Safety information Unit description

Operation of the heaters must always take place in compliance with
the local building and fire protection regulations and regulations of the
employers‘ liability insurance associations.

The heaters were subjected to
extensive material, functional and
quality inspections and tests prior
to delivery. However, the heaters
may constitute a hazard if used by
untrained personnel, improperly or
not for the intended purpose.

The following information must be
observed:

■ The heaters must only be used

by persons who have been
trained in its operation.

■ The heaters must be installed

and operated in a manner that
excludes any risk to persons
through radiated heat and the
risk of fire.

■ The heaters must only be in-

stalled and operated in rooms if
they are supplied with a suffi­cient air volume for combustion.

If this cannot be ensured, the
burner must be supplied with
fresh air from outside via a
separate air intake system.

■ The heaters must only be

installed on a flame-retardant
surface.

■ The heaters must only be

attached to constructions
designed to the take the weight
or to ceilings of flame retardant
materials with sufficient load
bearing capacity.

■ Attachment must take place

using suitable anchors to be atta­ched to the heater.

■ The heaters must not be installed

and operated in locations
where there is a risk of fire and
explosion.

■ A protection zone of 1 m dis-dis-

tance must be kept free.

■ The air intake grilles must always

be kept free of dirt and loose
objects.

■ Never insert foreign objects into

the heater.

■

The heaters must not be ex-The heaters must not be ex-

posed to a direct jet of water,
e.g. high-pressure cleaning

equipment, etc.

■ Never allow water to enter the

inside of the heater.

■ All electrical cables of the heaters

must be protected against dam­age (e.g. also from animals).

■

Portable fuel tanks must only be

installed and used in compliance
with the technical directives for
flammable liquids „TRbF 20“.

NOTE

Only type tested hot air heat­ers with forced-air oil burners
complying with
DIN EN 230 and DIN EN 267
must be used.

ATTENTION

Where delivery from the
factory takes place without fan
burner and a different make of
burner is used, the suitability
of the burner for the particular
type of hot air heater must be
ensured.

The heaters are stationary, directly
fired hot air heaters with heat ex­changer and chimney connection.
The heaters can be fired with fuel
oil EL, diesel fuel and liquid or
natural gas.

The heaters are designed
exclusively for operation with
separate fan burners in single-

stage operation.

Standard two-stage fan burners
can also be used to prevent the
formation of condensation during
start-up (as starting relief) in the
partial load range.

For reliable discharge of the
exhaust fumes via the roof, the
heaters must be connected to a
suitable chimney system.

The heaters are provided with
standard single-stage, low noise/
low maintenance radial fans and
mounted and electrically wired
switching and control units.

The heaters are built to give many
years of efficient service due to
their robust design and the use of
high-quality materials.
Further plus points include quick
and easy installation and ease of
servicing.

The heaters comply with the basic
health and safety requirements of
the pertinent EU regulations and
are easy to operate.

NOTE

The heaters are not suitable for
domestic heating or similar.

■ The heaters must be installed

outside traffic zones, e.g. also
the operating areas of cranes.

Heater applications

Mode of operation

The directly fired hot air heaters
supply instantaneous heat.
The heaters are designed exclu­sively for industrial and commercial
use.
The heaters can be fitted with inlet
and outlet air ducts with appropri­ate dimensioning.

There are generally no operating
restrictions with regard to the site
of installation.

Heater applications also include:

■

Heating workshops

■

Heating warehouses

■

Heating exhibition halls

■

Heating fair halls

■

Heating light-weight construc-Heating light-weight construc-

tion halls

■

Heating showrooms

■

Heating in horticulture and

agriculture

After switching on the heaters by
setting the switch to the „Heat“ or
„I“ position, the forced-air burner
starts.

The „Burner“ indicator light on the
control box lights up for control
purposes in the case of the 400V
heater types.
The combustion chamber with
heat exchanger is now heated.

After reaching the set tempera­ture, the supply air fan switches on
automatically.
The „Fan“ indicator light on the
control box lights up in the case of
the 400V heater types.
Hot air is blown out.

When using a room thermostat,
the described sequence is auto­matically repeated depending on
the heat requirement.

