Safety Instructions

Make sure to observe relevant local building and fire
protection codes and abide by professional association
regulations when the units are in operation!

◊ Before performing any maintenance or repair work,

make sure to unplug the units from the power supply.

Remove fuses or switch off the customer-supplied
main switch.

It is not sufficient to switch off the units with the
operating switch!

G

◊ The units may only be operated by persons who

have received proper training in their operation.

Description of the Unit

The units (automatic heaters) have been designed for
universal, fully-automatic and smooth operation. They
are fired directly with heating oil, diesel or natural/liquid
gas. The VRS 20 INOX has only been designed for op­eration with heating oil or diesel.

Function and Design
The units have been designed for operation with a

separate forced-air burner in single-stage operation. 2­stage burners may only be operated to prevent conden­sation from accumulating during startup in partial load
range.

◊ The units must be installed and operated in such a

way that people are not exposed to radiant heat and
fires cannot occur.

◊ The units may only be installed and operated in

closed rooms where the units have adequate air
supply for combustion.

If this cannot be guaranteed, a separate burner­driven device that sucks in fresh air from the outside
must be installed.

◊ The units may only be set up on a non-flammable

surface.

◊ The units may only be attached to non-flammable,

sturdy structures or ceilings made from the materials
with sufficient load-bearing capacity.

The units are to be attached with sturdy mounts
which are fixed on the unit.

◊ The units may not be set up or operated in surround-

ings susceptible to fire or explosions.

◊ The units must be set up outside of traffic zones,

e.g. away from cranes.

A safety zone of 1 m is to be maintained around the
units.

◊ The protective air suction grille must always be kept

free of dirt and loose objects.

◊ Never insert foreign objects into the units.
◊ Do not expose the units to a direct stream of water.
◊ Never let water get inside the units.
◊ All of the units’ electrical cords are to be protected

from damage (e.g. caused by animals, etc.).

It is essential to connect the units to an exhaust system
approved by the state building authorities.

The units are equipped with single setting, quiet axial
ventilators with drive motors requiring little maintenance
and with integrated switches and control devices de­pending on the type of unit.

The units meet the basic safety and health require­ments found in the relevant EU regulations. They are
safe and easy to operate.

The robust design and clean processing of these high­quality units ensure a long service life and smooth op­eration. They can also be assembled quickly, easily and
affordably and are easy to service.

Operating Locations of the Units

The units are direct-fired devices that supply instantane­ous heat. They are only used for industrial and commer­cial purposes. There are generally no restrictions as to
where they can be used.

REMKO automatic heaters supply heat or regulate the
temperature of:

− Workshops

− Warehouses

− Exhibition spaces

− Trade show spaces

− Temporary structures for warehousing

− Showrooms

− Greenhouses etc.

These units have not been designed for heating
private residences or similar spaces.

G

Do not bypass or block safety mechanisms while
the unit is in operation.

Proper Use

The units have been designed and equipped exclusively
for industrial and commercial heating and ventilation
purposes.

The manufacturer assumes no liability for damage re­sulting from non-compliance with manufacturer specifi­cations and legal requirements, or if modifications are
made to the units.

Operation

After switching on the unit by setting the operating
switch to “Heizen” (heating), the forced-air burner turns
on automatically. The combustion chamber with heat­exchanger now heats up until the target temperature is
reached.

After the set target temperature is reached, the air sup­ply fan switches on automatically. Warm air is blown
out.

If heating mode is controlled via a room thermostat or
other temperature regulating device (operating switch
set to “Heizen” (heating), the units function fully­automatically based on amount of heat required.

All of the unit functions are performed automatically and
monitored by the automatic burner relay (part of the
forced-air burner) and the integrated temperature con­trol thermostat.

After the device is switched off with the operating switch
or the room thermostat, the air supply fan runs for a cer­tain amount of time to cool the combustion chamber
with heat-exchanger and then switches off. This proc­ess can be repeated several times.

