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 insert to the chimney is displayed in Figure 1.

To ensure a failure-free operation, the chimney blast must be kept at 10 Pa (measured inside of smoke tube behind the fireplace insert).
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 insert 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 insert operation requires sufficient space venting, meaning incoming flow of outside air into the space where the fireplace
insert 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 insert a special opening is made in the external wall, in the area where fireplace insert 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 insert needs for wood combustion up to 20 m
3
of fresh air per hour.
Insufficient air flow runs counter to proper operation of fireplace inserts and is a threat to your safety!
Let the installation of your fireplace insert, 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 insert with appropriate flue at safe distance which is at minimum 400 mm from these objects.
Safe distance should be doubled if the fireplace insert 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 insert on nonflammable, heat-insulating pad with dimensions exceeding
the contour of fireplace insert 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 insert,
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.
Safe distance between the outer skin of fireplace insert (on sides and behind) and the internal wall of backing must be at least 10 cm.
Minimum dimensions of air intake of interior air are 20x20 cm.
Minimum dimensions of exhaust outlet of heated air are double the size of air intake.
The fireplace insert lining must be of fireproof material.
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 (e.g. bonding
of floor coverings), the fireplace insert must be shut off before the danger arises.
The fireplace insert 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 insert in operation.
No flammable liquids can be used to heat up.
IT IS FORBIDDEN TO INCREASE THE NOMINAL THERMAL POWER OF THE FIREPLACE INSERT USING FLAMMABLE LIQUIDS.
The fireplace insert cannot 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 in
open air.
