In st a l l a t i on Requi r e-
m en t s
The heaters may only be installed and operated in com-
pliance with the relevant regulations, especially regula-
tions governing the installation and operation of fire-
places and furnaces.
Operators
The units may be operated only by persons who have
been trained in this field.
Installation
Install the heaters in a stable position.
Install and operate the heaters so as to avoid any ha-
zard to the personnel by fumes and radiation heat, well
as to avoid any risk of fire.
The heaters may only be installed and operated inside
rooms if they are supplied with sufficient air for combus-
tion and if the flue gases escape into the open through
flue-pipes.
The air supply is sufficient for combustion when, for
example, the cubic capacity of a room is at least ten
times the nominal thermal load of all heaters in the
room, and a natural exchange of air is ensured by me-
ans of windows and doors.
Heaters without waste gas pipe may be used in rooms,
provided that these are well aerated and the percentage
of substances which are injurious to health in the brea-
thed in air do not reach inadmissible concentrations.
The airing is sufficient when, for example,
1. the room capacity in m³ is at least 30 times the nomi-
nal thermal load in kW of all heaters in the room, and
a natural exchange of air is ensured by means of
windows and doors, or
2. there are air inlet and outlet openings, which cannot
be closed, near the ceiling and the ground; the size
of which in m² must be at least 0.003 times the nomi-
nal load in kW of all heating devices in the room.
Do not install or operate the heaters in rooms or areas
exposed to fire or explosion hazards.
Room Drying
The heaters may be operated in order to dry rooms with-
out evacuating the generated gases through waste gas
pipes outside, if the air supplied to those rooms is suffi-
cient for combustion. Persons are not allowed to stay
permanently in those rooms. Relevant prohibition signs
are to be fixed at the entrances.
Test
The units are to be tested depending on the operational
conditions when necessary, but a least once a year as
to their operational reliability. These tests are to be car-
ried out by an expert.

4
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.
Fresh airis fed from below;
waste gasesare exhausted towards the top.
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).

St ar t i n g
Make sure to charge a person with the operation and
supervision of the unit who has been instructed
sufficiently regarding the handlings concerned.
Prior to starting, the unit is to be checked to make sure
that there are no visible defects on the control and
safety devices, that the unit has been installed correctly
and that it has been properly connected to the mains.
•Install unit in a stable position.
•Make sure that air is supplied for combustion.
•Make sure that the air can be sucked in and be
exhausted freely.
•Avoid overpressure and underpressure in the room
where the unit has been installed.
•Make sure that enough fuel is supplied.
(only use clean fuel oil EL and diesel, respectively)
Attention!
A sufficient quantity of free-flowing fuel oil must be
available even with low outside temperatures.
Paraffine formation can start even at a temperature of
5° C. Adequate measures are to be taken to avoid this.
Hint!
Any additional clauses of the relevant building
regulations and technical rules for combustible liquids
(TRBF 210 and 280”) are to be observed.
The waste gas values of the oil-or gas-burner are to be
checked and adjusted properly by authorized experts in
accordance with the local conditions.
Connection to the Mains
The units are operated with alternating current of 230 V.
Connection to the mains is carried out by means of an
installed mains cable with earthing-contact plug.
Possibly required extension cables must be selected
according to the existing cable length, the unit’s
connecting line and the intended purpose.
All extension cables are to be used only after
having been removed from the roller.

2Hot Air Distribution
All the units are equipped with silent and nearly main-
tenance-free axial fans.
Hot air may be distributed only in accordance with the
fan capacity of the units concerned.
The possible hose/pipe lengths depend on the resis-
tance on the air side of the used air ducts. Air is prefer-
rably distributed through pipings or special hot air and
sheet hoses, respectively.
Please observe the following instructions when hot
air hoses are to be fitted:
•Please use exclusively those hot air hoses
(accessories) which have been approved by our com-
pany.
•The inside overlappings on the seams of the hot air
hoses must run with the air current direction.
•Make sure that the hoses and pipes, respectively, are
safely fastened to the unit’s outgoing air connection
piece.
•The pipes and hoses may not have sharp kinks and
bends in order to avoid heat accumulation.
•In thecaseofincreased suction temperatures or re-
sis-tance on the unit’s outgoing air side, the burner
can be switched off by the temperature controller
(TW) during the heating operation for a short time.
When the temperature has fallen the burner is restar-
ted automatically.
While the unit is operating, frequent startings of the
burner should be avoided.
When the temperature is too high on the unit’s out-
going air side, the heating-operation is interrupted
automatically for a longer period by the STB!
Attention!
The fan continues running to cool down the combustion
chamber and then stops later.
Never interrupt the connection to the mains before
the end of the whole after-cooling phase (except in
emergency situations).
The fan can start several times before final
switching off!
Our guarantee does not cover damages caused to
the unit by overheating!
