For the outdoor design when placed on the roof of the building, the installation
company is obliged to provide the heater with a lightning conductor in accordance
with ČSN EN 62 305.
Safety distances
The actual distance of the air heater from the flammable material must not be less
than the safety distance that is 200 mm, according to ČSN 06 1008:97. If this distan
ce
cannot be met, it is necessary to use a protective screen made of flammable material A or B.
The thickness of the protective screen must be at least 3 mm. The protective screen must
have a permanent position between the appliance and the protected material at a distance
(30 + 5 mm) from the protected material. The protective screen must extend beyond the
protected material to the nearest wall (ceiling) of non-flammable material, but at least
300 mm on the top and 150 mm on the sides. When using the protective screen, the
required distance can be reduced by no more than half.
If the heater is installed on the floor of flammable material, an insulating, non-
conducting pad is used in this case. The material used for insulating pads - the degree of
flammability A, B, must be resistant to the mechanical effects of the load. The dimensions of
the pad must be at least the same as the heater floor plan. The thickness of the insulating
pad must be at least 5 mm.
No flammable materials can be stored at the location of the heater, as this could
create a fire hazard!
Interconnection of air-conditioning circuit
The air-conditioning piping can be screwed directly onto the frame or through the
flange damping insert. The connection on the inlet and outlet side of the air heating
element must always be a full-area connection, in case of connection to sub-accessories
according to the specification of this accessory.
Connection to smoke flue
The installation of the smoke flue must comply with all applicable regulations and
must be carried out by a specialist company. For calculation of the smoke flue, 0 Pa per
throat and the mass flow of flue gases according to the burner setting and the heat input
(usually approx. 14 kg/h for every 10 kW of output) is considered.
Note : Each heater fitted with a gas overpressure burner must be connected through
a separate smoke flue to a separate chimney flue.
