Kindling Wood / Firewood Sticks
Kindling wood refers to finely split wooden sticks with a diameter of 2-3 cm. Wood types such as birch, beech, oak, ash, elm,
coniferous trees, and fruit trees are all suitable for use as kindling wood.
Fuel / Prohibited Waste Products
Only dry and clean wood should be used for burning in the wood stove. Wood types like birch, beech, oak, ash, elm, coniferous
trees, and fruit trees are suitable as firewood in the wood stove. The moisture content should be between 12 and 20%.
The maximum size of firewood pieces must not exceed the width of the combustion chamber minus 4 cm in length (see the width
of the combustion chamber in section 10.), as this would bring the wood too close to the sides of the stove. This can result in poor
gasification, sooting, and damage to the insulation plates. If the wood is too wet, it's difficult to get it to burn properly. Chimney
draft may be insufficient, causing heavy smoke and sooting of the glass, and it leads to lower energy efficiency as the water in the
wood needs to evaporate first. Additionally, it can cause damage to the stove and chimney in the form of glossy soot and tar
deposits. In the worst case, this can lead to a chimney fire. If the wood is too dry, it will burn too quickly. The gases in the wood
are released faster than they can burn, resulting in unburned gases going up the chimney. This also leads to lower efficiency and
environmental damage.
Burning with waste products such as plastic, pressure-treated wood, particle boards, colored brochures, glossy paper, or other
treated materials is prohibited, as these materials are both environmentally harmful and emit harmful substances such as
hydrochloric acid, dioxins, and heavy metals, which can cause significant harm to humans, animals, the stove, chimney, and the
environment. Warranty and claims rights are void if the above-mentioned materials are burned in the stove.
Energy coal (coke) must not be used in the wood stove, as it contains high levels of sulfur, which can cause significant wear on the
stove, chimney, and the environment. The lifespan of the stove and chimney will be significantly reduced when using this type of
fuel, and the product's warranty will be void.
Note: The stove has not been approved/tested for use with wood briquettes/bio briquettes by the Danish Technological Institute.
Lighting/Ignition and Continuous Firing
The instructions described/used from steps 1 to 6 here are the same as those applied during the testing and approval of the stove
by the Danish Technological Institute, Aarhus (TI). The fuel used for testing is birch wood. To protect the environment and ensure
you get the best performance from your new Termatech stove, it's important to follow these instructions.
1. Push the air control handle all the way to the right. On some models, the air control handle might need a slight downward
push to move it all the way to the right. The ignition/start-up air is now adjusted to maximum (See Figure 1.1).
Figure.1.1.
2. Arrange 12-15 kindling sticks at the bottom of the stove. The sticks or wood pieces should have a diameter of 2-8cm and a
length of about 22cm, with a total weight of approximately 1.7kg. Start with the 2 largest pieces of wood at the bottom
and finish with the sticks laid crisscross like a log cabin. Place 2 firelighters on top (See Figure 3.1). We recommend using
Bio-firelighters that produce a strong flame and have a long burning time. This lighting/ignition method is referred to as
the Top-Down method.
3. Ignite the two firelighters (See Figure 3.1) and leave the door slightly ajar using the small bracket (only on TT21) in the
upper right corner of the door (See Figure 3.2). On TT20 models, you can simply leave the door slightly ajar. Keep the
door ajar for approximately 3 minutes before closing it completely. Once the door is closed, set the air control handle to
100% combustion air (full secondary air) (See Figure 3.3).