All heater functions take place
fully automatically and are reliably
monitored by means of the triple
function combination controller
and burner relay (integral part of
the force-air burner).

In the event of irregularities or
extinguishing of the flame, the
burner is shutdown by the burner
relay and interlocked.

The fault indicator light of the
burner relay and the „Burner“
fault indicator light on the control
box light up in the case of the
400V heater types.
Restarting can only take place after
manual release of the burner relay.

The safety temperature limiter
(STB) interrupts the burner func­tion on overheating.
Manual release of the STB can take
place only when the heater has
cooled down.

The fan motor in the case of the
400V heater types is monitored
by means of a thermal overcurrent
relay.

On motor overload, operation is
interrupted by the relay and the
red „Fan“ fault indicator light on
the control box lights up.
Release is only possible after reset­ting the relay in the control box.

The heaters are intended
exclusively for industrial and
commercial use. They are not
intended for domestic heating
or similar.

After switching off the heater via
the switch or room thermostat,
the supply air fan continues to run
until the combustion chamber and
heat exchanger have cooled down
and subsequently switches off
automatically.

ATTENTIONATTENTION

The heaters must never be
disconnected from the mains
supply before the cooling
down phase has ended (except
in emergency situations).

NOTE

Before releasing the burner
relay or overcurrent relay,
the cause of shutdown must
always be determined first.

Safety devices

Triple function combination controller according to DIN 3440

Oil or gas-fired hot air heaters must be fitted with intrinsically safe
control devices complying with DIN 3440.

REMKO triple function combination controller

Controller shown without housing cover

Triple function combination
controller

The triple function combination
controller has a sensor monitor
and is cold resistant to -20°C.
The heater switches off at a tem­perature below -20°C and switches
on again when the temperature
rises.

In the event of damage to the sen­sor or capillary tube and on reach­ing a temperature of about 220°C,
the filling medium is drained and
the combination controller switch­es off towards the safety side. The
combination controller is no longer
functional and must be replaced.

For replacement of the triple func­tion combination controller, the
following information must also
be observed:

The three functions of the
combination controller:

1. Fan controller (TR)
Controls the fan on and off
function. The switching point
can be set via the „TR control
lever“.

Set value about 40°C

2. Temperature monitor for the
burner (TW)

The temperature monitor limits
the air outlet temperature. The
switching point can be set via the
„TW control lever“.
Set value about 80 – 85°C

ATTENTION

To prevent the operating tem­perature being exceeded again,
the operating conditions of the
heater must be checked prior
to resetting/releasing the STB.

3. Safety temperature limiter (STB)
The STB controls the tempera­ture monitor.

Switching point permanently
set to 100°C.

A restarting lockout prevents
the burner from being restarted.
The reset button (RESET) must
be actuated manually from
outside with the housing cover
closed.

NOTE

When replacing the triple
function combination control­ler, only a REMKO original
replacement must be used!

ATTENTION

safety devices must not be
overridden or blocked during
heater operation.

■

The capillary tubes must not

be damaged or bent during
installation.

■

Any bending must take place

only on the capillary tube and
not on the sensor.

■

To ensure that the heater func-

tions reliably, the sensors must
always lie freely in the hot air
stream.

■

The sensors must always be

free of dust and dirt.

■

Capillary tubes and sensors

must not be damaged in any
way.

■

The sensors must not have

contact with the combustion

Installation instructions

Installation of the heaters must
generally take place in compliance
with the directives of the buil­ding regulations (LBO) and the
Ordinance on Firing Installations
(FeuVO) of the respective federal
state.

The First Ordinance on the imple­mentation of the Federal Immissi­on Control Act (1st BImSchG) and
the subsequently issued statutory
requirements of the Ordinance
on Small Firing Installations (1st
BImSchV) must also be taken into
account.

Hot air heaters in particular are ex­cluded in some respects however.

NOTE

Only type tested hot air heat­ers with forced-air oil burners
(complying with DIN EN 267)
or gas burners (complying with
DIN EN 676) must be used.

NOTE

Where delivery from the fac­tory takes place with an oil or
gas burner, separate operating
instructions for the burner are
enclosed.

ATTENTION

The heaters must be in­stalled and mounted so that
they are easily accessible for
monitoring,repair and mainte­nance.

