Drilling Flue Hole

Ensure that there are no gas or water lines, or electrical circuits in the wall location where the flue hole is to be drilled. Drill the flue hole using a 3 1/8 inch (80

mm)drill. The center of the hole must be located exactly at the specified point.

See diagram. For weatherboard walls, drill through the center of the weatherboard from the outside first and then through the plasterboard. A template is provided.

For installation without using extension kits, the configuration of the flue manifold, air intake hose, and exhaust slide pipe should be as shown when installation is completed. The 60 degree arc shows where the flue manifold can be located.
