UNICA BHE
SECTION 4
INSTALLATION
4.1
DELIVERY
Due to the weight of the appliance it may be
necessary for two people to lift and attach the
appliance to its mounting. The appliance is con-
tained within a heavy-duty cardboard carton. Lay
the carton on the floor with the writing the correct
way up.
4.1.2
APPLICATION
The Unica BHE can be installed within the property
or external to the property. Although the appliance
is certified IPx5D, if it’s to be installed externally,
it may be necessary to provide reasonable
protection from heavy or persistent rain however
this will be purely dependant on the location of the
appliance and local conditions. Alternatively, the
appliance enclosure (see fig 1B) can be used (not
supplied).
4.2
CONTENTS
Contained within the carton is:
•
the boiler
•
the wall bracket & fixing jig
•
template
•
an accessories pack containing appliance serv-
ice connections and washers
•
the instruction pack containing the installation &
servicing instructions, user instructions, guar-
antee registration card and a 3-amp fuse.
4.3
UNPACKING
At the top of the carton pull both sides open – do
not use a knife – unfold the rest of the carton from
around the appliance, carefully remove all protec-
tive packaging from the appliance and lay the
accessories etc. to one side. Protective gloves
should be used to lift the appliance, the appliance
back-frame should be used for lifting points.
4.3.2
PREPARATION FOR MOUNTING THE
APPLIANCE (external application)
T
he appliance and/or the appliance enclosure
should be mounted on a smooth, vertical,
noncombustible surface, which must be capable
of supporting the full weight of the appliance and/
or enclosure. Care should be exercised when
determining the position of the appliance with
respect to hidden obstructions such as pipes,
cables, etc. When the position of the appliance
has been decided - using the template supplied -
carefully mark the position of the wall-mounting
bracket (see fig. 6) and flue-hole (if applicable).
4.3.3
IMPORTANT
The Unica BHE can be used on various applications
(4.1.2). The following instructions relate to
external applications, i.e. external to the
property or dwelling.
4.4
PREPARATION FOR MOUNTING THE APPLI-
ANCE
The appliance should be mounted on a smooth,
vertical, non-combustible surface, which must be
capable of supporting the full weight of the appli-
ance. Care should be exercised when determining
the position of the appliance with respect to hidden
obstructions such as pipes, cables, etc.
When the position of the appliance has been
decided – using the template supplied – carefully
mark the position of the wall-mounting bracket
(see fig. 8) and flue-hole (if applicable). If you
intend to run the pipe-work vertically behind the
boiler, move the screws on the fixing jig from the
default position (No. 3) to position No. 5. You will
also require a spacer kit, part No. 435 (see 4.6).
4.4.1
EXTERNAL APPLICATIONS USING THE
ENCLOSURE
The Unica BHE boiler can be used withthe enclosure
(fig 1B). The Enclosure has been designed to be
recessed into an external wall or surface to give a
flush finish. It can however, be mounted onto an
external wall if required.
Should this application be preferred, it’s
recommended that any openings on the top of the
enclosure are sealed with a suitable silicone sealant
in order to minimise the ingress or rainwater.
The use of the enclosure allows the installation
pipework to be installed prior to the appliance
being installed.
Due to the enclosure being installed external to the
property, the flueing arrangements for the appliance
can be simplified.
PREPARATION
Refer to the enclosure instructions (supplied) for
specific installation instructions and details on the
required size of opening.
The enclosure is supplied with ‘knock-out’ panels
that allow the appliance flue outlet to routed to the
left, right, or vertically.
In addition, the flue can be routed through the front
of the enclosure.
The route and termination of the flue outlet must be
considered prior to the installation of the enclosure.
Refer to the relevant sections within this installation
booklet and the enclosure instructions for guidance,
and Install the pipework and electrical supply prior
to the fixing of the enclosure. Additionally, if the
flue system is to be routed within the fabric of the
property, then it’s advisable to carry this out before
fitting the enclosure.
At this point it will be necessary to remove the
‘knock-out’ panels that are specific to the route of
the flue system and pipework.
FIXING
Secure the enclosure to the wall using the relevant
fixing points, taking care to ensure that it is level
and corresponds to the pre-installed pipework and/
or flue system.
Alternatively the enclosure can be secured to an
external wall by modifying the rear panel to accept
fixing screws or bolts.
MOUNTING THE APPLIANCE
Mount the appliance onto the enclosure as indicated
in the enclosure instructions.
4.4.2
EXTERNAL APPLICATIONS WITHOUT THE
ENCLOSURE
The Unica boiler can be installed without the
requirement of an enclosure providing that some
form of protection is used to minimise the risk of
water penetration into the appliance (see fig 9A).
PREPARATION
Using the template and details in figure 6 and 7 as
a guide, secure the appliance wall bracket to the
external wall and mount the appliance to the wall
bracket.
