnace short cycles	Dirty filter, high limit, airflow restriction	Replace filter, check limit switch, verify ductwork clear
Burner won't ignite	No fuel, ignition failure, pump issue	Check oil supply, inspect electrodes, verify pump pressure
Excessive smoke	Poor combustion, dirty nozzle, draft problem	Adjust air shutter, replace nozzle, check chimney draft
Unusual noises	Blower issues, pump cavitation, loose parts	Inspect blower assembly, check oil line, tighten components
Yellow flame	Insufficient combustion air	Adjust air shutter, check for blockages in air intake
Oil odor	Leaks, incomplete combustion	Inspect oil lines, check combustion efficiency

Reset Procedure: Press reset button once; wait 5 minutes before second attempt if needed.
