Important information
3. Flue
A properly dimensioned flue is required for optimum functioning of the combustion system. The dimensions must be
calculated in accordance with EN 13384-1. See the technical data section for the values required for this calculation.
Please note that in the lower performance range, flue gas temperature may be below 90 °C. Therefore, thermally insu-
lated flues meeting thermal transmittance coefficient Group I requirements according to DIN 18160 T1 or otherappro-
priate, officially approved flue gas systems may be connected to the hearths.
The minimum classification for the flue gas system is as follows:
Temperature class: T400 =nominal operating temperature 400 °C
Soot fire resistance class: G = flue gas system with soot fire resistance
Corrosion resistance class: 2 = suitable for unprocessed wood fuels
We would recommend fitting an energy-saving intake regulator for problem-free operation. This will largely prevent
moisture in the flue, and losses resulting from downtime will be reduced (draught interruptions). If you have a feed
pressure (flue draught) of more than 0.20 mbar, the energy-saving intake regulator must be fitted.
We would recommend fitting the draught limiter outside the flue, around ½ m below where the flue gas pipe enters
the flue.
CAUTION Material losses
The overhaul of existing systems frequently involves over-sized flue cross-sections or flues not designed for
low-temperature operation. We recommend an evaluation by the local building inspector before installing
the boiler system. In this way, appropriate modifications can be made to the flue before system installation.
3.1 Guidance values for dimensioning the flue gas system

4. Boiler room/installation room
Important information for the design of the boiler house, fuel store.
DANGER Injury
The construction and layout of the boiler house, fuel store and chimney must comply with the fire safety
requirements of Approved Document B for high risk compartments.
The configuration of the entire system must comply with the requirements of regional legislation, local plan-
ning, applicable regulations, standards and guidelines.
–The minimum clearances for connections, cleaning and full service must be complied with – see Section 13.1 Mini-
mum clearances for fire protection, cleaning and maintenance on page 14.
–Sufficient ventilation of the set-up area must be provided. See Section 12. Combustion air on page 13.
–The boiler may only be installed in a dry location.
–The boiler may not be installed in rooms that are dusty or humid.
Permissible limit values: Humidity: max. 85 % at room temperature of 25 °C (non-condensing)
Room temperature: +2 to +40 °C
–Do not allow pets or other animals to enter the boiler room or installation room. Install appropriate barriers across
openings.
–In the event of floodwater, switch off the boiler in good time and disconnect it from the mains before water enters
the boiling room or installation room. You must remember to replace all components that come into contact with
water before you put the boiler back into operation.
–Sufficient lighting must be provided for service and full service.
5. Sound emission
The usual measures that are required for all boiler rooms are sufficient to limit the level of airborne noise emitted:
–Heavy doors such as the fire protection doors that are stipulated anyway
–Air supply openings to be kept to an absolute minimum
–Footfall sound insulation to be fitted in the floors of the rooms above
Structure-borne noise:
Structure-borne noise emissions are the primary cause of noise problems on boilers, i.e. the acoustic energy that is trans-
ferred to the building. The main sources of structure-borne noise and the insulation measures required are listed below:
–Squeaking and creaking noises emitted by the fuel auger conveyors (depending on the type of fuel):
Place mineral wool around the delivery chute in the masonry feed-through as a soundproofing measure to prevent
the sound from being transferred to the wall. Similarly, the storage room should be constructed on floating floor
screed so that the conveyor system is acoustically isolated from the building.
–To avoid noises from the chimney or the flue gas pipe caused by the induced draught fan, use a soft non-flammable
soundproofing material (e.g. ceramic cord) when installing the flue gas pipe in the chimney.

