1. Introduction.

The fireplaces (appliances) are designed and tested in accordance with the requirements of European
standard EN 13240:2001 and the fireboxes (appliances) according to the European standard EN 13229:2001 and
conform to the approved technical documentation. They are designed for intermittent burning and operate with
fire doors closed.

Please, do not leave this instruction unread. The assembly and the exploitation of an appliance are
connected with different legal obligations, which are explained in this instruction. According to the laws and
regulations for safety, when using an appliance of such class, the buyer and the user are obliged, with the help
of this instruction, to inform themselves for the assembling and the right operation of the appliance.

2. Appliance assembling.

2.1. Fireplace.

The technical parameters of the fireplace are given in Appendix 1.

Schematic diagrams for connecting a fireplace with an integral boiler to heating systems are given in
Appendix 2.

It is necessary the following conditions to be kept in order to ensure a safe and correct work of the fireplace:

The fireplace should be installed in rooms with sufficient air flow which is required for the combustion.

Not every fireplace could be connected to any chimney. Before assembling the fireplace check if the static
pressure and the chimney dimensions conform to the required parameters for the fireplace. If the fireplace does
not conform to the chimney, it will lead to a lower burning rate and polluting the glass with soot.

The chimney should be high enough (not less than 5 meters). Only one more appliance is allowed to be
connected to the same chimney. The flue draught should be higher than 10 Pa, and for fireplaces with a boiler
higher than 15 Pa. If the chimney is too high (the draught exceeding 35 Pa) then it is necessary to mount a
supplementary valve to diminish the draught.

The fireplace should not be connected to a chimney when there is another boiler connected to it.

The floor where the fireplace is placed should be flat and horizontal, made of non-combustible materials
(mosaic, marble, terracotta, etc.). If the floor is not heat resistant (carpets, linoleums or others of the same kind) a
stable, non-combustible plate should be used, made of steel, glass or stone plates. If a heat resistant plate is used,
it should come out: 50 cm in front and 30 cm from both sides, measured from the fire door of the fireplace.

If there are any combustible materials or constructions, the fireplace should be away from them at 80 cm, or
an additional incombustible screen should be placed. The distances to which a fireplace should be installed, in
order to escape fire hazards, are given in Appendix 1.

After placing the fireplace it is connected to the chimney by chimney pipes. The joints between the chimney
pipes and the socket should be tight. The chimney pipe should not enter into the chimney.

2.2. Firebox.

Please, observe all the requirements shown in point 2.1. In addition, it is necessary to observe the following
conditions:

It is recommended that the mounting of the fireboxes to be done by special organizations.

When mounting the firebox into surrounding, heat resistant and inflammable materials should be used only.

The firebox can be installed in a special made niche or in a surround.

The floor, where the firebox will be placed, should be smooth and leveled, made of inflammable materials,
possessing the required load capacity, otherwise additional suitable measures should be taken, as building a
supportive concrete plate or reinforced putty. The fire chamber should be fixed steadily to its base. Fireboxes
from the type “Diplomat” and “Uyut”, after being placed should be leveled by means of four bolts M12x50
situated on the bottom of the firebox, the access to them will be through the ash pan. Any eventual inaccuracy
when building the niche could be compensated by the stripes, mounted on the side of the firebox by means of
bolts M6x10.

If the floor in front of the firebox is made of combustible materials it is necessary to dispose inflammable
plate (steel, ceramic, glass etc.) which can comprise the space of 50 cm in front of the fire door and 30 cm of both
sides.

If there are any easy combustible materials or constructions, the firebox should be away from them at 80 cm,
or an additional incombustible screen should be placed.

It is necessary to ensure enough distance between the firebox and the niche (surround), as well as enabling
the natural air flow for blowing the walls and the floor.