ATTENTION

Low or excess pressure in the
installation location must be
avoided as this can result in
combustion problems.

Selection of site of
installation

The following must be observed
when selecting the site of
installation:

1. Fire protection and operational
hazards.

2. Function:
Room heating free blowing or
with duct system.

Observe pressure conditions at
site of installation .

3. Operational requirements:
Heat requirements, air volume
flow, air circulation and out­side air operation, humidity, air
distribution, room temperature,
space requirement.

4. Option for connection to a
chimney system.

Oil and gas-fired hot air heaters
(also with a nominal heat output
above 50 kW) may generally be
installed outside heating rooms in
compliance with the Ordinance on
Firing Installations (FeuVo).

The guidelines of the building su­pervisory authority for the „instal­lation of heat generating systems“
must be observed.

Locations in which flammable sub­stances or mixtures are processed,
stored or produced in quantities
liable to be hazardous in the event
of ignition may be subject to ex­ceptions if it is ensured by suitable
measures that the substances or
mixtures cannot ignite due to the
heat generating system.

Combustion air supply

A sufficient supply of combustion
air must generally be ensured by
the respective requirements of the
building supervisory authority.

Extracts from M-FeuVO (Speci­men Firing Ordinance) (may vary
between federal states).

(1) For non-roomsealed heating

appliances with a total nominal
heat output of up to 35 kW,
the combustion air supply is
deemed verified if the heating
appliances are installed in a
room with:

1. Minimum one door leading
to the outside or one window
that can be opened (rooms
leading outdoors) and having
a cubic capacity of minimum 4
m3 per kW total nominal heat
output.

2. An opening leading to the
outside with an internal cross­section of minimum 150 cm2
or two opening each 75 cm2
or pipes leading to the outside
having cross-sections equiva­lent to the flow.

(2) For non-roomsealed heating

appliances with a total nomi­nal heat output of more than
35 kW and not more than 50
kW, the combustion air supply
is deemed as verified if the
heating appliances are installed
in rooms that comply with the
requirements specified in Sec­tion 1 No. 2.

(3) For non-roomsealed heating

appliances with a total nominal
heat output of more than 50
kW, the combustion air supply
is deemed as verified

if the appliances are installed in
rooms that have an opening or
pipe leading to the outside.
The cross-section of the opening
must be minimum 150 cm2 and
2 cm2 more for each kW nominal
heat output above 50 kW nominal
heat output.
The pipes must be dimensioned
equivalent to the flow.
The necessary cross-section may
be divided into maximum two
openings or pipes.

(4) Combustion air openings and

pipes must not be sealed or
closed unless it is ensured by
separate safety devices that the
heating appliance can only be
operated when the closure is
open. The necessary cross-sec­tion must not be constricted by
the closure or grille.

(5) A sufficient combustion air

supply can be verified for non­roomsealed heating appliances
using a different method than
that specified in paragraphs 1
to 3.
For example by:
A continuous pipe of sufficient
cross-section connected to the
burner or its burner housing
leading to the outside. This
cross-section must be adapted
to the available suction capac­ity and the pipe resistances
(including air inlet grille) so that
perfect combustion is ensured.

Installation

■

The heaters must only be

installed and operated in rooms
if they are supplied with suf­ficient air volume for combus­tion and the exhaust fumes are
discharged to the outside via a
suitable chimney system

■

Non-roomsealed heating appli-

ances may be installed in rooms
or buildings from which air is
extracted with the aid of fans or
ventilation systems, etc., only if:

1. Simultaneous operation of
the heating appliances and air
suction system(s) is prevented
by means of safety devices.

2. The chimney duct is moni­tored by means of special safety
devices.

3. The exhaust fumes of the
heating appliances are filtered
via the air suction system(s).

4. It is ensured by the type of
construction or dimensioning of
the system that no dangerous
low-pressure can occur.

■

The heaters must be installed

on sturdy, flame retardant sur­faces and outside traffic zones,
e.g. also the operating areas of
cranes.

■

The heaters must be installed

and operated in a manner that
excludes any risk to persons
through radiated heat and the
risk of fire.

■

The heaters must be installed

and mounted so that they are
easily accessible for repair and
maintenance.

