Installation

Unpack and inspect all components. Ensure proper location with adequate clearance.

1. Position furnace: Place on level surface with minimum 18-inch clearance on all sides.
2. Connect fuel line: Install oil supply line from tank to furnace pump.
3. Install venting: Connect flue pipe to chimney or direct vent system.
4. Electrical connection: Wire to dedicated 120V circuit with proper grounding.
5. Connect thermostat: Install compatible thermostat following wiring diagram.

WARNING! Installation must be performed by qualified technician. Ensure proper ventilation and fuel line integrity.

First-Time Setup

Complete installation checks before initial startup.

1. Fill oil line: Prime pump and bleed air from fuel system.
2. Check electrical: Verify proper voltage and grounding.
3. Test ignition: Activate system and observe startup sequence.
4. Adjust settings: Set thermostat parameters and operating temperatures.
5. Verify safety: Confirm all safety controls are functioning properly.

CAUTION! Never bypass safety controls. Test carbon monoxide detector before operation.

Controls and Settings

Access control panel via front cover. Primary controls: Power switch, thermostat, reset button, diagnostic lights.

Thermostat Settings: Temperature setpoint, cycle rate, fan control, system mode (heat/off).

Burner Controls: Ignition timing, fuel pressure, air adjustment, nozzle selection. Safety: High limit control, pressure switch, flame sensor, rollout switch. Maintenance: Filter status indicator, service reminder, lockout reset.

Connecting Components

Fuel System: Oil tank to pump connection. Electrical: Main power, thermostat wiring. Venting: Flue pipe to chimney.

1. Turn off power and fuel supply before making connections.
2. Use proper fittings and sealants for oil lines.
3. Ensure vent pipe slopes upward toward chimney.
4. Verify thermostat wiring matches terminal designations.

Tip: Label all wires and pipes for future service reference.

Operating Procedures

Normal heating operation with automatic cycle control.

1. Startup: Thermostat calls for heat, ignition sequence begins.
2. Pre-purge: Blower operates to clear combustion chamber.
3. Ignition: Transformer energizes, spark ignites oil mist.
4. Run: Burner operates until thermostat satisfied.
5. Shutdown: Fuel valve closes, post-purge clears chamber.
6. Emergency stop: Use red emergency switch if needed.
7. Seasonal shutdown: Follow proper procedure for extended non-use.

WARNING! Never attempt to manually ignite burner. Keep combustible materials away from furnace.

Safety Features

Multiple safety systems: High limit switch, flame rollout switch, pressure switch, blocked vent safety, oil pressure monitor. Automatic shutdown if any safety device activates.

Maintenance & Cleaning

Annual professional maintenance recommended. Monthly filter inspection. Keep area clean and unobstructed.

1. Monthly: Check air filter, clean if dirty.
2. Seasonal: Inspect nozzle, electrodes, pump strainer.
3. Annual: Professional tune-up including combustion analysis.
4. As needed: Clean heat exchanger surfaces.

CAUTION! Always disconnect power before servicing. Use only approved replacement parts.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No heat	Power outage, thermostat setting, safety lockout	Check power, verify thermostat above room temp, reset if locked out.
Furnace locks out	Dirty filter, faulty sensor, fuel issue	Replace filter, check flame sensor, verify fuel supply.
Unusual noises	Air in line, pump issues, motor bearing	Bleed fuel line, check pump pressure, lubricate if needed.
Poor heating	Dirty nozzle, incorrect pressure, airflow	Replace nozzle, adjust pressure, check blower operation.
Fuel odor	Leak in fuel line, improper combustion	Inspect all connections, check combustion efficiency.

Reset Procedure: Press reset button once only. If problem persists, call technician.
