If it not possible to include the external air vent in the same room where the stove is installed, the hole can
be made in an adjacent room as long as it is permanently connected by means of a transit hole (15 cm
minimum diameter).
The UNI 10683 Standard FORBIDS the withdrawal of combustion air from garages, combustible
material warehouses, or from businesses with a fire hazard.
Do not connect the external air vent to the stove through piping
.
If there are other heating or
extraction devices inside the room, the air vents must guarantee a sufficient amount of air for
properly operating all the devices.
Only sealed equipment (e.g. C-type gas devices, as defined by the UNI 7129 C standard) or
equipment that does not depressurise the room compared to the outside environment can be housed
- whether existing or newly installed - in the room where the stove is installed.
Extractor fans can cause operating problems to the stove when they are installed in the same room or space
as the device.

Chimney and Flue pipe
The chimney is essential to the efficient operation of a Klover appliance. The chimney should be designed and
constructed according to these instructions, and relevant regulations including Building Regulations Approved
Document J.
Shape and size of chimney: A round chimney of 125mm diameter is recommended. 125mm is also the
minimum diameter which should be used. If the appliance is DEFRA Exempt then it should be connected to a
125mm chimney as standard (assuming that the outlet is not larger than 125mm). If it is not DEFRA Exempt
then a calculation according to BS EN 13384-1:2002 must be completed if it is to be connected to a 125mm
diameter chimney.
The maximum recommended round chimney diameter is 150mm.
Square or rectangular cross-sections must have rounded corners with radius not less than to 20 mm
Rectangular cross-sections must have a maximum ratio of 1.5 between the sides.
The chimney must have a constant, and unobstructed, internal cross section
Under no circumstances should the chimney be of a smaller diameter than the appliance outlet.
Connecting flue pipe: Short runs of single skin flue pipe to connect to the chimney may be run in a (minimum)
diameter of 100mm (as long as this is not smaller than the appliance outlet).
