Important initial information for the Technician
The following instructions are available for operation and installation:
Heating expert: Assembly/installation instructions, list of spare parts
System owner: Operating Manual, quick guide, heating instructions
1.1 Safety
The boiler and related accessories are state of the art and meet all applicable safety regulations.
1.2 Please note!
Your boiler and all accessories can be operated using 230 V AC electrical voltage. Improper installation or repair
can pose the danger of life-threatening electrical shock. Installation and repair may be performed only by appro-
priately qualified technicians.
Caution symbols
Please take careful note of the following symbols in these assembly instructions.
Ignoring the warnings identified can lead to personal injury.
Ignoring the warnings identified can lead to malfunction of, or damage to the boiler or heating sys-
tem.
The specified safety requirements are to be followed in accordance with nationally applicable regula-
tions, standards and guidelines.
1.3 Flue
A properly dimensioned flue is required for optimal functioning of the combustion system. Measurement of the
dimensions must follow EN 13384-1. See theTechnical data section (section 4.3) for values required for this calcu-
lation.
Please note that in the permissible performance range, flue gases may be below 160°C. A draught limiter is
needed if the maximum draught is exceeded during operation.
Note: We would recommend fitting the draught limiter outside the flue around ½ m below where the exhaust
pipe intersects with the flue.
Frequently, overhaul of existing systems involves over-sized flue cross-sections or unsuitable flues. We sug-
gest an evaluation by the local building inspector before installing the boiler system. In this way appropri-
ate modifications can be made to the flue before system installation (see section 4.3 for flue calculation
values).

For the Installer
2.2 Taking into the building and installing
The appliance must be taken into the building and installed without subjecting it to significant knocks and jolts,
in order to avoid damaging the combustion chamber and/or the parts slipping. The warranty will be invalidat-
ed if the appliance is damaged due to having been taken into the building and installed incorrectly or if the appli-
ance malfunctions as a consequence of this.
2.2.1 Taking into the boiler room/installation room
The LogWIN may only be transported upright and without cladding and it is easiest to transport using a lift truck
or by rolling on pipes.There is a crane lug on the top of the boiler for transport using hoisting winches. When
transporting via stairs and the such like, the boiler must be suitably secured. Also refer to the technical data in
section 4.4 for transport dimensions.
Tip:: The weight can be reduced by approx. 130 kg by removing parts which are easy to disassemble (e.g. doors,
hook-in plates, burnthrough plates, heating surface cleaning etc.).
2.2.2 Installing in the boiler room/installation room
The boiler can be installed directly on a non-flammable surface and does not require special foundations.
2.2.3 Note before connection
Move the boiler to its definitive installation position and use the set screws to align it inclined slightly upwards
towards the rear.
Tip: Before connecting the heating system, install the insulation, flue outlets and rear wall – see section 2.5.
Please note:
– The minimum clearances for connections, cleaning and maintenance should be observed – see section 2.2.4.
– Set up the boiler only in a dry area.
– Follow local regulations and guidelines regarding the boiler room/installation room.
– Sufficient ventilation of the set-up area must be assured.

2.4 System
2.4.1 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
temperatures of up to 90 °C.
2.4.2 Standards
The following European standard should be followed: EN 12828, this specifies that the following should be fit-
ted:
a) A closed expansion tank.
b) A reliably functioning safety valve installed at the highest point of the boiler or at a non-closable line.
c) A thermometer, a pressure gauge.
d) An automatic device for dissipating heat which will prevent the maximum permitted operating temperature
from being exceeded.The built-in thermal safety device (heat exchanger) should always be used in conjunc-
tion with the thermal process safeguard. In addition, a gravity feed hot water tank with thermal process safe-
guard can also be used.
e) 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 assured that excess heating will not result from a lack of water in the system.
If the boiler is above the radiators, then a low-water cut-off must be installed.
2.4.3 Accumulator tank
Having a correctly sized accumulator tank is essential for correct operation of a wood-fired heating system.The
fuel must always be selected and the heat load of the building calculated. Heating characteristics (e.g. bringing
the hot water tank up to temperature in summer) and the system configuration (ground and/or radiator heating
circuits) should also be taken into consideration.
Tip: Correct amount of fuel – i.e. boiler only ¼ – ½ full at the turn of the seasons.
With domestic water supply plants, a heat dissipation of the smallest possible boiler output must
be assured even if there is a power failure! Failure to comply with this requirement can result in a
thermal overload of the boiler components and invalidation of the warranty.
Rooms that are not heated at times (guest rooms, living areas only used at weekends, etc.) must be
subtracted from the calculated heat load (QH) for the accumulator tank configuration!

1) Correction factor f (Holzenergie Schweiz quality mark): A firewood boiler must be operated at nominal output for about 1 hour after starting. Additionally,
about 0.5 hour is required for heating up. As a rule, it is not possible to operate with the lowest possible output right from the start.The correction factor f
depends on the relationship between the nominal and lowest possible output levels and is individually set for each boiler (assumption: system reaches
nominal output 1.5 hours after starting).

