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 a flue used for exhau sting 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.
