The flue must satisfy all building, fire and heating regulations and be capable of with
standing temperatures up to 980 Deg C.
A straight vertical flue is in all cases the most efficient, if however bends have to be
fitted never use more than two elbows, the angle of which must not be greater than 45
degrees.
Flue Assembly
- The chimney should be installed with the maximum possible amount of vertical
runs. 15
o
& 30
o
bends should be used if possible where flue must change
direction. The distance between the bends should not exceed 20% of the
overall flue length.
- The minimum distance from consumables as stated by the manufacture must
be adhered with fire stops and support plates fitted as required. Where there is
a risk of combustibles making contact with a chimney the minimum distance
must be maintained.
- Ensure termination of the chimney is the adequate height from the roof of the
building and any opening windows or ventilation. This should be 1metre above
the Apex of the building.
- A minimum of 600mm vertical pipe should be installed straight off the appliance
spigot.
- The chimney should be adequately supported as per manufacturer’s
instructions.
- Joints within a floor or ceiling construction are prohibited.
The above points are only a guideline to correct flue installation.
The flue manufacturer’s instructions must be adhered to. Talbott’s can supply these
upon request. Flues are required to meet Part J of the building regulations and confirm
to HETAS (or equivalent) requirements. Refer to relevant industry standards for further
guidance.
NEVER ATTEMPT TO TAKE THE FLUE HORIZONTALLY
Consult your local authority regarding any planning permission that may be required
for the height and position of the flue or regarding any bye-laws for the installation.
You should also check with your regulatory authority any potential permitting or
exemption requirements. This rule applies to any appliance you may choose.
