Final ventilation connections
Provision of insulation to ducts and pipes, in accordance with the standards specified in BS 5422:2009,
should adequately limit heat loss or heat gain, as appropriate.
Any exhaust ductwork passing through a heated space must be suitably insulated to avoid condensation
and/or heat gain.
Any supply or extract ductwork passing through an unheated space must be suitably insulated to avoid
condensation and/or heat loss or heat gain. A ceiling void is not considered an unheated space as it is
directly above a heated space.
Connect the Insulated flexible ducts to the Heat Pump using the metal transition pieces provided with the unit.
To avoid cooking odours entering the Heat Pump, a distance of 1.5m must be maintained between the
kitchen extractor fan to the kitchen ceiling valve of the extract ductwork. When cooking, always use the
kitchen extractor fan.
Before connecting the Insulated flexible ducts to the top
of the Heat Pump take stock of what would be the most
practical orientation to route the pipes in your installation.
There are 2 connection options for the ‘Air In’; top left &
side and 1 option for the ‘Air Out’; top right. Once the
Intake option is chosen, remove the plastic dust covers
from the Heat Pump.
The top connection is the most common.
If the other connections are used, the plastic caps must be
removed and used to plug the top connection. A flat head
screwdriver can be used to remove the caps. There is the
option to use the extra ‘Air In’ side connection alongside
the top connection. A ceiling valve can be connected
directly to the side connection (via a suitable transition
piece) as the extract valve for the room the Heat Pump is
installed in. This would negate the need for an additional
ductwork connection in the ceiling above the unit, where
space can sometimes be a premium.
If this option is chosen, the minimum clearance value for
the lefthand side of the unit MUST increase to 500mm.
