Astra P-7 USER MANUAL
seven days a week; it sustains a set air temperature in the room with the help of an integrated temperature sensor; and it even makes the
decision to stop the appliance if unfavourable safety conditions arise: draught of the flue disappears or has fallen substantially, the door
of the stove is opened during the operation; the pellet hopper heats up; or other potentially harmful events happen. In addition, the stove
can be operated by a remote control unit (available by special order).
Only 6 mm wood pellets are used for fuelling the Astra stove. The appliance is not designed to be operated with any other kind of fuel
because other fuels leave a greater content of ashes and slag. The latter then will cause the fire pot to clog, activating emergency stop of
the appliance. In order to enjoy the pleasant heat of the stove without unpleasant interruptions, use only high-quality 6 mm wood pellets
and keep the combustion chamber, fire pot and flue channels of the stove cleaned at all times.
3. TECHNICAL DESCRIPTION
