The construction of fire – place having fire – box, glowing steel walls and air transferring from flue intends to give additional convectional heat. This heat transfers to hole through the little square in the entrance of fire – place and to the up – part of portal. Then this heat moves in the limited, isolated layer of heat existing in the fire – place and gets out of the ventilation hole in hot condition in the dome of fire – place and spreads accumulated heat over the room. The fire – place is made ACCORDING TO THE EUROPEAN STANDARD UNE-EN 13229:2001.

Operation Principles of convectional fire – place

The convectional fire – place consists of three main integral parts: closed cassette fuse (heat exchange or without it), cover and flue.

How does convectional fire – place operate?
The simple operation principles are: the cold air of room enters to the void of fire cinder, then heats taking the warmth in the surface of fuse itself and rises up. Hot air reaching to the injection place under the ceiling returns back room between decorative bars. Modern systems enable controlling of burning intensity and movement of air. The air is used through the street or subsidiary, non – residential rooms, in such systems, In its turn, this prevents combustion of oxygen in the air and water. Automatic cover system, obligatory transference of air as well as counter-flow system are used for this. In its turn, counter-flow system implies obligatory transference of air from up –part, through the ventilation cage and passes it to the bottom. This enables, avoiding from “cold floor” effect. West producers worked out additional heat exchange elements for convectional fuse with the purpose to increase heating efficiency of fuses and fire – places: faience elements for accumulation of warmth, is used water elements in air heating system in order to meet agricultural needs.

The advantages of convectional fire – place:
– clear vision of flame
– great combustion power
– opportunity of heating of neighbor rooms
– rapid heating during short period
– regulated heat emission
– width of construction and design capacity

During joining ready fire – place, the installation and connection of fuse is implemented at the same time with the installation of fire place.
The use of cast – iron fuse is prohibited as separate heating device ( outside from mask and cover of fire – place ).
Regardless type of mask, the implementation of following terms are important during installation of fuse.

  • it is installation on the cast – iron fuse base or concrete tiles
  • it is important to use distances indicated below:

1. 20 mm – between fuse and wall connection
2. 60 mm – convectional intermediate between fuse and heater covered by foil sheet
3. There should be at least 5 mm from left to right between fuse and mask.
Contact of fuse and mask with each other is not allowed ;
4. The mask location of fuse should provide cleaning of its entire external surface by being blown with air independently.

  • The vertical axis of flue draw nearer maximum to the vertical axis of fuse.
  • Joining locations with side tube and fuse of connecting pipe are fixed refractory materials and heat resistant mastic.
