4. FUEL TYPE SELECTION

You can use all kinds of natural, chemically non-treated wood and pieces of

wood bark. You can also use charcoal or coal briquettes.

The use of dry beech wood with moisture content not exceeding 25% is

recommended.

If the moisture content in the wood is high, water evaporation can lead to

condensation and damage the oven.

It is prohibited to use a lacquered wood, laminated wood or plastic-coated wood,

wood treated with protective agents, household waste, paper briquettes,

ﬂammable liquids (including methanol and ethanol).

Combustion of the above materials besides releasing a very bad smell also

generates harmful emissions that are harmful to health and damage the

environment.

Primary air is brought into the lower part of the stove under the grate in the

combustion chamber and provides a quick raise of stove temperature during the

ignition phase.

Secondary air is brought into the upper zone of stove and supplies the

combustion chamber with a certain amount of hot air required for complete

combustion of gases that are released during the wood burning. Secondary air

has another role and that is to prevent the forming of soot layers on the stove

door glass.

For controlling the secondary air there is a general rule and that is: small ﬁre

requires a small amount of secondary air and a big ﬁre requires more secondary

air

During the stove operation the secondary air regulation lever should never be

completely closed.

Solid fuel stoves ABC ROLO and ABC Quadro are equipped with a unique

system for controlling the ﬂow of combustion air so that at all times, by simple

control of the primary and secondary air, you get maximum efﬁciency rate and

minimum fuel consumption.

When starting the ﬁre both primary and secondary air should be fully open (pull

the lever towards you until the end).

Fuel is added only when the previous amount of the fuel is burnt. Enough

quantity is 2 - 3 wood pieces with total weight of 1.5-2kg and we recommend that

the pieces of wood are arranged in a single layer if possible.

If you use a charcoal, it is enough to add 2-3 small lumps in the middle of the

combustion chamber, open primary air to the maximum and adjust the

secondary air as needed.
