Always follow proper safety procedures when servicing oil furnace equipment.
WARNING! Oil furnaces operate at high temperatures and use combustible fuel. Always follow manufacturer safety guidelines and local codes.
Proper installation ensures safe and efficient operation.
CAUTION! Installation must comply with NFPA 31, local building codes, and manufacturer specifications.
Primary control manages burner operation and safety functions.
Primary Control: Manages burner sequence, includes safety lockout, cad cell flame detection, and timing functions.
Limit Controls: High limit control prevents overheating, fan control regulates blower operation. Safety Devices: Rollout switch protects against flame rollout, pressure switch verifies draft, cad cell confirms flame presence. Wiring: Follow wiring diagram exactly; verify all connections are secure and properly terminated.
Proper venting is critical for safe operation and efficiency.
Tip: Always perform combustion analysis and draft test after installation or service.
Proper startup procedure ensures optimal performance and safety.
WARNING! Never bypass safety controls during startup. Always verify proper operation of all safety devices.
Regular maintenance ensures efficiency, reliability, and safety.
CAUTION! Always disconnect power and fuel supply before performing maintenance.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| No ignition | No fuel, ignition failure | Check oil supply, bleed line, verify ignition transformer, check electrodes |
| Short cycling | Dirty filter, limit switch | Replace filter, check airflow, verify limit control operation |
| Excessive smoke | Poor combustion | Clean combustion chamber, adjust air band, replace nozzle |
| Lockout condition | Safety control tripped | Reset primary control, identify cause (flame failure, rollout, etc.) |
| No heat output | Blower failure | Check motor, capacitor, fan control, wiring |
| Unusual noises | Mechanical issues | Inspect blower wheel, motor bearings, combustion air |
Reset Procedure: Press reset button on primary control; if lockout persists, identify and correct underlying issue.
