1. Installation manual
1.1 General
Fireplace insert for wood (further only “fireplace”) is a single-shaft heating device which replaces the existing heating for short
periods between seasons or supports it in the cold seasons. Fireplace is designed for local heating.
This fireplace has been tested according the standard EN 13229 with fuels: wood and brown-coal briquettes. This fireplace met
the requirements of this standard.
All local regulations, including regulations relating to national and European standards have to be followed when installing the
fireplace. Before mounting the fireplace, you have to inform the competent master chimney sweep who will inspect as expert the
proper connection of fireplace to the chimney.
Fireplace must be installed on floorings that have corresponding loading capacity. By installation, it is necessary to ensure
sufficient space for cleaning of fireplace, flue and chimney.
The fireplace must be closed during operation, but also when not in operation, because otherwise it might significantly affect other
devices connected to the chimney.
Combustion chamber is enclosed by sheet metal plate filled from inside with fire- bricks. In the bottom part of the combustion
chamber, there is the bed with cast-iron grate. There is an ash box under the grate. Stokers door are sealed with gasket. The door
may be opened only to add fuel. The stokers door are paned with highly heat-resistant glass-ceramic.
The smallest size of the front opening in the lining of fireplace is: width 510 mm and height 525 mm for DOMINO II, width and
height 600 mm for DOMINO III. Surface temperatures of the lining can reach, depending on thermal resistance coefficient of the
used construction material and its thickness, within the range between 30 and 80°C.
NOTE: when claiming or ordering spare parts always quote the name, type and serial number given on the data card.

The fireplace can be used to connect a multi-occupied chimney, which means that to the chimney with the fireplace connected, we
can connect more devices.
Before connecting the fireplace, make sure there is sufficient blast in the chimney. Flame of a burning paper or candle should be
sucked into the chimney opening. The fireplace should be attached to the chimney flue in the shortest direction.
The fireplace should be attached to the chimney flue always with the consent of competent chimney sweeper office in compliance
with STN 73 4210 and STN 73 4201.
If the fireplace cannot be attached to the chimney flue directly, the flue involved should be the shortest possible and ascend
towards the chimney. Flues can be of maximum 1,5 m length. In any case, it is necessary to ensure smoke tubes and bends,
mounted on exhaust throat, against getting loose by a pin. Smoke tubes and bends must be attached firm and tight to the fireplace
and plugged into each other by minimum 40 mm length in the direction of chimney blast. The chimney opening must be fitted with
a sheet metal case with a diameter corresponding to the diameter of used smoke tubes.
Correct and incorrect connection of fireplace to the chimney is displayed in Figure 1.

To ensure a failure-free operation, the chimney blast must be kept at 12 Pa (measured inside of smoke tube behind the fireplace).
As the chimney blast can be affected by changeable factors, as the outside air temperature, combustion temperature, chimney
lining, wind power, etc., it varies during the year. Therefore it is recommended to install a damper inside of the chimney.
The fireplace can reach the specified performance and efficiency as long as it is connected to a chimney with sufficient blast
draught. The chimney´s cross section must be 150x150 mm, and minimum height 5 meters.
1.4 Space venting
The fireplace operation requires sufficient space venting, meaning incoming flow of outside air into the space where the fireplace is
operated. That can be done through an open window or open external door. However, it is safer, if together with the installation of
fireplace a special opening is made in the external wall, in the area where fireplace is mounted, in order to ensure sufficient
incoming air flow for combustion. Adjustable ventilation grille, opened and closed from inside, should be embedded in the opening.
The fireplace needs for wood combustion up to 20 m3 of fresh air per hour.
Insufficient air flow runs counter to proper operation of fireplace and is a threat to your safety!
Let the installation of your fireplace, its connection to chimney and venting be tested by a competent chimney sweep in
your area!
1.5 Fire safety
It is obligatory to strictly adhere to the rules of fire safety covered by STN 92 0300.
In case of nearby flammable building material or objects with combustibility degree B, C1 and C2 according to STN 73 0823, place
the fireplace with appropriate flue at safe distance which is at minimum 400 mm from these objects.
Safe distance should be doubled if the fireplace with flue was standing close to material with the combustibility degree C3. The
same applies if the degree of combustibility for the material cannot be proved.
Safe distance can be decreased to half in case of using a nonflammable, heat-insulating shading board, min. 5 mm thick, placed in
such a way there is 25 mm gap left between the board and the protected flammable object.
If the flooring is made of flammable material, place the fireplace on nonflammable, heat-insulating pad with dimensions exceeding
the contour of fireplace by 300 mm in the front and by 100 mm on all other sides. The smallest dimensions of the pad and the
location method are displayed in Figure 2. Shading board placed on the protected object must exceed the contour of fireplace,
including the smoke tubes, by at least 150 mm on each side and at least 300 mm above the upper area.
In case of fire in chimney follow the fire safety rules.

