Equipment using gas type B is not permitted (refer to regula-
t
ions in force in the place of installation).
Using the stove or flue simultaneously with shared ventilation
systems is not permitted, whether with or without extractor
f
ans. Similarly the use of other devices or equipment, such as
air-conditioning systems or other heating systems which use
f
ans to circulate air, is not permitted. These devices can cause
the atmosphere around the stove to become pressurised even
if installed in adjacent, communicating rooms.
1.6 Capacity load of the floor
Check the load-bearing capacity of the floor, referring to the weight of the
product given in the paragraph “
TECHNICAL DATA”.
If the floor does not have a suitable load-bearing capacity, adequate coun-
termeasures must be taken, for example, by using a sheet metal plate to
distribute the load.
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:
a)
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 rela
tion to other adjacent heated or unheated rooms, …
b)
External factors: geographical position, average outdoor temperatu-
re,
exposure,
wind speed,
la
titude, 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 0.05 to 0.06 kW per cubic metre in a poorly insulated environ-
ment.
3 rooms measuring 20m2 X (H ceiling) 2.7m = 162 m3 (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”).
Rated power being equal, products with the Multi-fire system
can evenly distribute heat throughout the rooms to be heated.
