24 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. 6 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. Push fit the vertical connector E (supplied seperately) into the
boiler flue connection and retain with the retention flange F
(supplied with the boiler) and securing screw. ENSURING
THE GASKETS IN THE BOILER FLUE OUTLET ARE
CORRECTLY FITTED.
4. "Push" fit the 60/100 to 80/125 adaptor G (supplied
separately) into the vertical connector.
5. "Push" fit extension duct H (if required (supplied separately))
and the roof flue kit assembly A into the adaptor G.
6. 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.
7. 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.
8. Finally ensure the roof flashing plate D is
correctly sealed to the roof.
