Take control of your chimney draught
with a chimney fan system
2
Many experience problems
Many homes with wood-burning stoves or fireplaces experience problems when
lighting the fire. Some of the most typical problems are:
Difficulty lighting the fire
Difficulties in lighting the fire can be caused by using poor quality fuel or because the
draught in the chimney is insufficient. The draught in the chimney is caused by the
warm air being lighter than the cooler air outside. As the chimney is cold when lighting the fire the draught is reduced and it can be hard to get the fire started. It is important that the kindling is dry and that you start with small pieces of wood. This will
ensure that the fire will take hold quickly, creating the heat that is necessary to create a
good chimney draught, but sometimes even this is not enough.
Smoke in the room
Spillage can occur if there is insufficient draught. This can be caused by insufficient air
supply or the use of extractor fans. Fireplace and stove size, chimney height and chimney location in relation to nearby buildings can also effect draught and result in smoke
spilling in to the room. It is also important to be aware that the chimney draught can
vary with the season, the outside temperature and the weather (wind, rain, etc).
The fire goes out
Good combustion needs air. The chimney’s “job” is not only to remove smoke but to
draw in fresh air through the supply vents to replace the air used by the fire. If the air
supply is reduced too quickly, uncombusted gasses and particles will exit through the
chimney, causing soot and smokey odours.
Odours and soot
Poor combustion can cause soot build up on the stove door as well as smoke odours.
Damp or wet fuel, an incorrectly set air damper or insufficient chimney draught will
also cause this. Good combustion requires high temperatures and sufficient air supply. If the air supply is reduced too quickly, uncombusted gasses and particles will exit
through the chimney, causing soot and smokey odours.
You are not the one
doing something wrong
3
People are often disappointed when their dream of a cosy warm fire is ruined by insufficient chimney draught.
Many often think it must be something that they are doing wrong when they light the
fire. The simple act of lighting a fire is made difficult by smoky down draughts, soot
or the fire going out. Problems lighting the fire can arise because of incorrect or poor
quality fuel, but in most cases problems are caused by insufficient chimney draught.
Thirty years ago we accepted kitchen smells because we did not have kitchen
extractor fans. Why should we now accept soot and smoke escaping into our rooms,
when a chimney fan will solve the problems caused by insufficient chimney draught.
Many people believe that it is their
fault when the fireplace or stove
causes smoke in the living room.
But the problem is typically caused
by insufficient chimney draught.

Control your chimney draft
with a chimney fan system
Solves your chimney draught problems
and gives you additional advantages
If you install a variable speed chimney fan system you will always have control of the chimney
draught. Apart from providing you with the optimal chimney draught as soon as you light your fire,
a chimney fan system will also give you many other advantages.
Lighting the fire is quick and easy
It will be easier for you to light your fire, regardless of the weather or the
size of your fireplace or stove in relation to your chimney. For the environmentally aware, it is also nice to know that because the fire takes hold
much quicker, fewer particles escape into the atmosphere.
No smoke or odours
Because the chimney fan ensures that the smoke exits through the chimney rather than into your living room, you will not have smoke spillage
and odours, even when you light or refuel the fire.
Improved combustion saves money
The correct chimney draught ensures steady combustion and thus saves
you money. Optimal combustion reduces the amount of fuel needed by
up to 15 %.
Healthier soot-and-smoke-free indoor environment
If you turn the chimney fan on while you clean your fireplace, the fine
ash is extracted up through the chimney instead of escaping into the
room and onto your furniture. Please make sure that the fan is cleaned
afterwards. Your home’s indoor environment is much healthier as all the
particles are sucked up through the chimney.
Additional ventilation
As an extra bonus, when the fireplace is not in use you can use the
chimney fan for ventilation during the summer or winter. If for example
you leave your chimney fan running at low speed overnight after you
have entertained guests, it ensures you will be breathing fresh air, free of
odours the next morning.

