Important information prior to installation and operation
Carefully read through this information prior to installation and commissioning of the
boiler. If you have any questions contact "SHT Heiztechnik, Salzburg" customer services (Tel.
+43 (0)662 450 444-0).
PROFESSIONAL INSTALLATION & COMMISSIONING
Correct operation of the boiler/installation can only be achieved if installation is carried out by a trained specialist (licensed in-
staller or heating engineer) according to the
recognised technical regulations
. The complete electrical installation must be
carried out by a licensed person or company, and other relevant regulations and standards must be adhered to. Initial commis-
sioning can be carried out as required by company-authorised customer services and SHT partner companies. Prior to initial
commissioning of the boiler by a specialist, the operator of the boiler must ensure the boiler is ready for operation (i.e. electrical
cabling, hydraulic connections, unobstructed and suitable flue, suitable heat extraction and appropriate fuel)
CORRECT OPERATION
Note that the boiler/stove is not childproof (doors, etc.) and must not therefore be operated by children or other unauthorised
and untrained personnel. Training is given by your specialist (installer, authorised customer services or SHT customer services
technician) when commissioning or during servicing.
In the event of unprofessional installation and commissioning, as
well as incorrect operation involving non-observance of the device-specific instructions (as per technical documen-
tation, operating instructions), all warranty and guarantee claims lapse. A return flow boost and the use of a buffer
reservoir as well as a hydraulic calibration of the complete system are essential for correct operation. The heat
consumption must ensure a minimum device running time of 1.5 - 2 hours per combustion cycle at a minimum 50%
of the nominal output.
FUEL and SET-UP
The boiler must be operated by a qualified operator using only the appropriate fuel (fuel requirements in accordance with techni-
cal documentation) and in suitable, dry boiler rooms/installation locations. The fuel store must also be dry and meet the fuel-
specific requirements (see storage room arrangement). The boiler room/installation space and fuel store must comply with the
relevant constructional and safety regulations (especially fire and personal safety regulations).
The storage room must only
be entered after previous ventilation (see also pellet - storage room safety signs) and when the installation has
been switched off and power cut.
FLUE REQUIREMENTS FOR BOILERS
For new or recently overhauled flues the boiler operator must show the authorised heating specialist or customer service techni-
cian, prior to the (initial) commissioning of the boiler, a
valid acceptance certificate of the responsible chimney sweep
demonstrating the suitability and operational readiness of the flue. The flue pipe must be cleared by the operator (no covers or
blockages). A good through flow (sufficient fresh air) must be ensured in the boiler room/installation location. Any existing defi-
ciencies and/or modifications to the flue and the boiler must be pointed out. Because of lower exhaust temperatures in the
transition period the flue must be sealed and be impervious to damp. Smoke and fumes must be able to escape unimpeded into
the atmosphere.
PERIODIC CLEANING AND SERVICING OF THE INSTALLATION
Each heating installation i.e. boiler and all connected system components (e.g. flue, feed system, safety systems) must be ser-
viced and cleaned periodically to ensure correct functioning and efficient operation. Observe the cleaning and servicing require-
ments of these instructions. Our field service engineers and customer services personnel will provide you with the necessary
information. Only a clean and correctly adjusted boiler is an efficient boiler. A coating of only 1 mm of dust on the heat ex-
changer surfaces will increase the fuel consumption by approx. 7%.
Our field service engineers and customer services personnel will provide you with the necessary information.
OBSERVE THE CORRECT ASSEMBLY SEQUENCE
Observe the correct assembly sequence in these instructions. The insulating jacket (sheet-metal lagging including insulation)
must be fitted before the water is connected! Before commissioning fill the boiler with the correct quantity (according to the
standard) of heat transfer medium and ensure a suitable operating pressure is generated in the manifold lines.
OBSERVE THE GENERAL SAFETY INSTRUCTIONS
Ensure that you comply with the requirements of the relevant laws, standards and local fire and building regulations, the heating
system ordinance and all related safety requirements for heating systems, boiler rooms and fuel storage rooms. Further infor-
mation can be obtained from your competent installation company, chimney sweep and building authority.
