3. SAFETY
3.1 General
!Caution • Observe the generally applicable regulations and precautions/safety instructions in this manual.
• First check – in appendix 2, table 2 – whether the appliance to be installed has the correct technical version.
• Read the manual carefully to ensure a proper and safe installation of the appliance.
• Observe the regulations/instructions in this manual.
3.2 Regulations
Please install the appliance in accordance with the applicable national, local and constructional (installation)
regulations.
3.3 Precautions / safety instructions at installation
Carefully observe the following precautions/safety regulations:
Ø The appliance may only be installed and maintained by recognised installers who are skilled in the field of gas
heating and electricity.
Ø Do not make any changes to the appliance.
Ø When installing a built-in appliance:
• Use non-combustible and heat-resistant materials for the chimney breast, including the top of the chimney
breast and the material in the chimney breast, such as the floor under the appliance and the back wall against
which the appliance will be placed. For this you can use both sheet material and stone-like materials.
• Take sufficient measures to prevent temperature of a wall behind the chimney breast becoming too high,
including the materials and/or objects behind the wall.
• Take the minimum required internal dimensions of the chimney breast into account. These are for the benefit
of safety and for the prevention of excess heat accumulation in the chimney breast.
• Vent the chimney breast by means of the ventilation holes (see table 4-1). These are essential for ensuring
safety and for the prevention of excess heat accumulation in the chimney breast.
• Use heat-resistant electrical wiring.
• Place heat-resistant electrical wiring away from the appliance and as low as possible in the chimney breast.
This has to do with the temperature development in the chimney breast.
Ø Only use the flue gas discharge / combustion air supply system supplied by DRU.
Ø When installing a free-standing appliance: place the appliance away from the back wall by the minimum distance
stated further down in the text.
Ø Do not cover the appliance and/or do not wrap it in an insulation blanket or any other material.
Ø Keep combustible objects and/or materials outside the appliance's radiation range. This radiation range is
500 mm, unless stated otherwise.
Ø Only use the accompanying set, such as the wood or pebble set, and place it exactly as
described.
Ø Leave space around the ionisation pin and spark electrode and never place glow material around these pins.
Ø Make sure there is no dirt in gas pipes and connections.
Ø Place a gas tap in accordance with applicable regulations.
Ø Prior to putting into operation, check the complete installation for gastightness.
Ø Prevent blocking of the explosion hatch(es) at the top and/or bottom of the appliance and check whether it/they
connect(s) properly to the sealing surface before the appliance is built in.
Ø Do not ignite the appliance before the gas, discharge and electric connections have been fully installed, first
observe the procedure described in chapter 7.3.
Ø Do not use the appliance when a pane is broken and/or cracked, until it has been replaced.
Ø The appliance was designed for atmospheric and heating purposes. This means that all visible surfaces, including
the glass pane, can become hotter than 100C°. It is recommended to always place a protective grating in front of
the appliance when there are children, elderly people or handicapped persons in the same room as the appliance.
If it is possible that vulnerable people are regularly present in the room with no supervision, a fixed guard should
be mounted around the appliance.

INSTALLATION MANUAL
3.4 Principle of ignition cycle
Below you will find a brief description of how this appliance is ignited. The receiver in the appliance will get a
signal from the remote control to start the ignition process. The receiver will get the signal to start the ignition
process. This signal is passed on to the burner device, after which, if applicable, the relay for the Powervent
System® is switched. After an 8 second interval, the ignition on the spark electrodes will start. If no Powervent
System® is connected, only the relay will switch and the ignition will start immediately. The main burner will be
ignited at about 50% of its capacity. This will prevent a larger amount of gas in the combustion chamber, if no
ignition takes place. When the gas ignites, ionization will have to be detected. In order to make sure the flame has
passed over, this will take place at the other side of the burner. When ionization is detected, the gas control will
modulate to 100%.
