HEATING SYSTEM & CONTROLS
Any existing system must be suitable for sealed system
operation at up to 3bar pressure and may require
flushing/cleansing.
Isolation valves and drain point are required.
A time clock/room thermostat should be installed.
(Necessary to activate automatic power modulation).
If the installation includes thermostatic radiator valves or
automatic temperature zone controller, it is essential not to
interrupt the flow rate trough the boiler in any case, it will
cause E3 error or the action of safety thermostat.
HOT WATER SYSTEM
Competency to install unvented hot water system is
required.
Any existing system and controls (e.g. shower) must be
suitable to operate at mains water pressure.
The incoming water main pressure and flow must be
sufficient for requirements.
If incoming mains pressure is excessive (above 5 bar) a
pressure reducing valve is required.
The boiler safety valves require piping to a safe discharge
point. In hard water areas it is advisable to take normal
precautions against lime scale formation.
4.1 GENERAL REQUIREMENTS
The installation should be carried out by a person certified as
competent for the installation of unvented hot water systems
in accordance with current building regulations.
Installation should also be in accordance with the relevant
Standards and Codes of Practice.
4.2 UNPACKING & CONTENTS
Dispose of the cardboard packaging at a cardboard recycling
site. Observe national regulations.
4.3 LOCATION
The location should be clean and dry with no presence of
gases, explosives or flammable objects.
It is not suitable for installation outside and should be
protected from moisture and frost.
The boiler must be sited so that the boiler and controls are
not accessible to any persons whilst using a bath or shower
and there should be no possibility of water dripping or
splashing onto the boiler or controls.
Electrical safety regulations for clearances must be followed if
installed in a bathroom or shower area.
Where possible the boiler should be sited to minimize the
pipe distance to hot water outlets.
The power supply cable should be carefully routed and
secured and provision made for a suitable isolation switch
and MCB/RCD.
4.4 DIMENSIONS & CONNECTIONS
