HWAM® SMArtControl™
Congratulations on your new wood-burning stove complete with a HWAM®SmartControlTM
We are pleased that you have chosen a HWAM woodburning stove and confident that it will give you
much pleasure.
The HWAM®SmartControlTM is a digital control of the combustion in your new wood-burning stove.The
purpose of the HWAM®SmartControlTM is to control the combustion in an environmentally optimal and
economically efficient way, with a view to generating greater user comfort.
The HWAM®SmartControlTM is a new patented technology, which electronically adjusts the air supply to
the combustion chamber.Your new wood-burning stove continually measures the temperature and the
oxygen levels of the combustion. Moreover, it is programmed to supply oxygen to the fire through three
important air inlets in the right amount, and at the right time and place in the combustion chamber. By
downloading a free app for your smartphone or tablet, you can use the app among other things: to set
the thermostat to the desired room temperature level, choose time for night-time reduction and keep
your stove updated.The app also gives you current information on burning in the stove. See details in
separate manuals for the app IHS Smart ControlTM or in the Quickguide.
.
Your new wood-burning stove and the HWAM®SmartControlTM will ensure the cleanest possible com-
bustion as well as a good fuel economy, regardless of external conditions such as the type of firewood
used, the chimney, the user’s experience, and other external circumstances.
The HWAM®SmartControlTM consists of the following components:
• Air box: the Air box contains a printed circuit board/software, as well as three motors and dampers
that control primary, secondary, and tertiary combustion air.The fresh air system can be mounted
on the Air box to the back or in the bottom.
• Two sensors: a temperature sensor and an oxygen sensor transmit information from the wood-
burning stove to the Air box.
• Room temperature sensor: The room temperature sensor with batteries communicates with the
HWAM®SmartControlTM via a wireless connection. It should be placed so it does not have direct
radiant heat from the stove. Note that the maximum distance between stove and room temperature
indicator is about 4-5 metres.The range is reduced if there are walls or other obstructions between
the stove and the room temperature indicator.
• Electricity supply: from the Air box to the nearest wall socket.
• App "IHS Smart ControlTM:The app can be downloaded free from the App Store or Google Play
Store. See details in separate manuals for the app IHS Smart ControlTM or in the Quickguide.

In general
To ensure optimum operation and safety,we recommend that the installation should be carried out by an
authorised HWAM retailer or a fitter recommended by the retailer.For an overview of HWAM retailers,
visit www.hwam.com under “Retailer locations”.
Safety
The installation of your HWAM woodburning stove must always comply with all European, national and
local building regulations.The installation must be carried out in accordance with the instructions in the
installation and user manuals and subsequently registered with the local authorities. Upon installation,
the chimney sweep must approve the installation before you can start using the woodburning stove.All
HWAM woodburning stove packaging material must be handled in accordance with local waste manage-
ment regulations.
Room requirements
Always ensure a supply of fresh combustion air to the room where the stove is to be installed. The
woodburning stove uses approx. 7-21 m3 of air per hour.A window that can be opened or an adjustable
air valve will be sufficient. It must not be possible to block the adjustable air valve/grate. In newly built/
airtight dwellings, we recommend that a fresh air system should be installed for the direct supply of
external air to the combustion.This fresh-air system may be bought separately.
Before installing the stove, you must ensure that the load-bearing capacity of the floor can withstand the
weight of the stove and the chimney. The weight of the chimney should be calculated according to its
dimensions and height. Remember to consider that the stove must be connected to power.

Remember to pay attention to the applicable regulations concerning the required distance
between the wall and smoke pipe.
The distance to a brick wall is set to faciliate the servicing of the HWAM®SmartControl™.
Please be aware that not all glass parts are heat-resistant. For this reason, a glass wall should sometimes
be treated as a combustible wall, in which case we ask you to contact your local chimney sweep or glass
producer to hear at what distance the stove should be kept from glass.
Requirements for chimney and smoke pipe
The height of the chimney must ensure sufficient draught and prevent any smoke nuisance.As a general
rule, satisfactory draught conditions are achieved if the chimney is 4 m above the stove and at least 80
cm above the ridge. If the chimney is placed at side walls, the top of the chimney should always be higher
than the ridge or the tallest point of the roof.Always be aware of any national and/or local regulations
applying to thatched roofs and the location of the chimneys.
The stove requires a minimum draught of 12 Pa (measured at EN 13240 measurement point).If measured
just above the smoke flue socket, the chimney draught must be 18-20 Pa.
The chimney must have a minimum clearing of Ø 150 mm. The chimney must be provided with an
easily accessible cleaning door.The chimney and flue duct must be of flue class T400 and be CE marked.
Furthermore, it must have obtained the classification of G in soot fire testing.The required distance to
combustible material must be complied with in accordance with the brand label.Ask your HWAM retailer
for further information.
