TABLE 8.7
VERTICAL TWIN PIPE FLUE KIT AND COMPONENTS LBF81/121
1.
Determine the desired location for the flue terminal and air intake, taking into account minimum
distances as detailed in
Figure 8.1
,
Table 8.1
and the relevant British Standards.
2.
Taking care to protect the appliance from debris and dust, drill both holes in the desired location. The
diameter of the holes should be no more than 10mm greater than the diameter of both the air supply
and outlet pipes.
NOTE:
The holes should be drilled from the outside to ensure that no damage is done to the roofing material.
Extra care should be taken to ensure that the hole is drilled vertically.
3.
Install the roof flashing and secure as appropriate.
4.
Carefully insert the roof terminals (items 3&7 in
Figure 8.7)
through the roof flashings. Fit the terminal
end caps secure using appropriate fixings (items 8&9 in
Figure 8.7)
NOTE:
When inserting the roof terminals do not support or turn the terminals using the caps.
5.
Ensure the terminal is vertical using a spirit level.
6.
Measure, cut accordingly and fit the 38mm flue length (item 5 in
Figure 8.7)
to the flue hood assembly
using the 38mm gasket and clamp provided.
7.
Slide the 60mm/38mm concentric adaptor (item 2 in
Figure 8.7)
over the 38mm pipe and push fit onto
the flue hood.
8.
Fit the 38mm 90° bend (item 6 in
Figure 8.7)
onto the 38mm flue length, secure the elbow by using the
38mm gaskets and clamps provided.
9.
If additional lengths of flue pipe are required to connect to the terminals these should be measured, cut
accordingly and fitted. If no additional components are required fit the flue lengths to the 38mm elbow
and the 60mm connection on the concentric adaptor.
10.
With all components in position, tighten any support brackets used.
