2. WARNINGS AND CAUTIONS
ØThese safety guidelines should be read before operating the system, to avoid incorrect usage that might lead
to personal injury or damage to the system.
ØThis boiler must be installed in accordance with the local and international rules in force, only in a well
ventilated and frost-free space, indoor but other than living areas.
ØAll installation, first commissioning, assembly and maintenance, repair, replacement of components must be
carried out exclusively by a fully trained, professionally qualified service technician and must conform with this
manual and the local codes and requirements of the authority having jurisdiction, or in the absence of such
requirements, apply to the EEC directives and European norms (EN).
After commissioning; the repair and maintenance work are under the responsibility of the user and must be done by a
qualified service technician.
ØThe boiler should not be used for purposes other than specified in this booklet. Incorrect installation,
commissioning or use, can cause a fire or explosion which may result in property damages, personnel injury, or loss
of life.
ØBoiler is designed for hot water operation only (max 80 °C) and the system pressure must be according to
the limited operating pressure specified on the boiler name plate (3 bars [43 psig] standard). Heat transfer medium is
water.
ØBoilers must be fired by fuels specified in this manual. Use only those fuels recommended by us - wood
pellets pursuant to EN 14961-2, Class A1+ A2 (Ø 6 mm). Only in this way low-emission, economic, and trouble-free
operation of your pellet heating system can be ensured. Non-compliance will result in voiding of the guarantee.
ØBoilers must be fired only by its original burner and screw feeder.
ØRecommendation: For long burner running times, in order to reduce the start-stop emissions and to reduce
maintenance costs, the boiler should be fitted with a buffer storage tank, thermos-siphon buffer storage tank or
combination storage tank. In practice, buffer capacities between 40 and 75 liters/kW have proven successful. Be sure
to take into account the country-specific requirements regarding buffer storage tanks.
ØThis heating boiler is adjustable within an output range of 30% to 100% of the rated output. The units
should be operated if possible, in the middle and upper output range (adjusted to the respective heat requirement), in
order to avoid unnecessary emissions in low load operation.
ØIf technical changes are undertaken independently, we assume no liability for damages that may result
thereof.
ØAny procedure undertaken by persons other than those authorized by us, and non-compliance with these
general considerations and the safety notices described by local standards and/or EN standards, codes and directives,
shall result in immediate voiding of any warranty claim as well as the guarantee.
ØDamaged parts and unit components must be replaced only with original replacement parts.
ØThe generally applicable rules of heating technology must be observed for protection against Legionella.
ØPlease note that you must observe the prescribed servicing intervals during the warranty period!
ØThe mandatory maintenance of the system must be done by authorized technicians at least two times a year
but no later than when reaching 1500 hours of operation. If no service is performed, the warranty claim or the
warranty is void!
ØIn the course of maintenance work on the pellet heating system, all wear parts are replaced and billed.
ØForeign bodies in the fuel can result in damage to the system and guarantee will be void.
ØIf there is no local rules, the regulations pursuant to A-Norm M 7136 (Transport and Storage Logistics) and M
7137 (Pellet Storage Requirement) must be observed.
