6.7 For compartment installation the requirements of BS6798 and BS5440: Part 2 must be
met.
•
The compartment must be of suffi cient size to permit access for inspection and
servicing or the removal of the boiler and any ancillary equipment.
•
Any space used for airing clothes or storage must be separated from the appliance by
a non-combustible partition. Where the partition is formed from perforated material, then
the major dimension of the apertures shall not exceed 13mm.
•
No combustible surface must be within 20mm of the boiler casing without protection.
•
There must be 20mm clearance between the compartment door and boiler case.
•
Where the boiler's fl ue pipe passes through the airing space, it must be protected by
a non-combustible sleeve or fi re stop having a minimum clearance of 20 mm between
the fl ue pipe and sleeve. In addition, if the fl ue pipe passes through the partition then
the clearance gap of the fl ue pipe or its guard with the partition must not exceed 13 mm.
6.8 When the boiler is intended for use with LPG it must not be installed in a room or internal
space below ground level.
7. Flue Terminal Location
7.1. The fl ue terminal must be sited with minimum clearances as specifi ed in Figure 3. Note
if pluming becomes problematic or causes a nuisance a plume management kit is available
from your stockist.
7.2. Current regulations and standards require a terminal guard to be fi tted where the
terminal is accessible to touch or at risk of being damaged. All wall mounted terminals sited
within 2m of the level which people have normal access, should be adequately protected with
a suitably sited guard.
7.3. Where the fl ue terminates within 1m of a plastic or painted gutter or within 500mm
of painted eaves then protection should be provided in the form of an aluminium
shield at least 1m in length, fi tted to the underside of the gutter or painted surface.
7.4. The fl ue should not be sited where the condensate "plume" may give rise to a nuisance
factor under certain weather conditions.
NOTE: If you have diffi culty siting the fl ue in an appropriate location your supplier will be happy
to supply a "anti-plume management kit", which discharges the fl ue products at a higher level.
8. Flue (General)
8.1. The boiler utilises a concentric fl ue arrangement, which consists of a 60mm-diameter
inner fl ue and 100mm-diameter outer air inlet duct, which comes in either horizontal or vertical
arrangements. However, for greater fl exibility fl ues are available as 80/80mm twin pipes and
in circumstances where the plume may cause a nuisance horizontal and vertical
anti plume kits available.
NOTE: Only use approved Heatline fl ue products with this boiler, which can be sourced from
the supplier of your boiler or Heatline stockist.
8.2. The standard 705+/-5mm fl ue (fi gure 5) is not supplied with the boiler and should be
purchased separately from your supplier. This fl ue may be routed to the rear, left or right
of the appliance by means of the 90° degree bend, which is supplied in the fl ue kit (fi gure 4).
The bend is connected to the boiler using the screws provided and sealed with the gasket.