In case of an appliance with a switchable second burner, the second valve is switched (you will be able to hear a
'click') in order to ignite the second burner. After ignition of the second burner, the appliance will always go to the
full position (full capacity). This will guarantee that the second burner will actually ignite. The second burner can
be switched on and off manually, by means of the remote control. In case of switching on manually, the appliance
will first return to full load.
!Caution The appliance's control unit is characterized by stringent safety requirements. It is possible that the burning
appliance switches off automatically and then switches back on again. This is not a failure, but a check.
The moment the appliance's control unit is connected to mains voltage, the control unit will perform this check
every 24 hours. If the appliance is burning at that time, the appliance will extinguish and then start again
immediately.
If you wish to prevent this, you can remove the plug and insert it again at a time during the 24 hours when the
appliance is never or hardly ever burning.
4. Removing the packaging
Note the following items when removing the packaging:
Ø Remove all packaging materials.
Ø Remove all supplied components in, on and/or at the appliance.
Ø Check the appliance and accessories for damages (during transport).
Ø If necessary, contact your supplier.
Ø Never install if an appliance is damaged!
Ø Remove any screws that are used to fix the appliance to a platform or pallet.
!Caution The glass pane(s) is/are made of a ceramic material. Very small irregularities in the glass panes cannot be avoided,
but are within the required quality standards.
!Caution Keep plastic bags away from children.
Appendix 2, table 1 indicates which components should be available after unpackaging.
Ø Contact the supplier if you find that not all components have been supplied.
Ø Packaging must be disposed of in accordance with the regulations.

INSTALLATION MANUAL
5. Installation
5.1 Type of gas
The data plate indicates for which type of gas, gas pressure and for which country this appliance is intended.
The data plate can be found on the appliance or can be attached to a chain to which it should remain attached.
!Caution Check whether the appliance is suitable for the type of gas and gas pressure used at the location.
5.1.1 Reconstruction to different type of gas
In order to convert this appliance to a different type of gas, please contact DRU's service department and ask for
the possibilities.
5.2 Gas connection
Place a gas tap in the gas pipe in accordance with the applicable regulations.
The gas connection on the gas control is located next to the receiver (see Appendix 3, fig. 38 (G)).
!Caution • Make sure there is no dirt in the gas pipes and connections.
• No soldering may take place at the flexible gas hose(s), as this could cause leaks.
The following requirements apply to the gas connection:
• Use a gas pipe with the correct dimensions, so that no pressure loss can occur.
• The gas tap must be approved (in the EU this will be the CE mark).
• You should always be able to reach the gas tap.
5.2.1 Gas hose for gas connection
In many cases, a gas hose for a gas connection according to EN14800 can be ordered together with the appliance
(consult druservice). The gas hose is mounted to the appliance and has been checked for leak-tightness. This gas
hose is available in different lengths.
!Caution Take the following into account when installing the gas connection and the appliance (see Appendix 3, fig. 42 and
43):
• The gas connection must always be accessible to be able to shut off the gas supply.
• The gas connection may only be mounted vertically, so that the gas hose can be connected vertically at the
bottom.
• The gas connection is permitted in a zone (blue hatched area in the figure):
- To the left and right of the appliance to a height of 30 cm above the bottom side of the appliance (the
bottom side is the end of the adjustable feet holder, without the feet).
- Under the appliance in the area between the legs.
• The gas connection and gas hose should not be placed behind the appliance.
• The gas hose may not get above the bottom side of the appliance (the bottom side is the end of the foot
without the adjustable feet)
• The minimum bend radius of the hose is 40 mm.
• The hose should be placed as low as possible, must have a minimum distance from the appliance of 20 mm
and, if possible, should not be placed under the burner.
• The entrance of the gas control in which the hose is mounted faces the appliance. Due to the required
minimum bend radius, the chimney breast width becomes larger on the side of the control hatch. With this
gas hose, the depth of the control hatch is not 230 mm, but will now be 270 mm.
