Closing the air shutter will cause a more yellow flame, but
can lead to carboning. Opening the air shutter will cause a
more blue flame, but can cause flame lifting from the burner
ports. The flame may not appear yellow immediately; allow
15 to 30 minutes for the final flame colour to be estab-
lished.
Some vent configurations may display a very active flame.
If this appearance is not desirable, the vent exit may be
restricted using the restrictor plate shown in FIGURE 24.