Never interrupt (except in emergency situations)
the power supply until the cool-down phase is
completely finished.

G

Our guarantee does not cover damages caused to
the unit by overheating.

Safety Facility

If the flame burns irregularly or goes out, the unit is
switched off by the automatic burner relay. The unit may
only be restarted after the automatic burner has been
manually released.

The temperature monitor (TW) regulates the tempera­ture of the unit as well as the outgoing air current via the
burner in heating mode. The temperature control ther­mostat (TR) regulates the fan.

The safety temperature limiter (STB) interrupts opera­tion of the unit or burner when extreme overheating oc­curs or if the TW ceases functioning. The STB can only
be manually released after the unit has cooled.

Before the STB is released (to restart operation),
the reason the STB was activated must be deter-

G

mined.

For units in the 400 V series, the fan motor is also moni­tored by a thermal overcurrent relay. If the motor be­comes overloaded, operation is interrupted by the relay
and the red malfunction lamp “Ventilator” (fan) on the
control box lights up. Release is only possible after the
control box has been opened.

It is not necessary to limit the capacity in single­stage burner operation for the warm air generator.

G

Prior to Assembly

When setting up the units, the relevant regional building
and fire protection codes of the respective region must
be observed.

Selecting the Setup Location

When selecting a location to set up the units, the re­quirements must be adjusted with respect to:

◊ Fire protection and operating hazards.
◊ Function.

When the units are used to heat rooms, when it is
necessary to adjust to the amount of pressure in the
room, etc.

◊ Operating needs.

Heating requirements, rated air output, need for cir­culation or outside air, humidity, room temperature,
air distribution, space needs, etc.

◊ How the unit is connected to the exhaust system.
◊ Access for monitoring, assembly, repair and mainte-

nance work.

◊ Ratio of room volume to total rated air capacity espe-

cially for naturally ventilated rooms.

The unit must be set up and assembled in such a
way that it is easily accessible for monitoring, re-

G

pair and maintenance work.

Units with a rated heat output of up to 50 kW may usu­ally be set up outside of heating rooms when the Ger­man ordinance on heating systems is observed. Units
with a rated heat output of more than 50 kW must be
set up in heating rooms.

As an exception to this, heating appliances for solid, liq­uid or gaseous fuels with a total rated heat output of
more than 50 kW may also be set up in other rooms if
their use requires this (e.g. single heating appliances
such as fan heaters) and these heating appliances can
be safely operated.

Here, the German state building authorities’ “Guidelines
for setting up furnaces with a total rated heat output of
more than 50 kW in rooms other than heating rooms”
must be observed.

The guidelines prohibit erecting furnaces when poten­tially dangerous concentrations of hazardous sub­stances are present in accordance with the substance
ordinance.

The dangerous concentration must be checked in the
setup room and any accessible adjacent rooms to see
whether the prohibition applies.

In rooms where highly flammable materials or mixtures
are being processed, stored or produced in quantities
that are hazardous should they ignite, exceptions may
be made if appropriate measures are taken to ensure
that the heating appliances cannot cause the materials
or mixtures to catch fire.

Important Information about Safe Setup

Air Supply for Combustion

◊ The units may only be set up and operated in rooms

where there is enough air for combustion and the ex­pelled air is guided to the outside via an exhaust sys­tem.

◊ Units dependent on air in the room may only be set

up in rooms or buildings from which air is suctioned
out by means of fans (such as ventilation or exhaust
systems) if:

1. Safety mechanisms prevent the units and the air
suctioning system(s) from operating simultane­ously.

2. The expulsion of exhaust is monitored by special
safety devices.

3. The exhaust produced by the units is expelled by
means of the air suctioning system(s).

4. The design or dimensions of the system ensure
that no dangerous negative pressure can be pro­duced.

◊ The units must be placed firmly on a suitable, non-

flammable surface outside of traffic zones, for exam­ple, away from cranes.

