The TermaTech TT22 series of wood-burning stoves, including models TT22, TT22S, TT22H, and TT22HS, are designed for intermittent combustion and are CE approved according to DS/EN13240, DS (Danish Standard), DIN (Deutsche Industrienorm), SINTEF (Norwegian Standard), and 15A (Austria). These stoves are not intended for overnight heating.
The TermaTech TT22 series stoves are designed to provide efficient and environmentally friendly heating through the combustion of dry, clean wood. They feature a simplified air input control with a single knob/damper located below the door, allowing users to adjust the airflow between a left (no air input) and middle (maximum air input) position. A start-up aid allows the control knob/damper to be pushed down and completely to the right for faster lighting, returning to the normal position after a few minutes. The door is equipped with a spring that ensures it closes automatically, a feature that can be removed if not required in certain regions. For installation in smoke control areas, a "Damper control unit" must be installed to fix the primary air control at 250mm² and secondary air control at 440mm² in their minimum position.
The TT22 and TT22S models have a nominal heat output of 7.5 kW. The TT22 has a height of 929mm, width of 708mm, depth of 482mm, and weighs approximately 175kg. The TT22S is slightly taller at 949mm, with the same width and depth, and weighs about 208kg. The TT22H and TT22HS models also have a nominal heat output of 7.5 kW. Both have a height of 1093mm, width of 756mm, and depth of 476mm. The TT22H weighs approximately 190kg, while the TT22HS weighs about 250kg.
Average testing values for TT22 models indicate an exhaust gas temperature of 259 °C, an exhaust gas mass flow of 6.2 g/s, and an efficiency of 82%. The nominal heat output is 7.5 kW, with a flue draught of 12 Pa.
The maximum size of logs recommended for use is 50 cm in length and 10 cm in diameter, with firewood having a diameter of 7-9 cm. The maximum filling height for wood is approximately 15 cm from the bottom plate of the combustion chamber, not exceeding the tertiary holes of the rearmost vermiculite/insulation plates.
For safety, minimum distances to flammable materials are specified: 150 mm behind the stove, 450 mm beside the stove, 200 mm behind/beside if mounted at 45° in a corner, and 1200 mm in front of the stove. The stove must be placed on a non-flammable foundation that extends at least 150 mm on each side and 300 mm in front.
The chimney must have a minimum internal diameter of Ø150mm and a minimum height of 3.5 m from the top of the stove to the top of the chimney. All joints and connections must be tight, and the chimney must provide a draught of at least 1.2 mm water gauge (12Pa). A single wall metal flue pipe is suitable for connecting the stove to the chimney, but not as the complete chimney. Any bend in the chimney or connecting flue pipe should not exceed 45°, and 90° bends should not be used.
The TT22 models are available with a combustion air branch, featuring a connecting pipe/spigot of Ø96mm, requiring an air hose of Ø100mm. An adequate air supply into the room is crucial for efficient and safe operation, in accordance with current Building Regulations Approved Document J.
When lighting the stove for the first time, it should be done gently to allow materials to adapt to the heat. Proper ventilation is necessary during the initial heating as the Senotherm varnish hardens, which may cause odors. The painted surface should not be touched when hot.
For lighting, the ashpan must always be closed. 12-15 kindling sticks (2-5 cm diameter) should be placed in a criss-cross pattern at the bottom, with 2 firelighters in the middle. The door should be left ajar (2-3 cm) for 8-10 minutes before closing completely. Once the fire has burned to embers, 2-4 pieces of firewood (2.0-2.5 kg total) can be added, placed parallel to the front of the stove with equal distance to the sides and about 1 cm mutual distance. The control knob/damper should be opened about 2/3 for 2 minutes, then set to about 1/3 open. The exact damper setting depends on the chimney's draught.
Only dry and clean wood with a maximum of 20% moisture should be used. Waste products, synthetic materials, or treated/impregnated materials are strictly prohibited due to environmental hazards and potential damage to the stove and chimney. Firewood should be stored under a roof with good ventilation for 1-2 years to achieve the recommended moisture content. Bio-briquettes can be used, up to 2-3 kg per hour, but energy coke is not recommended due to high sulfur content.
In case of a chimney fire, immediately close all doors, drawers, and dampers to cut off oxygen supply and notify relevant authorities. The stove should not be used again until the chimney has been inspected. If smoke or fumes are emitted, open doors and windows, let the fire die out, check for blockages, and do not relight until the cause is identified and corrected.
The wood-burning stove and smoke pipe should be checked and cleaned once a year by a professional. The chimney must also be cleaned by a chimney sweep at regular intervals. After the chimney sweep cleans the pipe, they can also clean the burner by lifting off the top and using the cleaning hatch.
Daily maintenance is minimal, but thorough maintenance, including cleaning ashes and soot from the combustion chamber and lubricating door hinges and the closing mechanism with copper grease, should be done annually.
The stove's surface can be cleaned with a soft, long-haired brush, vacuum cleaner with a brush, or a duster, always when the stove is cold. Senotherm-spray can be used to cover scratches or damages, ensuring the stove is completely cold before application due to fire hazard.
Jointings should be changed as needed, as they can collapse under heat and lose their sealing ability, which is crucial for good combustion and a clean window. The insulation plates in the combustion chamber, made of Vermiculite, are loosely fixed and can be easily changed when wear surpasses half of their original thickness. Cracks in the insulation do not affect the stove's efficiency.
Glass cleaning should be done when the stove is cold, using TermaTech's glass cleaner. The ceramic glass should be disposed of environmentally. Only original TermaTech parts should be used for replacements due to wear.
Ashes should be cooled for 1-2 days before disposal in a rubbish bin to prevent embers from igniting garbage. If the stove is to be left unused for a prolonged period, it should be thoroughly cleaned, and air controls left fully open to reduce condensation and damage.