■

Operating elements whose

improper operation can result
in dangerous operating condi­tions must be protected against
unauthorised use if they are
generally accessible.

■

with the standard combustion
chamber is not recommended.
During installation of the
mixed-air flaps (accessories),
these must be connected work­ing in opposite directions.
The supplied fresh air volume
should not exceed 30%.

■

The heaters must not be in-

stalled and operated in rooms
and locations subject to fire and
explosion.

NOTE

The heaters are suitable for the
use of inlet and outlet sided
accessories.

ATTENTION

Standard type heaters are not
suitable for exclusive use as
ventilation units.

■

The heaters must be installed

so that they do not consti­tute a hazard or unreasonable
nuisance, e.g. through shocks,
vibrations or noise.

9

Floor mounting

The heaters must be installed on
stable, flame retardant surfaces
and outside traffic zones, e.g. the
operating areas of cranes.

For the protection of the heaters
against damage in commercial
locations, for unhindered mainte­nance and repair of the heater and
burner as well as unhindered air
suction and blowing, a protection
zone at a distance of 1 m around
the heating appliance must be kept
free.

This protection zone must be
marked by a sign with the follow­ing inscription:

Protection zone

Keep free at a distance of

1 m

A permanent barrier for frequently
accessed areas is recommended.

Wall mounting

The wall to be used for mounting
purposes must be of flame retard­ant materials. The loading bear­ing capacity of the wall must be
verified (reinforcements must be
provided if necessary).

The brackets must be firmly fas­tened to the wall and the heaters
securely fixed to these.

Sufficient free space for main­tenance of the heat exchanger,
burner, fan and chimney system
must be provided.

■

Operating devices for the

heater and fuel supply must
be able to be operated from
ground level.

■

Where auxiliary equipment is

required for monitoring, main­tenance and repair, this must be
provided by the operator.

Suspended heater installation

The heaters must only be attached
to constructions designed to take
the weight or to ceilings of flame
retardant materials with sufficient
load bearing capacity.

Attachment must take place using
suitable anchors to be securely
attached to the heater.

The requirements specified in the
Section „Wall mounting“ must be
observed.

Room heating

Hot air heaters must only be oper­ated in closed rooms and halls via
a room thermostat.

Fuel supply

The fuel supply must be installed in
compliance with the requirements
of DIN 4755 for oil-fired hot air
heaters, DIN 4756 and DVGW
worksheet G 600 for gas-fired hot
air heaters and TRF for liquid gas.

It must be ensured for fuel oil
piping in particular that the cross­section of the piping is of sufficient
size.
The suction height, total pipe
resistances and increased viscosity
at low temperatures must be taken
into account in dimensioning of
the system.
Suitable, separate oil supply units
must be provided if necessary.
The pipes must be installed so
that they are easy to vent and
protected against corrosion and

mechanical damage.

ATTENTION

The measured pressure in the
suction pipe should not exceed
minus 0.3 bar; it can be maxi­mum minus 0.4 bar.

Electrical installation

ATTENTION

Electrical heater connection
must be carried out by au­thorised specialists as defined
in DIN EN 60335-1 and VDE

0116.

It must be ensured that an im­permissible undervoltage due to
intermittent system overload is not
possible.

The cables used for connection
of the heaters must have a cross­section of sufficient size in order
to avoid any impermissible voltage
drop when the fans start.

For connection of the 400V
type heaters, the correct phase
sequence of the rotating field
(clockwise) must be ensured.
Incorrect connection can result in
an incorrect direction of rotation of
the fan.

An emergency switch must be pro­vided at an easily accessible point
in the installation room for heaters
with a nominal heat output from
50 kW.

ATTENTION

All switches, if generally ac­cessible, must be protected

an expert for reliable operation as
necessary, however at least once a
year.

The operator is obliged to have
the heating appliances inspected
at least once a year for correct
operation, reliability, efficiency and
maintenance of emission limits by
a representative of the manufac­turer or other authorised specialist.
The measurement of combustion
values must take place in accord­ance with the statutory require­ments of the Federal Immission
Control Act (BImSchV).

Where faults are discovered,
the operator must be notified
that he is obliged to arrange for
immediate repair or replacement of
components.