A better indoor environment
as an additional bonus
A chimney fan does not just deliver the perfect chimney draught. It can also
improve your indoor climate. When you air the room, vacuum, or use your
cooker hood you do it to improve your indoor climate. A mechanically generated chimney draught can also benefit your indoor environment.
The chimney fan stops soot from covering furniture and fixings. It also ventilates the
room if you turn it on when you are not using the fireplace. It stops ash escaping into
the room if it is turned on while your wood-burning stove or fireplace is being cleaned.
In short, a chimney fan helps you achieve a better indoor environment.

Frequently asked questions
How does a chimney fan work?
The chimney fan is mounted onto the top of your chimney. When the chimney fan is turned
on, it creates a negative pressure in the chimney, causing smoke to be extracted up the
chimney and fresh air to be drawn to the fire, which in turn ensures effective combustion.
Can a chimney sweep clean the chimney when a fan is mounted on the top?
The chimney sweep can easily open the chimney fan and access the chimney which can be
cleaned in the normal fashion.
How is a chimney fan maintained?
Cleaning is the only the maintenance that a chimney fan requires. How often it needs to be
cleaned depends on the kind of fuel being burned in the fireplace or stove. If only dry wood
is used in the fireplace the chimney fan only needs to be cleaned once a year depending
upon usage. Dirt and soot can be removed from the fan using a steel brush or scraper.
Can the chimney fan fall down the chimney?
The chimney fan is fitted to the chimney top using mounting brackets or a flange plate. The
brackets or the flange along with the weight of the fan will keep it fixed in place even in
extreme weather conditions. An additional safety wire means the chimney fan cannot fall
down from the chimney when it is being serviced or when the chimney is being swept.
What happens if there is a power failure?
If there is a power failure, or if the electricity has been switched off, the chimney will function as it did before the chimney fan was installed. The fan will offer very little resistance to
the natural flow.
What is the working lifetime of a chimney fan?
Chimney fans are made of cast aluminium and high temperature resistant materials. This
ensures a long and reliable working lifetime. Many of our fans have been running for more
than 25 years.

A good idea
– and inexpensive to use
Some people believe a chimney fan is expensive to run.
In fact a chimney fan uses no more electricity than a 60 W bulb.

The chimney fan system
An exodraft chimney fan system consists of a chimney fan connected to a manual or semi-automatic control so the chimney
draught can be adjusted according to requirements. The
chimney fan is easy to mount on the top of the chimney
and can tolerate constant temperatures as high as 250 ºC.
The impeller is dynamically balanced to keep vibrations to a
minimum so the chimney fan operates very quietly.
Chimney fans
Chimney fans are available in two model types for solid fuel applications. The RSV model has vertical discharge while the
RS model has horizontal discharge.
Model RSV
Model RS
If the chimney top is above the ridge height of the roof, both RS and RSV type models
can be used. RSV models are recommended for use in windy areas. If the chimney top is
lower than the height of the roof ridge or if the building has a thatched roof we would
also recommend the RSV chimney fan due to the vertical discharge.
Both models are available in various sizes to suit any size of fireplace or wood-burning
stove. RS models have square baseplates as standard but are also available with octagonal baseplates.
The chimney fans can be opened easily,
enabling a chimney sweep
to sweep the chimney and clean the
chimney fan without any problems.

Controls and accessories
Manual control
The EFC16 control unit lets the user manually control the chimney draught.
It has an on/off button and an LED to indicate when the chimney fan is running.
The EFC16 and EFC18 control units must have a repair/isolation switch
fitted to the chimney, this can only be done by a qualified electrician.
Manual/automatic control
The EFC18 control unit is used to regulate the chimney draught. The chimney
fan can either be started manually or automatically. The fan speed is regulated
manually.
The control unit comes with a temperature sensor, which enables the
control unit to stop the chimney fan depending on the temperature in the
chimney. When you restoke the fire you can boost the speed of the chimney fan
to maximum for three minutes with the touch of a button. The chimney fan will
automatically adjust itself back down to the preset speed afterwards. We recommend that the EFC18 is used on closed appliances.
Wireless control
The EW 41 wireless control regulates the chimney draught. It is quick
and easy to install as there is no need for cables between the power unit and
the control panel. The control comes with a temperature sensor that gives you
access to a range of functions and options that not only help improve the indoor
environment but also increase safety, such as:
yy
yy
yy
yy
a boost function, making lighting the fire easier
an alarm function, for example in the case of a chimney fire
an automatic stop function, controlled by the temperature in the chimney
a function indicating when the fire needs relighting/stoking
The wireless control only communicates with electronically paired components
and will not be disturbed by other wireless units such as doorbells, baby alarms
etc.
Flanges
The chimney fan is fitted to a steel chimney using a corrosion resistant flange,
ensuring the chimney fan is mounted onto a level surface. Two types of flanges
are available:
yy FR square flange for RSV and RS chimney fans with square baseplates
yy FR-02 octagonal flange for RS chimney fans with octagonal baseplates

