Features at a Glance

Key components: High-efficiency combustion chamber, oil burner assembly, heat exchanger, blower motor, thermostat connections, safety controls, and flue vent.

Installation Guidelines

Proper installation is critical for safe and efficient operation. Follow all local codes and manufacturer specifications.

1. Location Selection: Install in well-ventilated area with clearances per manual specifications.
2. Venting System: Install Type L vent pipe with proper slope and termination.
3. Oil Supply: Connect to oil tank with copper tubing and proper filters.
4. Electrical Wiring: Connect to dedicated 120V circuit with proper grounding.
5. Thermostat Wiring: Connect low-voltage thermostat wires to control board.

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

First-Time Setup

Initial startup and commissioning procedures for new installations.

1. System Check: Verify all connections are secure and proper clearances maintained.
2. Oil Line Purge: Bleed air from oil lines using purge valve on fuel unit.
3. Combustion Adjustment: Set air band and draft regulator for optimal smoke reading.
4. Thermostat Setup: Program thermostat for desired temperature settings.
5. Safety Test: Verify all safety controls function properly.

CAUTION! Never bypass safety controls. Test carbon monoxide detectors before occupancy.

Controls and Settings

Primary control system with safety limits and operational adjustments.

Primary Control: Power switch, reset button, safety lockout indicator.

Temperature Settings: High limit control adjustment, fan control settings (on/off temperatures). Combustion Settings: Air band adjustment, draft regulator setting, nozzle size selection. Operational Modes: Continuous fan, auto fan, burner operation cycles. Safety Settings: High limit switch, flame rollout switch, stack temperature sensor.

System Connections

Proper connection of oil supply, electrical, venting, and control systems.

1. Oil Supply: Connect with copper tubing, install oil filter and shutoff valve.
2. Electrical: Connect line voltage and low-voltage thermostat wires.
3. Venting: Install approved vent pipe with proper clearances.
4. Air Supply: Ensure adequate combustion air supply.
5. Thermostat: Connect compatible 24V heating thermostat.

Tip: Use pipe dope on all oil line connections. Never use Teflon tape on oil fittings.

Operation Procedures

Normal operating procedures and seasonal startup/shutdown.

1. Startup: Thermostat calls for heat, primary control energizes ignition system.
2. Pre-purge: Blower operates for 30-60 seconds before ignition.
3. Ignition: Transformer energizes, electrodes spark, oil valve opens.
4. Burn: Combustion occurs, heat exchanger warms, blower circulates air.
5. Shutdown: Thermostat satisfied, oil valve closes, post-purge cycle.
6. Seasonal Startup: Check oil filter, nozzle, electrodes, and safety controls.
7. Seasonal Shutdown: Clean heat exchanger, service oil filter, cover unit.

WARNING! Never operate with blocked vent or flue. Monitor for unusual noises or odors.

Safety Features

Multiple safety systems protect against hazardous conditions. Stack temperature sensor monitors flue gas temperature. Flame rollout switch detects improper burner flame. High limit switch prevents overheating. Primary control includes safety lockout after multiple ignition attempts.

Maintenance & Cleaning

Regular maintenance ensures efficient and safe operation. Annual professional service recommended.

Annual Maintenance: Replace oil filter and nozzle, clean heat exchanger, check electrodes, test safety controls, measure combustion efficiency.

CAUTION! Always disconnect power before servicing. Wear appropriate PPE during maintenance.
