Description of Device

The units are mobile, warm air heaters with heat-

exchangers and an exhaust connection for commercial

use.

The unit is fired directly with heating oil or diesel. It is

designed for fully-automatic, universal and reliable use.

The units are only operated with separate forced-air

burners.

The unit is equipped with a quiet, high-performance ax-

ial ventilator requiring little maintenance, a connection

cable with plug and a room thermostat socket.

The standard units with forced-air burners supplied di-

rectly from the factory are equipped with a fitting for an

oil reservoir and an electric oil preheater.

Up to CLK 70: preheater in nozzle stock.

CLK 120 and higher: REMKO multifilex oil preheater.

The unit complies with the basic safety and health re-

quirements of the relevant EU regulations and is reliable

and simple to operate.

Areas of application

The units are mobile, warm air heaters that supply instan-

taneous heat. They are only used for commercial pur-

poses.

The unit can be used e.g. in the following areas:

− for drying new buildings

− for point heating of outdoor workplaces

− for point heating of workplaces in open, non fire-

hazard fabrication rooms and halls

− for heating closed and open rooms, on a permanent

or temporary basis

− to de-ice machines, vehicles and non-flammable

storage goods

− to maintain the temperature of components suscepti-

ble to frost as well as greenhouses

Device functionality

If the unit is switched to heating mode, the forced-air

burner starts automatically. In fully-automatic heating

mode, the forced-air burner starts only when the room

thermostats determined that heat is necessary.

After the burner has run for a short time, the temperature

control thermostat “TR” (rated temperature 35 to 40 °C)

automatically switches the air supply fan on. Warm air is

blown out.

When the room thermostat is in operation, the process

above is automatically repeated depending on the

amount of heat required

The temperature monitor “TW” (rated temperature 80 to

85 °C) monitors the internal temperature of the unit.

After the device is switched off with the operating switch

or the room thermostat, the air supply fan runs for a cer-

tain amount of time to cool the combustion chamber with

heat-exchanger and then switches off. This process can

be repeated several times.

Never interrupt the power supply (except in emer-

gency situations) before the unit has reached the

end of the cool-down phase.

Before doing any maintenance or repair work,

make sure to unplug the unit from the power sup-

ply.

Monitoring operation of device

All functions of the unit are fully automatic and moni-

tored for safety by the safety facility and the automatic

burner relay (part of the forced-air burner).

If the flame burns irregularly or goes out, the unit is

switched off by the automatic burner relay. The control

lamp on the control panel and the malfunction lamp of

the automatic burner relay light up.

Before the unit can be restarted, the automatic burner relay

must be released by pressing the external reset button on

the operating panel or the reset button on the automatic

burner relay.

The fan control (TR) regulates operation of the fan. The

temperature monitor (TW) limits or regulates the tem-

perature of the unit in heating mode.

The safety temperature limiter (STB) interrupts heating

mode when extreme overheating occurs or if the tem-

perature monitor (TW) stops working or is defective.

The STB can only be manually released after the unit

has cooled down.

Before the STB is released to begin operation

again, the reason the STB was activated must be

determined.

Installation Requirements

The heaters may only be installed in compliance with

the relevant regulations, in particular, regulations gov-

erning the installation and operation of fireplaces and

furnaces.

Any national/regional emission control laws or regula-

tions must also be observed.

à Avoid under- or overpressure in the room where the

unit is installed, as this would result in combustion

troubles.

à Make absolutely sure that the opening for air intake

and output is adjusted to the fan power (see model

plate).

If this is not possible, the burner has to be equipped

with a separate air supply device to ensure optimum

combustion.

Installation in closed, well aerated rooms without

connection to a chimney

à The units may only be operated when the minimum

amount of air required for combustion is supplied.

à A safe exhaustion of the waste gases is to be en-

sured to exclude inadmissible pollution.

- Fresh air is supplied from below.

- Waste gases are expelled upwards.

Outside installation

à Operation of the unit may not have any harmful ef-

fects or cause any unreasonable problems.

à The unit operator must ensure that unauthorised per-

sons are prevented from manipulating the unit or its

power supply.

à Because rain and snow can be sucked in by the air

supply fan, a suitable protective covering should be

used.

Heating Rooms

à Warm air generators may only be operated with a

room thermostat when heating rooms.

Accessories.

à Make sure that there is enough fresh air to ensure

optimum combustion.

Safety zones

à To ensure safe operation and guarantee unhindered

access to the unit for maintenance work, a safety

zone of 1.5 m should be maintained around the unit.

à Floors and ceilings must be fire-resistant.

Electrical Connection

à The units are operated with 400 V / 3~N / 50 Hz.

à The unit must be connected to the power source at a

special terminal equipped with a switch to protect

against faulty currents.

à Extension cable may only be laid by authorised elec-

tricians based on the capacity of a unit, the length of

the cable and in accordance with local requirements.

à All extension cable may only be used once they have

been unrolled.

While the unit is in operation, the safety features

may not be bypassed or blocked!

