kit, Xpelair Cat. ref. DXBDG. Do not install these fans in a panel which is more than
46mm thick.
• To prevent a possible hazardous situation from water ingress, an appropriate
condensation trap must be fitted as close as possible to the fan in all situations
where any section of the duct work is positioned higher than the fan itself.
Where to locate the fan
• Locate it as high as possible.
• At least 110mm from the edges of the mounting surface to the centre of the hole.
• As far away as possible from and opposite to the main source of air replacement to
ensure airflow across the room (e.g. opposite the internal doorway).
• Near the source of steam or odours.
• Not where ambient temperatures are likely to exceed 50°C.
• If installed in a kitchen fans must not be mounted immediately above a cooker
hob, or eye level grill.
• If installing in a room containing a fuel burning device which has a non-
balanced flue, it is the installer's responsibility to ensure that there is enough
replacement air to prevent fumes being drawn down the flue when the fan is
operating up to maximum extract.
Refer to Building Regulations for specific requirements.
• Exhaust air must not be discharged into aflue used for exhausting of fumes
from appliances supplied with energy other than electric. Requirements of all
authorities concerned must be observed for exhaust air discharge and intake
flow rates.
• When intended for use in possible chemical corrosive atmospheres, consult
out Technical Service Department. (For overseas markets contact your local
Xpelair distributor).
