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 di25 mm for a passage through non combustible material (see Appendix 3, fig. 40).
- The pipe di200 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
Apply sufficient wall brackets, so that the weight of the pipes does not rest on the appliance.
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.
