1. Firing rates are based on a 3.5″ WC manifold gas pressure and use of the appropriate orifice for the fuel being fired.
2. Air tube assemblies are provided with a full selection of the natural gas orifices appropriate to the burner head.
3. LP orifices are provided in kits containing all the LP orifices for the burner head size. Kit P/N 52309-004 is for use with the F3G head, 52309-005 is for the F4G and 52309-006 is for the F6G. The installer is responsible for selecting and installing the appropriate orifice for the applications.
4 .Burner heads and nozzles are identified with the markings shown to assure the use of compatible combinations.
5. Burner chassis are built for the highest rate configuration. The installer is responsible to add the baffle and/or change the band as required for the application.
6. Initial settings are intended for use only as a starting point for burner adjustments. They cannot make provision for all installation possibilities. It is important that you adjust your burner to your installation requirements using properly calibrated flue gas analysis instruments.
Our heavy duty 16-gauge steel control boxes can be mounted on any of our commercial CF & CG Series burners. They come in 2 convenient sizes (12″ x 12″, 16″ x 12″) according to your burner needs. We have a variety of light indicators, voltage configurations, and other options to chose from.
Please note, all warranty claims must be initiated through an authorized Beckett supplier/distributor. Distribution policies will not allow Beckett to directly handle warranty claims with installers and/or consumers.
