3.1.5 Fuels
Only use recommended fuels. The appliance can be damaged by burning Petroleum Co, liquid fuels or general
rubbish and this will invalidate your warranty and risk personal safety.
The appliance MUSTNOT be used as an
incinerator.
4.0 Installa�on Informa�on
4.1 Chimney
The chimney height and the posi�on of the chimney terminal should conform to
Building Regula�ons
. Flue
heights should be high enough to ensure sufficient draught to clear the products of combus�on, minimum
height 4.5 meters from the top of the appliance. Check that the chimney is in good condi�on, dry, free from
cracks and obstruc�ons. The diameter of the flue should not be less than 125mm and not more than 200mm. If
any of these requirements are not met, the chimney should be lined by a suitable method. The chimney must
be swept before connec�on to the stove.
Where the chimney is believed to have previously served an open fire installa�on, it is possible that the higher
flue gas temperature from the stove may loosen deposits that were previously firmly adhered, with the
consequent risk of flue blockage. It is therefore recommended that the chimney be swept a second �me within
a month of regular use a�er installa�on.
If you have any doubts about the suitability of your chimney, consult your local dealer/stockist or chimney
specialist. If there is no exis�ng chimney then either a solid fuel compa�ble prefabricated block chimney or a
twin-walled insulated stainless steel flue to BS 1856-1 can be used. These chimneys must be fi�ed in accordance
with the manufacturer’s instruc�ons and also please refer to the current issues of Bri�sh Standards BS EN
15287-1:2007 for design, installa�on and commissioning of chimneys.
4.2 Ventilation / Free Air Requirement
Air requirement equivalent area. Building regula�ons Document J, advises that an air supply ,permanently open
vents, should be installed for appliances:
If design air permeability >5.0m³/(h.m²) then 550mm²/kW of appliance rated output above 5kW
or
If design air permeability <5.0m³/(h.m²) then 550mm²/kW of appliance rated output.
Equivalent air is as measured according to the method in BS EN13141-1:2004
It is unlikely that a dwelling constructed prior to 2008 will have an air permeability of <5.0m³/(h.m²) at 50pa
unless extensive measures have been taken to improve air-�ghtness.
4.3 Flue Draught
A flue draught of minimum 1.2mm to a maximum 2.5mm water gauge (12 to 25 Pascals) is required for
sa�sfactory appliance performance. The flue draught should be checked under fire at high output and, if it
exceeds the recommended maximum, a draught stabiliser must be fi�ed so that the rate of burning can be
controlled to prevent over-firing.
4.4 Connec�on to the Chimney
This appliance is
not
suitable for use in a shared flue. This appliance requires a direct flue connec�on to the
spigot. If prac�cal, an exis�ng fireplace opening can be bricked up or sealed with a register plate and a short
length of flue pipe of a minimum 125mm internal diameter may then be used to connect the stove to the
register plate in the chimney. This flue pipe should conform to Building Regula�ons. The stove must be insulated
and properly fi�ed into the fireplace opening by back filling with 6:1 ra�o vermiculite & cement mixture using
minimal water through the top of the fireplace or flue spigot opening. The surface should be finished using 1:1:8
mix of cement, lime and sand. The connec�ng pipe is fi�ed with the spigot pushed up from
inside
the stove and
rotated onto its keyhole slots to join to the pipe. Ensure that the pipe end is no closer than 76mm to the side or
rear chimney walls.
