ACUMOTTE
Acumotte is a special chamotte-concrete mixture that we use to lay the combustion chamber in our
fireplace inserts. It is intended primarily to provide better heat accumulation and raise the tempera-
ture inside the fireplace. It also contributes to the better combustion of combustible substances (e.g.
wood gases). This therefore contributes to more efficient, more eco-friendly combustion and keeping
temperature longer.
First firing-up
When preparing the fireplace insert for the first firing-up, we must
remember to thoroughly check that all Acumotte elements are
properly and safely positioned in the combustion chamber. Re-
member that a newly purchased insert is often chilled. The mate-
rials used to build the fireplace must slowly adjust to high tempe-
ratures. Acumotte itself also needs time to adjust to the heat and
achieve an adequate level of drying. Therefore, the first time you
fire-up, keep the furnace temperature relatively low (this can be
achieved by frequent adding small amounts of fuel).
Be careful with Acumotte
Acumotte is a fragile material that is prone to frequent mechani-
cal damage. That is why we have to deal with it properly.
Remember to handle logs very carefully, they should not hit the furnace lining. We will then minimize
the risk of damaging it.
Does cracked Acumotte lose its properties?
Once a slight crack has be noted on the ceramic lining (e.g. the so-called hairline cracks), this is not a
reason for its immediate replacement Acumotte does not lose its properties. It still functions in the
same way and has no negative impact on the combustion process. Remember, however, that the lining
can not be punctured to the steel body (in this case, Acumotte should be replaced).
Acumotte is also consumed
The lining of the combustion chamber, like most consumables, wears out, and after a while we have to
replace it. It is primarily the way of firing in the fireplace that determines how quickly the lining wears.
To keep it in good condition as long as possible:
Use only seasoned wood with a moisture content below 20%.
Delicately insert (not throw!) the logs so as not to damage the ceramic lining,
Add fuel in the grate phase rather than during regular firing. This will enable avoiding high amplitude
of temperatures (it can result in Acumotte damage)
