5.0 INSTALLATION AND WIRING
5.1 SITE REQUIREMENTS
(a) The appliance is designed to be installed in an airing/cylinder cupboard on the
100mm high plinth supplied with the appliance and the minimum relevant
dimensions are provided in section 3. The minimum dimensions shown in figure
3.2 and Table 3.1, allow for the passage/connection of pipes to the appliance
from any direction as long as the appliance is installed on the base provided. if
the installation base is not used, extra space may be needed to allow connection
to the appliance pipework.
(b) A suitable location will normally be needed for the separate feed and expansion
cistern. This will often be at a high level in the cupboard housing the BoilerMate.
The appliance CF & OV pipework assembly has been designed so that the cistern
can be fitted on top of the BoilerMate appliance if required. The dimensions and
clearances are provided in section 3. The location will need to provide a suitable
route for the cold feed and expansion pipe as well as the open safety vent pipe
and also a suitable route for the warning overflow pipe.
(c) Because of ease of installation it is recommended that the cupboard construction
is finished and painted before installation of the appliance. The cupboard door
can be fitted after the installation.
(d) if the unit needs to be stored prior to the installation, it should be stored upright
in a dry environment and on a level base floor. For handling instructions please
see page 4 of this manual.
(e) The floor of the cupboard must be level and even and capable of supporting the
weight of the appliance when full. Also installation and maintenance access is
needed to the front of the appliance and above the F & E cistern. See Technical
Specifications (section 3) for further details.
(f ) The appliance is designed to operate as quietly as practicable. However some noise
from pumps etc. is inevitable in any heating system. This will be most noticeable
in cupboards formed on the bulkhead or at the mid span of suspended floor. in
these cases the situation can be improved by placing the appliance on a suitable
sound deadening material.
(g) When using push fit connectors with the flexible hose kits it is important to check
that they are compatible. We currently recommend push fit connectors from the
following manufacturers. The installer must check and confirm the suitability of
any other types of push fit connectors.
• Hepworth –Hep
O BiTite
2
• John Guest – Speedfit
• Yorkshire – Tectite
(h) The cupboard will normally be at marginally higher temperature than in a
conventional system and the design of the door and the cupboard will need to take
this into account. However no ventilation is normally required to the cupboard.
(i) A 230V/50Hz electrical supply must be available which is correctly earthed,
polarized and in accordance with the latest edition of the iEE regulations for
electrical installations BS 7671. The connection must be made using a double-pole
linked isolator with contact separation of 3mm in both poles which is located
within 1m of the appliance and it must only serve the appliance.
The rating of the electricity supply to the mCHP_BoilerMate must be 6.5kW at
230V ac (See also 3, section 4).
(j) The location site chosen for installing the mCHP unit must meet the requirements
of its manufacturer.
5.2
PREPARING APPLIANCE
FOR INSTALLATION
(a) Details of the recommended positions for
the termination of first fix pipework are
provided in section 3, figure 3.2a and 3.2b.
The pipework can be located or its position
checked using the template provided with
each appliance. if these have been followed,
then the installation is very simple and much
quicker than any other system.
(b) The appliance is supplied shrink wrapped
on a timber installation base. Carrying
handles are also provided in the back
of the casing. The appliance should be
handled carefully to avoid damage and the
recommended method is shown on page
2. The manual handling operations will
need to comply with the requirements of
Manual handling Operations Regulations
issued by H.S.E.
Before installation the site requirements
should be checked and confirmed acceptable.
The plastic cover and protective wrapping
should be removed and the installation
base provided with the appliance placed in
position.
(c) The appliance can then be lifted into
position in the cupboard on top of the
base. The front panel can then be removed
by unscrewing the 2 screws and lifting the
door up and out, ready for connection of
pipework and electrical supplies.
(d) The feed and expansion cistern support
shall be installed ensuring that the base is
fully supported and the working head of the
appliance is not exceeded (10m maximum).
Also the recommended access should be
provided for maintenance as shown in
section 3.