5.3 Electric connection
In case of a 230 Volt electrical connection, provide proper grounding. Place this electrical connection away from
the appliance, as low as possible in the chimney breast. This has to do with the temperature development in the
chimney breast.
!Caution Make sure that it is easy to disconnect the appliance from the power supply after installation;
• by disconnecting the plug;
• or by means of a 2-core switch installed by a recognised installer in accordance with current regulations.
!Caution • Protect the gas control and electric components, hereafter referred to as the gas control, against building
dust and moisture!
• For connecting the receiver and control panel at an appliance equipped with the CM system ®, you must
observe the instructions in the supplied manual.

5.3.1 Connecting the switch contact (if applicable)
It is possible to operate one or more lamps (in case of several lamps, a maximum of 0.5A/250VAC/30VDC) via the
remote control of the appliance. You could think of the lamps of Dru's lux elements. For this, you can use switch
contact B on the receiver (see appendix 3, fig 36). The switch contact is not polar sensitive.
5.3.2 Connection extra power supply (max. 80W, 230VAC) (if applicable)
This connection is ideal for possible lighting or a ventilation system in the chimney breast and can be operated by
means of the remote control (see appendix 3, fig. 36 (C)). The power supply of this connection is identical to the
mains voltage and it can be subjected to a maximum load of 80 Watts.
5.4 Placing the appliance
!Caution • Place the appliance in front of a heat-resistant and non-combustible wall and on a heat-resistant and
non-combustible floor. The wall brackets on a built-in appliance ensure that the minimum distance to the
wall is maintained.
• Ensure there are no combustible objects or materials present in the fire's radiation range, within a distance of
500 mm, unless indicated otherwise.
• Place the concentric system in such a way that no fire hazard is ever created (also see section 5.8).
• Take sufficient measures to prevent temperatures of a possible wall behind the chimney breast, or the floor
under the chimney breast from becoming too high; including the materials and/or objects located there.
• Do not cover the appliance and/or do not wrap it in an insulation blanket or any other material.
• Make sure that the appliance to be installed has a stable position. Fasten possible extending legs with the
self-tapping screws.
!Caution When installing a built-in appliance, always take the following into account:
• The minimum construction measurements according to Appendix 3, Fig. 1 and 2.
• The construction height of the appliance.

!Caution Additional instructions for the appliance to be installed can be found from section 5.10.
5.5 Placing a built-in appliance (if applicable)
Not all built in DRU appliances are supplied with a control hatch.
!Caution Built in appliances must be installed with the DRU control hatch. This is necessary to ensure a durable, safe and
proper operation. The DRU control hatch can be ordered separately. Exceptions are:
Appliances with supplied DRU guard cabinet. The DRU guard cabinet is intended for installation with a suspended
platform. If the appliance will be connected to the DRU PowerVent system, the DRU control hatch has to be used
after all.
The gas control is mounted to the appliance. It must be taken out and placed in the control hatch at a later time.
For placing the gas control in the control hatch, see section 5.7.
Proceed as follows:
Ø Loosen the bracket with the gas control by loosening the self-tapping screws and screw the self-tapping screws
back in the appliance.
Ø Place the bracket with gas control, together with the wiring of the ignition/ionisation cable(s), the flexible gas
hose(s) and type plate with chain in the direction of the control hatch.
!Caution The data plate should remain connected to the chain.
Ø Set the height of the appliance using the adjustable feet.
Ø Make the appliance level at the same time.
!Tip The construction frame can be adjusted afterwards for most 2- or 3 sided appliances. This allows a good contact of
the construction frame with the chimney breast. Adjustment should take place before the appliance is built in.

INSTALLATION MANUAL
!Caution Do not ignite the appliance before the gas, discharge and electric connections have been fully installed, first
observe the procedure described in chapter 7.3.
5.6 Placing the chimney breast (if applicable)
For the benefit of a good heat discharge, operation of the appliance and general safety, there should be sufficient
space around the appliance.
