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.

Air Tube Combination Chart

To Determine Air Tube Length

The Air tube Length (Dimension A) is the distance from the front of the burner housing to the end of the air tube.

No. 5685 Pedestal Kit – For conversion applications where no mounting flange is required.
No. 5606 Pedestal Kit Extended – Provides elevation from 8¼” to 13″.
