FLUE OPENING:
Follow the diagram opposite to mark the
centre of the flue (1, & 2) for rear opening,
(2 & 3) for side opening or
(1 & 4) for top opening.
** IMPORTANT: for horizontal flues, increase
this height by 52mm for every 1000mm of
horizontal length that the flue opening is
away from the boiler.
NOTE: all horizontal flue sections must rise away
from the boiler by 52mm per metre to ensure that
condensate flows back into the boiler for safe
discharge via the condensate waste pipe.
Make an opening (F, G or H) through the wall
using a core drill or similar at a size relative to
the wall thickness as shown below:
