1.3 Sources of danger
1.3.1 Fire protection
The entire system must comply with technical fire protection requirements in accordance with the applicable
regulations, standards and guidelines.
All flammable materials in the close vicinity of the pellet central heating boiler for living areas must be protected
against the effects of heat, in particular in the area of the front window.
Attention!
Do not drape clothing or other items over the FireWIN for drying them.
Do not touch the front window – danger of burns.
1.2 Safety precautions
The boiler and related accessories are state of the art and meet all applicable safety regulations and operate
using 230 V AC electrical current. Improper installation or repair can pose the danger of life-threatening electrical
shock. Installation may be performed only by appropriately qualified technicians.
Caution symbols
Please take careful note of the following symbols in this Operating Manual.
Attention!
Ignoring the warnings identified can lead to personal injury.
Information!
Ignoring the warnings identified can lead to malfunction of, or damage to the boiler or heating system.
Note!
The blocks of text highlighted provide information and tips for operation.
1.3.2 Power failure (or if the blower is not running)
Attention!
Do not open the combustion chamber door, there is an increased risk of deflagration when opening
the combustion chamber door. A self-test is performed following a power failure during combustion
and then operation is continued automatically.
1.3.3 Burner pot
Attention!
Never fill the burner pot with pellets by hand. Excessive combustion material in the burner pot means
that the pellets will not be ignited optimally. Too much low temperature carburisation gas will be gene-
rated and this can lead to deflagration.

1.3.4 Entering the pellet storage room, storage container
All energy sources are subject to safety regulations which must be observed when working with fuels, heating
systems and storage rooms. This also applies to the storage of pellets.
After the storage room is filled, odourless carbon monoxide (CO) may be produced and there may be insuffici-
entoxygen. For this reason, do not enter the pellet storage room for 6 weeks after it has been filled. Only trained
persons may enter the storage room for the purpose of measuring gas levels.
Please also follow the instructions on the sticker:
– No access to unauthorised persons, keep children away from the pellet store!
– Ensure sufficient ventilation before entering. Keep the door open while inside.
– Only enter the storage room under the supervision of a second person standing outside.
– No smoking, flames or other sources of ignition are permitted.
– Risk of injury from moving parts.
– Pellet boilers must be switched off at least 15 minutes before filling.
– Fill in accordance with the instructions of the boiler and pellet suppliers.
– Protect pellets from damp.
If you feel unwell, leave the storage room immediately and seek medical advice.
Attention!
Do not attempt to enter an unaired storage room (particularly buried tanks).
1.4 Fuel
To ensure that your new heating system provides long-term reliable service, the following must be observed:
Quality of pellets must be in accordance with EN 14961-2 A1:
The quality of the pellets is an important factor in achieving optimum operation of the heating system. When
buying pellets, make sure that they meet the quality standards of EN 14961-2 A1 (or ÖNORM M7135 / DINplus).
For maximum reliability, source pellets from manufacturers with EN-Plus certification (or DIN-Plus, ÖNORM
M7135 or UZ38), as they are required to perform ongoing internal quality control.
Make your pellet supplier aware of these quality requirements before ordering and seek confirmation upon de-
livery.
Consequences of quality fluctuations:
Pellets are 100% unprocessed wood, so minor fluctuations in fuel quality are normal and reflect the natural ori-
gins of the material. These quality fluctuations affect the level of dirt, the ash content and therefore the cleaning
intervals.
A reduction in cleaning intervals due to fluctuations in pellet quality cannot be remedied as part of a repair under
guarantee!

required by the guarantee limitations and undertaken by Windhager Customer Service or a customer service
partner will guarantee the optimal use and service life of your boiler system. This is the only way to assure the
benefits of this technologically advanced boiler and guarantee safe, environmentally friendly and energy-saving
system operation.
The following preconditions must be met before you order the initial start-up:
1.) Boiler installed correctly.
2.) System fully wired up electrically.
3.) System rinsed, filled and vented – heat consumption must be possible.
4.) Boiler connected to domestic water and filled.
5.) Sufficient quantity of fuel available (pellets, split logs, oil or gas).
6.) The customer must be present during start-up.
The initial start-up cannot be carried out if any of these points are neglected. The customer will be charged for
any unnecessary costs arising as a result.
Start-up and maintenance by Windhager Customer Service or a customer service partner are part of the gua-
rantee requirements of the enclosed “guarantee limitations”.
Note!
During the first few weeks after start-up, condensation can occur in the combustion chamber, ash pan
and on the heating surfaces. This has no effect on the function and service life of the boiler.
1.6 Functional test
EN 12828 and ÖNORM B8131 require that the function of the system and related safety equipment be checked
and certified yearly by a qualified technician (installer, heating system contractor).
At two-year intervals, the heating water condition must be checked (ÖNORM H 5195-1 Expenditure 2010) by a
heating expert (installer) (see FireWIN installation instructions – Heating water); this is to prevent corrosion and
sediment accumulation in the heating system and boiler.
In the event of repair work requiring a change of water in the heating system, the heating water is to be checked
within 4 to 6 weeks after such work.
Corrosion and sediment resulting from improper heating water are not covered by the guarantee and warranty.

