When the gas leaves the orifice it passes through the
air shutter. The moment of the gas passing through
the air shutter creates a vacuum, which draws air into
the burner venturi, where the air and gas mix. For proper
combustion the ratio of this mixture should be ten parts
of air to one part of gas.
The mixture leaves the venturi and enters into the burner
tube. The threaded end of the burner tube extends
through the spill tray where the burner base is placed
over it. A brass ring is threaded down on the burner
tube to hold the burner base in place.
The burner ring is placed in the burner base. The slots
in the burner ring, when closed at the top by the burner
cap, form the burner ports.
The combustible mixture which comes up the burner
tube pressurizes the burner head, forcing the mixture
out of the burner ports. When the mixture is ignited a
sharp blue cones burns off the ports of the burner head.
