Too short and thick wood logs
lead to an uneven burning
behavior. Too short and thin
wood reduces the burning time.
Only use wood logs according
to specification
During operation, all doors must
be closed to ensure that no false
air can disturb the combustion
process.
The heating-up time can change
due to the cleaning condition of
the boiler, the local conditions,
the used fuels and the weather
changes (low pressure in the
exhaust system.
The boiler operates according to the principle of
the lower burn-up. The control device controls the
boiler automatically and completely.
6.3
Boiler in combinaton mode
(Automatic mode)
If after burning off of the log wood heat will be
required from the boiler or heating circuits, the
boiler operation will start automatically with
pellets.
In combination mode the boiler works as a
automatically fed system. After power up the
boiler is ready for operation.
The start of the combustion occurs automatically
after heat id requested or at a defined starting
point. When at this time the boiler is filled with log
wood, the ignition of the log wood starts with the
pellet burner. After burning off of the log wood and
if there is a heat request, the boiler starts
automatically in pellets mode.
6.4
Feeder system (Pellet)
The fuel is transported from the fuel storeroom by
means of a feeder screw with flat spring stirrer for
burnback protection devices. It then passes
through the drop shaft and the burnback
protection device. The burnback protection device
is driven by a spring-loaded servo-motor. If the
servo-motor has no power supply then the flap
closes independently. Then the plug-in screw
feeds the fuel upwards. These are then directed to
the combustion chamber via a drop level. The fuel
level reached is crucial for the boiler capacity and
the operating condition of the equipment.
6.5
Type of feed
The operation of the pelletfire based on a pulse-
no-pulse ratio which controls the feed system. All
the values are to be set via the menu “Fuel
values” (only available in the service area). These
feed values are corrected by the combustion
control system.
6.6
Combustion air control
Differentiation is made between primary and
secondary air in the combustion air supplied. The
primary air is supplied directly into the embers.
Using secondary air an attempt is made to fully
develop the flame arising from the primary air.
The air supply is supplied via a lateral opening
(underneath the lateral panelling).
The flue gas ventilator is a suction fan and this is
located at the back of the boiler. It generates low
pressure in the boiler. The secondary and the
primary air are sucked out by this low pressure.
The blower is time-controlled by the variable-
speed electronic control. The blower speed is
controlled according to the boiler temperature and
rectified by the lambda control.
6.7
Boiler operation
The equipment goes into operation automatically
when heat is required due to its built-in automatic
ignition.
The heat requirement can be weather-driven, and
can be used in conjunction with a remote sensor
(optional) from any heating circuit. It is also
possible to generate demand using a room
thermometer. The boiler can also switch on the
equipment via its heat requirement.
The control or local data of the boiler capacity can
be adjusted or changed.
The regulation prevents boiler temperatures falling
too low as this can affect the life expectancy of the
boiler.
Boiler temperatures that are too high are not
permitted for operational safety reasons.
Any elongation fissures on the insulation plates or
combustion chamber bricks do not affect their
functioning and therefore do not represent a claim
against the guarantee.
