from the outside. This system enables the supply of cold air for the combustion process. In addition,
the air supply should be equipped with a throttle so that the room does not lose heat while the fire-
place is not in use. There are two ways to distribute the hot air in the room: gravitation and forced.
GRAVITATION HOT AIR DISTRIBUTION SYSTEM
When we heat an area of not more than the room where the fireplace is and adjacent rooms, choose
the gravity system. In this case, hot air will move upwardly into the chamber by way of the heating
pipes, the so-called thermal buoyancy. If you implement this system, remember to properly insulate
and keep the distribution pipes reasonably short (up to 3 meters). At the same time, hot air can not
be distributed to too many rooms. If the distance is more than 3 meters from the flue, hot air is not
able to overcome resistance and it does not reach the outlets or its speed is too low, with the result
that gravity flow is not sufficient.
The advantage of this system are relatively small financial costs to be incurred for installation.
A high-temperature defect that, in the absence of proper filtration, can cause a very the unfavourable
phenomenon of the pyrolysis of dust, and therefore the system is less frequently used and not
recommended.
FORCED HOT AIR DISTRIBUTION SYSTEM
The system requires the installation of a supply device - a turbine that sucks hot air heated by the
fireplace insert and pumps it to all branches of the system. Therefore, in this case, a flue pipe that
connects the insert with the air-supply device is used with the maximum possible cross-section and
the minimum length.
The DGP installation requires:
• ducts, pipes, passages, reducers, distribution boxes, filters, all usually made of galvanized steel;
• fireplace grates or anemostats;
• insulated flexible ducts characterized by the minimal resistance up to 250 ° C (fully non-flammable);
• supply device, e.g. a turbine.
All of the above elements can be found in our offer.
The DGP system installation should be entrusted to a specialized company that will design a proper
system of connections and the distribution of individual elements. Prior to installation of the insert
and the DGP system, check the heat demand for the location you want to warm up and the required
equipment for this purpose.
Forced systems undoubtedly offer more opportunities than gravity systems.
On the other hand, the disadvantage is the more complicated assembly system and the costs related
to the operation, i.e. the current consumption of the turbine. These expenses, however, are compen-
sated by savings that can be felt in the bill for heating the building.
The following figure shows a diagram of an exemplary installation and connection to the chimney.

MAINTENANCE OF THE FIREPLACE INSERT
Maintenance activities of the fireplace insert and smoke ducts consist of ensuring compliance with
the following guidelines.
Periodic or ordered maintenance of the insert include:
• ash removal, cleaning the glass, cleaning the combustion chamber, cleaning the flue duct;
• leaving ash in the ash drawer for an extended period will cause chemical ash panning;
• periodic cleaning the combustion chamber of the insert (the frequency of this operation depends on
the species of wood used and the moisture content);
