5.7Fluegasdischargesysteminapplianceswithopencombustion
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.
5.7.1General
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.

English
INSTALLATION MANUAL
!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.
5.7.2Connectionoffluegasdischargesystem (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.
5.8Fluegasdischarge/combustionairsupplysysteminapplianceswithclosed
combustion
5.8.1General
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.
5.8.2Constructionoftheconcentricsystem
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.

English
INSTALLATION MANUAL
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 wallterminal, 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).
!Tip
In the horizontal section, 1 bend of 90° may be included. This bend counts for 2 metres. This means that the
maximum allowed length is reduced by 2 metres. A 45° bend counts for 1 metre.
When using a roofterminal, 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
5.8.3Placingtheconcentricsystem
!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
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
Attach the wall terminal from the outside by means of four screws.