◊ The units must be set up and operated in such a way

that people are not exposed to exhaust or radiant
heat and fires cannot occur.

◊ The units must be set up in such a way that they do

not cause any hazards or unreasonable annoyances,
e.g. tremors, vibrations or noise.

◊ The units must be set up and installed in such a way

that they are easily accessible for monitoring, repair
and maintenance work.

◊ Operating elements which can result in dangerous

operating conditions when used improperly must be
protected from unauthorised operation if they are
generally accessible.

◊ When attaching mixed air flaps (accessories), they

must be connected against the flow of air and ensure
a minimum cross-section for an adequate external
air rate.

◊ The units may not be set up or operated in rooms or

areas susceptible to fire or explosions.

Power Supply
Prior to performing the electrical installation in line with

local requirements, check whether it is possible for even
a temporary power overload to cause an impermissible
undervoltage.

To connect the units, the line cross-sections are to be
placed in such a way that they do not caused the burner
voltage to lower to an impermissible level when the fan
is started.

An adequate supply of air for combustion must be en­sured by meeting the relevant building requirements.

Excerpts from the German fire ordinance:
(1) For furnaces with a total rated heat output of up to

35 kW that are dependent on the air in the room,
evidence of an adequate air supply for combustion
has been provided if the furnaces are set up in a
room that has:

1. A minimum of one door to the outside or a win­dow that can be opened (rooms with a connec­tion to the outside) and a room capacity of at
least 4 m3 per kW of total rated hear output or

2. An opening leading to the outside with a cross­section of at least 150 cm2 or two openings
which are each 75 cm2 or lines to the outside
with equivalent cross-sections for air flow.

(2) For furnaces with a total rated heat output of more

than 35 kW and less than 50 kW that are depend­ent on the air in the room, evidence of an adequate
air supply for combustion has been provided if the
furnaces are set up in rooms that meet the require­ments of Para. 1, No. 2.

(3) For furnaces with a total rated heat output of more

than 50 kW that are dependent on the air in the
room, evidence of an adequate air supply for com­bustion has been provided if the furnaces are set up
in rooms that have an opening or a line leading to
the outside.

The cross-section of the opening must be at least
150 cm² plus and additional 2 cm² for each kW of
rated heat output which is above 50 kW.

The lines’ cross-sections must have equivalent
measurements for air flow.

The required cross-section may not divided among
any more than 2 openings or lines.

(4) Combustion air openings and lines may not be

closed or blocked unless the safety mechanisms
can ensure that the furnace can only be operated
when the flap is closed.

The required cross-section may not be constricted
by the flap or the grille.

(5) As an exception to Paras. 1 to 3, for furnaces de-

pendent on air in the room, evidence of an ade­quate air supply for combustion can be provided
other ways.

For example by:
A continuous line to the outside with a sufficient

cross-section that is attached to the burner or its lin­ing. This must be adjusted to the suction capacity of
the burner and the line resistances (including the
protective air suction grille) so that combustion is
assured.

6

Fuel Supply

Wall Assembly

Particularly for heating oil lines, make sure that the
cross-section of the lines corresponds to the suction
height, the total line resistance and increased viscosity
at lower temperatures and, if necessary, it is possible to
connect an oil transport device.

The lines must be placed in such a way that they are
easily ventilated and are protected from corrosion and
mechanical damage.

The measured pressure of the suction line should
not exceed -0.3 bar. It may be a maximum of -0.4 bar.

G

Heating Rooms

The units only may be operated in closed rooms or
warehouses if they have been equipped with a suitable
room temperature control thermostat (room thermostat).

The wall where the unit is to be assembled may not be
made of flammable materials. Its load-bearing capacity
must be tested and, if necessary, reinforced.

Consoles must be anchored firmly to the wall and the
units attached here. There must be adequate room to
perform maintenance work on the heat-exchanger,
burner, fan and exhaust system.

