Fuel Nozzles
The fuel nozzles are located at the front of the burner gun assembly. The nozzles are installed into a brass
block. There is a 10.5 GPH nozzle and a 19.5 GPH nozzle. The 10.5 GPH (Gallons Per Hour) nozzle sprays fuel on
low fire, and both nozzles spray fuel on high fire.
Disassemble the nozzles with a 5/8” wrench and a 5/32” Allen wrench. Clogged or faulty nozzles can contribute
to a number of faults. It is important to perform the 250-hour maintenance to remove and clean the nozzles to
keep the burner running properly.
