Burner Components (Refer to
Figure 3-1
):
Burner Cap
- Provides the upper portion of the ports required to create a combustible mix and proper flame quality
of the burner and the decorative top for the burner with a black porcelain coating.
Burner -
Contains 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. The burner also incorporates the Inner Distribution Ring, which Routes the gas from the
simmer orifice to the simmer port holes, and the Outer Distribution Ring, which routes the gas from the main burner
orifice to the main burner port holes.
Venturi
- Helps maintain proper and constant primary air injection.
Electrode -
The Electrode supplies the spark to ignite the burner. The electrode senses the flame, once the burner
is ignited and will stop sparking. If no flame is sensed, and the valve is opened, the electrode will start sparking to
re-ignite the flame. This is part of the auto-reignition system.
Orifice Holder
- This component is mounted to the burner mounting bracket and to the burner box. The Simmer
and Main orifice is threaded into the orifice holder and routes the gas to the appropriate ports of the burner. It is the
main support for the burner components.
Simmer Orifice and Main Orifice
- An opening or hole which regulates or limits the amount of gas flowing to a
burner. Gas flow rate (volume) depends on the size of the orifice (hole) and the gas pressure at the inlet of the ori-
fice.
