2. Assemble and Adjust the Sleeve Length

Measure wall thickness through previously drilled
3 1/2 inch (90 mm) hole.

The end of the sleeve should protrude 3/16 - 3/8
inch (5-10 mm) from the outside wall.

In the “A” vent kit there are 4 parts provided with
which to assemble the sleeve. Use the table to
determine which pieces to assemble.

In both the “A” and “B” vent kits, two parts are
threaded for additional adjustment.

Adjust the sleeve length to wall thickness plus
3/16 - 3/8 inch (5-10 mm).

outer terminal pull and release the two
internal ties and then pull out the outer
terminal.

Clearance to combustibles for the sleeve and
flanges is zero inches.

cables. Use the template supplied to mark the wall
locations for the flue manifold and the gas supply.
Drill the flue hole using a 3 1/2 inch (90 mm) drill.

For weatherboard walls, drill through the center of the
weatherboard from the outside first and then through