2. Operation manual
2.1 Important safety instructions
In case of conditions leading to danger of temporarily present flammable gases or when there is a danger of fire or explosion
present at some kind of work (e.g. bonding of floor coverings), the fireplace must be shut off before the danger arises.
The fireplace must be operated according to this manual. It can be only operated by adult persons; it is unacceptable to leave
children close to the fireplace in operation.
No flammable liquids can be used to heat up.
IT IS FORBIDDEN TO INCREASE THE NOMINAL THERMAL POWER OF THE FIREPLACE USING FLAMMABLE LIQUIDS.
The fireplace must not be operated with stoker door open.
Ash has to be disposed of carefully, and placed in nonflammable containers with cover; hot ash cannot be placed in ash bins or
kept it open air.
Damaged or nonoperational fireplace must not be used. The user must provide its professional repair before using it again.
Ash accumulation in smoke tubes and bends must be checked at least once a month and cleaning provided when required.
During operation, all air supplies to fireplace must not be closed.
During operation, it is necessary to monitor the functions of the fireplace and the fire safety. You must check the amount of fuel in
the hearth, sooting of the grate, conditions of control mechanisms of combustion air, if the door is closed and if the surrounding is
clean.
Broken fire brick in hearth is no obstacle to further use of fireplace. This does not apply to ceiling vermiculite.
When used simultaneously with other heating device, proper area venting must be provided (see part 1.4).
2.2 Fuel
This fireplace is intended for use of: wood, brown-coal briquettes 7”, 6” long.
Emission standard dictates that only naturally dried wood (humidity content max. 20%) can be used. Wet wood causes strong tar
condensation. The most suitable are wooden logs with diameter of 30 cm and 30 cm long, stored in dry place for at least 2 years.
Most suitable are: beech, oak, hornbeam, birch and fruit trees wood.
Unsuitable or unacceptable fuel: Only fuel mentioned above can be used.
Unacceptable for use is also: carbon grit, finely chopped chips, bark and chipboard waste, wet wood and wood treated by a
prophylactic, paper and pasteboard (except heating up).
Waste combustion is forbidden by Law of protection against emissions.
Combustion gases produced by waste combustion can threaten your health and cause damage to fire bricks and metal parts of
your fireplace and to your chimney.
2.3 Fireplace setting
The fireplace has control sliders for supply and control of combustion air flow:
- Primary air: one control slider on stoker door at the bottom.
- Secondary air: one control slider on stoker door at the upper side.
Control sliders are marked with signs: “0” – closed, “I” – open.
NOTE: the control mechanisms can be very hot! Use the glove supplied as an accessory for manipulation of hot objects.
2.4 Heating up
Before heating up you must open all air suppliers (control valves to “I”). At the same time, ensure air supply to the room (see part
1.4). Recommended fuel should be supplied at the nominal thermal power in intervals of one hour.
Fire is set up using paper and thin wooden chips. Never use petrol, alcohol, kerosene, etc. Place a layer of wooden logs and
briquettes on the fire.
Never use more than three wooden logs as fuel load.
When using the fireplace for the first time, heat it up with a small fire. First, wait until the fire becomes bigger so that the fireplace
could slowly and evenly extend and the fireplace body will not suffer any damage due to temperature tension.
To achieve this, you have to set the control valves for both primary and secondary air immediately (once the fire is burning well) to
medium setting.
In case of difficulties with heating up (weather changes, cold chimney, etc.), local fire is set up in the fireplace using paper to heat it
up better. During heating up it is necessary to check on the combustion and constantly monitor the fireplace.
The fireplace is covered with heatproof paint that hardens at higher temperatures. Therefore smell is produced during the first
phase of heating up. For this reason, especially at the first use, sufficient venting must be provided.
We do not recommend touching the external paint of the fireplace when using for the first time, because it is not yet hardened and
it could be damaged.
