Installation onto a steel chimney
If the fan is to be fitted on a steel chimney, the chimney fan must be installed with an approved flange.
See the installation guide below.

Illustration
1
The flange must be placed so that the spigot goes
into the chimney!
Measure the diameter of the hole in the flange.
2
Then cut a hole in the mineral wool mat that
matches.
Note that there must always be a minimum of
20 mm of mat surface at any point around the
circumference of the hole.

3
Cut the corners off the mineral wool mat, so there
is room to fit the vibration dampers.
If a temperature sensor is to be installed with the
chimney fan, cut a groove in the mineral wool mat
that is big enough for the sensor.
Now place the mineral wool mat on the flange
(between the flange and the fan).
