1.3 Instructions
For installation and for connection of flue, the requirements of the Fire Regulations
(FeuVO in Germany) apply, as well as local building regulations such as the following
technical standards DIN 18896, DIN 4705, EN 13384, DIN 18160, EN 1856-2 and EN
15287. In order for the stove to function correctly the chimney to which you want to
connect the stove must be in good condition.
1.4 Place of installation
The stove draws the air required for burning from the surrounding room. You must
ensure that sufficient air can be drawn in through non-sealed windows and outside
doors. In addition you must ensure that a room volume/heat capacity ratio of at least 4
m³ per kW nominal heat capacity is available. If the volume is less than this, then air
vents can be used to provide access to further air supply in other rooms (connecting
vents min. 150 cm²).
1.5 Air supply
A constant supply of oxygen or air is required for the combustion process. Normally the
air available in the room where the stove is installed will be sufficient.
NOTE: In the room where the stove is installed or in the neighbouring rooms there
must not be any air extractors or similar equipment. These could cause
considerable operating problems and even represent a risk. Consult the
local authority responsible for approving heating systems.
NOTE: The room where the stove is to be installed must not have equipment such
as extractor hoods, ventilation systems etc. which could mean that that
room or neighbouring rooms have reduced air pressure.
1.6 Safe distances
Ensure that the walls at the sides and behind the range are not constructed of
flammable material and/or clad or coated in flammable material, if they are less than
30 cm of the side from the combustion chamber, and 30 cm of the side from the oven.
Plastic or wooden furniture or similar must also be kept at a distance of more than
20 cm from the back of the range.
No flammable or heat sensitive material should be within 70 cm of the front of the range
in its field of radiation.
If there is a floor covering or a floor in front of the fire door opening which is flammable
or otherwise sensitive to heat then it should be covered with a layer on non-sensitive or
flammable building material. The layer must cover an area of 60 cm from the front of the
fire door opening and also a minimum of 40 cm either side of it. Wall mounted
cupboards over the range must have a minimum clearance of 70 cm from the hob plate
of the range.
