Chimney Fire - TermaTech TT20 Montage- Und Bedienungsanleitung

Chimney fire

In case of chimney fire the doors, drawers and damper of the wood-burning stove must be closed
immediately in order to shut of the supply of oxygen. The relevant authorities must be notified if
necessary. The stove must not be used until the chimney has been inspected.
Kindling is the designation for finely split wood/sticks that are about 20-30cm long and have a
diameter of 2-5cm.
Wood like birch, beech, oak, ash, elm, pine wood and wood from fruit trees is all suitable for
splitting into firewood.
Waste products like pressure-treated wood, chipboard, coloured brochure or glossy paper must
not be used in a wood-burning stove. They develop hydrochloric acid or heavy metals which
cause a lot of damage to the stove and the environment.
Firewood should have a diameter of 7-9 cm and be no more than about 30 cm long, otherwise
it will get too close to the side of the stove (at the CE-testing firewood at a length of 28 cm was
used). The most important thing for good combustion is that the wood is dry (15-20% moisture).
If the firewood is too wet it is difficult to get it to burn, the chimney draught is nonexistent, there
is a lot of smoke and the exploitation is lower as the water has to evaporate first. Furthermore
there may be damage to the stove and the chimney in the shape of shining soot and tarry depo-
sits. At worst it can cause a chimney fire.
If the firewood is too dry it will burn too quickly. Often the gasses in the wood are released faster
than they can burn and some go unburned through the chimney. This also gives lower exploita-
tion and harms the environment.
So it is a balance that is quite easy to find with a little practise. See also below under Storage.
Bio-briquettes can be used, but they develop a lot of ash and dust. Put in max. 2 kg per hour.
PLEASE NOTE - Bio-briquettes can NOT be used in Smoke Control Area.
Energy coke must not be used as it contains a lot of sulphur which wears on a stove, the chim-
ney and the environment. The life of stove and chimney will be significantly reduced by using this
firing type and the right to claim compensation for the product is void.
Storage of the firewood is best under a roof, however with good ventilation, e.g. in a carport
or under a shed roof. Place the wood on a wooden pallet or the like so it is free from the ground.
Fresh wood that has been sawed and split must be stored for about 1-2 years this way until the
moisture in the wood is down to 15-20%.
The ashes can be put in the rubbish bin for garbage collection. The ashes should always have
cooled for 1-2 days before it is put in the rubbish bin, as there might still be embers that can light
garbage or a garbage bag.
Regulation and smoke damper
If one is fixed in the chimney it should not close of more than 80% of the internal diameter of the
chimney.
MALFUNCTIONS
If problems should occur with the use of the stove the cause can possibly be found below. If not,
then you are always welcome to contact your dealer.
The stove is difficult to control – it burns too fast
If the stove is new, then check that the directions have been followed. If the stove is more than 1
year old or if it has been used heavily, then the jointings may need to be changed. If the jointings
sit for too long the heat makes them lose their ability to keep the stove sealed. If there is heavy
draught in the chimney it may be necessary to fit a damper in it.
The stove has poor draught after installation
Check that the mounting instructions have been followed. It is especially the conditions sur-
rounding the chimney that may cause problems. Are diameter and length okay, is it sealed, are
smoke pipe and junctions sealed? Is the cleaning hatch sealed? You may need to contact a chim-
ney sweep to remedy the problem as the chimney may be blocked.
Smoke and soot smell
This can be caused by down-draught in the chimney and most often happens in specific wind
directions. The chimney may be too short for the ridge or trees may have grown and are creating
turbulence.
Remember not to open the door while there are flames.
