Technical manual "1295"
2.1 Warning to the user
All the local and national regulations, and
in particular those relating to national and
European standards, must be observed when
installing the appliance.
An incorrectly installed heating appliance can
cause serious accidents
(chimney fires, burning of
plastic insulation materials in partition walls, etc.).
This stove is exempted by DEFRA for burning wood
logs in UK Smoke Control Areas (SCA). DEFRA
exemption is dependent upon the appliance being
fitted with a mechanical stop to prevent closure of the
secondary air control beyond the 25% open position.
You should check that this stop mechanism is fitted
before installation of the stove and certainly before
using the stove in a SCA to burn wood logs. If the stop
mechanism is fitted then the minimum chimney flue
diameter can be 125 mm but if the stop mechanism
is not fitted then the stove is not exempted and
the minimum chimney flue diameter is 150 mm in
accordance with Approved Document J of the building
regulations.
The insulation of both the appliance and the exhaust
gas pipe has to be reinforced and done according to
the Standards and the Bui lding Regulations for safety
reasons. The installation must be carried out according
to the standards and the Building Regulations.
It is the installer responsability to ensure that the
manufacturer's intructions are complied with.
2.2. The room
Ventilation
: To ensure that the appliance operates
correctly it is vital that sufficient air is provided for
combustion purposes. Check that sufficient air is
available in the room for combustion. Il a VMC
(controlled mechanical ventilation) is present, the
room pressure will be low and a non-closing external
air intake must be installed in addition to the chimney
itself of a minimum 50 cm2.
Position of the unit
: For new installations, select a
central position within the house, to provide a good
heat distribution around the building.
The heat distribution towards the other rooms will be
made through the communicating doors.
These rooms must be in negative pressure or must
include ventilation gratings.
Floor and walls
:
Make sure that the floor can support the weight of the
appliance, it's flue and any surround. The floor May
need to be re-inforced with e concrete screed to
distribute the weight load. The floor must not be
made of or covered with combustible materials, as
per the Building Regulations. Il combustible material is
present it will be necessary to install a non-combustible
covering.