Close to the walls of the niche (surround) isolation is mounted, which protects it from heat and heat loss. The
isolation must be specially made for appliances of such type, and should endure up to 700°C-1200°C (usually it is a

4

sheet and obligatory foiled). The foil serves as a deflector of the beam heat and reduces the heat loss. Despite
wadding round the fire chamber it is compulsory to enable 5 cm air flow for heat exchange and cooling.

By means of suitable decorative ventilation grilles ensure the flow of cold air in the bottom of the firebox and

outflow of hot air in the upper part of the decorative lining.

For proving the heat exchange and efficiency of the heating system it is admitted to build in the air system a

suitable electric fan, otherwise you can only count on the natural convection.

If your firebox is supplied with an integral boiler, additional elements (as pump, valves, etc) can be mounted,
so that they can be visible and easy for access. You should foresee openings (lids) for servicing of the internal
space and the connections.

The firebox should be mounted in rooms, where there is sufficient air flow, required for burning.

3. Appliance operation.

3.1. Fuels.

The most appropriate fuels are dry cleaved wood (wood logs) and briquettes. The wood logs, stored in the
open under sheds, reach a humidity level of 10%-15% after 2 years, when they are most suitable for combustion.
We recommend to burn wood dried as much as possible. The maximum heat output is reached after burning
wood logs dried for at least 2 years period of time.

The newly cut wood has little calorific value, high humidity and burns poorly –they extract a lot of flue gases
and additionally contaminate the environment. This leads to minimizing the longevity of the appliance and
chimney as well. The increased condensate and tar content in the flue gases leads to blocking up the flue pipes
and the chimney, and an appreciable impurity of the glass. When using them, the heat output of the appliance
falls to 50%, and the fuel consumption grows twice. The type and the recommended quantity of fuel for the
appliance are given in Appendix 1.

It is not recommended to use the following fuels in the appliance: wet or tarred wood, shavings, fine coal,
paper and cardboard (except for the ignition), polymeric materials.

Do not use liquid fuels.

Do not use the appliance like a furnace for burning waste matters.

If the appliance is used for burning unalloyed fuels then the warranty is not valid.

3.2. Components.

Glass

The mounted glass is ceramic, and it stands up to 850°C so it cannot be damaged by the temperature which

is achieved when the appliance is operating. But it could be damaged by a mechanical influence when installing or
transporting the appliance, or by putting big wooden logs into the firebox.

The glass belongs to the spare parts which are quickly worn out, and that is why it is not included in the
warranty conditions.

Polluting the glass with soot

The construction of the appliance helps during exploitation not to pollute the glass with soot. The soot is
accumulated only when there is bad burning, which may be caused by some reasons: the static pressure and the
dimension of the chimney do not conform to the required parameters of the appliance, the air flow necessary for
combustion process is stopped too early, or the right fuel is not used. In order to keep the glass as clean as
possible from soot, the wood logs must be placed in such a manner that the cut surface is not facing to the glass.

We cannot influence those factors and that’s the reason why we cannot guarantee that the glass won’t be
polluted with soot.

Refractory plates /fireclay, vermiculite/

The firebox is supplied with refractory plates. These plates keep the heat and give it back into the firebox in
order to increase the burning temperature. The higher is the burning temperature, the higher is the efficiency of
the burning process. As a result of too high temperatures or mechanical influences the refractory plates might be
damaged. Extremely high temperatures may be achieved when with high flue draught of the chimney, the
primary and secondary air controls are open, and thus it makes a burning out of control. Under mechanical
influence it is understood e.g. throwing a wood log into the firebox or using bigger wood logs.

The refractory plates might be easily exchanged. If there is only a crack then it is not necessary to change
them. It is necessary only in case when the metal parts between them or under them can be visibly seen.

The refractory plates are quickly worn out, and that is why they are not included in the warranty
conditions.

Sealing

The sealing of the appliance are made of special glass fiber and does not content asbestos. This material is
worn out during usage and the sealing must be periodically exchanged. Your shopkeeper could order these
sealing to us.

The sealing is quickly worn out part and that is why it is not included in the warranty conditions.