Components for fireplaces or wood-burning stoves
With exodraft chimney fan systems you always have control over the chimney draught regardless of the
weather conditions or other factors influencing the natural draught.
It is the function of the chimney both to remove the smoke
and supply oxygen for effective combustion. In an ideal
situation this is done though the natural chimney draught,
but in reality both the chimney itself and other external
factors affect the natural draught and thus the effectiveness
of the chimney.
1

An exodraft chimney fan gives you complete control over
the chimney draught. The chimney fan is installed on top of
the chimney and creates a negative pressure in the flue, thus
ensuring that the flue gases are extracted up the chimney
rather than into the room. The fan control enables you to
adjust the chimney draught to suit your needs, so you can
enjoy the full comfort of a warm fireplace or wood-burning
stove.
An exodraft chimney fan system for a fireplace or woodburning stove consists of an RS or RSV chimney fan with an
axial vane, a fan control and accessories.
2
The EFC16, EFC18, EFC35 and EW41 controls allow the user
to manually adjust the chimney draught. The EFC18 control
comes with a temperature sensor enabling automatic stop
of the chimney fan after the fire is out. The EFC18 also has
a boost function for extra chimney draught on start-up
or when re-stoking the fire, so smoke down draughts and
odours do not escape into the room.
The EW41 wireless controller is easy to install as no power
supply cables are needed for the control panel.
In addition to having similar functionality as the EFC18, the
EW41 also signals when it is time to re-stoke the fire and
audibly indicates if the temperature inside the chimney
becomes too high. It is easy to see and change the settings
via the display on the control panel.

Components for a solid fuel or biomass-burning boiler
5
A natural draught chimney system is designed to work at average conditions
for the region. So, when a solid fuel or biomass boiler is used all year round,
the variable climatic conditions will sometimes lead to insufficient chimney
draught. The use of a chimney fan system will ensure the correct chimney
draught under any climatic conditions at all times.
1
4
3
When a biomass burning appliance, for example a pellet
stove, has chimney draught problems, this can mean that
lighting the fire can be difficult and may cause soot and
smoke to be expelled back into the room. Insufficient
chimney draught can also lead to poor combustion, and
inefficient use of the fuel.
2
These problems can be solved by installing an exodraft
chimney fan system, because the system ensures the correct
chimney draught is available at all times.

Reset
An exodraft system for a solid fuel or biomass burning
boiler consists of an RS or RSV chimney fan with axial blades,
a controller and accessories. The EFC16, EFC18 or EFC35
controllers allow the user to manually adjust the chimney
draught as needed. The EFC18 controller is supplied with
a temperature sensor and will stop the chimney fan 45
minutes after the fire has gone out. It also starts the fan
automatically if the preset temperature in the chimney has
been reached by lighting the fire and the fan system has not
been started manually. However, it is not recommended to
light a fire unless the chimney fan is already in operation.
The EBC20 control regulates the fan speed automatically,
maintaining constant pressure in the chimney and creating
the optimal conditions to ensure correct combustion.

