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 chamber or other metal parts.
ATTENTION
Installation and assembly must be carried out carefully and professionally.

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.

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.
Direct suction of the outside air
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.

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.

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.

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
Cleaning the combustion chamber and heat exchanger
1. Disconnect the appliance from the mains supply.
ATTENTION
It does not suffice to switch off the unit only via the switch!
2. Shut off the fuel supply.
Remove the following
components:
1. The forced-air burner.
2. Burner plate with burner
flange.
3. Front lining plate(s).
4. One side lining plate (left or
right depending on structural conditions).
10. The combustion residues in the combustion chamber must be removed though the burner opening also using a suitable vacuum cleaner.
A special boiler cleaning set for the REMKO industrial vacuum cleaner is available as an accessory.
11. After cleaning, all parts must be carefully refitted in reverse order.
ATTENTION
The burner and all control units must be checked for per­fect functioning.
12. The correct assignment of the exchanger tubes and correct seating of all seals must be ensured.
Damaged or deformed seals must be replaced.
13. Burner maintenance must be carried out as specified in the separate operating instructions of the burner.
NOTE
The limitation of exhaust fume losses must be maintained in accordance with §11 of the Ordinance on Small Firing Installations (1st BImSchV).
5. The two front inspection
covers.
6. The side inspection cover.
7. Remove the flue gas brakes
from the heat exchanger
tubes and clean or replace if damaged.
The correct assignment of the exchanger tubes must be ensured!
8. Clean the heat exchanger
tubes with suitable cleaning agents to remove adhering combustion residues.

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.
NOTE
Safety devices must not be overridden or blocked during heater operation!
19
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.
230V type
400V type
If the fan does not start:
Check the local mains supply connection.
Check the fan and drive for
smooth operation.
Check the V-belt of the fan
drive.
Check the electrical cables at
the fan motor for damage.
Check the fan to ascertain
whether it was overloaded and if the thermal overcurrent relay of the 400V type heater or thermal contacts in the fan motor of the 230V type heater have operated.
Check the capacitor in the fan
of the 230V type heater.
Repairs to the electrical instal­lation and burner must only be carried out by authorised specialists for safety reasons.
ATTENTION
Adjustment and maintenance of the appliance and forced-air burner must only be carried out by authorised specialists!