Information on the Safety Device

The device is equipped with a sensor monitoring feature

and is resistant to cool down to temperatures of -20°C;

below -20°C the device switches off; when the tempera-

ture rises above this temperature, it switches on again.

When the sensor or capillary tube is damaged, or when

an excess temperature of approximately 220°C is

reached, the liquid contained in the thermostat is emp-

tied and the device switches off for safety purposes.

The device is no longer operable and must be replaced

If it is necessary to replace the STB, only the original

REMKO part may be used.

à Make sure to install and mounting the device care-

fully.

à Do not bend the capillary tubes near to solder points.

à When installing the capillary tubes, be careful not to

damage or bend them too sharply.

à The sensors may only be mounted in the mounting

brackets supplied by the manufacturer.

à The sensors must always be free from dust and dirt.

Safety Device

The device has 3 safety functions:

à Fan control (TR)

à Temperature monitor (TW)

à Safety temperature limiter (STB)

Fan control (TR)

The fan control switches the circulating air fan off and

on. The point at which the device is switched on or off is

set in the control box via the temperature control ther-

mostat “Scale 21 – 60”.

Rated value approx. 35 to 40°C.

Temperature Monitor (TW)

When the unit is in heating mode, the temperature

monitor limits both the temperature of the unit and the

air being blown out. The switching point is set via the

temperature control thermostat “Scale 34 – 110” in the

control box.

Rated value approx. 80 to 85°C.

Safety Temperature Limiter (STB)

The STB controls the temperature monitor. The switch-

ing point is fixed. The burner is prevented from being re-

started if the STB is activated.

After the cover next to the control panel is removed, the

reset button must be pressed from the outside.

After the STB has been reset, the cover must be replaced.

Before a STB reset, check the operating conditions

to ensure that the STB temperature is not ex-

ceeded again.

à The unit generally operates properly when the waste

gas pipes have been laid at an incline and assem-

bled with vertical end pipes.

à The waste gas pipes must reach at least beyond the

gutters but preferably above the top of the roof to

prevent counter pressure caused by weather condi-

tions (e.g. wind).

à All waste gas pipe components must be securely

fastened. They may not be smaller in diameter than

the waste gas connection.

à A minimum distance of 0.6 m must be maintained

from flammable objects.

à Waste gas components incl. fasteners can be pur-

chased as accessories.

Waste Gas Pipes

When the units are operated outside or in open rooms

you do not need a waste gas pipe. However, we recom-

mend using a waste gas pipe 1 m long (see example 2)

with a rain cover on top to prevent the penetration of

rainwater and dirt.

If the units are used as room heaters, it is necessary to

route the waste gases to the outside.

Make absolutely sure that counter pressure is not

created by improperly laid waste gas pipes.

Important Information.

To prevent damage to the combustion chamber caused

by moisture build-up (condensation) (see example 3),

make sure that the waste gas pipes have a properly in-

stalled condensation trap (see example 1).

When using an waste gas connection, the burner

must be adjusted accordingly.

à Install the unit in a stable position.

à Make sure that air is supplied for combustion.

à Make sure that the air can be sucked in and be ex-

hausted freely.

à Avoid overpressure and underpressure in the room

where the unit has been installed.

à Make sure that enough fuel is supplied.

à Please note: the multifilex oil preheater will only func-

tion properly if voltage is supplied to the unit for a

longer time prior to initial operation.

à Use only clean heating oil or diesel.

Do not use bio diesel.

Additional information

The waste gas values of the oil-burner are to be

checked and properly adjusted by authorised personnel

to ensure compliance with local requirements.

Paraffin accumulation at low outside temperatures

A sufficient amount of heating oil must be able to flow

freely even when temperatures are low.

à Paraffin can accumulate even at temperatures below

5 °C.

à Appropriate measures must be taken to prevent this.

Use winterised heating oil or winter diesel.

Connection to the power supply

The units are operated with 400 V / 3~N / 50 Hz.

à The unit is connected to the power supply by an at-

tached power cable with a grounded contact plug.

à Extension cables may only be laid by authorised

electricians based on the capacity of a unit, the

length of the cable and in accordance with the in-

tended use.

The unit must be connected to the power supply at

a special terminal equipped with a switch to pro-

tect against faulty currents.

Extension cables may only be used once they are

unrolled.

Flexible fuel tubes must be protected from being

damaged, e.g. from forklifts, animals, etc.

Starting

Only those persons who have been trained in operation

of the unit may be responsible for operating and moni-

toring it.

Hot air distribution

The units are equipped with a high-performance axial

fan. This fan has been designed to transport the hot air

directly and effectively.

It is preferable to distribute air by means of pipes or

special hot air hoses. Warm air may only be distributed

in accordance with the fan capacity of the unit in opera-

tion.

Please follow these instructions when attaching warm

air hoses:

à Use only warm air hoses (accessories) approved by

our company.

à Make sure that the hoses and/or pipes are securely

attached to the unit’s air outlet connection.

à To prevent heat from building up, the pipes and

hoses may not have sharp kinks and bends.

à Counter pressure may not be allowed to build up

when using hoses to heat closed rooms.

