2.6 CONVECTION CURRENT

2.6.1 Natural convection

It is compulsory to open 2 or 4 hot air vents (see table 1) at the
top of the appliance. The entrance for the air supply convection are situated
at the lower backside of the Luna Gold+ and also through the opening that is
provided for the fan. These have been constructed in such a way that no air can
be blown out along here, not even with a fan. The stove is placed at least 20 mm
above the floor (if placed on the floor) to allow for natural convection.
A clearance of at least 4 dm3 , excluding the measurements of a dust filter, or at
least 6 dm3 , including the measurements of a filter, must be provided for in the
masonry. (Note: Remember to take the measurements of the clearance of the
grids into account.) (Pic.7a)
2.6.2 Convection by means of a fan (optional)
It is compulsory to open at least 2 hot air vents (see table 1). It is essential to
separate the air supply ducts and the air vents correctly in the masonry. Some
insulation material gets damaged in time, and it is essential to separate it from
the ventilation air supply, otherwise one runs the risk that it is sucked in and
spread in the house. It is therefore also advisable to use fixed insulation plates
(Promatec, HT-platen or promatec). The fan may be mounted either on the out-
side or on the inside, which even makes it possible to install a fan afterwards.

2.6.3 Hot air ducts

Thermally insulated ducts are essential for the optimal functioning of the ap-
pliance (these cause 'draught' in the convection air current). By using the maxi-
mum number of ducts (at least 2), the output is improved and the noise (that is
caused by the displacement) is reduced.
For the purposes of the installation of these ducts it is best to go vertically up-
wards first for at least 1m and then to change direction, making a rather wide
bend and avoid using a flue terminal grid with a small clearance because the
speed loss that this causes reduces the efficiency of the hot air vents.
M-design has developed its ideal hot air grids which have many advantages
