Horizontal Terminal Installation
With due consideration to terminal clearances mentioned in
Section 3.2 drill the one or two holes as required with a 90mm
core drill.
Push the horizontal terminal through the wall allowing approx.
100mm to protrude outside.
Push a grey rubber wall seal onto either side of the wall ensur-
ing that both wall seals are pushed up to the wall surface, see
examples (b) and (c) diagram 9.25.
Vertical Terminal Installation
With due consideration to terminal clearances mentioned in
Section 3.2, project the rise of the fl ue pipe to roof level and cut
150mm hole in the roof.
(a) Pitched Roof
Fit the required pitched roof weather collar over the 150mm
hole in the roof. Make good the tiling or slating around the col-
lar incorporating the fl ashing of the weather collar. Position the
angle cap over the weather collar in the correct orientation to
attain the correct angle for your roof. One way round gives a
pitch of 25°-38° and the other gives 37°- 50°.
(b) Flat Roof
Fit the aluminium weather collar over the 150mm hole in the
roof ensuring a weather tight seal.
Horizontal Pipes-Completion of Installation
Having built the pipe(s) from the boiler to the terminal(s), the
length of the fi nal pipe piece can be determined. Cut pipes at
the opposite end to the ‘O’ ring seal making square and free
from burrs. Push the horizontal terminal through the wall to en-
gage the fi nal pipe piece and pull back ensuring the grey wall
seals are fully pulled up to the outside and inside wall faces.
Vertical Pipes-Completion of Installation
Refer to diagram 9.25.
For installation of (a), attach the twin pipe to concentric fl ue
adaptor, part number A2011600, to the base of vertical terminal
assembly. For installation of (b), attach the single pipe to con-
centric adaptor, part number A2011500, to the base of vertical
terminal assembly.
With the vertical terminal assembly positioned in the roof, the
length of the fi nal pipe can be determined. Cut the fl ue to the
desired length measuring from the ‘O’ ring seal end and discard
the plain end of the tube. The cut end should be square and
free from burrs. Carefully push the terminal assembly upwards
to allow room for fi tting the fi nal fl ue piece(s). Fit a 100mm fi x-
ing bracket to the terminal assembly Part No2000460486. Pull
the terminal assembly down and join to the fl ue system. Ensure
that the terminal is making a weather tight seal on the weather
collar. Secure the fi xing bracket fi tted to the terminal to the roof-
ing struts or a purpose made batton.
