12A DETERMINING THE FLUE LENGTH AND FLUE PACKS REQUIRED, CONT'D
Notes.
1. It is recommended that a support bracket is fitted for
every 1 meter 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 telescopic 'B' pack, or horizontal flue terminal (600
long) only are used, they may be mounted horizontally.
The 1.5 degreesis taken care of by the inclination of the
flue within the air pipe.
4. If the boiler is to be installed with upward 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.
5. Only use water as a lubricant during assembly. Do not
use mineral based oils.
