3. INSTRUCTIONS FOR USE
All the information for the final user of the device is provided below, with the instructions for day-to-day use. TJ Chimeneas y Bio-
masa is not responsible for inappropriate or incorrect use of the device. For any question or issue, consult your installer or technical
assistance service.
3.1 Fuel
The H90 y H110 thermo fireplaces are are capable of providing adequate thermal comfort via radiators or other sources
heated by hot water and, to a lesser extent, by natural atmospheric air convection using the burning of wood in the fireplace as the
heat source. Nevertheless, not all materials are considered appropriate fuel for use in the device, which, under no circumstances
should be considered an incinerator.
To reach optimal running conditions, we recommend that you use dry wood with a humidity of less than 20% and a drying time of
at least one year for tender wood and two years for hard wood. To load firewood, add three or four logs of 12 to 15 cm in diameter
and 50 cm in length.
Beech wood is the best for the most optimal process of combustion followed by other equally recommendable types of wood
such as oak, chestnut, maple ash, elm, poplar and birch.
The use of eucalyptus and pine is not recommended as they can produce flames that are too long and can lead to premature wear
and tear of the device. Nor is it recommended to use resinous woods or woods rich in aromatic oils (eucalyptus, myrtle) due to
the fact that a greater frequency of cleaning is required and may cause the deterioration of certain parts.
The use of liquid fuel and carbon derivatives, green wood, fresh or damp wood in particular, or salvaged wood (pallets, railway
sleepers, boxes, furniture) is prohibited, as they may cause poorly efficient combustion as well as possible condensation that will
cause the deterioration of the device.
Remember that the quantity of energy released in the combustion process, and therefore, the energy delivered, will depend on
factors like the type of wood used, humidity and quantity. So, while beech wood with a humidity of 10% can deliver around 4.9
kWh/kg, fresh wood with 60% humidity delivers only 2.8 kWh/kg.
3.2 Use of the device
The H90 and H110 thermo fireplaces have the following features, whose correct operation is fundamental for the good performance
of the device in daily use.
Take into account that the different parts of the device made from metal can reach high temperatures, so appropriate precau-
tions should be adopted for use of the fireplace glove included with the device or insulated gloves.

(1) Air vent handle: by pulling it out the vent is opened up to air, which leads to a more lively flame and, therefore, more rapid con-
sumption at a higher temperature. In normal functioning conditions, the air intake should remain semi-open (20 or 30%), while it is
necessary to open it completely for ten to fifteen minutes after lighting.
(2) Glass air vent handle: pull out to open the glass air vent, leading to a current of air to the glass for the self-cleaning effect. Less
markedly, this air acts as a kind of additional post-combustion, as it is slightly pre-heated. In normal conditions, the functioning of the
glass air should remain fully open.
(3) Keep the door open: using a simple turn of the handle it is possible to open or close the door to access the interior cham-
ber of the fireplace to load wood or to clean. Be careful when opening the door not to bang it against the frame of the device. The
device should always be used with the door closed. To open it, do so slowly.
(4) Ash pan: the ash and other residue from the combustion process accumulates in the ash pan drawer. It must be emptied and
cleaned periodically depending on the use of the device.
