As of March 2015, the Beckett gas burner suitable for residential use is model CG4, equipped with the GeniSys 7590 advanced gas burner control, fixed-head combustion and easy access for maintenance and propane conversion. The CG4 uses natural gas with 0.64 specific gravity and LP gas with 1.53 specific gravity.
The Beckett CG4 unit design also includes a 24-volt gas valve with a 3.5-inch manifold, direct spark ignition and a removable gas gun assembly for easy servicing. The gas burner is powered by a 120-volt, 1/7-horsepower motor.
With the advent of energy-efficient home appliances and improved insulation in modern construction, demand developed for advanced technology and improved performance in gas burners, and Beckett designed the CG4 to meet those household needs.
