6.5. Adjustment of combustion air
ARTE ® MENTOR fireplace gives you the opportunity to adjust the primary combustion air intake by the LCD control
panel. The control device controls an electric motor where the changes that are done on the control panel are
transferred to the combustion air intake damper. To prevent overheating, they are equipped with a sensor which is
placed in the thermowell of the water jacket where in the case of overheating the device closes the supply of
combustion air.
- Automatic regulator of the heating circuit for water heating fireplace with air
intake control (RT-08G)
The regulator controls the intensity of the combustion in the fireplace by adjusting the combustion air damper, so as to
maintain the water temperature in the fireplace to a desired, predetermined level.
This results in enabling the regulator, in a second phase, when the water reaches a predetermined temperature to
activate the pump of the heating circuit (HC) as well as the domestic hot water circulating pump (DHW).
It regulates not only the start and end of the circulators but it also has the option, when the user wishes it, to give a
periodic priority to the DHW pump in correlation to the HC pump. Recurrent priority means that it alternately activates
the HC pump for 45 seconds and then suspends it for the next 4 minutes thus resulting in heating the DHW faster.
It also has the option to shut down another heat source (e.g. gas boiler) when operating the fireplace or to command
an additional pump or motorized valve (solenoid) with a maximum power of 500W.
!
The regulator has an ANTI-FREEZE system which protects the heating circuit from potential freezing when the
measured temperature is below 4
o
C, by automatically activating the HC pump.
!
The regulator has an ANTI-CLOG system which operates the heating circuit pumps for one minute per week
during the period that the device is not used.
The regulator is equipped with its own emergency power source so a power supply interruption up to 8 seconds would
not impair its smooth operation. In case of an outage longer than that, an uninterruptible power supply device can be
used (UPS). For safety reasons, if the regulator is not receiving power, the damper closes completely and is
automatically placed in the rest position (fully closed).
