Oil Burners - Beckett Model AFG Oil Burner

Beckett Model AFG Oil Burner

Specifications:
0.75 to 2.00 gallons per hour 56,000 to 420,000 BTU/hr input Fuels
No. 1 or No. 2 Heating Oil (ASTM D396) only
Dimensions (standard)
Height: 11-1/2"
Width: 12-7/8"
Depth: 6-9/16" (chassis only)
Electrical Characteristics
Motor: 3450 RPM, NEMA M-Flange, manual reset overload protection Power Supply: 120 V./60 Hz./1 phase
Ignition: 10,000 V. 23 ma. secondary, continuous duty shielded transformer
Operating Load: 5.8 amps (maximum)
Fuel Unit Single Stage Or Two Stage
Special Features
The model AFG oil burner builds on the time tested design of the popular AF burner. The AFG adds an Air Turbo Injector and
a high efficiency blower wheel to the field-proven basic AF burner. Inside the burner housing, the specially designed Air Turbo
Injector channels combustion air for extra smooth starts and minimal pulsation to enhance operating efficiency and minimize
air noise.
The high efficiency blower wheel interacts with the Air Turbo Injector to create high static pressure firing under any draft
condition. This capability makes the AFG the ideal choice for firing positive pressure heating appliances and for overcoming
poor chimney design conditions. The firing range of this versatile burner is 0.75 to 2.00 gallons per hour.
The AFG accepts Beckett’s standard flame retention heads, air tube combinations, pedestals, flanges and other accessory
parts. The air tube combinations feature second stage air introduction to complete and optimize combustion, and a unique
design that allows the installer to make precise adjustments. The result is a clean, compact flame and peak burner
performance.