The following applies:
Repairs to limiting devices, auto­matic actuators, flame monitoring
devices and other safety devices
must only be carried out by the
respective manufacturer or his
representative on the individual
device.

NOTE

It is recommended to conclude
a maintenance contract with
an authorised specialist com­pany for regular maintenance
and cleaning.

The heaters must be connected to
a suitable and approved chimney
system.

NOTE

The erection of the chimney
system requires permission in
any event.

Chimney systems are structural
systems in or on buildings which
are solely intended for discharging
exhaust fumes from heat generat­ing systems safely via the roof.

The following are of particular
importance for the planning and
erection of chimney systems:

■

The respective Ordinance on

Firing Installations (FeuVo),

■

The respective building regula-

tions (LBO).

■

DIN 18160, part 1, design and

performance.

■

DIN 4705, part 1, calculation of

firing installations.

■

Technical directives for gas

installation DVGW-TRGI 1996

For the design and installation of
chimney systems, the following
must be observed:

■

Installation and erection of the

chimney system must be carried
out professionally and in com­pliance with the respectively
applicable regulations.

■

The dimensions of the chimney

pipe must correspond to the
power of the unit, structural
conditions and specific require­ments.

■

Chimney systems must be di-

mensioned according to internal
cross-section and height so that
the exhaust fumes are dischar­ged to the outside in all normal
operating conditions and no
dangerous positive pressure can
occur with respect to rooms

■

The outlets of chimney systems

must rise minimum 40 cm abo­ve the ridge or be minimum 1
m away from the roof.

■

Where dynamic pressures are to

be expected, e.g. due to down
winds or from neighbouring
buildings, the chimney coping
must be designed appropriately.

■

In the case of roof or wall

openings, the chimney system
must be lead through tubular
sleeve or shaft to enable free
expansion of the chimney pipe
on heating.

■

Connection of the heating ap-

pliance must take place tightly
sealed and protected against
accidental loosening by means
of rivet or screw.

■

Horizontal chimneys should

preferably be kept as short as
possible.

■

A reclosable measuring open-

ing must be provided in the
chimney pipe downstream of
the appliance connection at a
distance of 2 x D ( Ø).

ATTENTION

It must be ensured that no
back pressure occurs due to an
incorrectly installed chimney
duct.

complying with DIN EN 267 or
forced-air gas burners (comp­lying with DIN EN 676) may be
used.

■

Power limitation for single-

stage burner operation (up to
70 kW) is not required for hot
air heaters.

Fuel oil connection

A sufficient and correct fuel supply
must be ensured.

■

The suction pipe must be provi-

ded with a foot valve in the fuel
oil tank.

■

Free flowing fuel oil must be

available in sufficient quantity
also at low outside tempera­tures.
Paraffin formation can occur
already from about 5°C depen­ding on the fuel oil quality.

Appropriate measures must be
taken to prevent this occurring!

NOTE

Prior to initial use, the gas
supply pipe must be cleaned
thoroughly and checked for
leaks!

ATTENTION

Installation, adjustment and
maintenance of the gas supply
must only be carried out by
specialists authorised by GVU!

Commissioning

Commissioning of fan motor

Testing drive

1. The mounting screws of the
complete drive must be checked
for tightness.

2. The initial tension of the drive
belt(s) must be checked.

ATTENTION

The fan must be checked for
correct direction of rotation.

Current consumption
measurement

1. To prevent incorrect measure­ments, the grilles in the air
duct or air outlet hood must be
opened.
All supplied air inlet and metal
panels must be mounted on the
appliance.

2. Check the system voltage for
correctness.

3. Carry out the necessary meas­urements and adjust settings as
required.

NOTE

In order to exclude measure­ment errors, each phase should
be measured separately.

■

Direct starting

The measured rated current
must not exceed the value
shown on the motor rating
plate.

Check the thermal overcurrent
relay appropriate to the rated
current of the drive motor and
adjust if necessary.

■ Y / Δ - starting
The measured rated current
must not exceed the value
shown on the motor rating
plate.

NOTE

The rated current of the drive
motor must be multiplied by
the factor 0.58.
Check the setting of the
thermal overcurrent relay with
respect to the calculated value
and correct if necessary.

