on the product may release some smoke or smell.
Both the smoke and smell will disappear and are not
hazardous.
Lighting a fire
Insert small dry pieces of kindling wood, ignite and
ensure that the flames have established on the wood
before closing the door. Open the air vent control (FIG
A) before you close the door. Additional ignition air is
obtained by keeping the door slightly open. When the
flames are stable and the chimney is warm, the air
supply is regulated with the air vent control.
When there is a glowing layer of ash, new wood logs
can be inserted. Pull the hot ember to the front of
the combustion chamber when inserting new logs so
that the wood is ignited from the front. Keep the door
slightly open each time new logs are inserted so that
the flames get established. The fire should burn with
bright and lively flames.
Using the insert with low combustion effect and firing
around the clock increase pollution as well as the
risk for a fire in the chimney. Never allow the insert
or flue to become glowing red. Turn off the air vent
control should this happen. Regulation of the air vent
control takes some experience, but after a little while
a natural rhythm for the fire will be found.
IMPORTANT! Always remember to open the air
vent control (preferably also the door) before
new wood logs are inserted into a hot burn
chamber. Let the flames get a good grip on the
wood before the air control setting is reduced.
When the draught in the chimney is low and the
vent is closed, the gas from the firewood can be
ignited with a bang. This can cause damages
to the product as well as the immediate
environment.

6. Maintenance

Cleaning and inspection
The insert should be inspected thoroughly and
cleaned at least once per season (possibly in
combination with the sweeping of the chimney and
chimney pipes). Ensure that all joints are tight and
that the gaskets are rightly positioned. Exchange any
gaskets that are worn or deformed.
Remember that the insert must always be cold when
inspected.
Ashes
The ashes should be removed at regular intervals.
Be aware that the ashes can contain hot ember even
several days after the fire is finished. Use a container
of non-combustible material to remove the ashes. It is
recommended to leave a layer of ashes in the bottom
as this further insulates the burn chamber. Take
12 12
care with the Thermotte plates when the ashes are
removed, particularly when using an ash shovel, so as
not to damage them.
Thermotte™ insulating plates
The insulating plates in the burn chamber (FIG 10)
contribute to a high combustion temperature, which
leads to cleaner combustion of the wood and a higher
rate of efficiency. Any fissures in the plates will not
reduce their insulation efficiency.
If new plates are needed, contact your dealer.

6. Bottom plate
Please note: Wood logs that are too long can cause
strain and crack the plates, due to the tension created
between the side plates.
Please also note that the Thermotte plates may
release coloured dust when touched. Avoid touching
any cast iron parts with dust on your fingers. Any
visible dust on cast iron can be brushed off with the
glove that is included.
Door and glass
Should there be any soot on the glass it may be
necessary to clean it. Use dedicated glass cleaner,
as other detergents may damage the glass. (NB! Be
careful, even dedicated glass cleaner can damage
the varnish on the door frame and gaskets). A good
advice for cleaning the glass is to use a damp cloth or
kitchen roll paper and apply some ash from the burn
chamber. Rub around the ash on the glass and finish
off with a piece of clean and damp kitchen roll paper.
NB! Only clean when the glass is cold.
Check regularly that the transition between the glass
and the door is completely tight. Possibly tighten the
screws that hold the glass in place - but not too hard,
as this can cause the glass to crack.
Periodically, it may be necessary to change the
gaskets on the door to ensure that the burn chamber
is air tight and working optimally. These gaskets can
be bought as a set, usually including ceramic glue.
