More info

The choke regulates the amount of air that is mixed with the propane during combustion. Burner Nozzle – 304 Stainless steel stepped nozzle for greater efficiency and longer life. (Burner Nozzle diameter 33,7 mm) DFP burner Powerful and efficient, this next generation burner is pre-tuned to develop a neutral flame leaving little oxygen for scaling. Our nozzle design is longer lasting and increases the burner’s efficiency.

Forced burner reach 81.497 BTU out put on 25 PSI !!!


Graphic Explanation

ODC (orifice discharge coefficient) : gas jet will flow 68% of the gas that a perfect orifice would flow.

BTU/Hr-KW/H: burner power.

PSI – ATM: gas pressure from gas pressure regulator.
