2.4. Assembly of flue spigot and blanking
plates
The stove is supplied with a connection flue spigot with
an inner diameter of 125 mm or an outer diameter of
139 mm.
-
Remove the internal baffle (rep. 17, page 13).
-
Fit the sealing rope in the groove and attach the flue
spigot (rep. 26, page 13) using the three bolts and
washers supplied.
-
Check that the two blanking plates are fixed to the
back wall (rep. 25 & 35, page 13).
-
Replace the internal baffle.
-
Remove the internal baffle (rep. 17, page 13) and the
rear heat shield (rep. 16, page 13).
-
Fix the sealing rope in the groove on the rear and fit
the flue spigot, ensuring there is a good seal.
-
Fix the sealing rope in the groove on the top and fit the
two blanking plates, ensuring there is a good seal.
-
Replace the internal baffle.
-
Remove the cut-out in the rear heat shield and re-fit.
2.5. Chimney connector
The connection to flue must be carried out
according to local building regulations.
-
The appliance 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. If there is no other solution, the
reduction can not be more than one diameter lower
than the flue spigot and be situated as distant as
possible from the flue connection of the appliance.

-
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 flue must not be supported by the stove.
-
Consult a chimney specialist for advice on suitable
flue systems for solid fuel appliances.
-
The connection can be either vertical or horizontal. For
horizontal connections, avoid right angle bends.
-
The join between the connection pipe and the
stovepipe, and the flue, must be leak tight.
-
For the premises equipped with a mechanical
controlled ventilation, the airtightness has to prevent
the exhauster drawing out the smokes from the
exhaust gas pipe.
-
The connection pipe and any draught stabiliser must
have access for cleaning.
-
The spigot should be connected to a minimum of
125 mm flue system and in that case the appliance is
capable of burning untreated wood and recommended
solid fuels.
