1.6.1 Dangers and safety measures
Assembly, installation and maintenance may only be carried out by a specialist company.
•Only carry out activities that are described in these instructions.
6 Instructions for UseBSV 20/30 (2.19) © 2023 Brunner GmbH

Electric shock
Work on the electrical installation may only be carried out by a qualified specialist
company.
•The electrical connections are live. This can lead to an electric shock.
•Observe all applicable regulations.
Risk of injury due to scalding
High water temperatures can lead to scalding. Small children or elderly people can be
at risk even at lower temperatures.
•Do not set the hot water temperature of a connected hot water storage tank higher
than 65°C.
Avoid damage to the appliance and resulting hazards
Sprays, solvents or cleaning agents containing chlorine, paints, adhesives etc. can
cause damage to the appliance under unfavorable circumstances.
Under no circumstances should you make any changes to parts or equipment of the
heating system if these changes could impair operational safety.
Risk of frost
If the BSV remains out of operation in an unheated room for an extended period of
time (e.g. during the vacations), the water in the pipes may freeze. Freezing water
can damage the pipes and cause consequential damage.
•Inform the operator about the frost protection of the heating system.
•Install the BSV in rooms with an ambient temperature of 5 °C to 40 °C.
DANGER
This appliance can be used by children aged from 8 years and above and persons
with reduced physical, sensory or mental capabilities or lack of experience and
knowledge if they have been given supervision or instruction concerning use of the
appliance in a safe way and understand the hazards involved. Children must not play
with the appliance. Cleaning and operator maintenance must not be carried out by
children without supervision.
1.6.2 Warnings
Warnings in this document are emphasized by pictographs and signal words.
The pictograph and the signal word indicate the type, the source or causes of a certain action. The neces-
sary measures or calls for action are indicated.
The result or purpose is shown as well. These warnings refer to possible misuse of the system, which seems
likely based on our experience. The residual risks are indicated too.
The residual risks remain:
- despite the means for integration of safety during construction,
- despite the safety precautions,
- despite the additional protective measures.

2 Product description
2.1 Intended use
The BSV 20/30 boiler has been designed and constructed in accordance with the generally recognized rules
of technology and the recognized safety regulations.
The log gasification boiler is intended as a heat generator for closed central heating systems and for hot wa-
ter preparation (in accordance with DIN 4751 and EN 12828).
Intended use also includes compliance with the operating instructions and operating manual associated with
the boiler.
The operator of a Brunner boiler is obliged to regularly service and maintain the sys-
tem in accordance with the Ordinance on Energy Saving Thermal Insulation and En-
ergy Saving Systems Technology in Buildings (Energy Saving Ordinance - EnEV) §
11. We recommend the conclusion of a maintenance agreement between the special-
ist installer and the operator of the heating system.
Non-intended use:
The boiler is not intended to:
- directly heat drinking water;
- burn fuels other than those specified in the technical documentation.
Non-compliant operation may result in danger to life and limb of the operator or third parties or damage to the boiler.
Any other use of the boiler is not permitted. The manufacturer is not liable for any resulting damage to property or per-
sonal injury.
Any other use or modifications to the product, including during assembly and installation work, will invalidate any war-
ranty claims.

2.4 Fuel and water quality requirements
2.4.1 Logs
The BSV 20/30 boiler is designed for the combustion of untreated wood. With the BSV 20/30 boiler, you use
wood in the form of logs (fuel in accordance with § 3 of the 1st BImSchV No. 4). The boiler is also ideally
suited for use in hot water heating systems.
The fuel should have the following properties:
- Dry, untreated logs with a maximum water content of 20%;
- The firewood is split and adapted to the size of the filling shaft;
- The logs should have a length of approx. 50 cm and an edge length of max. 10 cm.
12 Instructions for UseBSV 20/30 (2.19) © 2023 Brunner GmbH

Wood info
Units of measurement when buying logs
Various units of measurement are used when buying logs. The units used every day are
Solid cubic meter (Fm) (Ster)
A solid cubic meter is one cubic meter of wood without cavities. This corresponds to the size of a cube with
edge lengths of 1 m wide, 1 m long and 1 m high.
Cubic meter (Rm)
A cubic meter is one cubic meter of loosely stacked wood, including the cavities. In southern Germany, the
term “Ster” is also used for this.
Bulk cubic meter (Srm)
A bulk cubic meter is one cubic meter of loosely stacked wood with cavities.
Comparison of cubic meters - bulk cubic meters
Conversion factors can be used to compare the different units of measurement. The type of wood, i.e. soft-
wood or hardwood, and the length of the billets must be taken into account.

When using logs, it is essential to ensure that the moisture content is below the legal limit of 25%. 25% wa-
ter content corresponds to a water content of approx. 20%. Freshly harvested wood must always be dried for
one to two years before use - depending on the nature of the storage location and the state of preparation
(sawn or split).
There is a difference between the water content and the moisture content of the wood. The water content
is the mass of water in the wood in relation to the total mass of the wood. The moisture content of the wood
refers to the mass of water in relation to the dry mass of the wood.
If the fuel is too wet, unnecessary emissions are produced during combustion. In order to maintain an opti-
mum water content of 15 to 20 percent in the wood for combustion, the logs must be stored in a well-ventilat-
ed place protected from rain.
The individual logs should be stacked in such a way that air can flow through the wood pile and there is no
direct contact with the ground.
The storage period is one to two years, depending on the type of wood and the ventilation of the storage lo-
cation.
Storing firewood
Storing firewood correctly
1. store your firewood in sunny, well-ventilated areas (south and west sides of your building);
2. create a dry background (pallets or logs);
3. store your firewood at least 15 cm from the ground;
4. your firewood dries particularly quickly when stacked crosswise;
14 Instructions for UseBSV 20/30 (2.19) © 2023 Brunner GmbH

5. cover your firewood with a rain cover after the summer drying period;
6. if you store your firewood under a canopy, a house wall or an airy wooden hut, leave a gap of at least 10
cm between the wood and the building wall for ventilation;
7. if possible, store the day's fuel consumption in your heated room.
1 Canopy or roof overhang 3 Stacked without supports (at the edge)
2 Supports 4 Round timber cross bearing
Principle of drying:
The wood surface is heated (A) and the water evaporates (B). The air absorbs the water vapor from the
wood surface (C), the air cools down (D), falls downwards (E) and escapes (F).
2.4.2 Heating water
Heating water
In modern heating systems, the quality of the heating water has a significant influence on the functionality
and service life of the heating system due to the combination of different heat generators and components
such as high-efficiency pumps or modern sensor technology. For this reason, there are corresponding na-
tional specifications such as VDI 2035 in Germany, ÖNORM H 5195-1 in Austria and similar regulations.
BRUNNER therefore recommends filling and refilling the heating system with appropriately treated water.
Drinking water analyses for the respective supply area can be requested from the responsible water supply
companies.

able; start temperature - see details in the operating instructions) and view of important para-
meters: the current value and its target value: boiler (°C); return flow (°C); combustion chamber
(°C); flue gas (°C); lambda probe (%); output control (%); top buffer temperature (°C); middle
buffer temperature (°C) and many more. (are sometimes displayed differently - depending on the
connected heating control)
Archive

This button provides you with an overview of all operating data (e.g. operating hours, amount of
heat generated, number of burn-offs, etc.)
Flue gas test
You can use this button to set the boiler for a flue gas measurement or enter the date for this.
You will be reminded 3 or 1 day in advance.
You will receive instructions on the necessary preparatory activities.
