The Chimney
The chamber should be closed off above the stove with a concrete slab,
lintels or Thermalux board. If there is to be a masonry chimney then it
should be lined with pumice liners (not clay liners) of the correct
diameter and the starter block should be set on the slab.
The stove is then connected to the starter block with an adjustable
length of single skin flue. If it is to be a stainless steel insulated chimney
then the hole in the chamber roof should be a good fit around the pipe
and the void above it ventilated. If it is going into an existing chimney
then that should be lined with a class 1 flexible liner of the correct
diameter, and the liner should be insulated. The stove should connect to
the appliance via a length of rigid flue at least 500mm long. The liner
should be firmly fixed to the chimney wall with a bottom support bracket
or, if that isn't possible, then every pipe connection, including the
connection to the stove, should be secured with stainless steel self-
tapping screws. The chimney should be fitted with a cowl or appropriate
chimney pot to prevent rain entry.
Flue Diameters
To ensure a good draw on the chimney, yet prevent overdrawing, Fondis
fit a large diameter flue spigot on the stove and the correct adaptor is
then used to adapt it to the diameter recommended for each individual
flue height.