Fig. 3 „Storage room fill“ sticker on the
storage room door
Pressing one of the six buttons firstly switches just the lighting and display on. The boiler is only switched off
when the button is pressed for the 2nd time. Wait until burnout mode has finished (not indicated on the display)
and open the combustion chamber doors.
During filling, negative pressure is created in the pellet store and this can cause burn-back in the pellet boiler.
Therefore, the boiler must be stopped from operating during the filling procedure.
Every storage room fill should be documented by adding the date and volume to the „Storage room fill“ sticker –
Fig. 3.
Attention!
The pellet boiler must be switched off correctly at least 15 minutes before the store is filled –
Fig.2. Press the ON/OFF button. Never switch off using the emergency OFF switch!
1.7 Filling the pellet store
1.8 Operating noises
The FireWIN is a modern, fully automated pellet central heating boiler for living areas with a high level of con-
venience in terms of operation and cleaning. This automation means that operating noises may occur during
normal operation.
Normal operating noises are:
Flame noises – Natural flame noise can be heard depending on the size of the flames.
Light scratching and scraping noises – Depending on the level of contamination, cleaning noises may occur
during automated cleaning or shake-out. If these become louder over time èClean the pellet central heating
boiler, especially the burner pot.
Trickling of pellets and vacuum cleaner noise – Fully automated pellet supply involves pellets being sucked
from the storage room into the reserve supply container. During filling, the suction turbine generates a „vacuum
cleaner noise“ in the storage room and the feed hose, and the trickling of the pellets can be heard in the reserve
supply container.
Clicking noises – The relays switch on or off when the control unit is installed.
Liquid noise, gurgling – This is caused by air in the heating water èBleed the system.
Air induction noises – Air induction noise occurs at the air supply induction point for combustion (air opening in
the device) èFor information on routing the induction point through air supply pipes and into an adjacent room
or about a form of operation that is independent of the room air, see the FireWIN assembly instructions.
Auger conveyor noise – During operation, the drive motor for the auger conveyor may emit low-level intermittent noises.
Note!
Due to these operating and flame noises, we do not recommend installing the device in bedrooms or
quiet rooms – see also the information in the FireWIN „Assembly instructions“.

2. Operation
2.1 Functional description, function elements and operating
controls
The FireWIN pellet central heating boiler for living areas and the Modular Energy System MES or the REG stan-
dard control combine to form a perfect unit. The FireWIN automatically fires when the control system signals a
heating requirement. Following „purging“ (safety function), ignition starts and the pellet metering auger switches
on. The burner pot is automatically filled with pellets. When flame formation has been detected (by the thermo-
control sensor), the boiler enters flame stabilisation mode and then control mode (modulation mode) and keeps to
the specified boiler temperature setpoint (between 60 °C and 75 °C). The boiler enters burnout mode if the output
drops below the minimum nominal thermal output or no heating requirement is signalled by the control system.
The blower continues to run until the burner pot has cooled down. Therefore, do not switch off the electricity sup-
ply to the device too soon.
2.1.1 FireWIN Klassik
The reserve supply container is loaded by hand. The heating surfaces are cleaned manually using the cleaning
lever. The cleaning residues from the heating surfaces and the combustion residues from the burner pot drop into
the ash pan or ash pan space.

2. Operation
2.1.2 FireWIN Premium
Version as FireWIN Klassik, but in addition with fully automated pellet feed
The pellet feed uses a maintenance-free suction turbine to fill the FireWIN reserve supply container fully automa-
tically with pellets from a pellet storage room or storage container. The pellet feed is switched on by the lower fill
level switch (proximity switch) in the reserve supply container or at the end of the enable time or the beginning of
the start time, and runs for as long as the reserve supply container is full. Filling is not started if the boiler is in
heating operation or the feed has been blocked by the control unit (outside the enable time, e.g. at night). If the
boiler is operating when filling is necessary, the boiler switches to burnout mode.
Switching between suction probes 1, 2 and 3 is a fully automatic process. The system changes to the next suction
probe after the reserve supply container has been filled a certain number of times. This means the storage room
is emptied as evenly as possible.

b) Ventilation:
Please make sure the boiler room is well ventilated. The air supply must be as free of dust as possible.
c) Flue:
Please have the chimney sweep check the flue, and, if necessary, clean it.
2.2 Check before initial start-up
a) System pressure (heating water pressure):
The system must be filled and vented. With the system cold, pressure should be at least 1.0 bar (maximum 1.8
bar) – Fig. 9 If you have any questions, your installer will gladly answer them.
Fig. 9 Filling the system
Pressure gauge (system pressure)

2.1.4 Heat shield (accessory FIRE 023)
Heat radiated from the front window can lead to unwanted heating of the room where the unit has been set up
when domestic hot water is being heated during the summer. If you do not want the room to be heated, you can
significantly reduce the amount of heat radiated using the patented heat shield (accessory Fire 023).
The air-to-water ratio without a heat shield is approx. 15 : 85 % and with a raised heat shield approx. 9 : 91 %.
The heat shield is located in the combustion chamber. This can be pulled up using the supplied Allen key and
hooked into the lugs on the sides of the combustion chamber cover plates, Figs. 7, 8.

