7.2 WARNINGS ABOUT PELLET
Pellets in suitable standarts like 6-8 mm in diameter, 6-30 mm in length, made of
wood with shells peeled, moisture content 10% -15%, minimum 3500-4000 kcal
heat value, no chemicals and additives added should be used in the boiler.Our
company is not responsible for any faults and inefficient operation in case of
using improper pellets as fuel.It is important to make sure that there are no
foreign substances in the pellet.Damage caused by foreign material coming out of
the pellet is not covered by the warranty.
Pellets made of chipboard and MDF powder should never be used in the boiler.
7.3 USING PRECAUTIONS
When the boiler water temperature reaches 30 ° C in burning, the circulation pump is
activated. This prevents both unnecessary electricity consumption and prevents the boiler
from the water vapor damage caused from heating up quickly to sweat. At the same
time, it prevents the circulation of unheated water to the radiators.
The boiler water temperature continuously decreases when the fuel is
exhausted and the circulation pump is deactivated when it reaches 30 °
C. When the boiler water temperature drops down to 25 ° C, all
functions stop.
The fan is automatically switched off when the boiler water temperature
reaches at the set thermostat limit. The fan starts to work again when the
boiler water temperature falls below 5 ° C from the set temperature.
You can control activation and deactivation of the circulation pump, fan and
reductor from symbols on LCD sceen in control panel.
As long as the boiler is not unplugged, the circulation pump will
automatically switch on for 3 seconds in every 25 hours. This prevents faults
that may occur in the pump in case of not using for a long period of time.
ATTENTION!!! In case of power cut, the boiler water may
increase to extreme boiling temperature because it is difficult to control
the high heat in the bunker due to circulation pump stop. For this
reason, please follow the below procedure during a power cut:
