NOTE

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

NOTE

The heaters are not suitable for domestic heating or similar.

Unit description

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.

Page 5

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.

Heater applications

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

Mode of operation

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.

ATTENTION

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.

ATTENTION

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.

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:

Fire protection and operational

hazards.

Function:

Room heating free blowing or with duct system.

Observe pressure conditions at site of installation .

Operational requirements:

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

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

per kW total nominal heat

output.

2. An opening leading to the outside with an internal crosssection of minimum 150 cm or two opening each 75 cm 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

Page 9

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 cm

2 cm

more for each kW nominal

and

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

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 50E)!

■

The fuel oil or gas ﬂow rate

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

See appliance rating plate!

Page 16

REMKO VRS

■

The burner must be set to the

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

■

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.

Heating

The appliances operate fully automatically depending on the room temperature.

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

2. Open the fuel supply.

3. Set the desired temperature on the room thermostat.

4. 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.

Ventilate

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

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.

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!
