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. (Refer to No.
7 below)
Ensure the cut pipe ends are free from any burrs.
1. Ensure the flue seal collar B is located onto the flue
assembly A.
2. Position the roof flashing plate D (supplied separately) over
the hole cut in the roof and insert flue assembly A from the
roof end.
3. Remove the casing top blanking plate and gasket and refit to
the boiler rear flue hole.
4. Fit the boiler vertical conversion kit (to be found in the vertical
connector kit). Refer to Frame 26 No's 2 to 7.
5. Push fit the vertical connector E (supplied separately)
into the boiler flue connection and retain with the four
securing screws provided.
6. "Push" fit extension duct F (if required (supplied
separately)) and the roof flue kit assembly A into the
vertical connector E.
7. If the last extension duct requires cutting,
measure 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 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.
8. Slide down and position the flue seal collar B over
the roof plate D and secure it with the 3 screws C to
the flue assembly A.
9. Finally ensure the roof flashing plate D is correctly sealed to
the roof.
