2.15 ASSEMBLING THE ROOF FLUE KIT

Determine the correct height that the flue should terminate above
the roof. If after calculating or measuring the overall flue height
from the top of the boiler, it is necessary to cut both pipes of
assembly A, then ensure they are cut equally leaving the inner
flue tube longer than the outer air tube as supplied.
Ensure the cut pipe ends are free from any burrs.
1. Position the roof flashing plate (supplied separately) over the
hole cut in the roof and insert flue terminal from the roof end.

6. If the last extension duct requires cutting, measure 'X', the distance
(outer ducts), between the duct and the terminal and add 100 mm to this
dimension. This gives the length of the last extension duct.

Note. Check the position of the inner flue duct relative to the outer duct on
'X'
the assembled extension duct(s) and ensure the terminal flue duct is cut
longer than the air duct to ensure engagement in the final flue duct seal.
7. Finally ensure the roof flashing plate is correctly sealed to the roof.
2. Fit the vertical connector (supplied in kit) in accordance with the
instructions provided with the vertical connector kit.
3. Secure the vertical connector by applying downward pressure
on the connector.
4. Position the clamp on the top face of the flue manifold and push
it horizontally backwards. Locate both clamp lugs into the flue
manifold and secure to the flue manifold with the M5 retaining
screw.
5. Push extension duct (if required (supplied separately)) into
vertical connector.
Note. Ensure turret sample points are servicable and all caps and
plugs are fitted. Fill the condense trap/siphon with water.
