Performance Capabilities

Nozzle Line Electrode Assembly – Self-centering, delivers oil to the nozzle, high voltage electricity to the electrodes; static plate controls and evens out air flow to the head for smooth, efficient combustion.

Flame Retention Head – One-piece flame retention burner head. Highly stable and intense combustion increases efficiency by as much as 35%.

Drive Motor – Continuous duty, permanent split capacitor, built for daily hard use and years of trouble-free operation. Overload protection included.

Ignition Transformer – 10,000 V/23 mA secondary positively and smoothly ignites fuel. Electrically balanced and shielded. No TV interference. Designed for heavy duty continuous operation.

Connector Tube Fitting – Special Beckett, high quality flare fitting.

Burner Housing – Sturdy die cast, precisely machined aluminum housing aligns pump and motor for smoothest operation and longest coupling life.
