PRE-INSTALLATION CHECKS
3.1 This appliance requires ventilation to supply combustion air.
Any room containing the appliance must have a permanent
air vent opening with a total free area of at least 550mm
2
per kW of appliance rated output above 5kW.
3.2 Increase air supply provisions where a room contains
multiple appliances.
3.3 If vents open into adjoining rooms or spaces there must be
an air vent of at least the same size direct to the outside.
3.4 Permanent air vents should be non-adjustable and
positioned where they are unlikely to become blocked.
3.5 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 opposite.
3.6 If the appliance has a nominal input not exceeding 5.0 kW
it therefore does not normally require any additional
permanent ventilation. If, however, spillage is detected
when commissioning the fire, there may be insufficient
natural ventilation and additional ventilation may be
required.