Thermal overcurrent relay

The function of the overcurrent
relay or its setting can be checked
by removing a fuse.
A correctly operating relay must
operate after about 30 seconds.

ATTENTION

The thermal overcurrent relay
must only be operated in a
manual mode.
Under no circumstances must
the relay switch on again
automatically

Excessive current
consumption

If the fan motor should consume
excessive current despite correct
electrical connection and sufficient
system voltage, under no circum­stances must the overcurrent relay
be set higher or overridden.

In this case, the air-sided resist­ances (inlet/outlet side) must be
checked for correct dimensioning.
Suitable measures must be pro­vided for this purpose.

Commissioning

Commissioning of the unit and the
forced-air burner must take place
by the manufacturer or a specialist
authorised by the same. All regu­lating, control and safety devices
must be checked for their proper
functioning and correct adjust­ment.

■

The commissioning of oil and

gas-fired heating appliances
must always be carried out by
authorised specialists.

■

All bolts and nuts of the fan

and burner mounts must be
checked for tightness.

■

All air outlet grilles must

be opened and adjusted if
necessary.

■

The settings and function of

the triple function combination
controller must be checked.

■

Switch on the local main switch

or fuses.

■

Set the room thermostat

higher than the existing room
temperature.

■

Open the fuel supply and

switch the switch to the „Heat“
position.

Factory supplied oil burners
start with a delay due to the
standard oil preheating (up to
VRS 50)!

■

The fuel oil or gas flow rate

must be adjusted appropriate to
the heat load of the appliance.

See appliance rating plate!

15

■

T he burner must be set to the

values specified by the manu­facturer, however at least to the
values specified by the Federal
Immission Control Act.

Heating

The appliances operate fully auto­matically depending on the room
temperature.

Ventilate

1. Set the switch on the control
box to the „II“ or „Ventilate“
position.

■

A measuring report must be

prepared and handed to the
operator for safe keeping.

■

The operator must familiarise

himself with the operation of
the system.

■

The responsible authori-

ties must be provided with a
declaration from the specialist
company and certificate of the
installer.

Information on corrosion in
heat exchangers.

■

It must be ensured that the

exhaust fume temperature
difference of 180 Kelvin is not
reached.

This prevents the risk of cool­ing below the dew point and
related corrosion in the heat
exchanger to a large extent.

NOTE

If the heaters are not set to
their nominal heat load (see
rating plate) or are dimensi­oned too large for the neces­sary heat requirement, the bur­ners operate in an intermittent
mode.

As the necessary operating
temperature of the heat ex­changer cannot be reached in
intermittent operation, increa­sed condensation unavoidably
occurs with the consequence
of higher corrosion in the heat
exchanger.

1. Switch on the local main switch
or fuse(s).

2. Open the fuel supply.

3. Set the desired temperature on
the room thermostat.

3. Set the switch on the control
box to the „I“ or „Heat“
position.

230V type

400V type

It should be noted that the forced­air burner starts immediately on
heat demand (except VRS 25 and

50), however the supply air fan

initially starts automatically when
the set temperature is reached.

This prevents cold air from being
blown out.

In this switch position, the supply
air fan runs continuously.
The appliances can be used for air
circulation or ventilation purposes.
Thermostatic control is not
possible.

Switching off

Set the switch on the control box
to the „0“ position.

The supply air fan continues to
operate to cool the heat exchanger
and can start several times up to
final switch off.

ATTENTION

The heater must never be
disconnected from the mains
supply via the main or emer­gency switch before the cooling
down phase has ended (except
in emergency situations).

For extended periods of
non-use, the units
should be disconnected
from the power supply
and the fuel supply
shut-off.

Cleaning and maintenance

The operator is obliged to have the
system inspected at least once a
year for correct operation, reli-reli­ability, efficiency and maintenance
of emission limits by an authorised
specialist

ATTENTION

Prior to carrying out main­tenance or repairs, the unit
must be disconnected from the
mains supply.

ATTENTION

It does not suffice to switch off
the unit only via the switch!

■

The complete heating appliance

including heat exchanger, com­bustion chamber and forced­air burner must be cleaned to
remove adhering dust and dirt.