Assembling Suspended Units
The units may only be attached to sturdy structures or

ceilings that are made of non-flammable materials and
have adequate load-bearing capacity.

Sturdy mounts fixed on the unit are used to attach it. In
addition, the requirements listed in the section “Wall As­sembly” must be observed.

Unit Setup

When setting up the units, the regional provisions and
regulations must be observed.

The units may only be operated with accessories that
have either been approved by the manufacturer or sup­plied with the units.

Proceed as follows to set up the units:

Setup and Assembly

Setup on the Ground
The units must be placed firmly on non-flammable sur-

face outside of traffic zones, e.g. away from cranes.
A safety zone of 1 m must be maintained around the

units to protect them from damage in commercial
rooms, to ensure unhindered access for maintenance
and repair work on the unit and burner and, if neces­sary, to prevent air intakes and outlets from blockage.

This safety zone is to be identified with a warning sign
that says:

Maintain a Safety Zone of 1 m

We recommend clearly marking heavily trafficked ar­eas.

Outside Setup
Units that are set up outside must be adequately pro-

tected from weather conditions so that they do not have
any harmful effects or cause any unreasonable annoy­ances during operation.

The units may only be equipped with armatures and
control devices that are suitable for outside use. If not,
the control devices and switches must be protected ac­cordingly.

1. Remove the transport pallets or crates, protective

plastic or other packaging material before set up/
assembly.

2. Check the units for any damage.

3. Place the units firmly on a suitable surface.

4. If necessary, secure the units with suitable material.

5. Make sure an adequate distance is maintained to

flammable materials.

6. Make sure that air is supplied only via the air intake

openings intended for this purpose.

7. Make sure that there is a sufficient supply of air for

combustion.

8. If there are unfavourable pressure conditions in the

setup room or strong air impurities, install a burner­driven device that sucks in fresh air from the outside.

9. Make sure that air can flow freely into and out of the

units.

Heating Oil Connection

Make sure that there is an adequate supply of fuel.
◊ The suction line must be equipped with a valve at the

end of the hose in the tank.

◊ Even when outside temperatures are low, a sufficient

amount of heating oil must be able to flow freely.
Paraffin can accumulate at temperatures starting at
approximately 5 °C depending on the quality of the
heating oil.

Appropriate measures must be taken to prevent this
from happening.

Gas Connection

Depending on the capacity of the unit, the required
quantity of gas must always be available and the neces­sary gas pressure present during unit operation.

Gas pressure regulators and shut-off valves are to be
supplied by the manufacturer.

The line cross-section must correspond to the connec­tion values of the units, the total line resistance and the
gas pressure.

Prior to initial operation, the gas supply line must be
thoroughly cleaned and tested for impermeability!

G

Burner Installation

The forced-air burner supplied by the manufacturer is
attached to the front of the unit with a clamp flange.

You must observe the following:
◊ Only forced-air burners with automatic burners that

have a 5 sec. safety period may be used.

◊ It is not necessary to limit the capacity in single-

stage burner operation for the warm air generator.

◊ The burner must be adjusted to the full heat load of

the unit.

The thermostat sensor may not be exposed directly to a
particularly cold or warm air current.

The process is the same for installation of an automatic
day/night temperature regulator (accessory).

Important Instructions for Unit Assembly

Make sure to observe the following general instructions
as well.

◊ Operating devices for the units and the fuel supply

must be able to be operated directly from the
ground.

◊ The operator must provide any support material nec-

essary for monitoring, maintenance and repair work.

Fan Motor Connection

The units are completely wired at the factory.
In the event of changes or if the fan is replaced, make

sure to connect the motor and condenser to one an­other properly and ensure that the rotational direction of
the motor is correct.

◊ The combustion chamber may not be operated be-

low capacity.

◊ The exhaust temperature may not fall below 160 de-

grees Kelvin above the room temperature.

Condensation accumulation.

◊ Follow the operating instructions of the burner sup-

plied by the manufacturer.

