3.3 Precautions / safety instructions at installation

Carefully observe the following precautions/safety regulations:

You should only install and maintain the appliance if you are a certified and competent installer in the field of gas-fired heating and electricity; do not make any changes to the appliance; if you are installing an appliance that must be built in;

• 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.

if you are installing an appliance type B11 with open combustion: please use a suitable flue gas discharge system that is provided with the CE label; if you are installing an appliance with closed combustion: only use the concentric systems supplied by DRU; if you are installing a free-standing appliance: place the appliance away from the back wall by the minimum distance stated further down in the text; do not cover the appliance and/or do not wrap it in an insulation blanket or any other material; make sure that combustible objects and/or materials have a distance from the appliance of at least 500 mm; only use the accompanying wood/pebble set and place it exactly as described; leave the area around the ionization pin and spark plug free; make sure there is no dirt in gas pipes and connections; place a gas tap in accordance with applicable regulations; prior to putting into operation, check the complete installation for gastightness; if your appliance is provided with explosion hatches on its top and/or bottom, you must make sure that they cannot be blocked and check whether they fit well onto the sealing surface, prior to building in the appliance; 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; replace broken or torn glass panes.

!Caution

In case of broken or torn glass panes, the appliance may not be used.

3.4 Principle of ignition cycle

Below you will find a brief description of how this appliance is ignited.

The appliance is off and will be switched on by means of the remote control. 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 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%.

If applicable, 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 its 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.

5.9 Flue gas discharge /combustion air supply system at appliances with a closed combustion

5.9.1 General

The appliance's type of discharge system is stated in Appendix 2, Table 2.

The appliance is connected to a combined flue gas discharge/combustion air supply system, hereafter referred to as the concentric system.

The passage to the outside can be made with both a wall terminal and roof terminal.

If necessary, you can also use an existing chimney (see section 5.9.4).

!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;

• For connecting to an existing chimney you should only use the chimney kit supplied by DRU.

• 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.

5.9.2 Construction of the concentric system

Depending on the construction of the concentric system the appliance will have to be further adjusted with possibly a restrictor slide or air inlet guide.

See Tables 4 and 6 for determining the correct adjustment and section 5.9, '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 discharge.

When using a wall terminal the following applies:

• The total vertical pipe length, when using a wall terminal, may have a maximum length that you can find 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 you can find in Appendix 2, Table 4 (without wall terminal; see Appendix 3, Fig. 5).

When using a roof terminal 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;

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) If you end up in a box with a letter, the concentric system chosen by you is permissible;

7) Use Table 6 to determine how the appliance should be adjusted.

INSTALL AT I ON M AN U A L

!Caution

5.9.3 Placing the concentric system

• Maintain a distance of at least 50 mm between the outside of the concentric system and the walls and/or the ceiling. 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;

• The rosette of the wall terminal is too small to seal the opening when passing through combustible material.

That is why you should first apply a sufficiently large heat-resistant intermediate sheet 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:

Build the system up from (the flue spigot of) the appliance.

Connect the concentric pipe pieces and, if necessary, the bend(s).

On each connection, apply a clip binding with silicon sealing ring.

Use a self-tapping screw to fix the clip binding to the pipe on locations that cannot be reached after installation.

Apply sufficient wall brackets, so that the weight of the pipes does not rest on the appliance.

Determine the remaining length for the wall or roof terminal and cut it to size, make sure the correct insertion length is maintained.

Place the wall terminal with the (groove/folded) seam at the top;

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.

5.9.4 Connection to an existing chimney

It is possible to connect the appliance to an existing chimney.

A flexible SS pipe is placed in the chimney with a fitting diameter at the flue gas discharge pipe, for the discharge of flue gases. The surrounding space is used to supply combustion air.

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 you can find 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.

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 a 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.

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:

Place the two penlite batteries (AA) in the battery holder of the remote control.

Make sure the voltage of the atmospheric fire is not switched off for longer than 5 minutes.

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.

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.

As soon as logging on is finished, the start screen will appear

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)).

Ø

Ø

!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:

Connect the 0-3VDC signal to the connector, to which a black and yellow wire are connected (see appendix 3, fig.

36 (D)).

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.

6.2.2 Wireless

The wireless connection is divided into 2 types:

• 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:

Using the remote control, test whether the location where you want to place the communication module is within the receiver's range.

Place the remote control on this location and test the reception sensitivity (RSSI).

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.

Connect the communication module by means of an RJ45 plug, according to the instructions in the manual that is supplied with this module.

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

If the fire is operated via a tablet using the application (iOS or Android), a communication module is required. This module can be ordered from DRU.
