4. FUEL TYPE SELECTION
Ÿ
You can use all kinds of natural, chemically non-treated wood and pieces of
wood bark. You can also use charcoal or coal briquettes.
Ÿ
The use of dry beech wood with moisture content not exceeding 25% is
recommended.
Ÿ
If the moisture content in the wood is high, water evaporation can lead to
condensation and damage the oven.
Ÿ
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).
Ÿ
Combustion of the above materials besides releasing a very bad smell also
generates harmful emissions that are harmful to health and damage the
environment.
5.1. PRIMARY AIR
Ÿ
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.
5.2. SECONDARY AIR
Ÿ
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.
Ÿ
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
Ÿ
During the stove operation the secondary air regulation lever should never be
completely closed.

REGULATION OF COMBUSTION AIR
Ÿ
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.
Ÿ
When starting the fire both primary and secondary air should be fully open (pull
the lever towards you until the end).
Ÿ
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.
Ÿ
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.
