Precautions and user instructions
These instructions, applicable standards and relevant safety procedures from the manufacturer must be
followed and at the same time the ofcial provisions in force in the country, where the product is installed,
must be observed.
Support system
Prior to installation of a chimney fan, it must be determined if the chimney can safely carry the weight of the
chimney fan.
A steel chimney should be well supported at the roof penetration point. If the chimney extends high above
the roof, the chimney and the fan should be secured. The manufacturer´s instructions must be followed.
Brick chimneys do not usually need any kind of support to carry the weight of the chimney fan.
System type
Gas replaces and individual gas-red boilers used in private dwellings normally operate in a relatively
stable environment, where no major pressure uctuations occur. However, to secure an optimal use of the
Exodraft system speed adjustments and adjustment of air intakes are required depending on the weather
outside and on the stage of the ring process.
Gas replaces and individual gas-red boilers used in restaurants are exposed to major pressure changes
due to factors like the constant opening/closing of doors, kitchen exhaust fans pulling out air, etc. In an
environment like this spillage of smoke can easily occur.
The fan must be connected to an Exodraft control type EFC21.
Precautions
Be aware that it
• must be installed on top of the chimney
• can be mounted on steel as well as brick chimneys
• must be mounted with the approved Exodraft accessories
• must be accessible for service and maintenance from the roof or from a ladder/cherry picker
• the distance to ammable materials must be at least 500 mm
• the isolation switch must be easily accessible
ATTENTION! It is always recommended to install a
smoke alarm in connection with a wood red installation.

Multiple fans on chimney
If two or more chimney fans are required to create sufcient draft, installation procedures are almost the
same as for single fan installation. See the installation guide below.
Multiple fans on a brick chimney
1
If two or more fans are required to create suf-
cient draft, a special adapter plate is required
(not an Exodraft part). The two holes in the plate
should match the throat diameter of the fan
model used and the distance from center to center
should be at least equal to the fan width. Exodraft
recommends that a partition is mounted between
the fans.
The adapter should be sealed with silicone and
bolted onto the top.
When installing multiple fans, it is extremely
important that the fans are of the same model
and size, and they must be controlled in tandem
by one motor speed control.
A similar approach should be taken if the ue size
exceeds the fan base dimensions. The adapter
plate should be sized so it covers the ue and
secured. A hole should be cut in the center of the
plate and the fan mounted centered over the hole.
Multiple fans on a steel chimney
1
If two or more chimney fans are required to create
sufcient draft, the installation procedures are
basically the same as for single fan installation
on a steel chimney. However, as the fans will be
placed next to each other, a special plenum box
will be required (not an Exodraft part).
Exodraft recommends that a partition is mounted
between the fans.
When installing multiple fans, it is extremely
important that the fans are of the same model
and size, and they must be controlled in tandem
by one motor speed control.

Electrical installation
The fan and motor specications are provided on the fan’s type plate. All the single-phased fan models are
adjustable in speed. Wires are to be connected in accordance the wiring diagram. For further details, please
see guidelines for the Exodraft control units.
Any lightning conductor connected to the fan must respect current applicable national legislation.
DANGER! Check that the heating appliance (water heater, furnace, etc.) is
working properly after the chimney fan has been switched on. Make sure that
no ue gases are spilling out as this can lead to carbon monoxide poisoning!
