. 236441BAX) is suitable for
walls between 100mm (4in) and 285mm (11
3
/
16
in)
in thickness.
2. TO INSTALL THE KIT - Mark the flue hole
centre as described in section 5.4 or 5.8. Cut a
hole in the masonry approximately 117mm (4
5
/
8
in) diameter for the internal fitting kit. The use of
a core drill is recommended. (When using a core
drill, it is important to keep the drill level and
square).
3. Measure the wall thickness and from this
dimension subtract 10mm (
3
/
8
in) (Fig. 69).
4. Remove the wall liner from its packing and
remove the end piece (Fig. 70).
5. Mark off the dimension, wall thickness - 10mm
(
3
/

duct and cut off the remaining length of the duct.
Ensure that the cut is square and reasonably
