1. Introduction
Thank you for for purchasing our fireplace stove and congratulations for becoming the owners of top-notch
fireplace stoves by Jydepejsen.
Our fireplace stoves can function as additional heating to augment the atmosphere of your home or recreational
building or as the main source of environmentally-friendly heating with high heat output, dust-free operation and
perfect combustion. All fireplace heaters produced by our company are tested in accordance with current
legislation.
Please read through the manual and technical sheet thoroughly. The user is obliged to get properly acquainted
with proper installation and operation of this device with regards to its safe operation. Please keep the manual
and technical sheet so that you can brush up all the information necessary for the correct operation of your
fireplace stove before each heating season.
We only provide a warranty on our products if all the instructions listed in this operation manual are adhered to.
2. Technical description
Fireplace stoves are intended for installation into various interiors. Jydepejsen fireplace stoves are manufactured
from quality construction materials — cast metal, CORTEN steel and quality construction and fittings steel, with
stressed parts made of HARDOX steel. The surface of steel constructions is protected by a refractory opaque
paint. Refractory paints are not anti-corrosive. The combustion chamber of full-plate fireplace stoves is padded
by removable vermiculite desks, which are not connected by any paste material to prevent damage by heat
dilatation. The combustion chamber can be firmly closed by doors with special heat-resistant glass. The glass not
only increases the aesthetics of the flickering flames, but also facilitates pleasant heat radiation. The glass also
prevents the sparks from the burning wood and smoke from entering the room. The floor of the combustion
chamber is usually equipped with a removable cast-iron grate. Usually, a barrier, or alternatively a sheet metal
or ceramic mould, is placed in front of the grate to prevent the fuel falling and sliding onto the doors (front
window). Grate fireplaces include room for an ashpan under the grate. Some types allow custom-configuration
of the flue pipe throat for top- or back-side exhaustion. The fireplace stoves are manufactured with dual coating.
The area between the coatings is used for air heating. The upper part of the outer coating includes vents for the
heated air. The outer coating may include ceramics or stone to highlight the design and improve the heat
accumulation properties of the fireplace stove. Some types of fireplace stoves have adapted the double-coating
construction to heat warm service water with an optional connection to the standard heating system. These
fireplace stoves may be equipped with a cooling loop to avoid overheating in case of power outages.
Fireplace stoves equipped with a separate intake of primary and secondary combustion air include the
appropriate control elements. The primary air is taken to the burning fuel (usually through the ashpan and grate)
and is used for primary combustion. The secondary air supports combustion of residual combustible gases in the
exhaust, increasing the output of the heater and significantly reduces the amount of pollutants escaping into the
atmosphere. The secondary air is mostly taken to the area above the burning fuel. Its presence causes the cold
air to roll around the inner side of the front glass. This process simultaneously prevents the blackening of the
front glass. The secondary air also participates in the primary combustion process when the primary air intake is
partially or completely sealed. Keep the primary air intake fully open at the beginning of the combustion
process, when the chimney draft is still weak. After the chimney heats up, you can partially or even completely
close the primary air intake, based on the target output of the fireplace stove. It is also possible to reduce the
fueling or limit the chimney draft by attaching a smoke shutter (a manual shutter in the flue pipe limiting the air
intake to at most 75%) to reduce the output of the fireplace stove. This is recommended especially for chimney
draft around and above 20Pa. The secondary damper is intended to fully close the stove when it is not in
operation. The fireplace and ashpan covers must always be closed except for starting operation, adding fuel and
removing solid combustion remnants to prevent exhausts entering the room.
Some fireplace stoves are equipped with a heat accumulation exchanger, improving the efficiency of the fireplace
stoves and maximally utilizing the fuel energy.
Some fireplace stoves are manufactured with a central air intake (CAI). This allows air to flow into the
combustion chamber in the fireplace stove from the exterior, halls, technical rooms etc. Fireplace stoves with a
CAI are not dependant on the amount of air in the heated area. Thus, they not only contribute to a pleasant
atmosphere in your home, but also reduce energy expenses (since heated air already in the room is not
consumed).
