This documentation should be read carefully before installing and commissioning
the heating system. In the event of any confusion please contact the technical support
department of "Lohberger Heiztechnik" (Tel. +43 (0)662 450 444-0).
"PROFESSIONAL INSTALLATION & COMMISSIONING":
Correct operation of the boiler / system is only ensured if it is installed by a trained and qualified specialist (licensed
plumber or heating engineer) in accordance with recognised industry standards. The entire electrical installation
should be installed by a licensed company. VDE, ÖVE and other relevant regulations and standards are to be adhered to.
The initial commissioning process can be implemented by authorised customer service departments or Lohberger Heiz-
technik partners and is conducted upon request. Before the boiler is operated by a specialist for the first time the opera-
tor of the system must ensure it is ready for use (i.e. electrical wiring, hydraulic connections, suitable chimney, suitable
heat dissipation and appropriate fuel).
"CORRECT OPERATION":
Please note that the boiler / system has not been designed to be child-proof (doors, etc.) and it should therefore not be
operated by children or any unauthorised or untrained persons. Training is provided by your specialised technician (in-
staller, authorised service department or Lohberger Heiztechnik service technician) during commissioning or maintenance.
In the event of non-professional installation and commissioning, as well as improper operation contrary to
system-specific requirements (according to technical documentation, operating instructions, etc.), it shall
result in expiration of any warranty or guarantee claim. The use of a return riser, a storage tank and hydrau-
lic adjustment of the overall system are imperative for proper operation. Heat intake must enable a minimum
system running time of 1.5 - 2 hrs per combustion cycle at min. 50% of nominal output.
"FUEL and INSTALLATION":
The heating system should only be operated with the designated fuel (fuel requirements according to the technical docu-
mentation) and in suitable, dry rooms/installation areas. The fuel storage area must also be dry and fulfil the specific fuel
requirements (see storage area configuration). The boiler room/installation area and fuel storage area must comply with
the applicable building and safety regulations (particularly fire and personal safety regulations). The storage area
should only be entered after ensuring sufficient ventilation (also see pellet storage area safety signs) and
making sure the system is switched off and fully disconnected.
"CHIMNEY REQUIREMENTS FOR HEATING SYSTEMS":
When dealing with new or recently renovated chimneys the operator of the heating system is required to present the
commissioned heating contractor or service technician, without being requested, a valid inspection certificate from
the responsible chimney sweep prior to the (initial) commissioning phase in order to demonstrate the suitability and
operational readiness of the chimney. The chimney is to be made freely accessible by the operator (no covers or obstruc-
tions). Good ventilation (sufficient supply of fresh air) in the boiler room/installation area is to be ensured. Reference
should be made to any existing defects and/or changes to the chimney and heating system. If possible, the relevant
chimney sweep should also be in attendance for the initial commissioning phase of the heating system. Due to lower flue
gas temperatures in the transitional period the chimney should be constructed in a moisture-resistant and leak-proof
manner. Smoke and/or flue gases must be channelled unhindered into the open air.
"PERIODIC CLEANING AND MAINTENANCE OF THE SYSTEM":
All heating systems, i.e. fireplaces, including all of the associated components (e.g. chimney, conveyor system, safety
systems, etc.) must be subjected to periodic maintenance and cleaning procedures in order to ensure their functionality
and operating efficiency. Please refer to the cleaning and maintenance instructions in this manual. "Lohberger Heiz-
technik" and Lohberger Heiztechnik partner companies offer their customers a comprehensive service / mainte-
nance contract and would be happy to undertake this important task. Further information is available from our sales
staff and customer service representatives. Your local chimney sweep will be happy to clean the fireplace. Only a clean
and correctly adjusted boiler is an economical boiler. A lining of just 1 mm on the surfaces of the heat exchanger increas-
es fuel consumption by approx. 7%.
Further information is available from our sales staff and customer service representatives.
OBSERVE THE CORRECT "ASSEMBLY SEQUENCE":
Observe the correct assembly sequence in this manual. The insulating jacket (metal cladding including insulation) should
be assembled before the water-side connection is established! Before commissioning the heating system it should be filled
with heat transfer fluid in accordance with the relevant standards and a suitable operating pressure established in the
distribution pipes.
OBSERVE THE "GENERAL SAFETY REGULATIONS":
Ensure compliance with the applicable laws and standards, as well as compliance with local fire and building safety regu-
lations, the heating systems ordinance and all related safety requirements for heating equipment, boiler rooms and fuel
storage areas. Your local installation company, your chimney sweep and your local building authorities would be happy to
provide you with further information.
