Introduction

1. The boiler and all associated equipment
must be installed and used in accordance
with the installation design, all applicable
legal regulations and technical standards and
with the manufacturer’s instructions. The
boiler may be used only for the purpose for
which it is intended.

2. The boiler may be installed only in an
environment, which it is designed for. If the
same person who installs it delivers the boiler
to the client, he must give the user also all
accompanying boiler documentation (in
particular User Guide, Service Book, etc.).
Until the boiler is put into service, the original
packaging must be kept in case the boiler
has to be transported again.

3. After installation, the boiler must be
put into operation by a service organization
authorized by the manufacturer.

4. The boiler complies with regulations
applicable in the European Union. When
used in the conditions of countries outside at
EU, any deviations from local regulations
must be identified and rectified.

5. In the event of a defect call an
authorized manufacturer’s service
organization – any unauthorized interference
may damage the boiler (and possibly also
associated equipment!).

6. The service technician putting the
boiler into operation for the first time must
show the user the various parts of the boiler
and how to control the boiler, with the boiler
safety elements, their signals and appropriate
user reaction to them, with fundamental parts
of the boiler and their controls. If the same
person who installs it delivers the boiler to the
client, he must make sure that the original
packaging is available in case the boiler has
to be transported again.

7. Check the delivery for completeness.

8. Check whether the model and type supplied
is suitable for the required use.

9. Whenever you are not certain how to
control the boiler, study appropriate
instructions in this Operation and installation
Guide carefully and proceed accordingly.

10. Never remove or damage any markings
and signs on the boiler. Keep the original
packaging until the boiler has been put into
service, in case the boiler has to be
transported again.

11. When making any repairs, only original
parts must always be used. It is forbidden to
make any changes to the boiler’s internal
installation, or to interfere with it in any way.

12. At the end of its life cycle, the boiler its
package and its parts must be disposed of in a
way avoiding harm to the environment.

13. The manufacturer disclaims any
responsibility for damages caused by the
failure to abide by:

• The conditions stipulated in this Operation
and Installation Guide

• Applicable regulations and standards.

• Sound installation and operation

procedures.

• Conditions stated in the Warranty
Certificate and the Service Book.

• The conditions stipulated in this Operation
and Installation guide

Situations might occur in practice, when the
following essential precautions must be taken:

Shut the boiler down every time when here
are any (even temporary)

9

Flammable or explosive fumes present on the
premises from combustion air are supplied to
the boiler (e.g. from paint when painting,
laying and spraying molten substances, from
gas leakage, etc.).
If it is necessary to drain water from the
boiler or from the whole system, the water
must not be dangerously hot;

If there is any leakage from the boiler’s heat
exchanger, or when the exchanger is clogged
up with ice, do not attempt to start up the
boiler until normal operating conditions have
been restored;

Ensuring safety of equipment and people

The boiler (and all accessories) complies with
the requirements of EN 303 – 5 its updates
and all relevant European standards.

In order to run and operate the boiler in
accordance with the purpose for which it is
designed in actual conditions of use
(hereafter referred to only as use), it is
necessary to abide also by additional
requirements the most essential ones of
which (i.e. those which must not be omitted)
are found in the related regulatory
documents.
In addition to the above-mentioned
documents, it is necessary when using the
boiler to proceed in accordance with this
Operation and Installation guide and the
accompanying boiler manufacturer's

Operating Instructions

ARTA Series Boiler – General features

• ARTA series solid fuel fired boiler is

designed for heating both residential and
industrial buildings.

• Besides professional installation,

precondition for correct functioning of the
boiler is the required chimney thrust and
correct operation.

• ARTA series solid fuel fired boiler is

designed for heating systems, which are
suitable for forced circulation systems only.

• ARTA series boilers are available in four

output series: 20 kW up to 43 kW.

• Attached to the boiler body are sheet

metals covers are fitted on the inside with
thermal insulation.

• To ensure that the boiler functions correctly

and runs economically, it is important that
its nominal output is equal to the thermal
losses of the heated premises.

• Choosing a boiler of insufficient output will

result in inadequate heating of the
premises, and thus failure to provide a
heating comfort.

• Choosing a boiler of unnecessarily high

output will result in the boiler not running in
full output, and as a consequence in tarring
and dewing.

Recommended fuel

Recommended fuels for ARTA boilers are
coal, coke and firewood.

Optimal coal and coke granularity is 24 – 60
mm.

Optimal firewood size is logs of diameter 40 –
100 mm. Their length will depend on how
many kW size.
