1.7 HEATING CAPACITY
Check the heating capacity of the appliance by comparing the rated power given in the paragraph "TECHNICAL DATA" with the power
required by the environment to be heated.
The energy requirement may be calculated approximately by multiplying the square metres of area by the height of the ceiling; the result is
then multiplied by a coefficient, which depends on the degree of insulation of the building, that is, on internal and external factors of the
dwelling:
Internal factors: type of window and door frames, thickness of the insulation and walls, type of building materials, presence of stairwells,
walls with extensive glazing, high ceilings, position of the rooms to be heated in relation to other adjacent heated or unheated rooms,
External factors: geographical position, average outdoor temperature, exposure, wind speed, latitude, altitude, …
Example of approximate calculation of the energy requirement to heat a fixed volume to 18/20° C:
The coefficient that is normally used is determined according to the real conditions as they occur case by case.
From 0.04 to 0.05 kW per cubic metre in a well insulated environment
From 0.05 to 0.06 kW per cubic metre in a poorly insulated environment
3 rooms measuring 20m 2 X (H ceiling) 2.7m = 162 m 3 (volume)
In an environment with a good degree of insulation, an average value (coefficient) of 0.045 kW may be taken
162 (volume) X 0.045 (kW) = 7.3 kW necessary (6300 kcal/h)
Conversion 1kW = 860 kcal/h
Consult a heating technician or engineer for a correct check and calculation of the requirement of the environments to be heated (see
"REFERENCE STANDARDS").
1.8 SUITABLE HEAT INSULATING MATERIALS
Type of suitable heat insulating materials.
Material: mineral fibre; ceramic fibre; rock wool.
Form: sheets; mat; shells.
Specifications: specific weight of at least 245 kg/m 3 with limit working temperature of at least 1000°C.
Thermal conductivity X (400°C) < 0.1 W/mK
Thickness: as shown in the figures in the paragraph "MINIMUM SAFETY DISTANCES".
If the insulating material is not lining the walls, it must be fixed all over the surface of the walls with anchorage points every 30 cm.
Material coded “AGI Q132” or “ DIN 18895” is allowed for heat insulation.
1.9 MINIMUM SAFETY DISTANCES
If the floor around the fireplace is made of flammable material, it must be
protected with non-flammable material or be replaced with a floor of non-
flammable material.
This area may be recognised as follows. (Fig. 13)
On the perimeters of the fireplace "A", the floor must be covered for a distance
equal to the height "H" + 30 cm and in any case not less than 50 cm.
Example: for surrounds with H = 60 cm, the result is A = 90 cm.
"H = 60 cm" means the height from the floor to the grate.
1.10 PREVENTION OF DOMESTIC FIRES
The product must be installed and used in compliance with the manufacturer's instructions and European and national standards as well as local regulations.
When a flue pipe passes through a wall or a ceiling, special installation methods must be applied (protection, thermal insulation, distances from heat-sensitive
materials, etc.).
It is also recommended that all elements made of combustible or inflammable material, such as beams, wooden furniture, curtaining, flammable liquids,
etc. be kept outside the heat radiation range of the fireplace and at a distance of at least 1m from the heating block.
For other information, see the paragraph
"MINIMUM SAFETY DISTANCES".
The flue pipe, chimney stack, chimney and fresh air intake must always be free of obstructions, clean and checked periodically, that is, at least twice
during the seasonal period from the lighting of the fireplace and during its use. When the fireplace has not been used for some time it is advisable to carry
out the checks mentioned above. For further information, consult a chimneysweep.
Only use recommended fuels (see paragraph
"FUEL").