◊ If burners from other manufacturers are used, they

must be checked for compatibility with the unit.

Electrical Installation

The electrical connection of the units may only be per­formed by authorised personnel in accordance with the
relevant regulations (including any local ones).

An easily accessible emergency switch must be at­tached in the setup room.

The emergency switch must be protected from unau­thorised use.

Thermostat Connection

The room thermostat (accessory) or day/night regulator
(accessory) is connected via special connections.
Please follow the appropriate wiring diagram for con­nection.

Exhaust Connection

Examples of Use

The unit is to be connected to suitable exhaust systems
whose design has been approved.

Installation of an exhaust system always requires
a permit.

G

Exhaust systems are structural systems located either
in or on buildings whose sole purpose is to expel ex­haust from heating appliances safely above the roof.

When planning for the exhaust system, please observe
the following:

◊ The exhaust system must be installed and assem-

bled properly and in accordance with the relevant
regulations.

◊ The dimensions of the exhaust lines must be ad-

justed to the capacity of the unit and the construction
height.

◊ The dimensions of the exhaust systems must ensure

that the exhaust is expelled to the outside regardless
of the operating conditions and guarantee that no
positive pressure is produced in the rooms. These
dimensions are based on the cross-section and
height, and to the extent required, the heat penetra­bility resistance and internal surface.

◊ The exhaust system openings must stick out at least

40 cm beyond the top of the roof or be at least 1 m
away from the surface of the roof.

◊ If impact pressures, e.g. from fall winds or neigh-

bouring buildings, are anticipated, the top of the
chimney should be shaped accordingly.

◊ The exhaust system must be attached securely and

properly according to the manufacturer’s specifica­tions.

◊ In roof structures, the exhaust system must be led

through a pipe casing or a chute to allow the exhaust
line to expand when heated.

◊ The unit connection must be impermeable and se-

cured with rivets or screws from becoming acciden­tally loose.

◊ It is preferable to have a horizontal exhaust line that

is as short as possible.

Incline 2 % = 2 cm/m.

◊ You should plan to have a closable opening for per-

forming measurements at a distance of 2 x ∅ ex­haust pipe behind the unit connection.

Under certain circumstances, it is possible to meas­ure the exhaust opening.

Prior to Initial Operation
of the 400 V Series

Fan Motor Operation

Check the drive.

1. Check the rotational direction of the fan.

2. Check the initial tension of the drive belt.

3. Check that the tightening screws of the complete
drive are secure.

Measuring the rated current and/or current consump­tion.

1. To prevent inaccurate measurements, open the grille
in the air duct or the blow-out cover.

2. Attach all air suction grilles to the unit.

3. Check the available power supply.

4. Measure the current.
◊ Rated current for direct start.

The measured rated current may not exceed the
value on the type plate of the motor. The thermal
overcurrent relay must be adjusted to the rated
current of the drive motor.

◊ Rated current for Y / ∆ start.

The measured rated current may not exceed the
value on the type plate of the motor. Multiply the
rated current of the drive motor by a factor of 0.58
and adjust the thermal overcurrent relay to the
calculated value.

Each phase should be measured separately to pre­vent inaccurate measurements.

G

Thermal Overcurrent Relay
To check the function of the overcurrent relay or its set

value, remove a fuse. If the unit is functioning and set
properly, the relay should activate after approximately
30 seconds.

Important Information about the Thermal Overcurrent
Relay

The thermal overcurrent relay may only be operated
when the relay is set to manual (H). The relay may not
automatically switch on again after it has cooled. When
the relay is set to automatic (A), the possibility that dam­age will occur cannot be ruled out. There is no guaran-

tee claim!

Before Starting

Initial operation of the unit and its forced-air burner must
be performed by the manufacturer or one of its author­ised service representatives.

During this process, all regulating, control and safety
mechanisms must be checked to ensure that they are
functioning properly and set correctly.