The chimney breast should be ventilated sufficiently by means of ventilation holes (incoming and outgoing).
These are essential for safety and for the prevention of excess heat accumulation in the chimney breast.
!Caution When an appliance is built in the floor, please take into account the minimum distances from a combustible
floor. If applicable, additional information about this is provided from section 5.10 'Additional instructions'.
!Caution • Use non-combustible and heat-resistant materials for the chimney breast, including the top of the chimney
breast and the material in the chimney breast, including the back wall and floor.
• The appliance is not a support structure. Make sure the appliance does not have to bear the weight of the
chimney breast for example.
• The passage of the ventilation holes (outgoing), which are placed as high as possible, is stated in Appendix 2,
Table 2.
• If no control hatch is placed in the chimney breast, an air supply of at least 80 cm 2 should be attached as low
as possible. If there is, the control hatch will suffice as air supply.
!Caution When placing the chimney breast, you should take the following into account (see Appendix 3, Fig. 2):
• The location for the control hatch: this must be placed as low as possible.
• The dimensions of the control hatch; see Placing the control hatch section 5.7.
• The location of the ventilation holes (V) (outgoing).
• Maintain a minimum 30 cm distance between the top of the ventilation hole (outgoing) and the ceiling of the
house.
• The measurements of the glass pane, so that it can be placed/removed after placing the chimney breast.
• The protection of the gas control and the pipes against cement and plaster.
• If possible, you should place decorative strips, frames, etc., after any required structural work has been
completed. Prevent the use of painter's tape. If this is not possible: use a good quality painter's tape and
remove it immediately after plastering or painting work.
!Tip You should preferably apply the ventilation holes (outgoing) on both sides of the chimney breast. Use the DRU
ventilation elements.
Check the following issues, before the chimney breast is fully closed:
• Whether the discharge / concentric system is placed correctly.
• Whether the channels, fixing brackets and possible clip bindings, which cannot be reached after installation,
are fastened by means of self-tapping screws.
Ø Do not plaster on or over the edges of the construction frame, because:
• The heat of the appliance could cause cracks.
• It will no longer be possible to remove/place the glass pane.
Ø When using stone-like materials and/or plaster finishing, allow the chimney breast to dry for at least six weeks
prior to taking the appliance into operation in order to prevent cracks.
5.7 Placing the control hatch (if applicable)
The control hatch (also see paragraphs 5.5 and 5.6) is placed as low as possible in the chimney breast.
!Caution • The bottom of the control hatch may not be placed higher in the appliance than the burner surface.
• Place control hatch and bracket with gas control indoors in a dry place only!
A number of components are placed in the control hatch, such as data plate, gas control and, if applicable, the

English
INSTALLATION MANUAL
!Tip The opening in the chimney breast may be made horizontal and vertical.
Ø Place the inner frame (A); unscrew bolts (D and F) for this.
!Caution The inner frame should be placed in the correct way. Two positions are possible. Placing the inner frame with a
rotation of 180° is not allowed (see Appendix 3, fig. 4).
!Tip • When the chimney breast is made of bricks, the inner frame can be built with bricks at the same time.
• In case of a different material, the inner frame can be glued or fastened with four countersunk screws.
Ø Remove the bracket with the gas control (B) from the appliance and place these self-tapping screws back in the
appliance.
Ø Attach the bracket with gas control to the inner frame (A). Proceed as follows:
• Unwind the cables. This will, amongst other things, prevent a poor operation of the ignition.
• Unwind the flexible gas pipe(s).
• Mount the bracket with the gas control to the inner frame (A). The slotted hole falls in allen screw (C); the hole
at the bottom falls over the head of allen screw (D).
• Fix the bracket with allen screw (C).
!Caution • Avoid kinks in the pipes.
• Do not lay the cables of the ionisation and ignition pins along metal parts, wiring and other components.
Ø Connect the gas pipe with gas tap (see section 5.2).