■

The combustion residues in the

combustion chamber and heat
exchanger must be removed by
suitable means.

■

The limitation of exhaust fume

losses must be maintained in
accordance with § 1, paragraph
1 of the Ordinance on Small
Firing Installations (1st BIm­SchV).

■

The verification of work carried

out by authorised specialists in
addition to the usual reports
must be provided in any event.

ATTENTION

Adjustment and maintenance
of the forced-air burner must
only be carried out by autho­rised specialists.

NOTE

It is recommended to conclude
a maintenance contract with
an authorised specialist com­pany for regular maintenance
and cleaning.

ATTENTION

Soot deposits

Small soot deposits on the heat
transfer surfaces of the combus-combus­tion chamber and heat exchanger
degrade heat emission.
This reduces the overall efficiency
of the system.

A soot layer of 1 mm thickness
causes an exhaust fume tempera­ture increase of about 50 K
(see diagram).

This shows that an optimal burner
setting and regular maintenance
are essential for maintaining the
efficiency and emission limits.

■

■

■

The V-belt tension and motor

mount must be checked at
regular intervals.

Wearing parts such as flue gas

brakes, seals, oil filter element
and oil nozzles, etc. must be
checked and replaced if neces­sary.

The maintenance instructions of

the separate forced-air burner
must be observed in any event.

If the operational cleaning and
burner adjustment intervals are
not maintained, the warranty
will be invalidated!

17

Troubleshooting

The heater does not start

■

Check the local mains supply

connection.

■

Check the fuses in the control

box.
(Only 400V three-phase type)

■

Set the switch to the „I“ or

Heat position.

■

Check that the „Burner“ indi-

cator light on the control box
(only 400V type) is illuminated.

■

Check the thermostat connec-

tion or room thermostat cable.

■

Check the room thermostat

setting.
The temperature set must be
higher than the existing room
temperature.

■

Check whether the safety tem-

perature limiter (STB) may have
operated.

Possible causes:

■

The heaters could not cool

down because the power supply
was interrupted.
A brief interruption of the pow­er supply can also cause the STB
to operate.

■

The temperature of the air
being blown out is too high due
to incorrectly installed chimney
ducts or adjusted grilles.

■

The fan was overloaded and the

thermal overcurrent relay of the
400V type heater or thermal
contacts in the fan motor of
the 230V type heater have
operated.

■

The V-belt for the fan drive is

loose or faulty.

■

The air inlet or outlet is not free.

■

Check the temperature control

thermostat (TR) for correct
functioning and adjustment.

The burner does not start

■

Check the oil filter for clogging.

Replace clogged filter(s).

■

Check that the shut-off valve

on the oil filter is open.

■

Check the fuel tank for suffi -or suffi-

cient fuel.

■

Check the fuel and filter for

paraffin separation.

Paraffin separation can occur
already below 5°C.

■

Check the oil hoses for damage

and leaks.

Air may also be sucked in!

■

Check the safety temperature

limiter (STB).

■

Check the temperature monitor

(TW).

ATTENTION

Prior to carrying out main­tenance or repairs, the unit
must be disconnected from the
mains supply.

■

Check the temperature monitor

(TW) for correct functioning
and adjustment.

ATTENTION

Prior to releasing a safety
device, the cause of operation
must be located and
eliminated.

■

Check the capillary tubes and

sensors of the triple function
combination controller for dam­age and correct positioning of
the sensors.

■

Check whether the fault indi-

cator light of the burner relay is
illuminated.

The supply air fan does not
start

Set the switch to the „II“ or „Ven­tilate“ position.

The supply air fan should now
start!

NOTE

If no result is achieved after
carrying out all functional
checks, an authorised service
station should be contacted.

ATTENTION

■

If the fault indicator light is

illuminated, release the burner
relay by pressing the fault
button.

The fault indicator light
extinguishes and the burner
attempts to start!

■

With VRS 25 and 50 heating

appliances, the burner starts
with a delay due to the oil pre­heating
(only factory supplied burners)

ATTENTION

If the burner should shutdown
after starting due to a fault, a
release attempt can only take
place after five minutes.

No further release attempts
should be made in any event
due to a risk of deflagration.
