6.4.1 Connecting the Flue/Chimney
HORIZONTAL TELESCOPIC FLUE (concentric 60/100)
1. There are two telescopic sections, the terminal assembly and
the connection assembly, a roll of sealing tape and two self
tapping screws. A 93° elbow is also supplied.
2. The two sections can be adjusted to provide a length between
315mm and 500mm (Fig. 24) when measured from the flue elbow
(there is 40mm engagement into the elbow).
3. Locate the flue elbow on the adaptor at the top of the boiler.
Set the elbow to the required orientation (Fig. 25).
The flue elbow is angled at 93 degrees to ensure a fall
back to the boiler.
4. Measure the distance from the outside wall face to the elbow.
This dimension will be known as ‘X’ (Fig. 25).
5. If the distance from the flue elbow to the outside face of the
wall (‘X’ in Fig. 25) is less than 250mm the connection assembly
can be discarded and the terminal assembly fitted directly into the
elbow.
6. In instances where the dimension ‘X’ (Fig. 25) is between
250mm and 315mm it will be necessary to shorten the terminal
assembly by careful cutting to accommodate walls of these
thicknesses.
7. To dimension ‘X’ add 40mm. This dimension to be known as
‘Y’.
8. Adjust the two telescopic sections to dimension ‘Y’ and seal the
joint with the tape provided (Fig. 27). Ensure that the labels
marked ‘TOP’ on the terminal and connection assemblies are
uppermost.
9. Using the clearance holes in the connection assembly secure
it to the terminal assembly using the screws supplied with the
telescopic flue (Fig. 28).