Ø Bleed the gas pipe.
!Tip If the gas tap is closed, the bracket with gas control can be easily removed by loosening the clamp coupling under
the gas control and loosening the allen screw (C) by a few turns. The bracket with the gas control can now be lifted
and removed towards the front out of the control hatch.
Ø Connect the 230V mains voltage with protective earth using the correct type of plug. The other side of the power
cable can be easily connected to the universal 230V plug in the control hatch. Use this universal 230V plug to
disconnect the appliance from the power supply, if necessary.
!Caution If the 230V power cable is damaged, replace it by a similar power cable or a power cable that is available from your
dealer.
Ø Place the data plate in its intended clamp (G).
Ø Mount the outer frame with door (E) to the inner frame using two allen screws (D and F).
!Tip The outer frame can be placed in such a way that the door turns to the left or right.
!Caution Always close the control hatch with the lock (H) because of the electricity behind the door (230V).
You can operate the lock with a fitting flat object.
5.8 Concentric system
5.8.1 General
The appliance is connected to a flue gas discharge / combustion air supply system delivered by DRU, hereafter
referred to as the concentric system. The diameter for this connection is indicated in appendix 2, table 2. The
passage to the outside can be created with a wall terminal (C11) or a roof terminal (C31). If necessary, an existing
chimney can be used (see section 5.8.4).
!Caution • Only use the concentric system supplied by DRU. This system has been tested in combination with the
appliance. DRU cannot guarantee a proper and safe operation of other systems and does not accept any
responsibility or liability for this.
• Use a chimney set for the connection to the chimney, DRU will be able to supply it.
• DRU's concentric system is intended for indoor use and may therefore not be used outdoors, with the
exception of the sections intended for that purpose such as roof and wall terminals.
9

English
INSTALLATION MANUAL
The concentric system is constructed from (the flue spigot of) the appliance.
If, due to constructional circumstances, the concentric system is placed first, it is possible to connect the appliance
by means of a telescopic pipe piece.
5.8.2 Construction of the concentric system
Depending on the configuration of the concentric system, the appliance must be further adjusted with a possible
restrictor slide and/or air inlet guide.
See Tables 4 and 6 for determining the correct adjustment and section 'Adjustment of the appliance' for the
method of working.
The concentric system with wall or roof terminal has to comply with the following conditions:
• In appendix 2, table 4 or 5 you can find whether a concentric pipe should be connected and what the
minimum vertical length would have to be.
• Determine the permissibility of the required configuration.
When using a wall terminal (C11) the following applies:
• The total vertical pipe length, when using a wall terminal, may have a maximum length that can be found in
appendix 2, table 4.
• The minimum vertical pipe length, when using a wall terminal, can be found in appendix 2, table 4.
• The total horizontal pipe length, when using a wall terminal, may have a maximum length that can be found
in appendix 2, table 4 (excluding wall terminal; see appendix 3, fig. 5).
When using a roof terminal (C31) the following applies:
• The construction of the chosen system, when using a roof terminal, must be permissible according to
Appendix 2, Table 5 (See the method of working described below).
The working method below indicates how the permissibility is determined of a concentric system when using a
roof terminal.
1) Count the number of 45° and 90° bends required (15° and 30° bends are also allowed).
2) Count the total number of whole metres of horizontal pipe length.
3) Count the total number of metres of vertical and/or sloping pipe length (roof terminal excluded).
4) In the first 2 columns of Table 5, look for the number of bends required and the total horizontal pipe length.
5) In the top row of Table 5, look for the required total vertical and/or sloping pipe length.
6) A box with a letter means that the chosen concentric system is permitted.
7) Use Table 6 to determine how the appliance should be adjusted.
5.8.3 Placing the concentric system
!Caution • Maintain a distance of at least 50 mm between the outside of the concentric system and the walls and/or the
ceiling (see section 5.4). If the system is built in (for instance) a cove, it should be made with non combustible,
heat-resistant material all around it.
