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, the material in the chimney breast 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.
• Comply with the minimum required internal sizes of the chimney breast.
• Vent the chimney breast by means of ventilation holes with a combined passage as stated further down in
the text.
• 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
5.8 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.
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.

English
INSTALLATION MANUAL
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.
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.
• The existing chimney should be tight.
For setting the appliance, the same conditions/instructions apply as for the concentric system described above.

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.

• Connection via a ‘modbus’ protocol.
• Control via an application.
!Caution Only 1 type of wireless connection is possible on the communication module.
6.2.2.1 Connection via ‘modbus’ protocol
Wireless connection of a Domotics system to the receiver is possible via a connection according to the ‘modbus’
protocol. Such a connection can only be established with a communication module (see Appendix 3, fig. 35 (W)).
This module can be ordered from DRU. This communication module translates the ‘modbus’ protocol from the
Domotics system into a wireless signal to the receiver.
When connecting a Domotics system via the communication module to the receiver, proceed as follows:
Ø Use the remote control to test whether the location where the communication module will be placed is within the
reach of the receiver.
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
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
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 the communication module.
Ø Use the instructions for the application in order to install it.

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.
• The main burner(s) must cross the full burner smoothly and without popping and continue to burn.
• If the appliance does not ignite after three restarts and enters hard lockout, it may never be reset by
disconnecting it from the power supply. If a restart is necessary after all: remove the glass pane and make sure
the gas is able to escape from the appliance. After this, the appliance may be disconnected from the power
supply for 10 seconds. After these 10 sec., the power supply may be reconnected. Ignite the appliance in the
same way as the first ignition, as indicated in section 7.3.1.
Ø Check operation of the main burner from a cold condition.
Ø If sparks are determined between the ignition electrodes, the main burner should burn within a few seconds.
!Tip The flame picture and a good flame transfer can only be properly judged if the glass window is installed.
Use the malfunction search diagram (Appendix 1) if the ignition of the main burner does not comply with the
above-mentioned requirements.
7.4 Flame picture
