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.
