3.7.11. Installation into timber framed buildings
Note: Installation must be in
accordance with the current
edition of Gas Engineers
Publication IGE/UP/7 (Gas
installations in Timber Framed
Housing).
Note: Prior to cutting any holes
within the inner wall for the
firebox or the flue duct (plus
clearance dimensions), ensure
that no supporting timbers will
be cut.
On the inside wall:
1. Measure the height of the hearth and
mark a horizontal line on the wall at the
same height.
2. Using the template shown in Figure 51,
mark the position of the flue above the
hearth. Drill a pilot hole in the centre
through to the outside wall.
3. From inside the building cut a hole in the
inside wall to accept the flue duct.
Consideration should be given to the
clearances required around the flue duct
in relation to combustible materials within
the installation. Combustible materials
shall be removed and suitably protected
with rockwool or equivalent material as
specified in Figure 41 and Figure 42.
4. A separate hole shall be made through
the inside wall towards the bottom right
hand corner of the fire box location to
accept the electric cable for connecting
the fire box to the fan box assembly.
5. Ensure that any cavity wall insulation or
other combustible materials within the
installation are removed and replaced
with rockwool or equivalent material to
the dimensions and depths as detailed in
Figure 41 and Figure 42.
6. The false chimney breast / fire surround,
if made of combustible materials shall be
suitably protected with 24mm thick
'Superlux' or equivalent material and the
correct thickness of rockwool or
equivalent material as detailed in Figure
41 and Figure 42.
7. Any combustible material to the rear of
the firebox shall be suitably protected
with 24mm thick non-combustible
material and a minimum of 100mm
rockwool. The non-combustible material
can consist of the 13 mm plasterboard
wall lining plus 12mm thick 'Superlux' or
equivalent material.
8. If surface mounting the fan box
assembly, cut an opening in the outer
wall as detailed in Figure 51. Ensure
that the vapour barrier is cut carefully
and made good to maintain its integrity.
9. If recessing the fan box assembly, cut
an opening in the outer wall as detailed
in Figure 50. Ensure that the vapour
barrier is cut carefully and made good to
maintain its integrity.
10. A suitable flashing should be positioned
above the flue duct, extending 150mm
either side, in accordance with the
Institute of Gas Engineers Publication
IGE/UP/7.
11. To prevent water tracking across to the
inner wall surface, a drip collar should be
fitted around the flue duct e.g. a bead of
high temperature silicon.
12.
Temporarily, position the firebox
complete with flue duct attached
centrally into the fire opening. Engage
the flue though the inner wall and to the
outside.
13. Ensure the firebox is flat against the fire
surround.
14. From outside, mark the flue duct flush
with the outer face of the wall.
18. If using flue duct extension, adjust to the
appropriate length, and secure as
detailed in Figure 53.
19. If surface mounting the fan box
assembly, trim the flue duct to the
previously marked position.
20. If recessing the fan box assembly, trim
the flue duct 91mm shorter than the
previously marked position.
21. Proceed to Section 3.7.12
