Description of the unit

Deﬁnition of the equipment

Pursuant to EU Directives, the equipment is deﬁned as:

"Gas fan-assisted air heater without ﬂow-operated safety device, equipped with a fan in front of the heat exchanger".

The equipment is a fullyautomatic, directly-lit, fan-assisted air heater for wall and ceiling installation. It can be fuelled with natural gas or liquid gas.

The equipment is used for continuous and temporary heating of open and closed spaces, e.g. in:

halls, workshops greenhouses, storage rooms, etc.

Classiﬁcation of the equipment

The equipment was classiﬁed by the European standardised regulations EN 437 and EN 1020 according to:

The gas category:

determination according to the type of gases with which they may be operated.

For Germany DE II2ELL3B/P

The gas type:

the burner can be operated with gases of the second family (natural gas - group H and L) and with gases of the third family (butane and propane).

The type of gas ﬁreplace:

differentiation according to the possibilities of the discharge of the combustion products or the supply of the combustion air.

(ambient-air-dependent/ independent)

Additional notes can be found in the chapter "Installation of the ﬂue gas evacuation and the combustion air supply".

Design of the equipment

The exterior cladding of the equipment is made from coated steel sheet, which guarantees durability. The outlet grid is found in the front section. In order to ensure an optimal distribution of warm air in the installation location, the horizontal ﬁns of the outlet grid can be manually adjusted. On the rear side of the equipment you will ﬁnd the fan(s) with protective grid, the connection nozzles for the removal of the exhaust and supply of the combustion air, the gas connection nozzles, the cable passages for the electrical lines as well as the plug connection for the mains connection. In the right-hand side section the necessary components for the control and safety are found behind the inspection door, including:

- the electrical circuitry with the cabling

- the control electronics

- the gas valve

- the modulating gas burner

In the interior of the equipment, directly in the circulation air ﬂow is the combustion chamber with heat exchanger. The combustion chamber is manufactured entirely from Inox stainless steel, grade AISI 430. For the purpose of higher resistance to corrosion from damp vapours, Inox stainless steel, grade AISI 441 is used for the heat exchanger. The special form and the large surface area of the combustion chamber and heat exchanger guarantee a high level of efﬁciency and long service life. The gas burner is likewise manufactured entirely from special, mechanically-processed stainless steel.

Function of the equipment

The modulating, gas fan-assisted air heater of the GPM series has been developed for the heating of industrial and commercial spaces. The electronic control of the equipment continuously regulates the heat output between minimum and high-output according to the actual heat requirement. With the pre-mix and modulation technology, efﬁciency of up to 94% can be achieved.

The nominal heat output of the REMKO GPM series lies between

11.8 and 71.5 kW.

The equipment consists primarily of the combustion chamber with heat exchanger and the fan(s). The ambient air is suctioned in by the fan(s) and efﬁciently channelled through the combustion chamber with heat exchanger. The combustion chamber is heated by the gas burner operation and releases its heat to the air ﬂowing past. The air heated in this manner is blown out of the front side of the equipment through an adjustable outlet grid. The operation of the equipment as intended is only possible with a connected control unit, e.g. ATR-6 (accessory).

NOTE

The units are not suitable for the heating of living spaces or the like.

Efﬁciency Cycle of operation

The advantages of the units lie in the modular mode of operation, meaning the heat output created and thus the gas ﬂow (consumption of fuel) are changed corresponding to the heat requirement. With a reduced heat requirement of the room, the fan-assisted heater consumes less fuel, whereby its efﬁciency is increased by up to 94%.

Intrinsic safety

The increase in efﬁciency with minimum output is achieved through the use of a modern air/ gas mixture technology and the simultaneous ﬂow rate regulation of combustion air and gas. This technology increases the safety of the equipment, because the gas valve feeds the fuel depending on the amount of air in accordance with its factory settings. Unlike atmospheric burners, the CO2 content remains the same through the entire operating range and allows an increase in efﬁciency with reduction of the heat output. With no combustion air, the valve does not release gas. With reduction of the combustion air, the gas valve automatically reduces the amount of gas and keeps the combustion parameters at an optimal level.

Burner operation

The heat requirement for starting the burner can be adjusted with the room temperature sensor NTC2 in the electronic temperature regulation ATR-6. In the cases of equipment both with and without electronic temperature regulation, the burner is only started if the contact 7-9 of the terminal block M1 is closed. At the beginning, while igniting, the control PCB starts the fan of the burners so that the combustion chamber is pre-ventilated for a pre-adjusted length of time. After the pre-ventilation, the control PCB releases the ﬂame monitoring unit ACF for ignition of the burner. Then the gas-solenoid valve EV1 and solenoid valve EVP, which supply the ignition gas burner, are then opened. In this way the ignition burner's ignition phase, which takes place through the ignition electrode, is started. The monitoring electrode, on the other hand, checks the successful ignition of the gas ﬂame.

If this operational condition is recognised, the control device opens the main gas valve EV2 for the supply of the actual burner. After a certain length of time, during which both burners (ignition burner and main burner) are simultaneously in operation, the control PCB switches off the electromagnetic valve EVP, whereupon the ignition burner extinguishes. The ﬂame monitoring for the control of the main burner likewise takes place through the monitoring electrode. The startup program switches on the burner with an average heat ﬂow rate, which is set to about 70%of the highest ﬂow rate. Approximately thirty seconds after the ignition, the burner starts with the modulation of the gas ﬂow rate and then achieves the gas ﬂow rate determined by the settings. During operation, the control PCB regulates the gas ﬂow rate of the burner proportional to the circulating air temperature, which is measured by the NTC1 sensor on the rear side of the unit.

Fans

The switching on of the fans is time-controlled by the control PCB, whereby the timing begins with the switching-on of the main burner. The delayed switching prevents cold air from being blown into the room. The pre-adjusted time delay may range from 0 to 255 seconds [Parameter C3]. If the value is set to zero, the startup of the fans takes place at the same time as the burner.

Switching off the unit

If there is not longer a heat requirement (room temperature above the adjusted target value), the control PCB switches off the burner. The burner fan runs for the secondary ventilation of the combustion chamber for a ﬁxed, pre-set time. This adjustment cannot be changed.

The fan(s) likewise run afterwards until the heat exchanger is cooled. The time delay may range from 0 to 255 seconds [Parameter C4].

ATTENTION

Do not adjust parameter C4 to values below a minimum running time of 90 seconds for the cooling of the combustion chamber.

The interruption of the current supply during burning operation is not permitted for the same reasons, because lack of a secondary ventilation of the heat exchanger can lead to the following problems:

■

Overheating of the unit with

the resulting expiration of the warranty

■

Tripping of the safety

thermostat and the manual reset associated with it

■

Damage to the fan of the

burner

If a new heat requirement should take place during the follow-up phase, the control PCB will wait for the fans to switch off and then proceed with a reset and begin a new cycle.

Safety thermostat(s)

For each fan on the units there is a safety thermostat (STB) with automatic deactivation and positive security; a release of the sensitive element triggers a safety shutdown. The thermostat is installed in the area of the heat exchanger in order to monitor the temperature at its output. The triggering of the thermostats causes the shutdown of the burner by means of the ﬂame monitoring unit until the disabling of the monitoring device. The disabling of the device caused by the triggering of the safety thermostat is displayed by fault F2.

Display of the LED

A green and red LED are installed on the front side of the unit. The illumination of the green LED means that the unit is connected to the mains. The illumination of the red LED indicates a malfunction of the unit.

When operating the unit with electronic temperature regulation ATR-6, the LED is continuously illuminated in the event of a malfunction. The error code is shown in the display.

The control PCB mounted in the units differentiates between 6 different faults:

F1 - Fault at the ﬂame monitoring

F3 - Malfunction by the burner

motor.

F4 - Malfunction by one of the

NTC sensors.

F6 - Malfunction of the control

PCB.

F8 - Flame monitoring sensor

defect.

The faults F1 and F2 are caused by safety devices and therefore are permanent: The fault persists when switching off and restarting the mains connection and can only be unlocked manually.

The faults F3, F6 and F8 must be unlocked manually by switching off and restarting the mains connection.

The fault F4, on the other hand, resets itself: after remedy of the cause of fault, the fault report ceases.

NOTE

Reset button

On the front of the unit a manually-actuated reset button is installed, which enables the unlocking of the unit after the faults F1, F2, F3 or F8 in the case of the lack of electronic temperature regulation.

Summer/Winter toggle

Also on the front of the unit, a manually-operated toggle switch I / 0 / II is installed, which enables switching the unit from winter operation [I] to summer operation [II] with only ventilation, in case the electronic temperature regulation is not present.

NOTE

With electronic temperature regulation the toggle switch must always be switched to position [I] winter operation.

NOTE

Without electronic temperature regulation, swapping both the reset button and the toggle switch through the terminal block M1 inside the burner cabinet in the installation location is recommended.

ATTENTION

The units are equipped with a burner with complete air/gas premix. This mixing process takes place in the fan of the burner motor. The air suctioned in by the fan ﬂows through the Ventura tube, where an underpressure is created, which draws in the gas. In the process, a constant air/gas mixture is created. The ratio of air and gas pressure is 01:01. This value can be changed through the offset regulating screw found on the gas valve. The amount of gas is already adjusted upon delivery of the units and the screw is sealed. With the adjusting screw located at the Venturi tube, a ﬁne adjustment can take place, which regulates the maximum gas ﬂow rate and thus determines the carbon dioxide (CO2) content of the exhaust

The screw is not sealed in order to enable conversion of the fanassisted air heater to another type of gas.

PLEASE NOTE: For the offset and CO2 adjustment.

The control PCB of the units enables the speed regulation of the burner motor with DC depending on the heat output required in the space.

By changing the speed the air ﬂow rate and thus the gas ﬂow rate are changed. Minimum and maximum speeds of the fan are two values that cannot be changed.

The procedure for unlocking the permanent faults F1 and F2 is described in the chapter for the user.

All unit parameters can only be changed in combination with the electronic temperature regulation ATR-6.

REMKO GPM

Modulation

The gas wall heaters are units with ﬂame modulation, whereby the widest range of outputs between the minimum and maximum settings is possible during operation. The highest output serves for raising the room temperature quickly when switching on the units. With the modulation of the ﬂame, on the other hand, the desired room temperature can be maintained at a constant by continuously changing the heat output corresponding to the actual requirement. Thanks to the reduction of the supply air temperature, the physical emergence of layer formation (tendency of the heat to rise) can be limited with this automatic adjustment of the heat output to the requirements of the room. The temperature differences per meter lie under 0.5 °C. If the units work with a reduced heat ﬂow rate, efﬁciency of over 94% is achieved. These results can only be achieved through a precise monitoring of the climactic spatial conditions and an optimal control of the unit. With the dimensioning of heating systems with fan-assisted air

heaters, it is important to observe the number of hourly air renewals. In this regard, we would like to point out the following: Fan-assisted air heaters should, in general, be arranged so that the air ﬂow rate ensures an air renewal of at least twice hourly, even if this would not be necessary for the heat output. The units are serially equipped with a room temperature sensor on the rear side of the unit so that the intake temperature of the fans is monitored. The modulation takes place according to the value measured by this sensor in relationship to the pre-adjusted value on the microprocessor of the control PCB. The optimisation of the modulation temperature value must take place during operation of the system and depends on the distance of the fan-assisted air heater to the ﬂoor and the required temperature conditions.

The fan-assisted air heater is normally installed at a distance of

2.5 - 4 m from the ﬂoor. Thus the desired comfort temperature should be reached and maintained, whereby it should

be ensured that the units are operated at the lowest possible modulation temperature that is necessary to maintain these conditions. The modulation temperature value is set to 21°C at the factory. This value enables a mid-level installation range between 3 and 5 metres with room temperatures between 17 and 18°C (see graph below). To change the modulation value "REG SAN" on the electronic temperature regulation ATR-6 and to read the modulation temperature "TMP MANDATA" with the electronic temperature regulation, see the chapter on instructions for the user.

ATTENTION

Unit parameters can only be changed in combination with the electronic temperature control ATR-6.

Room correction

The use of the electronic temperature regulation ATR-6 is required for this function.

In the following, a type of function is described where the highest possible energy efﬁciency is enabled by the fan-assisted air heater with the help of the control PCB and electronic temperature regulation. In order to start the process of environmental correction, the parameter C1 = 1 must be set. The goal of the room correction function is to begin heating up the area quickly and then to maintain a constant room temperature. In doing so, the formation of layers in the room's air can be reduced in addition to the reduction of the fuel requirement, in particular. The two reference values for the correction are the temperature measured by sensor NTC2 (in the electronic temperature regulation) and the temperature detected by the sensor NTC1 (on the unit). In order to activate the sensor NTC2, change parameter A12 and set to 1. If the room temperature approaches the set value for the set-point, the modulation temperature is changed linearly on the basis of the two parameters A16 and A24.

This enables the operation of the unit at the beginning of the heat requirement and the quick realisation of the pre-adjusted value for the target value of the room. Then the heat output is reduced, whereby the efﬁciency of the unit is increased and the room is heated with less hot air. In this way it is possible to reduce the formation of layers and at the same time reduce heat loss in the room's air. The units are delivered with the following factory settings.

Modulation temperature: „REG SAN“ 24°C Neutral correction range: A24 2°C Correction coefﬁcient: A16 2.5

The parameter A24 determines the range within which the room temperature is corrected. The parameter A16 offers the possibility to increase the efﬁciency of the temperature reduction to the set-point "REG SAN", as shown in the graph. With the standard settings, the modulation temperature, when reaching the room temperature, corresponds to:

„REG SAN“ = 24°C-(2°Cx2.5) = 19°C The correction is independent of the adjusted room temperature. The progression of the room temperatures [ST2] in relationship to the installation height of the units "REG SAN" during the initial heating phase is represented on the graph. Set parameter C1= 0 for deactivation of the correction. With deactivation of the correction, the value "REG SAN" must be correctly regulated in order to avoid the following conditions:

- "REG SAN" set too high:

Strong formation of layers with high heat loss in the ceiling area and subsequently increased energy requirement.

"REG SAN" set too low:

Time to reach the desired room temperature is too long.

With deactivated correction, set "REG SAN" so that the value of the difference in meters between room and modulation sensors multiplied by 0.4/0.5 °C is greater than ST2. To change the modulation value "REG SAN" on the electronic temperature regulation and to change all described values, continue reading the manual.

Instructions for the user

The safety notes on the preceding pages must be observed without fail. The activities of the user are limited solely to the actuation of the switches for operation of the unit. A brief description of the modes of operation of the units with and without accessories follows.

Operation without accessories

This mode of operation is available with every unit. It is a mode of operation that enables immediate operation.

NOTE

For correct operation it is necessary to connect at least one room thermostat in order to be able to switch the burner on and off.

Switching on and off

The procedures for switching on and off take place by closing and opening the contacts 7-9 of the terminal block M1, which is found in the switch cabinet.

ATTENTION

The units may never be disconnected from the mains prior to the completion of the follow-up cooling phase (except in emergencies).

Summer/winter conversion

The units are equipped with a single-pole toggle switch on the front side, which enables it to be switched from winter operation (with active heating) to summer operation (only ventilation).

By switching on one of the two operating modes the units can be used for both heating or air circulation on warmer days.

To switch on the winter phase, the toggle switch only needs to be set to the winter symbol.

To switch on the summer phase, the toggle switch only needs to be set to the summer symbol. The contacts 7-8-9 of the terminal block M1 in the burner cabinet are responsible for these modes of operation.

These contacts can also be repositioned in the room by the installer.

See the instructions for the installer for the electrical connections.

ATTENTION

For the correct mode of the summer/winter operation of the unit with a swapping of the contacts in the room, the single-pole toggle switch on the unit must be set to winter operation.

Fault displays

A green and red LED are installed on the front of the unit. The illumination of the green LED means that the unit is connected to the mains. The illumination of the red LED indicates a malfunction of the unit. The cause of the malfunction can be immediately identiﬁed by the different types of ﬂashing / illumination of the red LED:

F1 - LED continuously lit F2 - LED ﬂashes twice quickly F3 - LED ﬂashes three times

quickly F4 - LED ﬂashes four times quickly F8 - LED ﬂashes continuously F6 - red and green LED blink

alternately

The faults (lock-outs) displayed and saved by the control PCB have the following causes:

F1 - malfunction of the ﬂame

monitoring unit because

of unsuccessful ignition

of the burner; the control

PCB arranges for a series

of automatic deactivation

attempts prior to reporting the

malfunction.

F2 - malfunction of the safety

thermostat. If the temperature

detected by the thermostat

is set too high, it disconnects

and disables the operation of

the unit.

F3 - Burner fan defect;

combustion air fan is defective

or the signal to the control

PCB lies beyond the tolerance

range of the desired speed.

Unlocking

Operation with electronic temperature regulation ATR-6

F4 - Sensor defective or not

connected - the value of the sensor lies beyond the range of measurement; both at NTC1 (supply air) as well as NTC2 (room air).

F6 - Malfunction of the control

PCB because of continuous and repeated unsuccessful ignition attempts of the unit for a predetermined length of time. In the event of this malfunction, the LED also illuminates to signalise a fault that is present directly at the control PCB. For the resetting procedure, see comments in the section on resetting.

F8- The control PCB has

transmitted the start signal to the ﬂame monitoring unit, but the signal of the successful start has not been received; possible ﬂame monitoring unit defect.

The faults F1 and F2 are caused by safety devices and therefore are permanent: The fault persists when switching off and restarting the mains voltage and can only be unlocked manually.

The faults F3, F6 and F8 must be manually unlocked or by switching the mains voltage on and off again for the supply of the unit.

With malfunction of the fanassisted air heater, it can be manually unlocked directly on the unit. There is a reset button for this purpose on the rear side of the unit.

Press and release the reset button to unlock the unit. The red LED extinguishes and the unit resumes its normal operation.

The installer can, if necessary, reposition the reset button in the room and connect it to the contacts 6-9 of the terminal block M1 in the burner cabinet.

See the instructions for the installer for the electrical connections.

ATTENTION

If the unit remains disabled after two or three renewed ignition attempts, customer service should be notiﬁed.

NOTE

If a fault type F6 is present on the unit, the red LED is continuously lit and the unit is switched off. If the unit does not restart when pressing the reset button (unlock), the sensor remains disabled.

The units operates fully automatically through a selfmonitoring electronic control PCB, which is responsible for all monitoring and control functions of the unit. The electronic temperature regulation ATR-6, which is also microprocessor-controlled, is intended for the regulation of the room temperature.

The electronic temperature regulation and the control PCB monitor all control and regulation functions, whereas the ﬂame monitoring unit and the safety thermostat assume the safety functions.

PLEASE NOTE: In the present menu TIME is based on the timer function. Thus it is a different TIME function than described in the preceding section.

HTG - AUTO heating mode

With key K1 (AUTO) the automatic operation of the room thermostat takes place; the operation of the unit in heating mode depends on the programming of the HTG programming timer (read further below in the handbook for this). The activation of the AUTO heating mode is shown on the display by illumination of the programming timer display. In this state the value of the desired room temperature can always be changed with the keys K+ or K-, whereby the adjusted room temperature is shown on the display and the information TEMPERATURE MAN appears. The value can be selected within the range provided for the room temperatures. This status is shown on the display with the hand symbol. With the initial programme change, the electronic temperature regulation automatically functions again in the HTG heating mode.

