TECHNICAL CHANGES We continuously develop and improve our boilers. The
information in this edition was correct at the time of going to
press. All details in these instructions on standards, regulations
and worksheets should be checked before use and should be
compared with the regulations applying locally at the site
where the boiler is installed. We reserve the right to make
changes which may then deviate from the technical details
and illustrations in this operating manual.

2. Safety instructions
2.1 Intended
use
BASIC PRINCIPLES FOR THE CONSTRUCTION OF THE SYSTEM
BASIC PRINCIPLES The heating system was built using state of the art technology
and conforms to recognised safety regulations. Nevertheless, its
use still poses the risks of injury or death of the user or a third
party, and of adverse effects upon the heating system itself or
upon other material goods.
Have your specialist heating company provide you with a detailed
explanation of the operation of the heating system.
USING THE HEATING SYSTEM Only use the heating system if in perfect condition. Use it properly,
as intended, and be aware of safety concerns and the dangers
involved under observance of the operating manual. Have any
faults which could impair safety fixed immediately.
BASIC PRINCIPLES REGARDING THE CONTENT OF THE OPERATING
MANUAL
SCOPE The content of this operating manual is intended exclusively for
the planning, installation and operation of the heating system
TDA Thermodual. Any further implementation of applicable
standards, for example with regard to the installation of the
heating system (pipework, etc.) is not part of this operating
manual. SHT Austria does not assume any liability for this.
APPLICATION OF THE
HEATING SYSTEM
The heating system TDA Thermodual is designed for the use
of wood pellets conforming to EN Plus standard and split logs
(w<30 %); materials not suitable for combustion are: wood dust,
wood chips, solid- liquid- or gaseous fossil fuels, etc. In addition
no PVC-containing waste products, cardboard containers, paper,
coated wood, etc. must be burnt; the wood must be free from
foreign bodies (nails, screws,etc.). See Section 3.4 for more
details on fuels. Fuels prepared from painted, varnished or coated
wood should not be used. Any other application is considered
improper use. The manufacturer will accept no liability for any
damage resulting from improper use. The operating company/
owner bears sole responsibility in such cases. Proper use includes
adherence to the installation, operation and maintenance
requirements specified by the manufacturer.
Modification of the specified operating values will affect the
heating system’s control program and could lead to malfunctions.
Only trained maintenance and operating personnel may
undertake modifications to the operating values.
UK SMOKE CONTROL AREAS The TDA Thermodual models have been recommended for
exemption under Section 21 of the Clean Air Act 1993 for use in
smoke control areas when burning wood logs or wood pellets
which are selected in accordance with the recommendations on
fuel in this manual.

Contact with the hot surfaces of the boiler can lead to burns. Wait until the boiler has cooled
down before touching uninsulated components.
Danger of asphyxiation and explosion from carbon monoxide. When the boiler is in operation,
carbon monoxide escaping from opened cleaning or inspection hatches can pose a danger of
asphyxiation or explosions. Do not leave these open any longer than necessary.
Opening doors and lids to hot combustion residues can pose the danger of fires. Keep the
openings closed during operation, and when performing cleaning work, allow the combustion
residue to cool down before you place them in a fireproof container.
The boiler weighs over 750kg. If the boiler is dropped during transport, persons can be
seriously injured and the boiler can be damaged. Make sure that you use appropriate lifting gear
when transporting, moving and installing the boiler.
When working on the pellet grate, cleaning turbulators, and pellet delivery systems, hands
or arms could be injured. Turn off the main power switch when working on these components.
