5.7 Flue gas discharge system in appliances with open combustion

For connection to an existing chimney without a discharge pipe or flexible SS discharge – only allowed in Great
Britain – the instructions provided in the separately supplied booklet 'Fitting into a conventional class 1 chimney'
apply. In addition to the installation instructions, this booklet also contains supplementary tests. In this situation
we recommend using a stainless steel flexible discharge pipe over the complete length, with a draught increasing
hood.

5.7.1 General

The connection dimensions and the minimum length of the discharge system are indicated in Annex 2, table 2.
The appliance should be connected in accordance with the applicable national, local and constructional
(installation) regulations. You should only install the appliance in a well ventilated room which complies with the
applicable national, local and constructional (installation) regulations, in order to guarantee sufficient air supply.

!Caution

- When the appliance is installed in a house with a mechanical air extraction system and/or an open kitchen
with cooker hood, you will need a permanent ventilation hole in the room where the appliance is installed;
please observe the gas installation regulations and the local regulations for dimensions and other required
provisions.

- No ventilation of the chimney breast is required in case of an existing chimney with a masonry fireplace that
is sufficiently able to absorb the heat. Therefore the ventilation hole in the chimney breast does not apply to
the class 1 chimney in the UK.

UK

English

INSTALLATION MANUAL

5.7.2 Connection of flue gas discharge system (if a class 1 chimney is not applicable)

For connection to an existing chimney, a flexible stainless steel discharge pipe is required over the complete
length for the discharge of the flue gases, unless indicated otherwise. A draught increasing hood is recommended
here.

!Caution

- Prevent dirt from an existing chimney from entering the flue gas discharge.

- Prevent false draught by carefully closing the space between the existing chimney and the discharge
material.

- Bends of more than 45 degrees are not allowed in the flue gas discharge system, unless indicated otherwise.

- Maintain a distance of at least 50 mm between the outside of the concentric system and the walls and/or
ceiling. If the system is built in (for instance) a cove, it should be made with non combustible material all
around it;

- Use heat-resistant insulation material when passing through combustible material.

- Use a flue gas discharge system with the correct diameter, and which is provided with the CE mark.

!Caution

Some heat-resistant insulation materials contain volatile components that will spread an unpleasant smell during
a longer period; these are not suitable.

Place the flue gas discharge system as follows:

Ø

Connect the pipe pieces or flexible SS discharge.

!Caution

- Make sure that the right insertion length is maintained.

- Secure the connections on locations that are impossible to reach after installation by means of self-tapping
screws.

5.8 Flue gas discharge / combustion air supply system in appliances with closed
combustion

5.8.1 General

The appliance's type of discharge system is stated in Appendix 2, Table 2.
The appliance will be connected to a combined flue gas discharge / combustion air supply system, hereafter to be
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 5.8.4).

!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;

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

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 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 '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. 4).

UK

English

INSTALLATION MANUAL

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

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
ceiling. If the system is built in (for instance) a cove, it should be made with non combustible 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 a glue plate for a flat roof or with a universally adaptable tile for a sloping
roof.

!Caution

Some heat-resistant insulation materials contain volatile components that will spread an unpleasant smell during
a longer period; 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

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

Ø

Attach the wall terminal from the outside by means of four screws.

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;

!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.

INSTALLATION MANUAL

6.3 Alternative operation

Appliances made with an electronic ignition and radio remote control can be connected to an alternative external
control system (e.g. Domotics). For this purpose, there are 4 connection points at the side of the receiver (see
Appendix 3, fig. 44). For connecting an external control unit, you will need a “Domotics connection cable for
GV60”. Consult DRU's service website.

The following contacts are possible:

- Ignition: connect both contacts 1 + 3, for one second (if there is a 2nd thermocouple, the appliance should
burn at full power for at least 20 sec. before the required position can be chosen).

- Flame high(er): briefly close contact 1 once per step, or 12 seconds for the highest position.

- Flame low(er) until switch-off (pilot flame remains on): briefly close contact 3 once per step, or 12 seconds for
the lowest position.

- Completely switching off the appliance (pilot flame included): close all three contacts 1 + 2 + 3, for one
second.

