5.2 Connection
5.2.1 Gas connection
Place a gas tap in the gas pipe in accordance with the applicable regulations.
!Caution
•
Make sure there is no dirt in the gas pipes and connections.
•
No soldering may take place at the flexible gas hose(s), as this could cause leaks.
The following requirements apply to the gas connection:
•
use a gas pipe with the correct dimensions, so that no pressure loss can occur;
•
the gas tap must be approved (in the EU this will be the CE mark);
•
you should always be able to reach the gas tap.
5.2.2 Electric connection
In case of a 230 Volt electrical connection, provide proper grounding, if applicable.
Place this electrical connection away from the appliance, as low as possible in the chmney breast.
This has to do with the temperature development in the chimney breast.
If possible, place the receiver after any building work has been completed.
If this is not possible:
!Caution
Protect the receiver against dust and moisture created during the building process!
5.3 Placing the appliance
!Caution
•
Unless stated otherwise: always place the appliance with a minimum distance of 500 mm from combustible
objects or materials;
•
Place the discharge pipes in such a way that situations with risk of fire can never occur;
•
Always place the appliance in front of a wall of non combustible and heat-resistant material;
•
Always maintain a minimum distance between appliance and back wall, if indicated in the dimensional
drawing (Appendix 3, fig. 2);
•
Take sufficient measures to prevent high temperatures of a possible wall behind the chimney breast,
including the materials and/or objects that are behind the wall;
•
Do not cover the appliance and/or do not wrap it in an insulation blanket or any other material;
•
Make sure that the appliance to be installed has a stable position. Attach the appliance, if applicable, to the
wall using the wall brackets and/or fasten the extending legs with self-tapping screws.
!Caution
When installing an appliance that has to be built in, take the following into account:
The minimum construction dimensions according to Appendix 3, fig. 1 and 2.
Ø
Provide a gas connection at the location. For details (see section 5.2).
Ø
Make a passage for the flue gas discharge system or the concentric system with the following diameters; for
details, see section 5.7 or 5.8:
•
the pipe di10 mm for a passage through non combustible material;
•
the pipe di100 mm for a passage through combustible material.
!Caution
Starting at section 5.9, you will find additional instructions that are specifically needed for the installation of your
appliance.
5.4 Placing a built in appliance
(if applicable)
Not all DRU built in appliances are supplied with a control hatch. If not included in the delivery, this control hatch
is available separately. In case of appliances with closed combustion (type C11/C31) we always recommend using
the Dru control hatch. In case of appliances with open combustion (type B
11 AS/BS
), a control hatch is not required.
In this section we assume an application with control hatch.
!Caution
If you do not use a recommended Dru control hatch, please strictly observe the safeguards and necessary
instructions stated in chapters 5.4 to 5.6.
If you are not using the control hatch, please take the following into account as well:
•
the accessibility of components that are normally placed in the control hatch;
•
the maximum temperature of these components (maximum 55 °C).
The gas control is mounted under the appliance, at the burner mounting plate. It must be taken out and placed in
the control hatch at a later time. For placing the gas control in the control hatch, see section 5.6.
