Warning
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.
