handling. We recommend you to read the instructions carefully in order to avoid any risk
related to likely damage. Proper operation and maintenance affects the service life of the
product as well. In addition, proper operation and fuel supply is connected with fuel savings
and environment protection. Technical specifications are included in the manual.
The manufacturer provides guarantee providing you adhere to the directions and
recommendations in the instructions for operation and maintenance. Keep the operating
instructions and technical card safe to be able to refresh your knowledge at the beginning
of the new heating season.
1. TECHNICAL SPECIFICATIONS
The combined fireplace stove with the warm water exchanger is designed for heating in
habitable rooms, recreational buildings, work stations and other places to provide thermal
comfort, while the visual effect – the perception connected with flame – is similar to the
sensation of live fire. The warm water distribution system may be open or closed, made
with an auxiliary circulating pump or without the pump. The warm water distribution system
may be completed with e.g. service water heater. A good solution may be an integration of
the fireplace stove to the already built heating system with a gas boiler (electric boiler, or
other heating systems). In order to provide safety operation of the fireplace stove and
automatic back-up for the function of the circulating pump in case of electric power failure, it
is recommended to use a back-up power supply (See Supplement 3).
1.1. Heating concept
The fireplace stove is designed for burning wood, eco-fuel cakes and coal cakes (specific
types only) in a burning-through way, characteristic with very good firing conditions.
By means of the warm water exchanger, the fireplace stove hands some 50% of the heat
output in the central heating circuit or floor heating. The rest of the available heat is used
for heating of the air in the room where the fireplace stove is installed.
The air within the room is heated thus the thermal comfort is provided by heat convection,
in part by heat radiation as well. This way, you can heat up even very cold, long-time
unheated rooms very quickly. The concept of heating by means of heat convection is based
on the fact that the air in the room enters the fireplace stove at its bottom part, being heated
in the course of its way up inside the convection space consisting of a double shell of the
heating device. The air then flows through the holes in the upper part of the fireplace stove
back in the room. The radiation heat is generated by means of surface areas of the
fireplace stove (metal, ceramics, glass). Due to the construction, the biggest radiation heat
source is the glass door.
1.2. Construction design
The fireplace stove is welded of steel profiles, thickness 2-5 mm. In the middle of the
fireplace stove, there is a firing chamber that may be closed with a stocking door (equipped
with a self-acting element). The door is provided with special a large-area glass sheet,
thermal resistance up to 800 °C.
The inner space of the firing chamber is usually lined with fireclay brick shapes. The bricks
are not jointed with any filler (the reason is a protection of the bricks against damage by
thermic dilatation). The upper part of the firing chamber is equipped with partitions
designed for directing flue gases into a smoke outlet. The partitions may be fixed or
movable. Such movable partition may serve as a supporting holder for fireclay bricks. At
the bottom part of the firing chamber, a simple, fixed cast grate is installed. Before the
