If the appliance has to be located in an opening, this
distance must be extended to a minimum clearance
(A) of 550 mm from the pipe or the stove body to any
combustible materials.
Hearth
: The appliance must stand on a fireproof
hearth.
It is possible to provide a hearth made of non
combusible board/sheet material or tiles at least 12
mm thick (C).
Constructional hearths should be constructed of
solid non combustible material at least 125 mm thick
(including the thickness of any non combustible floor
under the hearth).
The hearth must protrude at least 225 mm in front of
the stove and 150 mm each side.
If the hearth is constructed on timber, there must be
a clearance of at least 250 mm from the timber to the
top surface of the hearth. See section J of the Building
regulations.
Do not place any combustible materials in front of the
stove within a distance of 115 cm.
Be aware that the distances given are the minimum
required, however take into consideration that
you need to have sufficient space for cleaning and
maintenance purposes.
Do not place any object or combustible material,
curtains, hangings, etc... within the safety
distances.
2.3. Chimney
Existing flue
: The chimney must comply with
Current Building Regulations. If in doubt, consult your
Dealer or local Building Inspector.
- The flue must be in good condition and must provide
sufficient draught.
- The flue must be suitable for the installation of solid
fuel burning appliances and comply with Current
Building Regulations.
- The flue must be clean. It should be swept to remove
soot and dislodge tar deposits.
- The flue must be well insulated. If the flue inner wall
surfaces are cold, a good thermal draw is impossible
causing condensation problems (tar formation etc) to
occur.
- The flue must not be shared with other appliances.
- The chimney must be at least 4.5 m (15 ft high).
- In case of a flat roof or when the roof gradient is
lower than 15°, the stack must be 1,2 m (4 feet) high
at least.
- If the chimney has any down draught tendency, due
to its position in relation to nearby obstacles, then an
anti-down draught cowl must be installed on the
chimney or the chimney height must be increased.
- If the decompression in the chimney is excessive, a
draught stabiliser must be installed.
Chimney to be built / new flue
: The chimney
must comply with Current Building Regulations. If in
doubt, consult your Dealer or local Building Inspector.
- The appliance must not support the weight of the
flue.
- Consult a chimney specialist for advice on suitable
flue systems for solid fuel appliances.
- It must be distant from any combustible material
(walls, cross members)
- Easy sweeping access must be provided.
2.4 Mounting the flue collar
The stove is supplied with a connection flue spigot with
an inner diameter of 125 mm and an outer diameter of
139 mm.
2.5 Top flue outlet
The stove is set from the factory with a top outlet.
2.6 Rear flue outlet
(
Figure 3)

according to local building regulations.
- The stove must be installed as close as possible to
the chimney.
- The connector pipe must be approved for installation
with combustion products (either 24 ga. black painted
or blued steel or 316 grade 20 ga. Stainless steel or
1 mm vitreous enamelled steel).
- Pipe diameter must not be less than the appliance
spigot diameter. Otherwise the reducing must be
