VEDEX 4000 has inlets for primary and secondary air on
the sides of the boiler. Therefore, always leave a space of
at least a metre from combustible material. In unfavoura-
ble cases “pu󰀨s” from combustion can discharge sparks.
It is mandatory to t a Carbon Monoxide alarm within
the room whenever a new or replacement solid fuel
appliance is installed in a dwelling. This alarm must
be a permanently installed type, rather than a porta-
ble type, and should incorporate self-test and audible
alert if the battery or detector cell develop a fault.
Setting of the alarm must meet the following criteria:
• on the ceiling at least 300mm from any wall or,
if it is located on a wall, as high up as possible
(above any doors and windows) but not within
160mm of the ceiling;
• between 1m and 3m horizontally from the appliance.
Many older boilers have the ue duct located at the
bottom and have been connected to the chimney
near to the 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 lled with sand or sim-
ilar material.
Material Area Min. height
Steel pipe Ø160 mm 5.0 m
Brick 160 x 160 mm 5.0 m
The boiler room must be built in accordance with ap-
plicable building regulations.
Provision for good air supply. The boiler room’s air
intake must be as large as the ue.
Set the boiler while maintaining the minimum distances
to the walls. When installing the unit, pay special atten-
tion to a convenient access to the boiler and chimney
during maintenance, cleaning and servicing.

VEDEX 4000 has a vertical ue pipe connection with
an external diameter of 133mm. A vertical ue pipe is
supplied as standard.
The ue diameter should be 160mm in accordance
with the Building Regulations.
The ue should be dimensioned in accordance with
the Building Regulations and EN 13384-1 to facilitate
correct functioning of the combustion system.
The minimum chimney draught for satisfactory wood
ring is 15 Pa. The ue needs to be inspected and
approved before installation.
