OXYGEN INTAKE ADJUSTMENT
The Venturi is factory set with a set screw.
Before operation, check to see that the Ven-
turi is set in the position to the left.
The positioning keeps the flame looking
yellow and natural. The more oxygen you
let in, the smaller and bluer the flame, If the
oxygen is shut off completely, the flame will
contain more soot and unburned contami-
nents.
