Air requirements
Proper air supply must be insured
to the room into which the stove
is to be installed. A permanent
vent opening with a minimum free
area of 55 cm
²
must be present and
care should be taken to ensure
that this vent cannot be blocked.
Under no circumstances should
there be an extracting fan in the
same room as the stove, to avoid
the possibility of combustion
gases being drawn into the room.
If a chimney draft stabilizer is
fitted to the chimney, a larger
vent is required of at least 8.5
cm
²
per Kw of output over 5kw.
The vent must be of a permanently
opened design. The vent must be
dimensionally stable and must not
be prone to collapse. There must
not be a facility to close the
vent. If the vent crosses into a
cavity to the outside on an
external wall it must span the
full span across the cavity and
must be weather resistant to
prevent the ingress of moisture.
The vent must not be located at a
position in the room that will
result in an air current
traversing through normally
occupied areas of the room.
Care must also be taken to ensure
that the vent cannot be blocked by
object left against the wall
outside or debris like leaf litter
etc.
A larger vent is required if there
is an appliance like an extractor
fan or tumble drier in an
adjoining room. To ascertain if
more venting is required, these
appliances should be operated
together and all external windows
and doors closed to detect
spillage into the room from the
stove.
If the vent crosses into another
internal room, that room should
not be a bedroom, bathroom or room
with a shower and it must not
cross into another internal
separate building for example a
bedsit.
Especially air tight buildings:
If the stove is to be installed
into an especially air tight house
at least 5.5 cm
²
per Kw of stove
output must be installed to ensure
proper operation of the stove.
External Air provision:
This stove has the provisions made
for connection to an external air
system for buildings where
mechanical heat ventilation is
installed. There are 3 positions
for connection to an external air
pipe, at the centre rear facing
backward and each side of the
stove at the rear facing away from
the stove.
