3.2 INSTALLATION - OVERVIEW
CONVECTION
Spartherm wood fires are convection fires with “central
heating” capabilities. Convection means that there is a natural
circulation of air, which ensures that the heat is distributed
more evenly throughout the entire room or dwelling. The cold
air is drawn in at the base of the fire, and then moved up
through the convection channel, which runs along the fire’s
combustion chamber. The heated air pours out at the top of
the fire via the duct spigots (4 off).
The hot air can then be completely or partially distributed to
other areas of the same room or alternative rooms via flexible
aluminium ducting or vents within the cavity walls.
The total convection air venting open surface area must be at
least 880 cm
2
distributed between the aluminium ducted vents
and cavity vents. In addition, two ‘intake’ vents of at least 90 x
300 mm or an open surface area of at least 540 cm
2
must be
provided into the cavity surrounding the fireplace to provide
adequate air for convection. This is in addition to the
requirements for combustion air as outlined in the planning
section.
The intake vent(s) should be placed as low as possible in the
cavity ideally below 300 mm from the floor. They should be no
more than 300mm from the bottom of the appliance. Two
vents (one each side) is preferential over one.
