45 years of trusted expertiseOil, Gas Burner Spares & Nozzles
Engineered for precision combustion control and reliable appliance servicing, this range of oil and gas burner spares includes replacement nozzles, blast tubes, ignition electrodes, control boxes, and oil pump components. Built to withstand high thermal loads, these trade-grade spares help engineers maintain optimal fuel atomisation and burner efficiency across domestic and commercial heating systems.
Achieving clean, efficient combustion requires exact component specification, particularly during routine annual servicing or emergency burner repairs. A worn burner nozzle, fouled electrode, or deteriorating solenoid valve can lead to poor fuel atomisation, excessive soot buildup, elevated flue gas emissions, and unexpected lockout events. Our comprehensive selection of burner spares includes precision-calibrated oil nozzles featuring defined spray angles and pattern configurations, alongside replacement control boxes, phototells, flame sensors, drive dogs, and flexible fuel lines compatible with leading commercial and domestic pressure jet burners. By sourcing correct original manufacturer parts or matched trade equivalents, heating engineers can quickly restore correct air-to-fuel ratios, maintain seasonal fuel economy, and ensure full compliance with current OFTEC and gas safety performance standards.
Frequently Asked Questions
How do I choose the correct spray angle and spray pattern when replacing an oil burner nozzle?
Replacing an oil nozzle requires matching three essential parameters specified by the boiler or burner manufacturer: throughput capacity measured in gas per Hour (GPH), spray angle (typically 45, 60, or 80 degrees), and spray pattern type (solid, hollow, or semi-solid). The correct spray pattern ensures the atomised oil droplets align perfectly with the air pattern produced by the burner retention head and blast tube. Installing a nozzle with an incorrect spray angle or pattern can cause fuel impingement on the combustion chamber walls, leading to heavy carbon deposits, smoky combustion, and reduced boiler efficiency. Always refer to the burner data plate or manufacturer servicing manual to confirm exact nozzle specifications before fitting.
What causes an oil or gas burner control box to go into lockout mode?
A control box initiates safety lockout when it detects a breakdown in the ignition or flame-monitoring sequence. Common causes include a failed ignition electrode spark, a contaminated photocell or ionization probe that fails to signal flame presence, insufficient oil pump pressure, or a faulty fuel solenoid valve. Additionally, poor draft conditions or a blocked flue can trip air pressure switches, causing the control module to halt the firing sequence to prevent unburnt fuel from accumulating in the combustion chamber. Systematically testing fuel supply pressure, electrical continuity, and flame sensor resistance helps identify whether the issue stems from an external component or an internal failure within the control box itself.
When should oil burner flexible hoses and fuel pump solenoids be replaced?
Flexible oil lines and solenoid coils undergo continuous thermal cycling and chemical exposure, making them subject to gradual degradation over time. Industry guidelines recommend replacing flexible rubber oil lines during routine servicing or every two to three years, as aging inner linings can crack, leak, or shed debris into the oil pump strainer and burner nozzle. Solenoid coils and valves should be inspected for thermal cracking or coil degradation if the burner experiences intermittent flame failure or fails to shut off fuel supply cleanly when the call for heat ends. Replacing worn fuel lines and solenoids during preventive maintenance prevents emergency call backs and protects internal pump seals.
