BURNER COMPONENTS for 15”, 30” and 36”
Burner Head
- The component containing the burner ports where the gas/air mixture ignites. The burner ports are
distributed in a useful pattern to optimize heat transfer. The flames should be spread so they can be easily reached
by secondary air and provide a stable blue flame.
Venturi -
Threaded brass pipe that threads into the jet holder through the distribution rings which narrows and then
flares out again. This pipe helps maintain proper and constant primary air injection.
Inner Distribution Ring -
Routes the gas from the simmer orifice hood to the simmer port holes located on the
burner cap.
Outer distribution Ring -
Routes the gas from the main burner orifice hood to the main burner port holes on the top
of the burner head.
Jet Holder
- This component is mounted to the burner mounting bracket and to the burner box. The main burner
orifice is threaded into the jet holder as well as the venturi. It is the main support for the burner components.
Gas Orifice
- An opening or hole which regulates or limits the amount of gas flowing to a burner. Gas flow rate (vol-
ume) depends on the size of the orifice (hole) and the gas pressure at the inlet of the orifice.
