SYSTEM DETAILS
In this diagram an additional pump is shown
fitted because the pressure loss in the central
Diverter Valve
(not mid position)
CH Bypass
heating system is too large for the district pump.

The pump is now fitted in the district supply
CH Bypass
because the pressure loss over the BoilerMate
CH flow to dwelling CP coil is too large.

Here, the plate heat exchanger has been fitted
because the expansion requirements of the
Open vented feed and expansion central heating system are to be handled in the
Or Temp. filling loop required
dwelling rather than the whole system, or the
Open vented feed and expansion
CH flow to dwelling
Or Temp. filling loop required
components in the central heating system are
not capable of withstanding the pressure of the
CH flow to dwelling
CH Bypass district heating system.

Diverter Valve
In this instance, the plate heat exchanger
(not mid position)
Diverter Valve provides a full pressure break between the
(not mid position)
district heating system and the dwelling system.
CH flow to dwelling
The dwelling system will need to cater for
CH Bypass
expansion and circulation requirements. This
CH flow to dwelling
may be used where excessive district heating

pressure occurs.

The appliance is designed to be installed in an airing/cylinder cupboard and the
relevant minimum dimensions are provided in the Technical Data section of this
manual.
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 of the appliance and above
the Top up cistern. See the Technical Data section of this manual for further details.
The minimum dimensions contained in the Technical Data section of this manual
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 the
Technical Data section of this manual.
The appliance is designed to operate as quietly as practicable. If the plate heat
exchanger pump is noisy when the hot water tap is opened, then check the level
of water in the F & E cistern and vent the pump if necessary. Water hammer may be
caused by loose pipework and/or tap washers and/or washing machine valves.
Cupboard temperatures will normally be slightly higher than in a conventional system
and the design of the cupboard and door will need to take this into account. No
ventilation is normally required to the cupboard.
The separate Top up cistern will need to be located on top of the appliance or at high
level in the cupboard housing the BoilerMate CP. The dimensions and clearances are
provided in the Technical Data section of this manual. The location will need to provide
a suitable route for the cold feed expansion pipe as well as the open safety vent pipe.
The location will also need to provide a suitable route and discharge position for the
warning/overflow pipe and the ballvalve supply from the mains cold water system
(if provided) if these have been ordered as an optional extra.
Note: The standard appliance is supplied with a cistern without a ballvalve/
overflow for filling manually.
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/50Hz.
The sizes/types of electrical supplies must be as detailed in System Details section
of this manual. A means for disconnection from the supply mains having a contact
separation in all poles that provides full disconnection under over voltage category
III conditions must be incorporated in the fixed wiring in accordance with the wiring
rules. This shall be located within 1m of the appliance and only serve the appliance.
The hot and cold water 'first fix' pipework should be terminated 50mm above the
finished floor level in accordance with the dimensions provided in the Technical Data
section of this manual.
