3.1 Ducting Guidelines
Please refer to the dwelling's design drawings for the proposed ducting
layout.
Two 220mm x 90mm sockets are provided for connecting the ducting.
Domus rigid ductwork should be securely connected to the sockets
using DDSEAL acrylic sealant; failure to do this will cause unnecessary
air leakage and impair performance. Using the arrows moulded into
the body of the CMX-S appliance as a guide, ensure that the
direction of airflow is from the 'wet rooms' to the outside.
Ducting attached to the appliance must be supported adjacent to
the appliance using 922 Support clips. This is important for major
maintenance or end of life replacement to ensure that the ducting is
adequately supported if the CMX-S body is removed.
Where ducting passes through unheated areas and voids (e.g. loft
spaces) it must be insulated in order to comply with Approved
Document F of The Building Regulations.
When passing through a fire-stopping wall or fire-compartment wall,
FireBrake intumescent duct connectors should be used in order to
comply with Approved Document B of The Building Regulations.
Alternative proprietary fire-stopping methods may be employed
provided they comply with Approved Document B of The Building
Regulations.
The stale extract air must be expelled to the exterior of the property.
If expelled through a wall, a 905 airbrick should be fitted. If expelled
through the roof a 4411 universal roof terminal should be fitted or a
proprietary roof terminal designed for mechanical ventilation with a free
area of at least 15175mm².
Further details regarding installation can be found in the 2010 Domestic
Ventilation Compliance Guide.
3.1.1 Rigid Ducting
Install using the least number of fittings to minimise resistance to
airflow. All duct runs should be as short and as straight as possible for
maximum performance.
3.1.2 Semi-Rigid (Radial) Ducting
