certain circumstances a purpose provided air vent may be required such as insufficient natural
ventilation or date of building construction etc.
Purpose provided air vents must be of the correct size and be non closable and unrestricted, refer to
building regulation & any other rules in force.
Do not use any extractor fans or any other similar devices in the room into which the stove is installed.
Air inlet vents should be positioned in the room at locations to avoid them becoming blocked. If the air
supply is inadequate the chimney draft may be too weak, with the possible result that the stove will not
burn properly leading to a potentially dangerous situation. Smoke spillage may also occur during the
refueling process. When determining the ventilation requirements account will need to be made for
any other combustion devices in the room.
Fresh air supply:
Refer to building regulations & any other rules in force, including BS 8303 and BS EN
15287-1:2007.
(Bela Vista & Grande Vista, nominal heat output 7.5kw).
A wood-burning stove requires air for combustion and therefore you may need to install additional
ventilation to the room. An adequate air supply for ventilation & combustion is required to the room
into which the stove is installed. As this stove is CE tested to 7.5KW nominal heat output. (Refer to
Building Regulations Document J) a purpose provided air vent
is required
with a minimum free flow
area of 1375mm.

2.8 Draft conditions
If smoke spillage occurs when the fire door is opened, it is probably due to poor chimney draft. This
type of stove requires at least
12 pa
of chimney draft to achieve satisfactory combustion and smoke
spillage prevention. However, in cases where the stove door is opened too vigorously you could expect
that slight smoke spillage may occur.
If you have any doubts, you may want to have your installer measure the draft in the chimney.
