1.7 Condensate Drain
A plastic drain pipe may need to be fitted to allow discharge of
condensate to a drain.
Condensate should, if possible, be discharged into the internal
household draining system. If this is not practical, discharge can
be made externally into the household drainage system or a
purpose designed soak away, see section 4.11 for more details.
1.8 Boiler Location
This boiler is not suitable for outside installation.
The boiler must not be installed in a room used or intended to
be used as sleeping accommodation or a room containing a
bath or shower.
In GB this is the current I.E.E. WIRING REGULATIONS and
BUILDING REGULATIONS.
In IE reference should be made to the current edition of I.S.813
"Domestic Gas Installations" and the current ETCI rules.
The boiler casing can be fitted at two heights. Refer to
diagram 1.4.
The boiler is assembled at the factory with the control box and
heat shield fitted in the lower position.
The boiler must stand on a level floor, conforming with local
authority requirements and building regulations.
The base temperature is within the requirements of the current
issue of BS5258. The boiler may stand on a wooden floor but
a metal base plate is required to protect plastic tiles and similar
floor coverings.
Suitable installation clearance needs to be available at the
sides of the boiler to facilitate direct connection of pipework and
making good around the flue assembly. The actual clearance
required will vary with site conditions.
When the boiler is to be installed level with work surfaces and
the like, minimum clearances should be provided as shown in
diagram 1.5. Work tops which overhang the cupboard sides,
almost in contact with the casing top, require a larger minimum
air gap. Flush sided fixtures require the same overall minimum
space but can have a reduced air gap on one side.
Boilers to be installed under work tops or fixtures, should be
positioned to provide minimum clearances as shown in diagram
1.6. To facilitate minimum clearances it may be necessary to
modify kitchen units and fixtures.
Combustible material must be a minimum of 25mm (1in) away
from the flue components, see diagram 1.6.
A front access clearance for servicing of 700mm, should be
provided.
The boiler can be installed within a cupboard, refer to minimum
ventilation and clearances as shown in diagram 1.7
If the boiler is to be installed in a cupboard or compartment,
make sure that nothing will obstruct the openings/vents in the
compartment.
A compartment used to enclose the boiler must be designed
and constructed specifically for this purpose. An existing
cupboard or compartment modified for the purpose may be
used. Details of essential features of cupboard or compartment
design are given in the current issue of BS6798.
Where the installation of the boiler will be in an unusual location,
special procedures are necessary the current issue of BS6798
gives detailed guidance on this aspect.
