Cast Tec POLARIS INTEGRA INSET ARCH ECO Installation And Operating Instructions Manual page 14

Polaris Integra Arch Eco Manual Ref No: I17. V2.
An air vent outside the building should not be located less than the dimensions specified
within the Building Regulations and B.S. 8303: Part 1 from any part of any flue terminal.
These air vents must also be satisfactorily fire proofed as per Building Regulations and B.S.
8303: Part 1.
Air vents in internal walls should not communicate with bedrooms, bedsits, toilets,
bathrooms or rooms containing a shower.
Air vents traversing cavity walls should include a continuous duct across the cavity. The
duct should be installed in such a manner as not to impair the weather resistance of the
cavity.
Joints between air vents and outside walls should be sealed to prevent the ingress of
moisture. Existing air vents should be of the correct size and unobstructed for the appliance
in use. If there is an extraction fan fitted in adjacent rooms where this appliance is fitted,
additional air vents may be required to alleviate the possibility of spillage of products of
combustion from the appliance/flue while the fan is in operation. Refer to B.S. 8303 Part 1.
Where such an installation exists, a test for spillage should be made with the fan or fans
and other appliances using air in operation at full rate, (i.e. extraction fans, tumble dryers)
with all external doors and windows closed.
If spillage occurs following the above operation, an additional air vent of sufficient size to
prevent this occurrence should be installed.
PERMANENT AIR VENT EXTRACTOR
The stove requires an adequate air supply in order for it to operate safely and efficiently.
The installer may have fitted a permanent air supply vent into the room in which the stove is
installed to provide combustion and/or ventilation air. This air vent should not under any
circumstances be shut off or sealed.
EXTRACTOR FAN
There must not be an extractor fan fitted in the same room as the stove as this can cause
the stove to emit smoke and fumes into the room.