The appliance will always continue to respond to the radio remote control supplied with it. The external control
system is able to use one of the two modes of this remote control.

1. Manual mode
This mode of the remote control is passive and will not take any action unless it is operated. The external control
system is able to control the functions for high/low position, ignition and switching off.

!Tip

If the external control system has an intelligent clock function and/or thermostat function, the remote control
supplied with the appliance should have the manual mode in order to prevent interruption of these functions.

2. Clock/thermostat mode
This mode of the remote control is active and will be responsible for the clock function and thermostat function.
The external control system is able to control the functions for high/low position, ignition and switching off.

!Tip

- If the appliance is switched off (the pilot flame included) manually or by one of the safeguards, ignition of the
appliance will be blocked for a period of 3 minutes for reasons of safety.

- If it is no longer possible to operate the appliance with the external control system, you must switch it off and
then switch it on again with the supplied remote control.

7. Final inspection

In order to check whether the appliance is working properly and safely, you must perform the following
inspections before the appliance is used.

7.1 Gastightness

!Caution

All connections must be gastight. Check the connections for gastightness.
The gas control can be subjected to a maximum pressure of 50 mbar.

7.2 Gas pressure/line-pressure

The burner pressure is set at the factory; see data plate.

!Caution

The line-pressure in house installations must be checked, because it can be wrong.

Ø

Check the line-pressure; see Appendix 3, fig. 41 for the measuring nipple on the gas control.

Ø

Contact the gas company if the line-pressure is not correct.

INSTALLATION MANUAL

7.3 Ignition pilot and main burner

For igniting the pilot and main burner, see the User Manual, chapter 4, section 4.2, Remote control.

7.3.1 First ignition of the appliance after installation or adjustments

!Caution

After installation, or after work has been performed, you should ignite the appliance for the first time without the
glass window. If necessary, bleed the gas pipe.

Follow the procedure described below:

Ø

If required, remove the glass window;

Ø

Start the ignition procedure according to chapter 4 in the User Manual;

Ø

If the pilot flame does not ignite:

- repeat the ignition procedure until the pilot burner ignites;

- consult the malfunction search diagram (Appendix 1) if this does not happen after a few attempts;

Ø

After igniting the pilot flame, the main burner will ignite during the ignition procedure;

Ø

Check whether the main burner continues to burn;

Ø

If the main burner does not continue to burn:

- repeat the ignition procedure until the main burner continues to burn

- consult the malfunction search diagram (Appendix 1) if this does not happen after a few attempts;

Ø

Switch off the appliance;

Ø

Then mount the glass window as described in chapter 5.10;

Ø

Repeat the ignition procedure a few times and perform the checks described in chapter 7.3.2;

Ø

From now on, the pilot flame should ignite smoothly.

!Tip

When checking whether the main burner continues to burn, it is possible that it still switches off after 22 seconds.
This happens because the appliance is equipped with a second thermocouple and the glass window has not been
placed. In this case you may presume that the main burner will continue to burn.

!Caution

- During the ignition process, you are not allowed to operate control button B on the gas control manually.

- Always wait 5 minutes after the pilot flame has gone out, before you re-ignite the appliance.

- You are not allowed to turn the pilot flame lower by using the settings on the gas control.

7.3.2 Main burner

!Caution

- The pilot burner 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.

Ø

Check operation of the main burner from a cold condition (pilot flame off):

Ø

After opening the gas valve, the main burner should burn within a few seconds.

!Tip

When the gas valve is opened, the motor will start to run; this is audible.
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
abovementioned requirements.

7.4 Flame picture

The flame picture can only really be assessed when the appliance has been burning for several hours. Volatile
components from paint, materials, etc., which evaporate in the first hours, will affect the flame picture.

!Caution

If the chimney breast has been made of stone-like materials or has a plaster finish, the appliance may only be put
into operation 6 weeks after the chimney breast has been placed, in order to prevent shrinkage cracks.

Ø

Check whether the flame picture is acceptable.

Ø

Consult the malfunction search diagram (Appendix 1) if the flame picture is not acceptable.
