1. How can I keep the glass clean By making a point of using dry clean wood in the appliance Wood that is too damp immediately gives off lots of ash Make sure the seals are in good working order Any air seeping out around the glass part of the door will cool the air resulting in the appliance not burning cleanly How much wood will use That depends entirely on how you heat your room what sort of appliance you have and the size of the room you are heating As a general rule an appliance used in accordance with our guidelines no air under the fuel topped up once an hour each kg wood produces an output of about 3 kW In an averagely insulated house the general rule is that in a room of 80 m you need an appliance with an output of around 7 kW For each subsequent 10 m add on 0 6 kW In a relatively well insulated house the general rule is that in a room of 80 m an appliance of 5 5 kW is adequate and for each subsequent 10 m you need to add a further 0 4 kW 24 Instructions for use UNILUX 6 40 BARBAS Can a wood burning appliance fireplace insert be connected to a central heating installation The Barbas range does not have any appliances that can be connected to central heating installations We do not advise attempting it How do know if l m heating correctly Follow the instructions in this manual The flames should play softly across the wood and the wood should burn evenly Once the fuel has bee2.