With key K2 (ON) the continuous and manual operation of the room thermostat takes place. The operation of the unit in the heating mode depends on the selected room temperature. The value of the desired room temperature is shown on the display (TEMPERATURE MAN); the ﬂashing signalises the possibility of changing this value with the keys K+ and K-. The value can be selected within the designated range for the temperature. After the end of the pre-adjusted time for the temperature selection, the display from the menu mode heating ON returns to the display of the operating menu. The value of the desired room temperature can be changed with the keys K+ or K- in this status, whereby it can be selected within the pre-determined range for room temperatures. The activation of the mode heating ON is shown on the display by the disappearance of the programming timer display.

HTG - OFF heating mode

With key K3 (OFF) the heating mode is deactivated. The activation of the heating OFF mode is shown on the display through the disappearance of the heater symbol and the appearance of the programming timer display.

Instructions for the installer

The following instructions for installation and set-up of the units are intended exclusively for authorised technicians. All safety notes must be observed without fail.

General information

Normally the units can be installed directly in the room to be heated. With set-up of the units, the guidelines of the regional building regulations (LBO) and combustion plant order (FeuVO) of the respective state must be observed. The ﬁrst enactment of the (German) Federal Emission Control Act (1st BlmSchG) and the statutory provisions of the ordinance over small combustion plants (1st BlmSchV) must also be applied. The installation of fan-assisted heaters operated with gas burners is prohibited in the following spaces:

■

In public function rooms or in

rooms with a concentration of people greater than 0.4 per square metre.

■

In rooms where gas or dust

can accumulate through the processing that takes place there or through the materials stored there, which could lead to ﬁre or explosion

So that no dangerously high temperatures are reached, the distance between the exterior surface of the equipment and ﬂue gas pipe and potentiallyaccumulated ﬂammable material may be no less than 1.5 m, with a ground clearance of 2.5 m or greater.

Units with gas burners for gas with a thickness greater than 0.8 (liquid gas, propane, butane) may only be installed in rooms where the ﬂoor does not lie below ground level.

Ventilation openings

The rooms where gas-powered units are operated must have one or more permanent openings (windows or doors).

These openings must be arranged in the following places:

- directly below the ceiling with gases with a thickness less than

0.8:

- directly above the ﬂoor with gases with a thickness greater than or equal to 0.8..

The openings must be arranged on exterior walls in open air. For the size of the cross-section, the installed heat output is authoritative.

Installation instructions

The minimum height and clearance of the fan-assisted heater from the walls and ﬂoor can be gathered from the drawing below.

The minimum clearances are the necessary distances for maintenance. All measurements are given in mm. The height [2500 mm] corresponds to the minimum height indicated for "Hanging equipment" by the guidelines.

Hanging from the ceiling

For hanging the units by means of eyebolts, the Mounting set for ceiling installation with horizontal air outlet is available as an accessory item.

Computerised part no.: 228765 .

Flue gas connection

The units work with a closed combustion cycle. The air outlets are located in front of the heat exchanger.

The ﬂue gas evacuation and/ or combustion air supply must be planned and executed in observance of the respective local guidelines. In addition, installation on outside walls must be coordinated with the responsible district master sweep. The classiﬁcation of the different installation versions takes place pursuant to the European Standard EN 1020 and/or DVGW-TRGI Directive 2008 and is a component of the EC authorisation in the factory-supplied design.

Individually, the units are classiﬁed for the following versions:

The installation of the ﬂue gas and supply air duct can take place in different ways.

e.g. Gas ﬁreplace type B:

The combustion cycle is not compact compared to the environment in which it has been installed. The combustion air is taken directly from the installation space.

This version may only be installed in rooms that have at least one door or window that can be opened to the outside and have a volume of at least 4 m³ per kW total nominal heat output of the unit; or a combustion air opening of at least 150 cm² leading outside or two openings that have a clear cross-section of at least 75 cm² each.

We reserve the right to modify the dimensions and constructional design as part of the ongoing technical development process.

e.g. Gas ﬁreplace type C:

The combustion cycle is compact compared to the environment in which it is installed. The combustion air is fed from outside.

The units may only be operated with appropriate ﬂue gas pipe. The factory components available as serial accessories correspond to all requirements.

ATTENTION

The use of plastic ﬂue gas pipe is not permitted.

Condensate

If necessary, the ﬂue gas pipe must be insulated in order to prevent the accumulation of condensate.

The temperature of the ﬂue gas with minimum heat ﬂow rate corresponds approximately to the condensation temperature. With pipe lengths of greater than 5 m (indoors) or 3 m (outdoors), condensate should be eliminated by the following means:

■

Through heat insulation of the

ﬂue gas pipes

■

Through the use of condensate

traps, where the collected condensate is drained from the ﬂue gas pipe.

Note:

Appropriate condensate traps are available as accessories. They can be used with both horizontal and vertical pipework.

Guide to selection

If an endpiece is not connected directly to the unit, whereas a certain length must be overcome, it must be ensured - according to the length and geometry of the segment - that the end and extension pieces, as well as the elbows, exhibit the proper diameter.

After fastening the segment, the pressure loss for the individual parts should be determined depending on the respective unit in use.

The pressure loss is different with each part because the ﬂue gas ﬂow rate is different.