2. Operation
Information!
Do not open the reserve supply container cover unless the glass cover is closed, in order to avoid
damaging the glass cover.
When filling, make sure no extraneous materials (e.g. shreds of the pellet bags resulting from cutting
open the bags) enter the reserve supply container – they could block the rotary feeder!
Tip!
The reserve supply container should always be completely filled with pellets. This allows the inco-
ming pellets to drop into the container better, reduces the size of the conical part of the pile and
means that the container empties better.
Fold open the cover of the reserve supply container (Fig. 10) and fill the reserve supply container up to max. 1 cm
below the edge. Close the cover.
Fig. 10 Folding open the cover
2.3 Filling the reserve supply container
2.3.1 FireWIN Klassik – Manual filling
2.3.2 FireWIN Premium and Exklusiv – fully automatic filling
The reserve supply container is filled by the fully automatic pellet feed. Windhager Customer Service or the cus-
tomer service Partner will perform the first fill (start-up), take the boiler and its pellet supply into service and
familiarise the customer with the operation and cleaning of the boiler, with reference to the Operating Manual.

2. Operation
2.5.4 Solid fuel/buffer mode
If the FireWIN pellet central heating boiler for living areas is combined with a
solid fuel boiler or an buffer tank, the WVF or B-PLM automatically switches
over between pellet and solid fuel/buffer mode.
Combustion of the FireWIN is stopped when the WVF or B-PLM module sends
the request to switch over to solid fuel/buffer mode – Fig. 20.
Following this, the system switches over to solid fuel/buffer mode and the
FireWIN burner is locked – Fig. 21
If the pellet central heating boiler for living areas is switched off using the ON/
OFF button on the InfoWINplus, an automatic switchover to solid fuel/buffer
mode is performed in conjunction with a WVF module. Once the InfoWINplus
unit is switched on, the pellet central heating boiler may be locked for a maxi-
mum of 15 minutes due to the switch-over delay. This is displayed by InfoWIN-
plus – Fig. 21.
After an hour in solid fuel/buffer mode, the display is shut down fully, only the
green LED is lit up. The display is switched back on by pressing a button or when
there is a heating requirement.

2.5.5 Manual operation
Note!
Manual operation cannot be started in “solid fuel/buffer
mode”. Manual operation must not be started if an installed
solid fuel boiler is operating (heated up). Manual operation
may be started if there is no solid fuel boiler installed or if this
is not operating but only the accumulator tank is active. In this
case, first set the operating mode switch on the WVF to relay
test 2 or on the B-PLM to relay test 1 (see WVF or B-PLM ope-
rating manual).
Pressing one of the six buttons switches the lighting and
display on. Manual operation starts if the Manual operati-
on / chimney sweeper function button is pressed for more
than five seconds – Fig. 22. This sets the boiler tempera-
ture to the setpoint fixed for manual operation (standard
value 60 °C). The current automatic setting is not affected
by this. The lighting is switched off after the lighting timer
has counted down (10 min.); the function or display remains
unchanged.
Pressing the Cancel button or Manual operation / chimney
sweeper function button terminates the function – Fig. 23.
The boiler returns to automatic operation.
Setpoint adjustment for manual operation
By pressing the +or –button the display switches to the
setpoint adjustment mode – Fig. 24. Using the +or –button
can change the setpoint in 1 K steps. The temperature set
in this mode is not permanently saved. The original set tem-
perature is used once manual operation ends.
After pushing the Back button (Fig. 25) or after waiting 45
seconds, the screen returns to its previous display.

2.5.6 Chimney sweeper function
This function aids the performance of legally-required
emissions testing.
Note!
The chimney sweeper function cannot be started in “solid
fuel/buffer mode”. The chimney sweeper function must
not be started if an installed solid fuel boiler is operating
(heated up). The chimney sweeper function may be started
if there is no solid fuel boiler installed or if this is not ope-
rating but only the accumulator tank is active. In this case,
first set the operating mode switch on the WVF to relay test
2 or on the B-PLM to relay test 1 (see WVF or B-PLM ope-
rating manual).
A short press of the Manual operation / chimney sweeper
function button switches on the lighting and display. Pres-
sing the button again starts the chimney sweeper function
– Fig. 26. The boiler temperature is set to approx. 60 °C for
45 min.
Pressing the corresponding menu button enables the boi-
ler to be operated with 30 % or 100 % output – Fig. 27. The
lighting is switched off after the lighting timer has counted
down (10 min.); the function or display remains unchanged.
Only the lighting is switched on when the button is first
pressed.
The operating time is reset to 45 min. when the Manual ope-
ration / chimney sweeper function button is pressed again.
The chimney sweeper function ends
– when the Cancel button is pressed – Fig. 28.
