6.2.2. POWER SUPPLYING OF A HOT WATER BOILER “PELLETHERM V.4 LT”.
The boiler must be connected to the electrical installation, by observing all technical safety
requirements. The boiler delivery kit includes power supply cable with connector.
The fuel hopper and the automated pellet burner from series “GP xx sc” must be filled with
pellets, in order to be transported by the auger to the burner zone.
6.2.3. SWITCHING ON THE SYSTEM.
The system switching ON is performed through the switch “POWER”, positioned on the hot
water pellet boiler from series “Pelletherm V.4 LT”. In assignment for operation, defined by
the assigned circulations water temperature in the boiler (and by the assigned temperature
from a room thermostat – if connected), the automated pellet burner from series “GP xx sc”
activates and transits to standby mode – pressing the switch “START” to ON position will
start it. In case the switch “START” has been already in position ON the pellet burner will
instantly start. If the system has been operated (or is in the so called “hot reserve”), but the
power supply has been interrupted, then the system will start automatically after the power
supply has been restored.
During initial ignition of the pellet burner and insufficient chimney draught (for
example when the chimney height is not enough or is dirty), smoking from the
cover panels over the boiler’s combustion chamber and convection zone
might occur and/or from the combustion chamber’s door. Therefore it is
recommended to check the closing and sealing of the boiler’s doors and
cover panels, and also to check the chimney condition. The same effect might
occur during the transition seasons – autumn and spring, when the natural
chimney draught is decreased, due to high ambient temperatures.
If the primary (ignition) fuel doze is adjusted incorrectly, smoking through the
boiler’s unsealed parts might occur. In such cases it is necessary to readjust
the ignition fuel doze of the pellet burner –
to be performed by a servicing
technician.
During the fuel ignition a module activates – electrical heater, positioned
under the tilted fire-grate of the pellet burner. This heating element heats the
fuel until it ignites as the presence of fire is indicated by the burner’s photic
sensor. Detailed information about the construction and operation of the pellet
burner from series “GP xx sc” is presented in its manual book.
The automated pellet burner from series “GP xx sc” operates through a
preliminary set algorithm, that is programmed through a specialized software,
installed in the burner’s control module. The operational parameters of the
burner must be adjusted only by a trained servicing technician.
6.2.4. BOILER’S OPERATIONAL PARAMETERS ADJUSTMENT.
The operation mode of the hot water pellet boiler from series “Pelletherm V.4 LT” is directly
defined by the burner’s control module, defining the assigned circulations water temperature
in the boiler. The boiler’s inlet circulations water temperature (return water) also influences
the system operation mode, its reliability and efficiency.
The manufacture company guarantees efficient and reliable operation of the
system: a hot water pellet boiler from series “Pelletherm V.4 LT” and an
automated pellet burner from series “GP xx sc”, ONLY within the system’s
operation range, as presented in Table 4.1 from the manual book.