Add up the determined pressure losses of the individual parts and make sure that the total does not exceed the value available for the unit type to be used.

If there is a combustion air supply duct, the pressure losses must be added to those of the ﬂue gas pipe.

If the total of the losses should exceed the available pressure, pipe with a greater diameter must be used, whereby the calculation must be re-computed.

NOTE

Exceeding the permissible pressure decreases in the pipework reduces the heat output and safe operation of the equipment.

The maximum possible duct lengths between the unit and endpiece are shown in the table.

With use of elbows it is necessary to remove the corresponding length from the available duct length for the planned elbow.

Examples:

Elbow Ø 80 90° corresponding length 1.7 m

Elbow Ø 80 45° corresponding length 0.8 m

Elbow Ø 100 90° corresponding length 1.9 m

Elbow Ø 100 45° corresponding length 0.9 m

Examples for the design of ﬂue gas ductwork and combustion air ductwork are represented on the following pages.

Individually, the units are classiﬁed for the installation versions:

Installation examples

Gas ﬁreplace type B23

Room-air-dependent combustion system.

The combustion cycle is not compact compared to the environment in which it has been installed. The combustion air is taken directly from the installation space. The guidance of the ﬂue gas can take place in two variants:

a) with the aid of horizontal

ductwork (outside wall installation) straight through the outside wall, or

b) with a vertical duct through the

roof, if the ceiling is the roof.

With these installation variants, sufﬁcient ventilation of the installation space must be ensured in order to guarantee the correct supply of combustion air. This takes place through openings in the walls of the room. The dimensions and characteristics determined in the standards must be adhered to. In particular, DVGW-TRGI 2008 Sec. 5.2.2 and TRF Sec. 7.2.2. should also be observed.

Electrical connection

The electrical connection of the unit may only be carried out by authorised technicians (electrical power company-approved) in accordance with the applicable regulations. A main/emergency shutoff switch should be installed in an easily accessible position on the visible side of the unit and protected against unintended actuation. The switch must disconnect all poles from the unit with a minimum contact opening of 3 mm from the mains.

ATTENTION

A multipolar isolator with appropriate electrical protection must be connected upstream to the units. The wire cross-section must be at least 1.5 mm².

Electronic temperature regulation ATR-6 connection to the control PCB

Connect the plug of the electronic temperature regulation to the customer-installed bus cable, pull out the 2-pole plug connector [CN] with resistor from the control PCB and re-connect the installed plug with bus cable.

ATTENTION

The main/emergency shutoff switch may only be used in emergency situations or with extended periods of non-use. If it is switched off during the operation of the unit, the electrical supply-air fan cannot cool the combustion chamber. This can result in damage to the unit.

We reserve the right to modify the dimensions and constructional design as part of the ongoing technical development process.

Gas connection

The installation of the gas connection may only be executed by authorised technicians (authorised by the municipal gas supplier) in observance of the applicable provisions for the respective gas type. The cross-section of the ductwork should be determined according to the connection value of the unit, the total output resistance as well as the amount of gas supply pressure. The necessary gas supply pressure (depending on gas type) should be ensured on site. The necessary amount of gas and the necessary gas pressure must be continuously available during operation of the unit according to its output. The unit connection takes place through an R 3/4“ or R 1“ external thread connection. The gas supply should be executed with a suitable, removable screw connection free of voltage and vibration. The components described in the applicable gas guidelines as well as the locally required components in the gas supply, such as

gas pressure regulators, isolation devices, etc. are not included in the scope of delivery and must be provided by the customer. Installing a high-output compatible gas ﬁlter without pressure regulator is also recommended, because the ﬁlter area of the serial ﬁlter installed above the gas valve is limited. The applicable standards allow a maximum pressure of 60 mbar in the heating room; higher pressure values must be reduced prior to entrance to the heating or installation room of the unit. Prior to the initial commissioning, the gas supply line must be thoroughly cleaned and bled through appropriate measures. It must be ensured that the connection of the unit to the gas supply line is executed gas-tight. All screw connections of the unit and the gas supply must be inspected for leakage integrity. With use of leak detection sprays, they must correspond to DIN 30657 (non-corrosive).

ATTENTION

Installation work on the gas system and the supply lines may only be conducted by licensed technicians.

Commissioning

The initial commissioning may only be carried out by a contract installation company or the factory customer service department. Carry out the following steps prior to the initial commissioning:

ATTENTION

Installation and maintenance work on the unit as well as the gas burner may only be carried out by authorised qualiﬁed technicians!

1. Inspect all connections and screw connections of the unit and the gas connections for leakage integrity.

2. Check all electrical screw and plug connections within reach.

3. Check the electrical connection for polarity and the voltage supply (230V/1~/50Hz).

It must be ensured that a gas supply pressure that conforms to standards is continuously present in accordance with the locally available gas type. The gas of the network must be consistent with the gas category to which the unit is adjusted.

