Operating instructions
Please note that HETAS Approval only covers the use of wood in the stove
and approval does not cover the use of other fuels either alone or mixed
with other fuels, nor does it cover instructions for the use of other fuels.
Fuel
The stove is designed and approved in accordance with EN 13240 and NS 3058 for stok-
ing split, dried rewood. The rewood must have a water content of 15-22% and its
max. length should be the length of the combustion chamber minus 50-60 mm.
Stoking with wet rewood causes both soot, environmental pollution and bad fuel
economy. Freshly cut wood contains approx. 50-70% water and is thoroughly unsuitable
for stoking. Count min. 1 year of storage time for newly cut wood before using.
Wood with a diameter of more than 100 mm should be split. Regardless of wood size, it
should always have at least one surface area free of bark.
We do not recommend stoking with painted, laminated or impregnated wood, wood
with a synthetic surface, painted refuse wood, chipboard, plywood, domestic waste,
paper briquettes and pit coal, as this will produce malodorous smoke, which could be
poisonous.
When ring with the above-mentioned items and amounts larger than those recom-
mended, the stove is subjected to a larger amount of heat, which results in a higher
chimney temperature and lower eciency. This can result in the stove and chimney
becoming damaged and would void the warranty.
The caloric value of the rewood is closely connected to the moisture level of the
rewood. Moist rewood has a low heat value. The more water the wood contains, the
more energy it takes for this water to vaporise, resulting in this energy being lost.
ONLY USE RECOMMENDED FUELS
The following table shows the caloric value of dierent types of wood, which have
been stored for 2 years, and which have a residual moisture of 15-17%.
Wood Kg dry wood pr. m
3
compared to beech/oak
Hornbeam 640 110%
Beech and oak 580 100%
Ash 570 98%
Maple 540 93%
Birch 510 88%
Mountain pine 480 83%
Fir 390 67%
Poplar 380 65%
1 kg of wood elds the same heat energy irrespective of wood type. 1 kg beech merely
takes up less space than 1 kg of r.
For the Installer
Finally before ring the stove for the rst time a check should be made to ensure that the
assembly and stove installation has been satisfactory and that there are no leaks in any
seals in the appliance and appliance connections to the chimney.
Ensure that the appliance and chimney ue are functioning correctly before nally hand-
ing over to the user. If necessary read the later parts of this manual for guidance on care
required when rst lighting.
Inform the user that the appliance has been commissioned and ready to use and give
instruction on the safe operation of the stove.
These Instructions must be left with the user and the user should be instructed to keep
them in a safe place.