• Use heat-resistant insulation material when passing through combustible material.
• Create a terminal for the concentric system with the following diameters:
- The pipe diameter +25 mm for a passage through non combustible material (see Appendix 3, fig. 40).
- The pipe diameter +200 mm for a passage through combustible material. Insulate the surrounding free
space with at least 60 mm mineral wool (see Appendix 3, fig. 41).
• The rosette of the wall terminal is too small to seal the opening in case of passage through combustible
material. That is why a heat-resistant intermediate plate of sufficient size should first be mounted to the wall.
Then, the rosette is mounted on the intermediate sheet.
The roof terminal can end in a sloping and a flat roof.
The roof terminal can be supplied with an adhesive plate for a flat roof or with a universally adjustable tile for a
sloping roof.
!Caution Some heat-resistant insulation materials contain volatile components that will spread an unpleasant smell for a
prolonged time; these are not suitable.
Place the concentric system as follows:
Ø Build the system up from (the flue spigot of) the appliance.
Ø Connect the concentric pipe pieces and, if necessary, the bend(s).
Ø On each connection, apply a clip binding with silicon sealing ring.
10

English
INSTALLATION MANUAL
Ø Use a self-tapping screw to fix the clip binding to the pipe on locations that cannot be reached after installation.
Ø Attach the concentric system with sufficient fastening brackets, so that the weight is not resting on the appliance.
Observe the following;
• Place the first fastening bracket 0.5 metre from the appliance, at the most.
• Place a fastening bracket maximum 0.1 metre from each bend, if the bends are more than 0.25 metre away
from each other. If two bends are closer to one another than 0.25 metre, 1 fastening bracket between these
bends will be sufficient.
• At least every 1 metre, place a fastening bracket at slanted and horizontal sections.
• At least every 2 metres, place a fastening bracket at vertical sections.
Ø Fasten a roof terminal with anchor cables, if it protrudes more than 1,5 metres above the terminal.
Ø Determine the remaining length for the wall or roof terminal and cut it to size, make sure the correct insertion
length is maintained.
Ø Place the wall terminal with the (groove/folded) seam at the top.
Ø Attach the wall terminal from the outside by means of four screws.
!Caution When using the wall terminal, place the terminal with a downward slope of 1 cm / metre towards the outside, in
order to prevent rain water from raining in.
5.9 Connection to an existing chimney (C91)
The appliance can be connected to an existing chimney. A 100 mm diameter flexible SS pipe is placed in the
chimney for discharging flue gases. The surrounding space is used as combustion air supply.
In case of an appliance connection of ø200/130, 0.8 metres of concentric system must first be connected vertically.
Reduce the concentric system after the first 0.8 metres to a diameter of 150/100. The concentric system of 150/100
can be vertically connected to an existing chimney.
The following requirements apply when connecting to an existing chimney:
• Only allowed when used in combination with the special DRU chimney set. The installation regulation is parat
of the delivery.
• The internal size should be at least 150 x 150 mm.
• The vertical length has a maximum of 12 meters.
• The total horizontal pipe length may have a maximum length that can be found in appendix 2, table 4.
• The existing chimney should be clean.

INSTALLATION MANUAL
6. Control
The appliance is supplied with a wireless black remote control for the user (see appendix 3, fig. 35 (B)). As an option,
an orange remote control can be supplied for the installer (see appendix 3, fig. 35 (O). Controlling the flame height,
igniting and switching off take place through the black remote control controlling the receiver. Some fires can also
be controlled in an alternative way. These options are described further down in this chapter.
The user manual describes the operation of the appliance, including the operation of the remote control and
alternative methods of operation.
!Caution • Do not ignite the appliance before the gas, discharge and electric connections have been fully installed, first
observe the procedure described in chapter 7.3.
• Chapter 6 of the manual supplied applies to an appliance equipped with the CM system.