For commissioning of the burner, proceed as follows:

1. Loosen the lock screw in the pressure tap of the burner. Do not unscrew completely!

2. Connect a suitable pressure measurement device, e.g. U-pipe pressure gauge, min. resolution 0.1 mbar.

3. Open the gas shut-off devices.

4. Switch on the main/emergency switch.

The appearance of a small ﬂame on the display indicates that the burner is switched on.

It is possible that the ignition burner does not ignite with the initial commissioning, because there is still are in the gas line, whereby the unit triggers a fault.

The unit must be unlocked and the starting procedure repeated.

ATTENTION

A functional inspection of the entire unit including leakage inspections of all gasconveying connections must be conducted.

Combustion analysis

4. Check whether the unit is properly connected to an effective grounding system that corresponds to the applicable safety standards. Only then is the electrical safety and function of the unit guaranteed.

ATTENTION

Gas lines may never be used for the grounding of electrical equipment!

5. Check whether the electronic temperature regulation ATR-6 is serviceably connected.

The units are delivered preadjusted from the factory according to the desired type of gas.

5. Set the room temperature requirement at the electronic temperature regulation ATR-6 to a higher value than the present room temperature.

6. Set the mode selector switch on the front side of unit to the "Heating" position.

7. Set electronic temperature regulation to "MANUAL MODE".

8. Make sure that the heating symbol illuminates on the display of the electronic temperature regulation (mode).

9. Set the heat requirement temperature higher than the temperature measured by the room thermostat or the electronic temperature regulation.

Start the burner and bring it up to "high output" after switching on the fan by holding the reset button on the front side of the unit depressed for 2-3 seconds.

High output mode is shown by a single ﬂash of the green LED on the front side of the unit.

Make sure that the gas pressure at the input to the gas valve corresponds to the prescribed value; otherwise make adjustments.

After approx. two minutes connect a ﬂue gas analytical device to the ﬂue gas pipe and read the CO2 value.

Compare this value to the information in the table "Gas settings" for the type of gas in use.

If the value lies beyond the indicated range, make adjustments with the CO2 regulating screw at the Venturi tube.

- When tightening, the gas ﬂow rate is reduced and the CO2 value along with it

To change the values, pull out the metal plug and use the regulating screw:

- When loosening, the CO2 value is reduced.

- When tightening, it increases.

If the unit is not set to "Normal" operation, the control PCB automatically resets the unit after 20 minutes.

This also happens if the power supply of the unit is switched off and then on again.

- When loosening, the CO2 value increases.

Then set the burner to "minimum output" by pressing the reset button again and holding it for 2-3 seconds.

The "minimum output" mode is displayed by two quick ﬂashes of the green LED.

Wait until the minimum output at the burner has stabilised and check that the CO2 value is the same or slightly below the CO2 value of the high ﬂow rate (up to -0.3%).

With deviating values, use the offset screw.

After any changes to the offset regulation the CO2 value at high output must be checked again through the steps indicated above.

After these steps, set the burner to "Normal" operation by pressing the reset button again and holding it for 2-3 seconds.

This mode is displayed through the continuous illumination of the green LED.

After completion of all steps for the initial commissioning, the user is instructed in the use of the unit and its regulation.

ATTENTION

The input of the Venturi tube may in no case be covered with your hands or other objects. This can lead to ﬂashback of the premix burner.

ATTENTION

If the unit should not be used for extended periods of time, the gas cocks must be closed and the main switch of the unit must be switched off.

Maintenance

In order to preserve the performance and a long service life of the equipment, some mandatory inspections must be carried out once annually and in each case prior to the beginning of the heating season:

1) Check condition of the ignition

and monitoring electrodes as well as the ignition gas burner

2) Check condition of the supply

and ﬂue gas lines as well as the end pieces

3) Inspect Venturi tube for dirt

4) Inspect heat exchanger for dirt

5) Check gas pressure at the input

to the gas valve

6) Check function of the ﬂame

monitoring unit

7) Check of the safety

thermostat(s)

8) Inspection of the ionisation

current (>2 microamperes)

NOTE

With steps 1, 2, 3 and 4 the power and gas supply to the unit must be interrupted. Steps 5, 6, 7 and 8 take place in the unit heating mode.

1) Inspection of the electrodes

Completely disassemble the ignition burner and clean gas net and gas nozzle with compressed air. Check the ceramic of the electrodes for integrity. Carefully remove any oxidation accumulation on the metal part of the electrodes with ﬁne emery paper.

Check electrodes for their positioning according to instructions (see ﬁgure).

2-3 mm

It is important that the monitoring electrode [IO] lies tangential to the ignition burner head and not within it. The ignition electrode [Z] must discharge to the outside edge of the ignition burner at an appropriate distance to the monitoring electrode.

2) Inspection of the ﬂue gas and supply air lines

Carry out a visual inspection of the status of all lines and connectors. Remove any accumulation of dirt that has formed on the endpiece of the supply air line.

3) Inspection and cleaning of the Venturi tube

Remove the dirt at the input of the Venturi tube with a small brush or other suitable tool. Make sure that it does not fall into the Venturi tube.

