The burner is to be tested to determine its waste gas
values.
Supervision
The persons charged with the operation of the units
have to control the units before starting to work to make
sure that there are no visible defects on the control and
safety devices and that all the protection devices have
been correctly set.
If defects are detected, the supervisor is to be informed.
If the detected defects jeopardize the unit’s operational
safety, the unit is to be put out of action.
Open-air Installation
Heaters operated in the open air must be so installed
and protected against atmospheric influence that they
do not cause any hazards or inacceptable annoyance.
We recommend that a burner cover (REMKO accesso-
ries) is used.
Installation in closed, well aerated rooms wi-
thout connection to a chimney
The operation of the units is admissible when the mini-
mum air quantity needed for combustion is supplied.
A safe exhaustion of the waste gases is to be ensured
to exclude inadmissible pollution.

Room Heating
For room heating, hot air generators may only be ope-
rated with a room thermostat (accessories). Make sure
that sufficient fresh air is fed to ensure perfect combus-
tion. Fresh air is to be fed preferrably through windows
and doors or through sufficiently dimensioned openings
in the outer wall.
Attention!
Avoid under- or overpressure in the room where the unit
is installed, as this would result in combustion troubles.
Please make absolutely sure that the suction and out-
going air opening is adapted to the fan power con-
cerned (see rating plate).
If this is not possible, the burner has to be equipped
with a separate air supply device to ensure perfect com-
bus-tion.
Safety Distances
Make sure to observe the following safety distances to
ensure a safe operation of the unit:
- towards the top, without waste gas pipe 3,0 m
- towards the top, fire-retarding ceiling 1.5 m
- towards the sides, non-burning objects 0.6 m
- blow-off side, 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. Suction and blow-off cross sections may not
be reduced.
Wa st e Ga s Pi p es
When the units are operated outside or in open rooms
you do not need a waste gas pipe. However, we recom-
mend that you use a waste gas pipe of 1 m length ( see
example 2 ) with a rain hood on top of it to prevent the
penetration of rainwater and dirt.
If the units are used as room heaters, it will be necessa-
ry to guide the waste gases outside.
The waste gas pipe components are to be laid in such a
way as to ensure that a minimum draft of 0.1 mbar is
guaranteed. Make absolutely sure not to generate
counterpressure
by inadequately laid waste gas pipes.
Generally a trouble-free operation can be ensured when
the waste gas pipes have been laid in an ascending
manner and assembled with vertical end pipes.
The waste gas pipes must reach at least beyond the ea-
ves but preferrably above the roofridge to avoid counter-
pressure due to bad weather conditions (e.g. wind).
All the waste gas pipe components are to be fastened
reliably. Their diameter may not be smaller than that of
the unit’s waste gas connection piece. A minimum di-
stance of 0.6 m must be kept from inflammable objects.
Waste gas components incl. fastening materials can be
supplied as accessories.
Hint!
Make sure that the waste gas pipes are correctly
installed with a condensate trap (see example 1), to
avoid damage to the combustion chamber through
humidity deposits (condensate) (see example 3).
