If the glass o�en gets dirty, the combus�on temperature
level is low; this indicates the risk of creosote forma�on.
The flue system must be checked at the heater
connec�on and in the chimney's top end. Cold surfaces
tend to create deposits rapidly, that's why it is important
to check the chimney at the top end, as it is
the coldest area, as opposed to the heater connec�on.
The accumulated creosote must be eliminated with a
specific cleaning brush designed for this use.
This is why it is recommended that before each season
of use a professional inspec�on is carried out of all the
system, clean it and repair it, if necessary.
Joints
The joints normally must be changed every 2 or 3 used
seasons, depending on the heater's use. If the sealing of
the door is missing, a new joint ensures an adequate
sealing and improves the heater's opera�ng. Contact
your supplier to provide you with a set of joints for your
heater.
To replace the door joints proceed in the following way:
1.
First take away the old one with a tool or knife �p.
2.

eliminate the cement and fibre residue.