ning, applicable regulations, standards and guidelines.
–Pay proper attention to the statics, i.e. from the perspective of the weight of the stored fuel and the weight of the
system.
–Protect the fuel storage room from humidity and moisture.
–Make sure the store is easy to access and fill.
8. Commissioning and operation
DANGER Injury
Unauthorised start-up!
The boiler/system must be started up for the first time by Windhager Customer Service or the customer ser-
vice partner, who will familiarise the customer with system operation and how to clean the boiler by refer-
ring to the operating manual. The flue gas will be measured to verify that the combustion system is working
correctly.
The following preconditions must be met before scheduling the boiler commissioning:
fBoiler installed correctly.
fSystem fully wired up electrically.
fSystem flushed, filled and vented – heat load must be available (e.g. functioning heating system connected).
fSufficient quantity of fuel available.
fThe customer must be present during commissioning.
The initial start-up cannot be carried out if any of these points are not complete. The customer will be charged
for any unnecessary costs arising as a result of incorrect start-up.
Commissioning by Windhager Customer Service or an approved technician with a valid WIN-5 certificate are part
of the warranty requirements.
Register My Boiler
Following the commissioning the customer must register their Windhager boiler(s)online via the windhager.co.uk web
site to validate their boiler warranty.
9. Disposal/recycling
Disposing of the packaging
The packaging material (wooden crate, cardboard boxes, inserts, plastic films and plastic bags, etc.) must be disposed
of correctly in line with the local legal provisions and regulations.
Disposing of components or the boiler
To dispose of defective components or the heating system (e.g. boiler or control system) after the product life has expi-
red, please observe the following information:
fDispose of the items correctly, i.e. separate the parts to be disposed of into material groups.
fDo not simply dispose of electrical or electronic waste with the general waste under any circumstances; instead, use
the public collection points provided for this purpose.
fAs a matter of principle, dispose of items in a way that is as sustainable as possible and that is in line with the cur-
rent environmental protection, reprocessing and disposal technology.

11. System
11.1 Area of use
For heating buildings acc. to EN 12831.
The boilers are designed and approved as heat generators for hot water heating systems with permissible flow tempe-
ratures of up to 90 °C. They are to be installed in sealed systems only. The resulting flow temperature depends on the
relevant operating status and the line losses to the system.
The maximum flow temperature is factory-set at 75 °C.
11.2 Standards
The following European Standard should be followed: EN 12828, according to this standard the following should be
fitted:
a) A closed expansion tank.
b) A reliably functioning safety valve (with max. 3 bar reaction pressure) installed at the highest point of the boiler or
at a non-closable line.
c) A thermometer, a pressure gauge.
d) A low-water cut-off: A low-water cut-off is not required for systems providing up to 300 kW nominal thermal output,
if it can be ensured that a lack of water in the system will not result in excess heating. If the boiler is above the ra-
diators, then a low-water cut-off must be installed.
e) An automatic device for dissipating heat which will prevent the maximum water temperature in the boiler of 110 °C
from being exceeded. The built-in thermal safety device (heat exchanger) should always be used with the thermal
discharge safeguard (accessory FK-060).
11.3 Heating circuits
Several heating circuits:
In-line regulating valves must be installed to permit better regulation of the system. In a building without insulation
(new building, not yet plastered) there is often a considerable difference between the calculated heat demand and what
is actually required.
Motorised mixing valve:
A motorised mixing valve is always required for each heating circuit. A feed control thermostat (FK-001) must be
installed for underfloor circuits.
Boiler start-up relief:
A boiler start-up relief must be installed and connected in all cases so that the circulation pump(s) turn/s off when the
boiler temperature is below 55 °C. This prevents condensation forming in the boiler and extends its service life.
A boiler start-up relief of this kind is included in the MES control system.
11.4 Circulation pump
Since 2013, regulations in Europe require that new circulation pumps satisfy a minimum level of energy efficiency.
The Energy Efficiency Index (EEI) must be observed.
11.5 Return temperature
The PuroWIN requires a return temperature of 55 °C and this must be ensured by means of a return rising group (avai-
lable as an accessory).
In order to achieve good temperature stratification in the heat accumulator or buffer tank, we recommend that the boi-
ler circuit be regulated. If return rising group is used in connection with the stratified charge function (MES INFINITY
buffer load/switching function module), regulation of the boiler circuit is no longer necessary.

