27 DETERMINING THE FLUE LENGTH AND FLUE PACKS REQUIRED

For the 100mm concentric flue system
Dimension X - Wall thickness.
Dimension L - Wall thickness plus boiler spacing.
Dimension R - Wall thickness plus boiler spacing.
FLUE KITS
Pack B - supplied as standard
Flue Finishing Kit - supplied as an optional extra
Pack D - optional extension kit for side flue or rear flue
outlet.
Screw Kit - Optional kit for mechanical fixing of flue joints
Refer to 'Flue Extension Ducts'
For RH Side Flues
- If the appliance is installed at minimum clearance from a standard cavity wall the horizontal flue kit (600mm long)
is required.
- If the telescopic flue kit is used, an additional 'D' Pack Extension will be needed.
For LH Side and Rear Flues
- For minimum clearance from standard cavity wall the telescopic flue kit only is required.
Note.
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.

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. Do not
use mineral based oils.
