7.11 flat Roof Terminal Installation
Determine the point where the vertical air/flue duct and terminal
assembly will exit the roof.
• Fit the aluminium weather collar (2).
• Stick the flat roof penetration collar firmly into place with
adhesive in accordance with the codes of practice for flat
roofs (CP 144) to ensure a watertight seal.
• Working from above, insert the vertical roof duct (1) through
the flat roof collar and push it firmly into place.
• Vertically align the roof duct and attach it to the roof structure
with the fixing bracket (3) supplied.
• Fit the boiler hanging bracket and install the appliance
with reference to the installation and servicing instructions
supplied with the appliance.
7.12 flue Terminal cutting
DO NOT CUT THE FLUE TERMINAL should the clearances
above the appliance to the flue terminal not allow for
extensions.
7.13 fitting air/flue Duct extensions
With the flue terminal positioned in the roof, complete the
connection between terminal and adapter.
• Separate the flue duct from the terminal by twisting to
release from the securing catch inside the air/flue duct
• When cutting, cut equal amounts off the air duct and flue
duct.
• When joining extensions leave a gap of 5mm. between
each air duct this will leave a correct flue duct connection of
30mm.
noTe: For assembly reasons do not shorten any air duct to a
length of less than 80 mm. If necessary shorten two adjacent
extensions to achieve the overall required length.
noTe: See Fitting air/flue duct extensions / Fitting elbows for
further details on the installation of extensions and elbows.
• Push the sliding sleeve (6) firmly into place on the extension.
• Join the vertical roof duct (1) to the extension (4).
• Join the sliding sleeve (6) to the vertical flue adapter (5).
Using the sliding sleeve allows the appliance to be
easily removed and replaced without dismantling the
flue.
• Drill two holes 3mm Ø through the air duct of the flue/boiler
clamp at the most convienient holes on the air duct securing
clamp. (Ensure that the drill does not penetrate the inner
flue duct). Screw the air duct securing clamp to the air ducts
of the flue assembly and the vertical flue adapter using the
screws supplied.
• Ensure that any air duct securing clamps used are positioned
centrally and fixed to the air duct using the self tapping
screws supplied.
The air duct securing clamp MUST NOT be screwed
to the bottom of the vertical air/flue duct and terminal
accessory, this will allow for any slight movement in
the roof structure.
• Ensure that at least one fixing bracket supports the air/ flue
duct at each extension fitted.
7.14 fitting elbows
The elbows must be correctly aligned to avoid undue
stress on the joints and risk of leakage.
• The elbow fitted to the top of the boiler (1) should be twisted
by 3° to ensure that the second 87° elbow (2) exits the wall
perpendicular.