11
For the installer
11.6 Heat accumulator (buffer)
Having a correctly sized heat accumulator (buffer tank) is essential for correct operation.
Recommended minimum sizes for buffer / heat accumulator for PuroWIN:
PuroWIN Buffer / heat accumulator
PWPE 60 ≥ 1500 l
PWPE 75 ≥ 2500 l
PWPE 90, PWPE 100 ≥ 3000 l
This recommendation does not replace the appropriate configuration of the heat accumulator / buffer size in relation to
the conditions of the system (such as the coincidence factor, heating requirements of the building, or increased demand
for hot water). Please observe the directives and supply conditions (such as BAFA 30 l/kW (BAFA = the Federal Office
for Economic Affairs and Export Control)) of the respective country at all times!
11.7 Operation by external control
This is only possible with the special function external heating requirement function module INF F05 W (accessories);
the control must fulfil the following demands:
–Minimum boiler temperature and start-up relief:
The consumer pumps (heating circuit and domestic hot water pumps) may only be switched on at a boiler tempera-
ture of more than 60 °C if the burner is on, and will be switched off when the boiler temperature is less than 55 °C.
–Pump over run:
A over run of at least 10 minutes will be observed for all consumer pumps and a minimum heat load must be ensured
during the burnout phase.
–The system specific control settings must be set so that the boiler runs on average for at least 1.5 hours (shorter
operating times cause more contamination of the boiler and greater wear and tear).
11.8 System water
Clean system wate is vital for the faultless operation and long service life of the system. It prevents corrosion damage
in the boiler and in the heating system.
CAUTION Material losses
The chemical composition of the system water must conform with BS 7593:2006 or e.g. ÖNORM H 5195, VDI
2035, SWKI BT 102-01.
Soft water is required during initial filling and refilling after repairs. Feeding lime-rich fresh water should be kept to a
minimum in order to limit scaling.
pH value between 8 and 9.5
The pH value in the heating system must be set to between 8 and 9.5.
a) The chemical composition of the system water must meet the specifications of BS 7593:2006 - Code of Practice
for treatment of water in domestic hot water central heating systems. The condition of the system water must be
checked every 2 years by a heating technician in order to avoid corrosion and sediment accumulation in the heating
system.
b) The pipe lines and heating appliances should be power flushed before the boiler is connected.
c) To protect the boiler from contamination from the heating system, installation of a dirt trap (filter) is required in
old or existing systems (mesh size 0.5 mm) with full service cocks installed in the return line or equivalent magnetic
device.
d) If oxygen diffusion or sludge build-up cannot be prevented in the existing system, the system must be decoupled by
means of a heat exchanger.
e) If antifreeze and anti-corrosion liquids are used they must be in concentrations recommended by the product manu-
facturer and details of the chemical treatment recorded in commissioning documentation.
f) Failure to maintain correct system water quality may invalidate boiler warranty.

12. Combustion air
DANGER Injury
The configuration of the entire system must comply with the requirements of regional legislation, applicable
regulations, standards and guidelines.
The combustion air is drawn directly by the boiler from the installation room; therefore, the installation room has to
be adequately ventilated. The combustion air should be directed to the vicinity of the boiler and must be free from
pollutants (gases, vapours and dusts); otherwise, malfunctions and increased wear (e.g. corrosion) may occur.
The operational reliability of the system must not be impaired by other equipment or systems within the air network
that extract surrounding air. Devices or systems of this kind should not be installed within the air network if at all
possible. If they do have to be installed, suitable measures must be implemented accordingly. Possible options include:
1. Using safety devices to prevent the hearth from being used at the same time as the system that is responsible for
extracting air.
2. Using a safety device to monitor flue gas evacuation.
3. Implementing system-specific safeguards to prevent dangerous negative pressure from occurring when the hearth is
operated at the same time as the system that is responsible for extracting air.
CAUTION Material losses
Malfunctions or complaints occasioned by inadequate combustion air will not be covered by the warranty.
Combustion air supplied directly from the plant room
The combustion air is drawn directly by the boiler from the plant room, therefore the plant room has to be adequately
ventilated. The combustion air should be fed to near the boiler.
Ventilation
All combustion appliances require adequate ventilation to operate correctly. If an appliance is present or installed at
the same time, care must be taken to add purpose provided ventilation in accordance with Approved Document J of the
Building Regulations or the appliance manufacturer’s instructions, whichever is the greater.

