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. A
template is provided on the appliance carton/box.
The center of the hole must be located anywhere
within the shaded area, unless extension kits are
used. See the dimensions diagram.
For weatherboard walls, drill through the center of
the weatherboard from the outside first and then
through the plasterboard.
