Attention!
We do not recommend using fuel briquettes/
compact wood in our products. Use of such fuel
may cause the product to overheat and exceed the
temperatures determined safe.
Burning briquettes/ compact wood is done so at
your own risk and only small amounts (max 1/3 of
normal load) should be used for each load.
NEVER use impregnated wood, painted wood,
plywood, chipboard, rubbish, milk cartons,
printed material or similar. If any of these items
are used as fuel the warranty is invalid.
Common to these materials is that they during
combustion can form hydrochloric acid and
heavy metals that are harmful to the environment,
you and the insert. Hydrochloric acid can also
corrode the steel in the chimney or masonry in
a masonry chimney. Also, avoid firing with bark,
sawdust or other extremely fine wood, apart from
when lighting a fire. This form of fuel can easily
cause a flashover that can lead to temperatures
that are too high.
Warning Make sure the insert is not overheated
- it can cause irreparable damage to the product.
Such damage is not covered by the warranty.
