THE OPERATING ENVIRONMENT
For correct operation and even distribution of heat, the product must be placed where the air
required for combustion can flow.
The volume of the room should be no less than 15 m3.
Air must enter through permanent openings made in the walls (near the product) that reach
outwards with a minimum section of 100 cm2 without the protective grille. These openings (air
inlets) must be made in such a way that it is impossible for them to be obstructed in any way.
Air can also be drawn from adjacent rooms to the one that is to be ventilated, provided they have an
external air inlet and are not used as a bedroom or bathroom or where there is a fire hazard, such as:
garages, timber storerooms, warehouses of flammable materials, observing under all circumstances
the provisions of all the applicable standards in force.
If the product is placed too close to the wall it could cause overheating and damage the
plaster (yellowing, cracking, etc.).
POSITIONING AND RESTRICTIONS
In the case of simultaneous installation with other heating appliances, provide appropriate air inlets
for each one (according to the instructions of each product).
The product cannot be installed (except for sealed or closed operation appliances with
external ducted combustion air intake):
in bedrooms or bathrooms;
in rooms where there are liquid fuel appliances with continuous or intermittent operation
that draw the combustion air from the room they are installed in;
in rooms where there are B-type gas heating appliances, with or without domestic hot
water production and interconnecting rooms;
where another heating appliance is installed without an independent air flow.
It is forbidden to place the product in an explosive atmosphere.
BOILER ROOM
Check that the room meets the requirements and characteristics in compliance with the standards in
force. The room must also have suitable ventilation required for proper combustion. One must
therefore make openings in the room walls that meet the following requirements:
• They must have a section of at least 6 cm2 per each 1 kW (859.64 kcal/h). The minimum opening
section must in any case not be below 100 cm2. The section may also be calculated using the
following relation:
S = K * Q . 100 cm2
Where “S” is expressed in cm2, “Q” in kW, “K” = 6 cm2/kW
• The opening must be positioned in the lower part of an outer wall, preferably opposite to that in
which the smoke evacuation duct is located.
