Side Flue Application
Having selected the boiler location,
with due regard to boiler clearances
and the terminal position.
Position the wallplate/template on the
wall. Mark the top and bottom boiler
mounting hole positions.
Remove the wallplate/template, drill
the holes and then secure the wallplate/
template with the fittings provided.
Mark and extend the flue horizontal
centre line to the corner of the
adjacent surface.
Mark out and cut the hole for the flue
using, preferably, a 115mm minimum
core drill.
If the wall thickness “Q” is less than
300mm cut the wall sleeve to the
required length.
Fit the wall sleeve.
Make good around the wall sleeve at
both the internal and external wall
faces (through the wall sleeve if
internal access only is available).
If the wall thickness “Q” is greater than
300mm the wall sleeve must be fitted
flush with the internal wall face.
Make good at the internal wall face,
leave the external wall face until later.
If the inner end of the sleeve sticks out
into the cavity then, if desired, the wall
sleeve can be trimmed back to the depth
of the inner skin of the brickwork.
