Boiler room
Th e boiler room must be built in accordance with applicable
building regulations.
Provision for good air supply. Th e boiler room's air intake must
be as large as the fl ue.

Chimney

VEDEX 3300 has a vertical fl ue pipe connection with an ex-
ternal diameter of 133mm. A vertical fl ue pipe is supplied as
standard.
Th e fl ue diameter should be 150mm in accordance with the
Building Regulations.
Th e fl ue should be dimensioned in accordance with the
Building Regulations and EN 13384-1 to facilitate correct
functioning of the combustion system.
Th e minimum chimney draught for satisfactory wood fi ring is
15 Pa.
Th e fl ue needs to be inspected and approved before installa-
tion.
If in doubt reference should be made to 'Th e Building
Regulations 2000 Approved Document J Combustion
Appliances and Fuel Storage Systems 2010 Edition' or the
building control department of your local council.
Material Area
Steel pipe Ø 150 mm
Brick 150 x 150 mm
Many older boilers have the fl ue duct located at the bottom
and have been connected to the chimney near to the fl oor. If
the new boiler is to be connected higher up on the chimney
the lower, non-active, part of the chimney pipe should be fi lled
with sand or similar.
Carbon Monoxide Detectors
It is mandatory to fi t a Carbon Monoxide alarm within the
room whenever a new or replacement solid fuel appliance
is installed in a dwelling. Th is alarm must be a permanently
installed type, rather than a portable type, and should incor-
porate self-test and audible alert if the battery or detector cell
develop a fault. Siting of the alarm must meet the following
criteria:
a) on the ceiling at least 300mm from any wall or, if it is lo-
cated on a wall, as high up as possible (above any doors and
windows) but not within 150mm of the ceiling; and
b) between 1m and 3m horizontally from the appliance.

NOTE!
Ensure that sweeping can be carried out in accord-
ance with the applicable regulations.
If in doubt, contact a chimney sweep.

Assembly

VEDEX 3300 has inlets for primary air at the front and sec-
ondary air on the sides of the boiler. Th erefore, always leave a
space of at least a metre from combustible material. In unfa-
vourable cases "puff s" from combustion can discharge sparks.

Turbulators

Six turbulators are supplied with the boiler. Th ese are located
in the ducts in the boiler's convection part as illustrated. Th e
turbulators aff ect the turbulence of the fl ue gases, which means
that a greater amount of energy is transferred to the boiler wa-
ter. Th e temperature in certain chimneys may become so low
that there may be a risk of condensation build-up in the smoke
duct. To increase the temperature in the chimney the turbu-
lators can be removed, one at a time as illustrated. For each
turbulator that is removed, the fl ue gas temperature rises from
the boiler by 15 – 25 °C.
Remove the turbulators in number order until the fl ue gas
temperature in the chimney is correct.
