The first start-up of the insert must be made before
installing the fireplace.
After the first usage of the insert, a check should be
made whether the central heating installation is filled
with water.
If there is a risk of temporary temperature drop below
0°C, the central heating installation should be filled with
anti-freeze liquid.
The use of corrosion inhibitors is recommended.
During the first few hours of burning, the varnish
coating is burned out and, as a consequence, there
might be a specific, often unpleasant smell.
Before the first use, the gaskets (in the upper part
of the chamber) used for protection during transport
must be removed.
