1 Product description
1.1 General
The Lilla Frö stove has been developed to work as a primary heat source. The stove’s high
level of efficiency, in combination with automatic operation, means that the stove replaces up
to 80 % of the heating in a normal family house with electricity as heating source. The stove
is designed for firing with wood pellets and requires an electrical power supply. In event of a
power cut, the stove requires a reserve power source from an uninterruptible power supply
(UPS) or a petrol driven generator in order to function.
The integrated convection fan distributes the hot air around the house, for best effect the
stove should be centrally located on the lower floor of the house. The room temperature is
easily set from the control panel. During thermostat operation the stove automatically ignites
and extinguishes the stove when the set temperature is reached.
It is filled with pellets by opening the hatch under the stove’s top panel. The spacious hopper
means that the stove only needs to be refilled a maximum of twice a day. The filler hatches
and door are equipped with safety switches. Two safety thermostats are mounted together
with the switches in a safety coil to prevent overheating and back-fire.
Lilla Frö can be installed without a traditional chimney if your home does not have one.
The solution that makes this possible is called Ariterm Arrow, which is a patent-pending, fan
controlled, flue gas duct that goes straight out through the wall.
The stove must not be used as an incinerator and must only be fired using wood pellets
acc. to EN 14961.
NOTE!
The stove’s surfaces on and around the glass become extremely hot.