RS chimney fan
Design and construction
exodraft chimney fans are specially made to
continuously withstand flue gas temperatures of up to
250 °C and continue functioning in dirty environments.
They are constructed of corrosion resistant cast
aluminium and the screws and bolts are made of
stainless steel.
Description
An exodraft RS chimney fan is a specially designed
extractor fan with horizontal discharge.
The fans can be used with all types of fuel burning
appliances and are especially well-suited to appliances
burning solid fuel, such as biomass or solid-fuel boilers,
fireplaces and wood-burning stoves.
The fan is installed on top of a chimney and creates a
negative pressure (suction) along the full length of the
flue and chimney.
The fan is part of an exodraft system and must be
connected to an exodraft controller.
RS chimney fans are available in a range of sizes and
capacities. The RS9, RS12, RS14 and RS16 models are
equipped with stainless steel axial vanes for easy
cleaning.
The RS chimney fan has a temperature resistant, entirely
closed asynchronous motor, with ball bearings sealed
for life. The motor is positioned away from harmful flue
gases and is continuously cooled by a special cooling
plate and cooling vents. The heat-resistant supply cable
has cable-strain relief and is armoured. This all ensures
that the chimney fan has a long and reliable working
lifetime.
The chimney fan can be opened easily, so that a
chimney sweep can sweep the chimney and clean
the chimney fan without any problems. A safety mesh
covers the radial discharge for protection.

EFC16 and EFC35 manual controls
EFC16
EFC35
Description
EFC16 and EFC35 are electronic speed regulators used
to manually control exodraft chimney fans.
The EFC16 or EFC35 speed regulators adjust the
chimney fan's speed, thereby making it possible to
control the chimney fan's capacity (draught) in the
range 25–100 %.
Function
The EFC16 and EFC35 speed regulators are designed for
manual control. When the knob on these controllers is
turned to the right, it will click and the fan will turn on at
full rpm. As the knob is rotated clockwise, the fan speed
will be reduced. To turn the fan off, the knob must be
turned all the way anti-clockwise, until it has passed the
on/off point again.
The speed regulators have a built-in ON/OFF switch in
the control knob, a built-in minimum-speed trimmer,
and an LED to indicate operation. They are CE-certified.
EFC16 or EFC35 control units must have a REP-AFB
isolation switch mounted on the chimney. The isolation
switch must be installed by an authorised electrician.

Temperature sensor
Description
The EFC18 is a manual nine-step speed regulator
with an integrated automatic START/STOP for the
exodraft chimney fan. It also features a boost
function, to make lighting the fire easier. The EFC18
controller comes with a temperature sensor to be
fitted under the fan.
Function
The EFC18 controller switches the chimney fan on
with a simple press of a button on the control panel.
To ensure sufficient up-draught when lighting
the fire, the fan will run at full speed for seven minutes
unless turned down manually. After
the start up period the fan will modulate down
to the speed it was running the last time it was in
operation.
When re-stoking the fire, press the operating button
once. The EFC18 control will then run the fan in boost
mode for three minutes so no smoke or dust will escape
into the room.
The EFC18 temperature sensor, which is
installed under the chimney fan, registers falling
temperature. As the fire dies out and the flue
temperature drops, the controller will (at a preset
temperature of 20, 40 or 80°C) run the fan for 45
minutes before stopping it. This ensures that all the
material in the fire has combusted and also that the fan
is automatically started if a chimney temperature above
a set level is registered.
The fan speed can always be adjusted manually
during operation, but the temperature sensor will
prevent the fan from being turned off while the fire
is still burning and thereby avoid damaging the fan
motor and eliminate the risk of spillage.
A REPSW2x16 isolation switch must be fitted to
the chimney when the EFC18 control system is
installed. The isolation switch must be installed by
an authorised electrician.

