Coleman Oil Furnace Manual

The Coleman Oil Furnace is a high-efficiency heating system designed for residential use, featuring advanced combustion technology, reliable oil-fired operation, built-in safety controls, thermostat compatibility, and energy-saving modes. Below are key sections for safety, features, installation, setup, operation, maintenance, and troubleshooting.

Features at a Glance

Key components: Oil burner assembly, heat exchanger, combustion chamber, blower motor, safety controls, thermostat connections, oil filter, and ignition system.

Installation

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

1. Position furnace: Place on stable, level surface with proper clearances (minimum 18 inches from combustible materials).
2. Connect oil supply: Install oil line with shutoff valve; ensure proper filtration.
3. Connect venting: Install flue pipe according to local codes with proper draft.
4. Electrical connections: Connect to dedicated 120V circuit; ground properly.
5. Thermostat wiring: Connect 24V thermostat wires to control board.

WARNING! Installation must be performed by qualified technician. Improper installation can cause fire hazard or carbon monoxide poisoning.

First-Time Setup

Power on furnace; follow startup sequence.

1. Purge air from oil line: Open bleed valve until steady oil flow appears.
2. Set thermostat: Turn thermostat to desired temperature above current room temp.
3. Initial ignition: System will attempt ignition; may take several cycles to purge air.
4. Adjust burner: Qualified technician should set combustion for optimal efficiency.
5. Test safety controls: Verify all safety functions operate correctly.

CAUTION! First startup must be performed by qualified service technician. Ensure proper ventilation and carbon monoxide detectors installed.

Connecting Thermostat

Standard 24V thermostat connection with R, W, G, C terminals.

1. Turn off furnace power at main disconnect.
2. Remove thermostat cover and connect wires: R (24V), W (heat), G (fan), C (common).
3. Secure wires and replace cover.
4. Restore power and test operation.

Tip: Use 18-gauge thermostat wire for runs over 50 feet. Ensure proper polarity for C wire.

Operating Procedures

Normal heating operation controlled by thermostat.

1. Set thermostat: Move selector to HEAT position, set desired temperature.
2. Startup sequence: Thermostat calls for heat, control board initiates pre-purge, ignition, and burner operation.
3. Fan operation: Blower starts after heat exchanger reaches temperature (fan delay).
4. Shutdown: Thermostat satisfied, burner shuts off, blower continues for post-purge cooling.
5. Emergency shutdown: Use main power switch or thermostat OFF position.

WARNING! Never bypass safety controls. If furnace locks out repeatedly, call qualified technician.

Maintenance Schedule

Annual professional maintenance required. Monthly homeowner checks recommended.

Care & Cleaning

Turn off power before any cleaning. Regular maintenance ensures efficiency and safety.

Air Filter: Replace every 1-3 months during heating season. Combustion Chamber: Professional cleaning annually. Blower: Vacuum dust annually. Venting: Inspect for blockages seasonally.

CAUTION! Never use water or chemical cleaners on electrical components. Wear protective equipment when handling oil or combustion residues.
