Sealing ‘through roof’ and ‘through wall’ penetrations:
For ‘through roof’ penetrations, use a
Deck-tite flashing or equivalent to create a weather-
tight seal between the flue and the roof cladding.
For ‘through wall’ penetrations, this will require the use of a Wall Thimble. The Wall Thimble
will ensure you have suitable clearance from combustibles as well as sealing the
penetration. The section of the wall thimble installed on the external surface of the wall
should be sealed to the wall using a high temperature sealant such as a High Temperature
RTV Silicone or equivalent. Additional sealant is required to seal the Terminal Cap to the
external wall. A bead should be run along the edge of the Terminal that will be in contact
with the wall once installed.

Twist locking procedure:
Before connecting flue components, to ensure an airtight seal run a single 7-8mm bead of
High Temperature RTV Silicone
or equivalent, on the ‘male’ end of the flue as shown in the
diagram below.
The four indentations located on the female end of the flue are designed to slide straight
onto the male ends of the adjacent flue length, by orienting the four flue indentations so
they match and slide into the four entry slots on the male ends.
Push the pipe sections completely together, then twist-lock one section clockwise
approximately one-quarter turn, until the two sections are fully locked.
Wipe off any excess sealant from the exterior of the flue joint.
