Important information for system operators

1.3 Start-up and maintenance

Please permit Windhager Customer Service or have one of our customer service PARTNERS put your new boil­er into service. In this way, all functions of the new unit will be thoroughly checked; you will also benefit from
the detailed information provided by the system installer. Installation by a qualified technician as well as the
maintenance required by the guarantee limitations will guarantee the optimal use and service life of your boil­er system. This is the only means 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 is neglected. The customer will be charged for
any unnecessary costs arising as a result.

Start-up and maintenance are part of the guarantee 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.

1.4 Heating water

The chemical composition of the heating water must meet the specifications of ÖNORM H 5195 Part 1 or VDI
2035 P1. According to ÖNORM M 5195 Part 1, the condition of the heating water must be checked every 2 years
by a heating technician in order to avoid corrosion and sediment accumulation in the heating system.

The check must be performed once every year in heating systems with more than 1500 litres of heating water.
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.

1.5 Operating noises

The FireWIN is a modern, fully automated pellet flue-connected boiler with a high level of convenience 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 ash removal. If these become louder over time ⇒ clean the pellet flue-connect­ed boiler and, in particular, 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.

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 gen­erated and this can lead to deflagration.

During filling, negative pressure is created in the pellet
store and this can cause burn-back in the pellet flue-con­nected boiler. Therefore, the boiler must be stopped from

operating during the filling procedure or 15 minutes in
advance.

The pellet flue-connected boiler must be switched off at the ON/OFF button on the InfoWIN at least 15
minutes before the store is filled – Fig. 2.

1.6.4 Pellet storage room or storage container filling

1.6.3 Burner pot

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.

1.6 Sources of danger

1.6.1 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 flue-connected boiler must be protected against the
effects of heat, in particular in the area of the front window.

Fig. 2 Switching off FireWIN

Do not drape clothing or other items over the FireWIN for drying them.

1.6.2 Power failure (or if the blower is not running)

Important information for system operators

Do not touch the front window – danger of burns.

Liquid noise, gurgling – This is caused by air in the heating water ⇒ bleed the system.
Air induction noises – Air induction noise occurs at the air supply induction point for combustion (air opening

in the device) ⇒ Use air supply pipes to relocate the induction point outside the house or into an adjacent room.
Light whistling noises – Above the front window on the door frame, there are openings for the window air-

wash function that can give rise to whistling noises if they are dirty ⇒ clean the holes.

Operation

2.1 Functional description, function elements and operating
controls

The FireWIN pellet flue-connected boiler and the Modular Energy System MES or the REG standard 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 (temperature 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 heat
consumed 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 supply 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.

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 auto­matically 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 (not during 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 wands 1, 2 and 3 is fully automatic. The system changes to the next suction wand
after the reserve supply container has been filled a certain number of times. This means the storage room is
evenly emptied to a large extent.

Operation

2.1.3 FireWIN Exklusiv

Version as FireWIN Premium, but in addition with fully automated heating surface cleaning and ash
compactor

Fully automated heating surface cleaning:
A motor moves the heating surface cleaning system vertically and the heating surfaces remain clean.

Fully automated ash compactor:
The fully automated ash compactor uses a motor and pressure plate to compress the ash in the ash container

fully automatically. This makes the emptying intervals up to 3 times longer.

Operation

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. 8. If you have any questions, your installer will gladly answer them.

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 heated during the summer. If you do not wish for the room to be heated, you can
significantly reduce the amount of heat radiated using the patented heat shield (accessory Fire 023).

The distribution of heat between air and water heating is approx. 15 : 85 % without the heat shield and approx. 9 : 91 %
with the heat shield pushed up.

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. 6, 7.

Fig. 6 Hooking in the Allen key Fig. 7 Pulling up the heat shield and hook-

ing it into the lugs on the sides

Pressure gauge (system pressure)

Fig. 8 Filling the system

b) Ventilation:

If you are operating the device with room air, please make sure the room where it is installed 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.

2.3 Filling the reserve supply container

2.3.1 FireWIN Klassik – Manual filling

Note: Do not open the reserve supply container cover unless the glass cover is closed, in order to avoid dam­aging the glass cover.

Fold open the cover of the reserve supply container (Fig. 9) and fill the reserve supply container up to max. 1
cm below the edge. Close the cover.

T

ip: The reserve supply container should always be completely filled with pellets. This allows the incoming pel­lets to drop into the container better, reduces the size of the conical part of the pile and means that the con­tainer empties better.

Fig. 9 Folding open the cover

When filling, make sure no extraneous materials (e.g. shreds of the pellet bags resulting from cutting
open the bags) get into the reserve supply container – they could block the rotary feeder!

2.3.2 FireWIN Premium and Exklusiv – fully automatic filling

The reserve supply container is filled by the fully automated pellet feed. WINDHAGER Customer Service or the
customer service PARTNER will perform the first fill (start-up), take the boiler and its pellet supply into service
and familiarize the customer with the operation and cleaning of the boiler, with reference to the Operating Man­ual.

2.5.4 Solid fuel / buffer mode

If the FireWIN pellet flue-connected boiler is combined with a solid fuel boil­er or an accumulator tank, the WVF or BUL module automatically switches
over between pellet and solid fuel/buffer mode.

Combustion of the FireWIN is stopped when the WVF or BUL module sends
the request to switch over to solid fuel/buffer mode – Fig. 19.

Following this, the system switches over to solid fuel/buffer mode and the
FireWIN burner is locked – Fig. 20

If the pellet flue-connected boiler is switched off using the ON/OFF button on
the InfoWIN, an automatic switchover to solid fuel/buffer mode is performed
in conjunction with a WVF module. Once the InfoWIN unit is switched on, the
pellet flue-connected boiler can be locked out for a maximum of 15 minutes
due to switch-over delays. This is displayed by InfoWIN – Fig. 20.