2.4.4 Heating circuits
Several heating circuits:
The total consumed output is not allowed to exceed the nominal thermal output of the boiler. In-line regulating
valves must be installed to permit better regulation of the system. In a building without insulation (new build-
ing, not yet plastered) the calculated and actually required heating requirements often differ to a considerable
extent.
Minimum heat consumption:
It must be possible for the smallest possible boiler output must be continuously dissipated from the boiler dur-
ing operation (see technical data in section 4.4.). Alongside an accumulator tank of a sufficient size, suitable meas-
ures for minimum heat consumption (e.g. never completely closing the manual mixing valve, “consumer cir-
cuit” or radiators that cannot be blocked off, not all radiators fitted with thermostatic valves) must be guaranteed
in each phase of operation.
Having a correctly sized accumulator tank is essential for correct operation.
Mixer valve:
A 3-way mixer valve is always necessary; in conjunction with outside temperature control, there must be a 3-
way motorised mixing valve and an accumulator tank.
Underfloor heating:
Possible with an accumulator tank (with outside temperature control, motorised mixing valve).
Return flow temperature increase:
This is necessary in all systems with an accumulator tank and in old systems with a large volume of water (>
200 l). It is essential for the temperature of the return flow to be kept to at least 45 °C during heating, otherwise
the temperature of the return flow must be increased using a mixing pump or valve.
In order to achieve good temperature stratification in the accumulator tank, we recommend setting the boiler
circuit to a 15-20 K differential by means of the return hold-up group SK RH or SK RH 54. See the enclosed instruc-
tions for the return hold-up group for guidance values for the setting.
Boiler start-up relief:
A boiler start-up relief must be installed and connected in all cases so that the circulation pump(s) are switched
off when the boiler temperature is below 60 °C.This prevents condensation forming in the boiler and extends
its service life.
A boiler start-up relief of this kind is contained in the MES control system.
2.4.5 Heating water
a) The chemical composition of the heating water must meet the specifications of ÖNORM H 5195 Part 1 or VDE
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.
For the Installer
“Komfort” Pufferspeicher: Won’t open in tag editor “Comfort” accumulator tank
In this case, the size of the accumulator tank is based on the long-term heat output, i.e. how long the customer
wants to heat from the accumulator tank.The boiler output does not depend on the heating requirements of the
building, but on the filling chamber size of the boiler and how often the customer wants to replenish fuel to
bring the accumulator tank up to temperature.
A sensible precaution for a buffer solution of this kind is a low temperature heating circuit design (< 35 °C).

For the Installer
With domestic water supply plants, a heat dissipation of the smallest possible boiler output must be
assured even if there is a power failure! Failure to comply with this requirement can result in a ther-
mal overload of the boiler components and invalidation of the warranty.
Technical data of the thermal safety device:
Minimum connection pressure: 2 bar
Maximum operating pressure: 6 bar
Connection dimension: 1/2” external screw thread
2.4.6 Domestic water (bringing the hot water tank up to temperature in
summer)
There may still be fuel in the boiler after the hot water tank has been brought up to temperature. As a result,
measures must be taken to dissipate the surplus energy – see section 2.4.4 Heating circuits; Minimum heat con-
sumption.
2.4.7 Thermal safety device (heat exchanger)
The thermal safety device is used for protection against overheating if the circulation is interrupted (e.g. power
failure) and is not allowed to be used for domestic water heating. See section 2.7 regarding installation of the
thermal process safeguard.
b) The pipe lines and heating appliances should be thoroughly rinsed before the boiler is connected.
c) To protect the boiler from contamination from the heating system, installation of a dirt trap is required in old or
existing systems (mesh size 0.5 mm) with maintenance cocks installed in the return line.
d) If oxygen diffusion or sludge build-up cannot be prevented, the system must be segregated by means of a
heat exchanger.
e) If antifreeze is used, a minimum volume of 20 % antifreeze is required, otherwise corrosion prevention is
not guaranteed.

Connection according to EN 303-5:
2.6 Installing the exhaust pipe
a) Install the exhaust pipe upward to the flue (45° is the ideal angle). Maximum exhaust pipe length to flue 3 m.
b) Avoid 90° bends, 45° bends are better
c) Do not push the exhaust pipe too far into the flue.
d) Do not seal the exhaust pipe completely into the flue. Connection with flexible exhaust pipe inlet into the
flue.The vacuum fan can cause sound transmissions that create noise pollution.
e) The entire exhaust line should be sealed (incl. cleaning aperture) because there can be positive pressure in
the exhaust pipe for a short period during the starting phase.
f) Insulate the exhaust pipe with at least 30 mm insulation!
c) A draught limiter is needed if the maximum draught (see technical data in section 4.4.) is exceeded during
operation.
Note: We would recommend fitting outside the flue around ½ m below where the exhaust pipe intersects
with the flue.
Any section of this exhaust line that only rises slightly (up to 30°) or is horizontal is not allowed to
be more than 1 m in length.