6.1 Remote controls
6.1.1 Black remote control for the user
Proceed as follows to make the black remote control ready for use:
Ø Place the two penlite batteries (AA) in the battery holder of the remote control.
Ø Make sure the voltage of the atmospheric fire is not switched off for longer than 5 minutes.
Ø If the remote control does not have the "BND" state, the following operations must be performed: Press the menu
button (button with square symbol) on the remote control for at least 10 seconds and then press a few times until
“BND” appears on the screen with the receiving symbol.
Ø Press the “arrow up” and “arrow down” buttons briefly and simultaneously, so that a (flashing) warning triangle and
an hourglass appear in the screen as well.
Ø As soon as logging on is finished, the start screen will appear
!Tip Ale functions are extensively explained in the supplied user manual.
6.1.2 Orange remote control for the installer
By means of the optionally available orange remote control, it is possible to read all information stored in the
receiver. In this way, the last 20 error messages can be retrieved, and it will also be possible to read how many
times an error occurred. Moreover, this remote control can also be used to adjust the basic settings and to read the
size of the ionization flow. It is also required for a wired Domotics control.
6.2 Alternative control (if applicable)
In addition to the remote control, it is also possible to operate the fire in alternative ways. For this purpose, a
Domotics system can be connected to the receiver. This can be a wired or a wireless system. The various
possibilities are described below (see appendix 3, fig. 35, 36 and 37).
6.2.1 Wired
Wired connection of the Domotics system to the receiver takes place via a 0-3VDC direct current
(see appendix 3, fig. 36 (D)).
!Caution A higher voltage than 3V will damage the receiver and is therefore not permitted.
Tip! In case of Domotics systems with an output voltage of 0-10V, you should switch the voltage back to 0-3VDC.
Use a voltage distributor made of resistors. For example, 2200 ohms and 680 ohms. The voltage above 680 ohms
resistance can be used on the input of the 0-3VDC. Low ohmic resistors must be used.
By controlling the height of the voltage, the receiver will be able to calculate the position of the fire. Table “B1” in
appendix 3, fig. 37 shows the relationship between the voltage and the height of the flame. If you have an
appliance with 2 burners, table “B2” will apply. It shows the relationship between the voltage, the height of the
flame and the number of burners.
Proceed as follows when connecting the Domotics system to the receiver:
Ø Connect the 0-3VDC signal to the connector, to which a black and yellow wire are connected
(see appendix 3, fig. 36 (D)).
Ø Use the orange remote control to select the option for a wired connection: go to position 8 in the first menu and
select an appliance with single burner (option 2) or an appliance with two burners (option 3). For this, read the
manual of the orange remote control.

to improve the reception.
Ø Connect the communication module by means of an RJ45 plug, according to the instructions in the manual that is
supplied with this module.
Ø Now follow the steps described in the ‘modbus’ protocol manual. It is available from the supplier of the domotics
system.
6.2.2.2 Control via application
Also when operating the appliance via a tablet provided with the DRU Control App (iOS or Android), you will need
a communication module. This module can be ordered from DRU.
In order to control the fire via an application, proceed as follows:
Ø Using the remote control, test whether the location where you want to place the communication module is within
the receiver's range.
Ø Place the remote control on this location and test the reception sensitivity (RSSI).
Ø Press the on/off button and down arrow at the same time. The value that is now visible, must be between -20 and
-70 (see User Manual, "Reception Sensitivity"). If needed, hold the remote control closer to the appliance in order

English
INSTALLATION MANUAL
!Tip When checking whether the main burner continuous to burn, it is possible that it switches off after 15 seconds. In
that case, this will be caused by the fact that there is no ionization detection and because the glass window has
not been placed. This can be regarded as a situation where the main burner continues to burn.
!Caution • Always wait 5 minutes before re-igniting the appliance.
• No changes may be made to the gas control.
7.3.2 Main burner
!Caution • The ignition electrode should ignite the main burner within a couple of seconds and without popping.