4) Check of the gas input pressure

Make sure that the pressure at the input of the gas valve corresponds to the prescribed value for the respective gas type. This check must be carried out with the unit switched on at high output.

5) Inspection of the ﬂame monitoring unit.

Close the gas cock in the unit heating mode and make sure that the fault F1 occurs. Open the gas cock again, unlock and wait for the unit to restart.

6) Check of the safety thermostat(s)

The inspection must be carried out in the unit heating mode.

- Heat up the thermostat sensor

with a hot air gun or other suitable means until the fault F2 is displayed..

- Let the thermostat sensor cool

down and reset the unit again.

- This check should be carried out

at all existing thermostats.

REMKO GPM

7) Inspection of the ionisation current

Carry out the inspection with a tester that is capable of detecting microampere values with DC.

- Interrupt power supply to the

unit.

- Disconnect cable from the ﬂame

monitoring unit and connect to the minus terminal of the tester.

- Connect a cable from the positive

terminal of the tester to the ﬂame monitoring unit.

- Switch on the unit again and

measure the ionisation current.

The value of the ionisation current must exceed 2 microamperes.

8) Inspection and cleaning of the heat exchanger

Thanks to the fault-free combustion of the unit, only minimal deposits normally accumulate. However, deposits may accumulate in the pipes of the heat exchanger over the course of time. Therefore, adherence to the normal maintenance intervals is mandatory.

A symptom of deposits in the heat exchanger may be the noticeable reduction of heat output.

To clean the heat exchanger, carry out the following steps:

- Allow the unit to cool down and disconnect from the mains supply.

- Open the side door of the unit.

- Remove the fastening screws of the cladding [A] of the ﬂue gas collector bin.

- Clean the interior of the pipe along the entire length with a suitable pipe brush, whereby the dirt should be advanced to the collector bin as far as possible, where it can then be suctioned out.

- After completion of cleaning, reinstall the cladding [A] of the ﬂue gas collector bin and check for tightness.

- After the work is completed, switch on the unit again and conduct a test run.

Lower values are a sign of poor positioning or oxidised electrodes.

Replacement of the gas valve and CO2 and offset regulation

Unit without electronic temperature regulation

With replacement of the gas valve, the CO2 and, if applicable, the offset value must be adjusted.

- Start the burner and bring it to "high output" after switching on the fan by holding the reset button on the rear side of the unit depressed for 2-3 seconds.

High output mode is shown by a single ﬂash of the green LED on the front of the unit. After approx. two minutes connect a ﬂue gas analytical device and read the CO2 value. Compare this value with the information in the table "Gas settings" for the type of gas in use.

- If the value lies beyond the indicated range, use the CO2regulating screw at the Venturi tube.

With deviating values, use the offset screw.

To change the values, unscrew the metal plug and use the regulating screw:

When loosening, the CO2 value decreases.

When tightening, it increases.

After any changes to the offset regulation, the CO2 value at high output must be checked again through the steps indicated above.

After these steps, set the burner to "Normal" operation by pressing the reset button again and holding it for 2-3 seconds.

This mode is displayed through the continuous illumination of the green LED.

NOTE

- Switch on the burner. After approximately two minutes after starting, it goes to its highest ﬂow rate.

Connect a ﬂue gas analytical device and read the CO2 value. Compare this value with the "Gas settings" (page 32) for the type of gas in use.

- If the value lies beyond

the indicated range, use the CO2regulating screw at the Venturi tube.

When tightening, the gas ﬂow rate is reduced and the CO2 value along with it.

When loosening, the CO2 value increases.

Then, at minimum output, set the burner to a value that lies below the measured temperature by adjusting the REG SAN value.

When tightening the adjusting screw the gas ﬂow rate is reduced and the CO2 value along with it

When loosening, the CO2 value increases.

Then set the burner to "minimum output" by pressing the reset button again and holding it for 2-3 seconds. The "minimum output" mode is displayed by two quick ﬂashes of the green LED.

- Wait until the minimum output at the burner has stabilised and check that the CO2 value is the same or slightly below the CO2 value of the high ﬂow rate (up to -0.3%).

If the unit is not set to "Normal" operation, the control PCB automatically resets the unit after 20 minutes.

This also happens if the power supply of the unit is switched off and then on again.

Unit with electronic temperature regulation

With replacement of the gas valve, the CO2 and, if applicable, the offset value must be adjusted.

- Adjust the regulation parameter of the sensor NTC1 ("REG SAN" on the electronic temperature regulation) higher than the value measured by the sensor NTC1 ("FLOW VL" on the electronic temperature regulation).

- Wait until the minimum output at the burner has stabilised and check that the CO2 value is the same or slightly below the CO2 value of the high ﬂow rate (up to -0.3%).

With deviating values, use the offset screw.

To change the values, unscrew the metal plug and use the regulating screw:

When loosening, the CO2 value decreases.

When tightening, it increases.

After any changes to the offset regulation, the CO2 value at high output must be checked again through the steps indicated above.

Conversion to liquid gas

The on-site conversion of the gas type may only be carried out by authorised, qualiﬁed technicians.
