System Illustration
With 204x60mm spigots, the
CMX-MULTI units can support
direct duct runs, without the need
for adaptors or flexible duct fixings.
5.2
Ducting attached to the appliance must be supported adjacent to
the appliance using 522 Support clips. This is important for major
maintenance or end of life replacement to ensure that the ducting is
adequately supported if the CMX-MULTI / CMX-MULTI-H body is
removed.
5.3
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.
5.4
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.
5.5
Alternative proprietary fire-stopping methods may be employed
provided they comply with Approved Document B of The Building
Regulations.
5.6
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.
