Air shutter adjustment

must only be done by a

qualified gas installer!

FIGURE 30

This unit is approved for use with a 2" liner for air intake

and a 3" liner for exhaust. For best performance, however,

it is recommended to use two 3" liners.

Air shutter settings will differ depending on the liner sys-

tem used. Use the charts below to determine the correct

air shutter setting:

Some vent configurations may display a very active flame. If

this appearance is not desirable, the vent exit may be re-

stricted using the restrictor plate shown in FIGURE 6b. Bend

the flap up as shown to reduce the velocity of the exhaust

gases, slowing down the flame pattern and creating a more

traditional appearance.

FIGURE 29

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.

HELPFUL HINT:

A mirror will let you see the opening of

the air shutter without removing the

burner. Scribe a line along the venturi

tube and air shutter cap. Open or close

according to the original opening by

using the scribed line as your datum.
