14 DETERMINING THE FLUE LENGTH AND FLUE PACKS REQUIRED
IMPORTANT. The boiler MUST be installed in a vertical position.
Dimension X - Wall thickness.
Dimension L - Wall thickness plus boiler spacing.
Dimension S - Stand-off frame depth = 33mm.
Note. MAXIMUM FLUE LENGTHS:
HORIZONTAL FLUE - 6M
ROOF FLUE KIT - 7.5M
POWERED VERTICAL FLUE KIT - 5m primary and 17m secondary is a typical maximum
90 O ELBOW KIT 60/100 (EQUIVALENT FLUE LENGTH RESISTANCE = 1M)
45 ELBOW KIT 60/100 (EQUIVALENT FLUE LENGTH RESISTANCE = 0.6M)

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.
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.
It is recommended that a support bracket is fitted for every 1 metre of extension pipe used and also at every joint to ensure
pipes are held at the correct angle. If a slip joint coupling is used then a support bracket must be used to secure the collar.