For the installer
13.2 Taking into the building and installing
It is best to transport the boiler to the place of installation by lift truck on a wooden pallet. If transporting via stairs or
similar, the boiler should be secured appropriately. For installation dimensions and weights, see Section10 and also
the technical data.
The boiler can be installed directly on a fire-resistant surface and does not require a special foundation.
13.2.1 Removing the crate and base pallet, and transporting the boiler to the place of
installation
The boiler can be removed from the transport pallet by:
a) Using iron rods to roll it off by hand – Fig. 8–Fig. 11.
b) Sawing through the crate with a hand-held power saw – Fig. 12–Fig. 13.
c) Lifting it off by crane using the eye – Fig.14–Fig. 15.
fRemove wooden crate.
CAUTION Material losses
The bottom of the boiler is secured to the base pallet by 2 screws positioned on either side – Fig. 7.
fRemove the screws.
Note!
To make it easier to handle the boiler, a 5/4" pipe can be screwed into the front on both sides – Fig. 7.

For the installer
a) Using iron rods to roll it off by hand
CAUTION Material losses
Before removing the base pallet, screw in all 4 adjustable feet on the bottom of the boiler; otherwise, there
is a risk of causing damage – Fig. 8.
fTo make it easier to remove the pallet, slide some iron rods with a diameter of between 25 and 30 mm under the
boiler (Fig. 9, Fig. 10). Then roll the boiler off the pallet and pull the pallet away – Fig. 11.

b) Sawing through the crate with a hand-held power saw
fRemove the wooden crate surrounding the boiler, e.g. by sawing through it with a power saw.
fTilt the boiler backwards on the base pallet. Then saw through the two front slats at the sides – Fig. 12
fTilt the boiler forwards and remove the remains of the base pallet – Fig. 13.

For the installer
c) Lifting it off by crane using the eye
Alternatively, the boiler can also be lifted off the pallet by using the crane eye on the top of the boiler – Fig.14.
fRemove the 4 self-tapping screws and the cover concealing the crane eye – Fig. 15.

13.2.2 Installing the immersion sleeve and sensor of the thermal discharge safeguard
fThe immersion sleeve and sensor of the thermal discharge safeguard (accessory: FK-060) should be sealed and in-
stalled before you complete the set-up process and install the cladding. This is because the locations are easier to
access at this point.
However, you must not connect the thermal discharge safeguard until the rear panel has been installed – see Section
13.10 on page 45.

13.2.3 Aligning the boiler horizontally
fMove the boiler into position (remember to observe the minimum clearances; see section 13.1 on page 14) and
use the adjustable feet to level the boiler.

13.3 Installing the ash removal device
Fig. 17 Ash removal device (Illustration PuroWIN PWPE 60)
fSlide the ash removal device into the guides on the left-hand side of the boiler (Fig. 18), making sure that the guide
for the ember bed slide is at the top and the one for the ash scraper is at the bottom of the boiler (open the ash
chamber door) – Fig. 19.
fSecure the ash removal device using 4 M8 flange nuts – Fig. 20.
fAttach the bracket inside the boiler to the bottom of the ash scraper using 2 M8x8 hexagon screws – Fig. 21.
