The top burner valves are mounted to the manifold pipe
and control gas flow to the orifice assembly.
The valves are mounted to the manifold pipe so that
the hole in the bottom of the valve is aligned with the
hole of the manifold. This allows gas to enter into the
valve. When the valve is in the off position the hollow
core, in the center of the valve, prevents gas from flow-
ing through the valve.
When the shaft of the valve is turned, the hole in the
side of the core moves over the hole in the case of the
valve. When the shaft is turn to the high position the
two holes are completely aligned and the maximum
amount of gas is allowed to flow through the valve.
As the shafted is rotated off a high position the holes
are misaligned and gas flow is reduced. When the shaft
is turned completely to the low position the two holes
are completely misaligned and gas is prevented from
flowing through that section of the valve. In the low
position the gas flow through the valve is through the
bypass orifice, located on the side of the valve.
The output of the valve is connected to the orifice as-
sembly by an aluminum tube.
The orifice, or hole, in the spud, serves two purposes;
first it controls the maximum amount of gas to the burner
and second it speeds the gas flow as it enters the burner
venturi.
