3.1 General information
Operation only by trained personnel
The product may be operated by trained adults only.
Training may be provided by the heating technician or
our customer service. Please read the associated doc-
umentation carefully in order to avoid errors during
operation and maintenance.
Persons who lack experience and knowledge as well
as children may not operate, clean, or maintain the
product.
Keep children away from the pellet store
Children must be kept away from the pellet store. It is
a good idea to lock the door to the pellet store. The
door handle on the inside of the pellet store must not
be removed. It must be possible to open the door from
the inside in an emergency.
Keep fire extinguishers in a clearly visible location
In Austria, the minimum requirement is an
ABC powder extinguisher with 6 kg. An AB foam extin-
guisher with 9 litres, which produces less damage
when used, is preferable. The fire extinguisher should
be kept outside the boiler room, visible and easily
accessible.
Fig. 3-1: Fire extinguisher
In Germany and Switzerland, fire extinguishers are not
required for heating systems in private residences. In
spite of this, we recommend having one in the house.
Storage of ash
The ash must be kept in non-flammable containers
with covers for cooling. Never put hot ash into the
waste bin!
Emergency stop switch for the boiler
In Austria, heating systems installed in boiler rooms
must be equipped with an emergency stop switch. The
switch must be situated immediately outside the
access door and clearly marked. For boiler rooms that
are only accessible from outdoors, these switches may
also be within the boiler rooms, immediately next to the
access doors.
Fig. 3-2: Emergency stop switch
A single-pole emergency stop switch is integrated into
the boiler's safety chain. When actuated, it interrupts
the supply of combustion air and fuel. The pumps
continue running to cool the boiler.
3.2 Safety devices
Pump safety run, automatic heat dissipation at
overtemperature
If the boiler temperature exceeds 90°C (factory setting)
for any reason, the pump safety run will start. All
heating pumps and boiler pumps that are connected to
the boiler control system are switched on to dissipate
heat from the boiler.
This action prevents the boiler temperature from rising
further and triggering further safety devices such as
the safety temperature limiter.