The factory setting for the “Feed operating modem” menu item is

without time control: Select this if the feed noise (suction turbine)

cannot be heard or is not disruptive in the living area (also in
adjacent premises). This mode guarantees the fewest possible
feeds because the reserve supply container is always “run to
empty”.

Functional description: The pellet feed is automatically switched
on at any time as soon as the reserve supply container is empty.

with start time: Select this if you want the feed to start at the same

time every day.
Functional description: The reserve supply container is filled

every day at the set time (see page 31). Interim fills are also per­formed if the filling amount is not sufficient for 24 hours.

with enable time: Select this if the feed noise (suction turbine) can

be heard or is disruptive in the living area (also in adjacent
premises).

Functional description: The pellet feed is enabled during a time
period that can be set (see page 29). The reserve supply con­tainer is automatically refilled full at the end of the enable time.

Tip: A complete fill sucks in about 25 kg of pellets. Even if more
pellets are required during the blocked time, there is no automatic
fill and the FireWIN switches off (information message 582).
Therefore, do not select a blocking time that is too long.

3.1 Care of the front window, cladding and keyboard foil

The front window is equipped with a special back ventilation. This ensures that the window remains clean for
a relatively long time. Nevertheless, light deposits formed by ash constituents will form on the inside of the
glass window (inside window). This causes the viewing window to be obscured. This obscuring has no effect

whatsoever on the quality of combustion. The coating can be removed with the door open using water and a
cleaning cloth when the glass is cold. If the glass window is very dirty, moisten the cleaning cloth and dip it in

ash first, then clean.
Tip: Position newspaper or the like to protect the floor against fly ash before opening the combustion chamber

door.
If you wish to enjoy a completely clear view of the fire through the glass window, perform this cleaning about

every 1 or 2 days according to the amount of use during the heating season.
Also clean the cladding and the keyboard foil with a moist cloth as needed. In the event of heavy soiling, use

soapy water or diluted suds (do not use strong cleaners or sharp cleaning instruments).

3.3 Overview of intervals between maintenance

A clean boiler saves fuel and protects the environment. Fly ash and combustion residues must be cleaned off the
pellet flue-connected boiler at regular intervals. Therefore always clean your boiler as required!

In addition to cleaning, annual maintenance is required. This is performed

by WINDHAGER Customer Service or

the customer service PARTNERS and is a prerequisite of the guarantee limitations.
The cleaning and ash removal intervals may be reduced or extended depending on the pellets used (e.g. ash

proportion), the power consumed by the heating system (frequently switching on and off) and the boiler size
of the FireWIN (9 to 12 kW).

The FireWIN is equipped with a cleaning interval display. The cleaning request for the combustion chamber
and burner pot is displayed on the InfoWIN and must be reset after cleaning has finished – see section 2.8.1.6.

Tip: The intervals between maintenance can be determined according to the amount of pellets consumed. There­fore, read out and note down the pellet consumption* on the InfoWIN (section 2.7) in order to determine the
individual intervals that apply to you.

If the level of combustion residue in the burner pot is more than 4 cm above the grate plate, perform cleaning
as follows:

– Lift out the cone using the removal tool – Fig. 128.
– Use the spatula to scrape off the deposits from all sides of the cone, however in particular on the underside.
– Vacuum out the burner pot, remove the primary air pin and carefully clean the holes with a small screw-

driver or drill bit if necessary (holes must be clear).

– Lift the grate plate from below using the removal tool and remove it (Fig. 129), scrape off ash residues from

the top and bottom of the grate plate and from the hole in the middle using the spatula to clean it.

– Use a spatula to scrape the edges out clean all round the inside of the burner pot at the bottom. All sec-

ondary air holes must be clear, clean them with a small screwdriver or drill bit if necessary.

– Remove combustion residues from the burner pot and the grate with a spatula and clean with a vacuum clean-

er. Vacuum the ash out of the primary air tube (in the middle of the burner pot).

Do not open the combustion chamber door during operation. Always switch the boiler off first with the ON/OFF
button and wait until burnout mode has finished. It is essential to let the boiler cool down before cleaning.

3.7 FireWIN reserve supply container

It is necessary to clean the reserve supply container if too much dust has collected on the sides or at the open­ing above the auger, or there are foreign bodies in the reserve supply container. In order to be able to check
this, there must not be any pellets in the reserve supply container. Therefore, allow the pellets in the reserve
supply container to be consumed or, in the case of FireWIN with automated feed, switch off the feed on the
day before (see section 2.8.1.2 Setting the feed operating mode).

Troubleshooting

The FireWIN pellet boiler is self-monitoring during operation. All deviations from normal operation are displayed
on the InfoWIN by information, fault or alarm messages. If one of these messages appears, the LED lights up
red, an information, fault or alarm symbol flashes, an information code is displayed along with a brief descrip­tion in full text – Fig. 155.

Pressing the Info button (Fig. 156) displays the related information text (Fig. 157). To exit the information text
menu, press the Back button (Fig. 157) or wait 10 seconds and the information, fault or alarm message is dis­played again – Fig. 156.

With almost all messages, it is necessary to press the Reset button after rectifying the cause of the informa­tion, fault or alarm message. In these cases, “Reset” is displayed in the menu line – Fig. 156.

If “Reset” is not displayed in the menu line, the boiler starts operating again automatically after the cause of
the information, fault or alarm message has been rectified.

Pressing the Test button changes to the actuator test immediately. This function is only intended for trained
service personnel (directions for setting, see the FireWIN installation instructions).
