Ariterm KMP Uno - Initial Boiler Operation

PELLET BOILER UNO
ARITERM SWEDEN AB Installation Instructions - 2008.05.21 - 14/28
Operation start
To fill the system
Before starting up, a closed system must be filled up to a water pressure of 0.1 bar
higher than the static pressure = the height difference between the highest radiator
and the expansion chamber.
Example:
Highest level 5 m = 0.5 bar + 0.1 = 0.6, which gives a manometer pressure of 0.6
bar at cold boiler.
Systems with open expansion chambers are filled until water flows out the overflow
pipe.
Pellet burner
Burner settings and maintenance are described in detail on the following pages.
Flue gas temperature is choosen by means of the burner output with regard to
chimney’s design and condition.
As a start value, set the fuel feeding (pot 1) so that the screw turns approx. a half
revolution(KMPstandardscrew1.7or2.3m).Thefan(pot3)canbesetbetween
150 and 180 VAC.
Switch
The UNO boilers 6 and 9 kW are equipped with a switch on the switchboard panel.

The output is also automatically controlled in this position.
Thermostats
It is recommended to adjust the burner thermostat to switch off at a boiler
temperature of 80 - 85˚C. The electrical thermostat is set 20 - 30˚C lower to make
electrial heating start in case of an unintential burner breakdown but not to switch
on at normal operation.
