APPLICATION

suitable for relining within a masonry chimney. Flue liner is suitable for use
with burning gas, oil, coal, coke, cured dry logs, cured dry peat, smokeless
fuels.
If the appliance is mainly going to be used to burn
wood, and the appliance is not DEFRA approved you should increase the diameter
of the Flue Liner to 150mm (providing this will fit in the masonry chimney), as
recommended by Building Regulations.
CONSTRUCTION
The flue liner has a smooth inner liner
made from 904L grade stainless steel and is 0.12mm thick. The flue liner has a
convoluted outer skin made from 904L stainless steel and is 0.12mm thick. The
Flue Liner is constructed from a single strip of steel which is bent at 180
degrees and then the seam is folded in four planes to give a quattrolock
seal.

Secure a piece
of string (at least the same length as the Flue Liner to the Nose Cone (order

Now attach the Nose Cone onto the end of the Flue Liner, again
making sure the arrows on the Flue Liner are pointing away from the Nose Cone in
a upward direction so when the liner is installed the arrows will be pointing to
the top of the chimney

at the same time have someone at the top of the chimney feeding the Flue Liner
down, once the Flue Liner is fitted remove the Nose Cone.
