Convection area
- If the hot-air jacket is not used, then between the fireplace insert and the insulation layer (4, 15)
there must be a minimum gap of 6 cm on the rear and side areas.
- The convection area must be insulated from all walls with the exception of walls which form the
heat-exchange area of the surroundings.
- The walls, floor and ceiling of the convection area must be clean and resistant to the abrasion.
flow of convection air from the hot-air jacket
- All hot convectional piping must consist of form stable non-flammable materials.
- When installing a hot-air jacket, the hose for the flow of hot air must be firmly connected
to the flange of the hot-air jacket and to the input grid.
operation of the air grid (hypocaust)
- The conventional air circulates in the closed shelling. The heat from the convectional area is
transferred into the room through the heat-exchange areas of the surroundings.
- The heat load in the convectional area of the hypocaust is higher than that for the construction
with air grids. This higher heat load must be taken into account for additional insulation of the
conventional space.
- The size and the construction of the heat-exchange area of the surroundings must correspond
to the heat output of the insert.
forewall (protection of walls from flammable materials)
- This is used to protect the walls of the building (20) and consists of mineral material with a
minimum thickness of 10 cm.
- The pre-wall may be terminated a minimum of 20 cm above the chimney flue (3).
- The forewall is not required to be built when the wall of the building:
- is at least 10 cm thick
- is constructed from non-flammable materials
- is not a load-bearing concrete wall or a reinforced concrete wall