à If suction temperatures increase or if there is resis-

tance on the air output opening, the forced-air burner

can be switched off at short notice by the tempera-

ture monitor (TW) in heating mode.

When the temperature falls, the burner restarts auto-

matically.

à If the intervals are too short, the length of the warm

air hoses should be checked.

Avoid starting the burner in frequent cycles (under

5 min.).

Unit Shut Down

Important information about the unit’s cool-down

phase

The air supply fan continues running to cool down the

combustion chamber and then stops at a later time.

The fan can run several times before the unit is finally

switched off.

1. Set the operating switch to “0”

OFF.

2. Shut off the fuel supply.

Never interrupt (except in emergency situations)

the power supply until the cool-down phase is

completely finished.

was activated.

You must remove the protective cover next to the

control panel.

7. Before resetting the STB, it is absolutely necessary

to determine the reason it was activated and take

appropriate measures.

The following are possible reasons:

− Unit could not cool down because the power sup-

ply was interrupted.

− Temperature of air being blown out is too high be-

cause hoses are not directing air properly.

− Air intakes and outlets are blocked.

8. Check whether the “burner malfunction” control

lamp on the control panel is illuminated.

If so, release the automatic burner relay by pressing

the reset button.

9. Set operating switch to “II”

If the fan now starts running, look for the malfunc-

tion in the burner.

Initial Operation of the

Forced – Air Burner

Preparation

After loosening the 4 housing bolts, remove the mount-

ing base plate of the housing so that it is suspended to

the side.

There are 6 housing bolts to disassemble for the SL 44

model (look for the arrows).

The operating parts are immediately accessible and can

now be serviced.

To service, insert or replace the nozzle, the base plate

must be suspended horizontally by hooks.

Proceed as follows:

1. Hold base plate horizontally.

2. Push right-hand mounting laterally into hook device.

3. Hook left-hand side into the lug.

Setting ignition electrode and device

All measurements are approx. values in mm. The opti-

mum setting must be adjusted to local and structural re-

quirements.

size \ dimension A B C D

SLV 11 und 33 2 - 4 4 - 6 7 2,5

SL 44 13 - 15 12 - 14 5 3

Required nozzle sizes

Selecting the required oil nozzle depends on the pump

pressure and the unit capacity.

You may only use an oil nozzle that is suitable for the

shape of the respective burner chamber with a corre-

sponding spray angle, cone properties and throughput.

You can find the required oil nozzle sizes under Techni-

cal Data.

Air slide plate

The adjustable air slide plate is used to adjust the

burner pressure to the amount of resistance in the com-

bustion chamber and the chimney draught without hav-

ing to make changes to the original cross-section.

1. Loosen socket screw.

2. Turn air slide plate to desired setting.

Pay attention to the arrows.

Turn to “min” = reduced burner pressure

Turn to “max” = increased burner pressure

Base plate

After changing the nozzle and setting the air slide plate,

reassemble the base plate in the reverse order.

Secondary air setting

(Setting the nozzle stock)

Proceed as follows to preset the secondary air:

Use the adjusting screw 1 to adjust the nozzle 2 to the

value you want.

Counter clockwise (-) = lower scale values

increased pressure behind the air flow plate

lower performance range

Clockwise (+) = higher scale values

lower pressure behind the air flow plate

upper performance range.

SLV 11 und SLV 33

SL 44

Counter clockwise (+) = higher scale values

reduced pressure behind the air flow plate

upper performance range

Counter clockwise (-) = lower scale values

increased pressure behind the air flow plate

lower performance range

Adjusting the air flap

Proceed as follows to adjust the air flap:

1. Loosen the knurled nut 4.

2. Rotate the adjustment screw 3 accordingly.

3. Keep the following in mind:

Right rotation = less air

Left rotation = more air

4. After the adjustment is completed, retighten the ad-

justment screw with the knurled nut.

Additional Information

à If the air flap is completely open and the flame emits

smoke or flickers, use the secondary air setting to

lower the pressure behind the air flow plate.

à It might be necessary to open the air slide plate even

further.

Air flap

The adjustment screw 3 is used to set the required

quantity of air.

The air flap is opened or closed until the soot profile dis-

plays an oil-free colour “0 - 1”.

Setting the pump pressure

For initial burner operation and after each time the

burner is serviced, the oil pressure must be adjusted

and/or checked.

Proceed as follows to adjust the pump pressure

1. Remove the stopper on the “P” measuring connec-

tion.

2. Mount the oil manometer.

3. Open all shut-off fittings in the oil supply.

4. Switch the burner on.

5. Set the required oil pressure in accordance with the

size of the nozzle and the unit performance.

6. Switch the burner off.

7. Disassemble the oil manometer.

8. Replace the stopper and its seal.

Important Information

The forced-air burner may only be put into operation by

trained personnel

à All specifications only serve as presets and must be

set or adjusted after the waste gas has been ana-

lysed.

à Exhaust emissions must be restricted in accordance

with the ordinance on small furnace systems.

Never operate the pump without fuel!
