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, 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.

2. Push fit the vertical connector (supplied separately) into the
boiler flue connection and retain with the turret clamp and
securing screw (supplied with the boiler). ENSURING THE
GASKETS IN THE BOILER FLUE OUTLET ARE CORRECTLY
FITTED.
3. "Push" fit extension duct (if required (supplied separately)) into
vertical connector.
4. 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 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.
5. Finally ensure the roof flashing plate is correctly sealed to the roof.
