Regulations applicable to the country of use. In addition, the installation must be carried
out in-accordance with the relevant and current local and national specifications and
building regulations.
3.2
The fireplace surround, hearth and builders opening shall be of non-combustible material.
Hearth and clearance dimensions must comply with the requirements of BS 5071 part 3.
WARNING
:This appliance must not be fitted in any room where steam is present (e.g.
bathroom).
3.3
The minimum clearance height above fireplace opening for a combustible shelf (having a
depth of 150mm (6”) is 200mm (8”), add 12mm (½”) for each additional 25mm (1”) depth
of shelf.
WARNING
:Please note that soft wall coverings may become discoloured when close to a
heating appliance – this should be born in mind.
3.4
The minimum flue opening is 178mm (7”) diameter 250dq. Cm. (38½ sq. inches) and a
minimum effective height 3m (10ft). Provided that the flue, which is to serve this
appliance, satisfies the requirements of BS 5871:Part 3 then a terminal in-line fan
satisfying BS 5440: Part 1 may be used to improve flue draught.
WARNING
: The flue must
NOT
be shared with any other appliance.
3.5
All chimney dampers or restrictions should be removed or permanently fixed in the open
position.
WARNING
:If the fireplace has previously been used with a solid fuel the flue should be
swept clean prior to installation.
3.6
The room in which the appliance is to be fitted must have permanent air vent with a
minimum effective area of 100cm. Sq. (15½ sq. inches) and be accessible to the outside
air, unless specifically stated otherwise by the manufacturer.
NOTE:
Vent should be checked on a regular basis to ensure that there is no obstruction.
PRE-INSTALLATION CHECK
SECTION 4
FLUE SOUNDNESS
4.1
Using a smoke bomb, carry out a flue flow test to check the effectiveness of the flue and
ensure that there is no leakage into another part of the premises (including any loft) or, as
appropriate, other adjoining premises.
NOTE:Although a smoke pellet produces a large amount of smoke, the volume is small
compared with the volume of the combustion products from an appliance. Clearance of
smoke from a pellet is, therefore, no guarantee that the products of combustion from the
appliance will clear. This must be tested after the installation is completed by carrying
out a spillage test
WARNING:Smoke coming out of other than the correct terminal, or a down-draught or
no-flow condition, indicates as unsatisfactory flue. The flue may need attention – seek
expert advice.
VENTILATION
4.2
In line with 3.7 above, make sure that the room or space where the appliance is located
is adequately ventilated and that the means of ventilation is suitable.
