Location of hearth or appliance
Where the hearth abuts a wall and the appliance is not more than
50 mm from the wall
Where the hearth abuts a wall and the appliance is more than 50
mm but not more than 300 mm from the wall
Where the hearth does not abut a wall and is no more than 150 mm
from the wall (See Note 1)
Note: 1. There is no requirement for protection of the wall where X is more than 150 mm.
Will access from a single side be sufficient for most boilers? Indeed which side, this may vary from models to model.

CHIMNEY

The chimney is essential for the proper operation of the boiler and it must fulfil with the following requirements or meeting local national
requirements
• The smoke duct must be free of blockages. Mounting predominantly in the vertical plane. Avoid bends and deviations in relation to the
vertical axis greater than 45% .
• At least, 5 meters of chimney will be installed to guarantee a good draw, trying to use double-wall pipes to optimise the hot smoke duct
from the boiler and avoid any condensation inside. In the external exits it is recommended to exceed the ridges or the highest point of
the roof in half a meter at least.
• The interior section must be perfectly circular: rectangular or cross-sections must have rounded corners with a radius of not less than
20 mm.
• The interior section must be constant, free and independent.
• In order to avoid smoke flow returns or turbulences that may cause a blockage or reduce the correct smoke outlet, the connections will
be made by qualified staff, by following the steps on the safety rules point.
• The average draft of the chimney for the nominal power is ±12Pa when using wood pellets.
• To join the smoke ducts it is necessary to use non-flammable materials, resistant to the combustion products and their possible
condensations.
• It is forbidden to use fibre cement or metallic flexible pipes to connect the boiler to the chimney.
• It is important to install the necessary elements between the smoke duct and the boiler smoke outlet duct in order to avoid the support
of the duct on the boiler.
• Smoke ducts must not pass through the rooms where it is forbidden the installation of combustion equipments.
• The installation of the smoke ducts must be made so that they are airtight to smoke during operation and that the formation of any
condensation is limited to avoid that it flows towards the equipment.
• It is not recommended to install in horizontals sections. The maximum horizontal section allowed is 1 m (with an incline of 3%)
• In the case of installations where the flue exit through a ceiling or walls it should be in the same plane with respect to the equipment
smoke exit, the change of direction must be made by open bends not higher than 45º.
• In any case, smoke ducts must be airtight to combustion products and to the condensations and they must also be thermal insulated if
they pass outside the installation room.
• It is forbidden to install flues with a downward slope.
• The smoke duct must allow the cleaning of the soot or be easily accessible.
• The duct section must be constant.
• It is forbidden to pass any others air ducts or pipes inside the smoke channels. It is not allowed to fit devices to control manually the
draw in equipments with a forced draw.
