Malfunction-free operation is guaranteed if the exhaust
system is installed in an ascending direction and with
vertical end pipes.
The exhaust system must terminate at least above the
height of the eaves but better still above roof height in
order to avoid counter pressure caused by weather-
related circumstances (e.g. wind).
All exhaust-pipe parts must be attached reliably. Their
diameter must not be smaller than that of the exhaust
nozzle of the device (
∅
150 mm).
The minimum distance of 0.6 m to combustible parts
must not be exceeded.
Exhaust-pipe parts including attachment material are
available as accessories.
Exhaust system
In the outdoors or in open rooms, the operation of the
device is also possible without an exhaust system.
However, we recommend a 1 m exhaust-pipe (see ex-
ample 2) with a rain hood placed on top so as to rule out
the penetration by rainwater and dirt.
If the device is used for temporary room heating, the
combustion gases may have to be removed to the exte-
rior. The exhaust-pipe parts must be laid in such a way
that a minimum suction of 0.1 mbar is guaranteed.
G
It must be made sure in all cases that counter
pressure due to an incorrect exhaust system is
ruled out.

arrangement.
Important hint.
Make sure that the waste gas pipes are correctly in-
stalled with a condensate trap (see example 1), to avoid
damage to the combustion chamber through humidity
deposits (condensate) (see example 3).
The lateral openings in the exhaust connection must not
be closed or covered.
Installation Instructions
The units are generally to be operated in accordance
with the safety rules, the building code of the land con-
cerned and the fire protection code.
◊
Avoid under or overpressure in the room where the
unit is installed, as this would result in combustion
troubles.
◊
Suction and blow-out cross sections may not be re-
duced
◊
It is prohibited to connect conduits or hoses to the
unit blow-out opening.
◊
Make sure that the technical regulations for combus-
tible liquids are observed when mobile fuel holders
are installed.
Outside Installation
◊
The units are to be installed outside and to be pro-
tected from atmospheric effects to avoid damage.
◊
Make sure that no danger or inadmissible annoy-
ance is caused by the operation of the unit.
Room Heating
◊
For room heating, hot air generators may only be op-
erated with a room thermostat (accessories).
◊
Make sure that sufficient fresh air is fed to ensure
perfect combustion. Fresh air is to be fed preferably
through windows and doors or through sufficiently di-
mensioned openings in the outer wall.
Safety Distances
◊
Make sure to observe the following safety distances
to ensure a safe operation of the unit:
– towards the top, fire-retarding ceiling 1,5 m
– towards the sides, non-burning objects 0,6 m
– blow-off side, with non-burning objects 3,0 m
– suction side, for perfect air supply 1,0 m
◊
The floor and the ceiling must be from fire-retarding
materials.
Electric Connection
◊
The unit are operated with 230 V alternating current.
◊
Electric connection is carried out via a fitted mains
cable with shockproof plug.
◊
Possibly required extension cables must be selected
according to the existing cable length, the unit’s con-
necting line and the intended purpose.
G
The electric connection of the unit is to be carried
out via a special supply point with fault current
safety switch.
G
All extension cables are to be used only after
having been removed from the roller.
