Wall penetration
Direct flue wall penetration requirements
Use the guide pictured to mark the penetration points for the gas supply and flue transition locations.
Consideration must be given to the position of any studs, noggins or other components of the wall
structure on both sides of the wall. Mark these measurements accurately as this is critical to a successful
installation.
The penetration for the flue transition only needs to be made for direct flue installations, where the
terminal is directly to the rear of the appliance. If no flue pipe penetration is required the markings are
still useful for indicating the correct position of the flue transition within the enclosure for other flue
applications.
For weatherboard walls, drill through the centre of the weatherboard from the outside, then drill from
the inside through the plaster board.