◊ Make sure that the fan’s screws and bolts and

burner attachments are secure.

◊ Check the tension of the drive belts.

If applicable.

◊ Open the blow-out grille if necessary and adjust it as

required.

◊ Check the settings of the temperature monitor and

the temperature control thermostat.

Burner approx. 80 °C; fan approx. 40 °C.
Factory setting at the VRS 20 INOX unit.

◊ Switch the customer-supplied main switch or fuse

on.

◊ Set the room thermostat to a higher value than the

current room temperature.

◊ Open the fuel supply and set the operating switch to

“Heizen” (heating).

If the oil burner was supplied by the manufacturer,
the burner start is delayed as a result of the standard
oil preheating process (up to VRS 60).

◊ Adjust the throughput for the heating oil or gas to

meet the heating capacity of the unit.

See the unit’s type plate.

◊ Set the burner to the optimum values in accordance

with the manufacturer’s specifications.

◊ Measure the chimney draught when cold and hot.
◊ The exhaust temperature difference (∆t) may not fall

below 200 Kelvin or below 160 Kelvin for the Inox
series.

This prevents the temperature from falling below the
dew point which causes corrosion in the heat­exchanger.

◊ Keep a protocol of measurements and submit it to

the operator for safekeeping. Familiarise the opera­tor with the system.

◊ Give the statement confirming the authorised com-

pany status and the company certificate of the re­spective installation company to the relevant authori­ties.

Current Consumption too High

If the motor is consuming too much current despite a
proper electrical connection and adequate power sup­ply, the thermal overcurrent relay may not be set higher
or bypassed under any circumstances.

To correct the problem, the air intakes and outlets
(possible air compression) must be checked and appro­priate action taken.

10

Information on Gas-Fired Units.

For initial operation of gas-fired units, installation may
only be performed by a contracted installation company
(except in gas supply companies) or, for liquid gas, by a
liquid gas supply company.

Starting

Heating Mode

1. Turn the customer-supplied main switch or the fuse
on.

2. Open the fuel supply.

3. Set the operating switch to
“Heizen” (heating) or “I”.

4. Adjust the room thermostat
to the room temperature you
want.

When heat is necessary, the forced-air burner switches
on automatically. The air supply fan only switches on
once the target temperature has been reached. This
prevents cold air from being blown out. The unit now
functions fully-automatically to maintain the set room
temperature.

Ventilation

Maintenance and Service

The operator must have the unit checked and serviced
as necessary, at least once a year, by a representative
of the manufacturing company or another authorised in­dividual in accordance with the operating conditions.
The units must be checked for operational readiness,
functional safety, efficiency and compliance with emis­sion limits.

The operator must be informed if defects are found. He
must then have the unit serviced immediately or its
components replaced.

The following applies:

Maintenance work on limiting devices, self­adjusting devices and flame monitoring devices as
well as on other safety mechanisms may only be
performed by the respective manufacturer or his
representatives.

On the other hand, the individual contracted to
service the unit may only replace components or
assemblies with those provided by the manufac­turer or his representatives.

Adjustments or maintenance work on the unit or
forced-air burner may only be performed by

G

authorised personnel!

1. Set the operating switch to
“Lüften” (fan) or “II”.

2. Keep in mind that the unit’s
fan runs continuously.

It is not possible to control it
with a thermostat

Unit Shut Down

1. Set the operating switch to
“0”.

2. Keep in mind that the air sup­ply fan continues running to
cool down the heat-exchanger
and can run several times
before the unit is finally
switched off.

Never interrupt (except in emergency situations)
the power supply until the cool-down phase is
completely finished.

G

Our guarantee does not cover damages caused to
the unit by overheating.

3. If the unit is taken out of op­eration for a longer period of
time, the customer-supplied
main switch or the fuse
should be switched off and
the fuel supply closed off.

Regular Cleaning and Maintenance
Dust and dirt must be cleaned from the unit including

from the heat-exchanger, combustion chamber and
forced-air burner. Combustion residue in the combus­tion chamber and in the heat-exchanger must be re­moved.

