Ventilation - Technical Appendix
3. Ventilation
3.1 Many older buildings are sufficiently ventilated by natural
leakage of air to provide suitable air supply for an appliance
of 5kW output or less.
Modern building techniques have reduced the amount of air
that leaks in or out of a house. A modern construction with
an air tightness of less than 5m3 per hour per m2 requires
an air vent for ALL solid fuel appliances including those with
a rated heat output of less than 5kW.
NOTE: The air leakage of a modern house is tested at the
completion of construction and a certificate issued confirming
this.
3.2 This appliance requires a constant supply of air to maintain
proper combustion and effective flue performance.
3.3 An inadequate air supply can result in poor combustion and
smoke entering the room which is potentially dangerous.
3.4 This supply of air can come from either:
— Purpose provided ventilation.
— Some Stovax appliances can also be fitted with an
optional outdoor air kit which allows air to be drawn in
from the outside.
3.5 The amount of air required must comply with local building
regulations and the rules in force.
3.6 If spillage is detected during commissioning then there may
be insufficient natural ventilation and an additional air supply
will be necessary.
3.7 Permanent air vents should be non-adjustable and
positioned where they are unlikely to be become blocked.
3.8 If vents open into adjoining rooms or spaces there must be
an air vent of at least the same size direct to the outside.
3.9 Site the vents where cold draught is unlikely to cause
discomfort. This can be avoided by placing vents near
ceilings or close to the appliance (see diagram).
3.10 Extractor fans or cooker hoods must not be placed in the
same room or space as this can cause the appliance to emit
fumes into the room.=
3.11 Increase air supply provisions where a room contains
multiple appliances.
3.12 If any checks reveal problems do not proceed with the
fitting of the appliance until they have been rectified.
4. Minimum Dimensions - Hearth
4.1 These appliances can stand on a superficial hearth which is
a minimum of 12mm thick, see Diagram 1 Page 16.
This is also referred to as a Floor Protector Plate or Floor
Protector.
As this appliance can be installed in an elevated setting it is
recommended to increase the 225mm hearth depth to safely
contain any falling logs or embers. The higher the appliance
is installed the deeper the hearth should be to protect the
floor.
4.2 The building must have a suitable load-bearing capacity for
the hearth and appliance. Consult a structural engineer for
advice before proceeding.
4.3 When fitting into an existing hearth check that the appliance
complies with current construction regulations and is at least
the minimum sizes shown.
4.4 If there is no existing fireplace or chimney it is possible to
construct a suitable non-combustible housing and hearth
setting. The flue must be installed in accordance with all
local and national regulations and current rules in force.
4.5 Check if adding a new chimney to your property requires
planning permission.
4.6 Some houses are built using a timber frame construction
with high levels of thermal insulation. Isolate the appliance
from combustible materials, and provide sufficient ventilation
to maintain the heating efficiency.
