External air intake - methods of connection.
Ventilation of the combustion chamber can be carried out from the room or from the outside. If the
fireplace stove draws air from the room, it should have an efficient supply/exhaust ventilation system.
Insufficient oxygen supply to the combustion chamber may result in: problems with lighting the co-
oker, excessive smoke on the glass, smoke in the room, ineffective combustion.
The cooker has a built-in air intake from the outside - intake spigot fi 100, 125 mm (depending on the
model). The adjustment of the primary air under the grate is carried out by a single mechanism (re-
gulator) located below the insert door. The cooker is fitted with a triple air system for the combustion
chamber, primary and secondary air.
The distribution of air to the combustion chamber takes place in the space (air chamber) below the
plate - grate on which combustion takes place. Primary air is supplied under the grate located in the
floor of the combustion chamber. Secondary air is supplied through a special duct (located on the rear
wall of the cooker), through a system of holes, to the combustion chamber.
Secondary combustion involves the afterburning of particles in the smoke. The cooker also has an air
curtain system. The air directed through the air control "sweeps" the glass causing the fire and smoke
to move away from the glass, which significantly reduces soot build-up. In this way, oxygen is supplied
to the upper part of the combustion chamber, where the gases produced during wood combustion are
post-combusted, thus reducing the emission of harmful CO into the atmosphere.
On selected models, there is the option of installing an additional damper on the air intake indepen-
dent of the built-in regulator.
