Notes.
1. It is recommended that a support bracket is
fitted for every 1 metre of extension pipe used
and a bracket should be used at every joint, to
ensure pipes are held at the correct angle.
If a slip joint coupling is to be used then a
bracket should be used to secure the collar.
2. 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.
3. If the B pack, or telescopic B pack 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.
4. Only use water as a lubricant during assembly.
