CAUTION
The chimney should be swept at least twice by a
competent and approved person. All chimney joints
should be inspected during cleaning.
FRESH AIR SUPPLY
A solid fuel appliance requires a continuous supply of
air to support combustion. If another air using appli-
ance such as extractor hood or clothes dryer is
installed in the same or an adjacent room, the venti-
lation supply will need to be increased to ensure
there is adequate air for ventilation and combustion
when all appliances are in operation.
In houses equipped with mechanical ventilation an
external air connection must be installed to provide
adequate air for combustion.
Properly installed solid fuel unit will give even the
most efficient houses a pleasant and natural ventila-
tion.
DRAUGHT CONDITIONS
If smoke spillage occurs when the firedoor is
opened, it is probably due to poor chimney draught.
This type of stove requires at least 15 Pa. of chimney
draught to achieve satisfactory combustion and
smoke spillage prevention. However, in cases
where the stove door is opened too quickly you
could expect that slight smoke spillage may occur.
Only open the door when the stoves has extin-
guished or the fire is a bed of glowing embers,
If you have any doubts, you may want to have your
installer measure the draught in the chimney.
The chimney’s draught is the resulting effect within
the flue caused by the difference in temperature
within the flue and the cooler temperature outside.
Other factors that can influence the level of draught
include the length of the flue, insulation of the chim-
ney, adverse weather conditions, tall buildings or
trees nearby the flue terminal.
VENTILATION AND COMBUSTION AIR
REQUIREMENTS
It is essential that there is an adequately sized air
vent in the room in which the product is installed.
When calculating combustion air requirements for
this appliance use the following: 550mm2per each
kW of rated output should be provided, where a flue
draught stabiliser is used the total free area shall be
increased by 300mm2for each kW of rated output.
If there is another appliance using air fitted in the

CONNECTING TO A STEEL CHIMNEY
If your installation involves taking the chimney
straight up and through the ceiling, you must comply
with National, Local and Building Regulations or flue
manufacturers instructions concerning clearances to
combustible materials such as walls, floor joists and
ceilings. The joint between the stove flue collar and
the stove pipe must also be sealed using the fire
cement. It is important that the insulated flue system
is properly supported both at ceiling level and at roof
level.
THE STOVE MUST NOT BEAR THE WEIGHT OF
THE CHIMNEY SYSTEM (see chimney manufactur-
er’s instructions).
Excessive weight on the stove will inhibit expansion
and could lead to damage of the stove top. Damage
caused to the stove in this way would not be covered
by the Manufacturers Warranty.
IN THE EVENT THAT A CHIMNEY FIRE OCCURS
RESULTING FROM FAULTY OPERATION OR
PROLONGED USE OF DAMP WOOD FUEL,
CLOSE THE AIR VENTS COMPLETELY AND
CONTACT YOUR LOCAL FIRE DEPARTMENT
IMMEDIATELY.