Prior to doing any maintenance or repair work on
the unit, unplug it from the power supply. It is not
adequate to switch off the unit with the operating

G

switch!

The V-belt tension and the motor mount must be
checked on a regular basis.

Parts that wear out, e.g. flue gas brakes, seals, oil filter
inserts, oil nozzles, etc. must be checked, cleaned and
replaced if necessary.

Important Information on Servicing the Unit

◊ If the cleaning and burner adjustment intervals are

not observed, the guarantee becomes null and void.

◊ It is therefore absolutely necessary to keep records

that work has been performed by authorised person­nel in addition to creating standard protocols.

◊ We recommend entering into a maintenance con-

tract for the regularly scheduled maintenance and
service work.

After maintenance work is complete, conduct an
electrical safety test.

Troubleshooting

The unit was subjected to repeating testing during pro­duction to ensure that it functions properly.

However, if you still experience functional problems,
please refer to the list below.

For safety purposes, repair work on the electrical
components and the burner may only be per-

G

formed by authorised personnel.

The unit does not start

1. Check the power supply

2. Check the fuses in the control box.

Only for units in the 400 V rotary current series.

3. Check the safety temperature limiter.
If the safety temperature limiter (STB) has been acti-

vated, the reason the unit overheated must be deter­mined. The following are possible causes:

◊ The unit could not cool down because the

power supply was interrupted. Even short inter­ruptions can activate the STB.

◊ The temperature of the air being blown out is

too high because the grilles have not been prop­erly adjusted.

◊ The fan was overloaded and the thermal over-

current relay of the 400 V series was activated
or the thermal contacts in the fan motor of the
230 V series were activated.

◊ The V-belt of the fan drive is loose or defective.
◊ Air intakes and outlets are blocked.

4. Check the operating and/or main switch.

5. Check the room thermostat setting.

The room thermostat must be set higher than the
room temperature.

6. Set the operating switch to “Lüften” (fan) or “II”.

If the air supply fan starts now, look for the problem
in the burner.

◊ Check whether the burner malfunction control lamp

on the oil firing device is illuminated.

If so, release the relay by pressing the malfunction
button. The malfunction light goes out and the burner
tries to start. Keep in mind that some burners have a
delayed start due to the oil preheating process for
some units.

If, after the start phase, the burner switches off due
to a malfunction, you may only re-release it after
waiting 5 min. Additional releases are strictly pro-

G

hibited as there is a risk of explosion.

The air supply fan does not start

◊ Set the operating switch to “Lüften” (fan) or “II”.

The air supply fan should now start.

◊ Check that the fan and the fan drive are running

smoothly.

◊ Check the V-belt on the fan drive.
◊ Check the electric cord on the fan motor for damage.
◊ Check whether the capacity of the fan was ex-

ceeded.

The thermal overcurrent relay (400 V series) or the
thermal contacts (230 V series) in the fan motor
have been activated.

◊ Check the operating capacitor of the fan.

Only for the 230 V series.

◊ Check that the temperature control thermostat (TR)

is working properly.

Please carry out an electrical safety test after hav­ing finished service on the unit.

G

Should the unit still not function properly after per­forming these checks, please contact an author-

G

ised service centre.

The burner does not start

◊ Check whether the fuel filter is dirty.
◊ Check whether the shut-off valve of the fuel filter is

open.

◊ Check that there is enough fuel in the fuel container.
◊ Check whether paraffin has accumulated in the heat-

ing oil.
This can occur at temperatures below 5 °C.

◊ Check oil lines for damage.

Leaks can cause air intake.

◊ Use suitable means to ensure that the safety tem-

perature limiter (STB) and the temperature monitor
(TW) are functioning properly.

◊ Check the sensors and capillary pipes of the TW and

STB for damage and ensure that the sensor has
been properly positioned.
