Notes.
1. When extension ‘D’ packs are used the flue duct MUST be inclined at 1.5
degrees to the horizontal to allow condensate to drain back into the boiler
and out through the condensate drain.
2. If the telescopic ‘B’ pack or horizontal flue terminal (600 long) only are
used, they may be mounted horizontally. The 1.5 degrees is taken care of
by the inclination of the flue within the air pipe
3. If the boiler is to be installed with downward piping routed behind the boiler
then the optional stand-off kit should be used. Care must be taken when
cutting the ducts and marking the wall to suit this condition.