EW41 consists of:
yy a control panel
yy a control box with fan repair switch and 5 m cable
that plugs into the mains
yy a temperature sensor to be placed under the fan
(Must be connected to the control box)
The EW41 control panel lets you start and stop the fan
or regulate its speed. The panel saves the last operating
setting and you can read the consumption data in the
display.
The temperature sensor automatically monitors the
system’s temperature to prevent possible overloading
caused by omission. When the fire is lit, the system will
switch on automatically even if you do not activate
the EW41. Once the fireplace is cold, the fan turns off
automatically, so the heat from the dwelling is not sucked
away.
EW41 boosts the chimney draught for seven minutes. So
lighting the fire is quick and easy.
The controller signals when it is time to re-stoke the fire.
Once you have stoked the fire, the panel is activated and
chimney draught is increased for three minutes. This
prevents unpleasant smoky down draughts and your fire
lights faster.
The control panel monitors chimney draught and triggers
the alarm if:

temperature is too high.
The EW41 controller uses radio wave (Z-wave)
communication, which is a very safe system as all
commands are confirmed and there is no risk of
interference from other equipment.

The EBC20 system consists of an EBC20 controller,
which can be positioned anywhere, and a pressure
transducer (XTP sensor) which is positioned in the
chimney.
Function
In installations where several fireplaces or stoves are
connected to the same chimney, the chimney fan
operates continuously. The EBC20 controller monitors
and maintains a specific draught by maintaining
a constant pressure. The pressure in the chimney
is measured by the XTP sensor. If the draught falls
below the set value, the speed of the chimney fan
is regulated until the draught reaches the required
level again.
The EBC20 is usable with all exodraft chimney fan
types.

Isolation switch
It is a legal requirement that an isolation switch is installed in the immediate
vicinity of the chimney fan, so that, for example, chimney sweeps can
disconnect the electrical current to the chimney fan. The type of isolation
switch required depends on the chimney fan control system.

FR flange
FR flanges from exodraft are used to install exodraft chimney fans on steel
chimneys.
The flanges are made of stainless steel and ensure that the chimney fans
have a flat and level installation base. The flange is supplied with four
vibration dampers that reduce vibrations and help create a stable base for
the chimney fan.
The diameter of the flange spigot is 3 mm smaller than the diameter of the
chimney. For example, the diameter of the spigot of an FR1-200 is Ø 197 mm,
designed to fit into a chimney opening with a Ø 200 mm diameter.
FR
The flange range caters for all types of chimney fans and chimneys. Flanges
with diameters other than those shown in the table can be made to order.

Other fitting accessories
Four levelling screws type RSD can be installed between the fan and the chimney to
create dilution air in brick chimneys if the temperature in the chimney is too high.
If dilution air is required, it is important to take the increased capacity need into
consideration when sizing the fan system.
Installing a chimney fan
15
The chimney fan is installed on top of the chimney. The chimney fan
is supplied as standard with adjustable location brackets, armoured
power cable, a safety wire and a mineral wool mat, which ensures
vibration-free operation.
When installing a fan onto a brick chimney the location brackets are
fitted under the chimney fan.
If the chimney fan is to be fitted onto a steel chimney, then a flange
and vibration dampers must be used instead of location brackets
The flange, which includes vibration dampers, must be ordered
separately.
NB! If the chimney has been used previously to a fan being installed,
then it should be cleaned before the chimney fan is switched on,
thus reducing the risks of a chimney fire.
Hiding the chimney fan
Installation of exodraft chimney fans on top of chimneys can
sometimes be difficult due to special site conditions such as listed
buildings or special architectural demands. For those installations it
is possible to make the fans virtually invisible.
Contact exodraft for assistance if such a solution is needed.
Service and maintenance
The chimney fan should be cleaned as often as
needed (at least once a year) depending on the
type of fire fuel.
When the fan is open, it is easy to clean it while
the chimney is being swept.
The chimney fan must always be running when there is a fire in the fireplace, stove or boiler. exodraft
provides a two-year manufacturer's warranty. The exodraft warranty does not include damage caused by fire.
exodraft’s extensive product range is based on more than 50 years of experience and
knowledge in the field of combustion and chimney draft technology.
Our products are known for high safety and quality and we are helping to set the standards
and requirements for draft technology.
exodraft products are all fully documented in accordance with current national and
international standards and are sold in more than 40 countries – for small domestic
fireplaces in private homes to larger commercial and industrial boiler installations.
