INSTALLATION
SITE REQUIREMENT
S
The appliance is designed to be installed in an airing/cylinder cupboard and the
relevant minimum dimensions are provided in Table 1.2 Technical Data.
Because of the ease of installation we recommend that the cupboard construction is
completed and painted before installation of the appliance. The cupboard door can
be fitted after installation.
If the unit needs to be stored prior to installation it should be stored upright in a dry
environment and on a level base/floor.
Installation and maintenance access is needed to the front and top of the appliance.
See Table 1.2 Technical Data for further details.
The minimum dimensions contained in Table 1.2 Technical Data allow for the passage/
connection of pipes to the appliance from any direction as long as the appliance is
installed on the installation base provided. If the installation base is not used extra
space may be needed to allow connection to the pipework and the whole of the base
area should be continuously supported on a material which will not easily deteriorate
if exposed to moisture.
The floor of the cupboard needs to be level and even and capable of supporting the
weight of the appliance when full. Details of the weight when full is provided in Table
1.2 Technical Data.
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 bulkheads, or at the mid span of a suspended floor. In these
cases the situation can be improved by placing the appliance on a suitable sound
deadening material (i.e. carpet underlay or similar).
The appliance is very well insulated and no ventilation is normally required to the
cupboard.
A suitable location will be needed for the unvented store expansion vessels. This will
often be on top of the appliance itself or at high level in the cupboard housing the
BoilerMate A-Class HP-DEM appliance. The dimensions and clearances are shown in
section 1.2 Technical Data. A location is also required for the primary system expansion
vessel as well as a suitable route for the connecting pipe from the BoilerMate A-Class
HP-DEM appliance to the expansion vessel. A suitable route and discharge location will
also be required for the discharge pipe from the P & T valve and ERV for all models.
An electrical supply must be available which is correctly earthed, polarized and in
accordance with the latest edition of the IEE requirements for electrical Installations
BS 7671.
The electrical mains supply needs to be 230V AC/50Hz/Single Phase.
Connection must be made using a double-pole linked isolator with a contact
separation of 3mm in both poles which is located within 1m of the appliance. The
supply must only serve the appliance.
The supply to all models shall be rated at 32 amp.
