User Instructions
Your system will run automatically in normal
use it will however require regular servicing,
it is essential that servicing is undertaken
by competent installer. It is advisable that
servicing of the vessel is timed to coincide
with the servicing of your heat source.
Water owing through the tundish indicates
that there is a fault, if the water is hot turn the
heat source o and allow water to cool (ow
may stop) call out a competent plumber.
Installation Instructions
What follows is essential for warranty validity.
It is the responsibility of the user and/or
installer to ensure that the unit is installed and
operated safely, and in accordance with the
instructions supplied below.
•The installation should also be in
accordance with the British Standard
Codes of Practice, current Building
Regulations, i.e. Health & Safety
Document No. 635 (The Electricity At
Work Regulations 1989), and the Water
Supply (Water ttings) Regulations,
BS 5449:1990 Forced circulation hot
water systems , BS 6700:2006 Design,
installation, testing and maintenance of
services supplying water. The relevant
regulations are: England and Wales
– Building Regulation G3; Scotland –
Technical Standard P3; North Ireland
– Building Regulation P5
•Installation must be in accordance with
the relevant requirements of the
Building regulations, IEE Regulations
and the Water Supply (Water Fittings)
Regulations. It should also be
in accordance with any relevant
requirements of the Local Authority
•Must be undertaken by a qualified
installer
•Must be supplied, with a Temperature/
Pressure safety valve (see Appendix A).
Where a heat exchanger is fitted an
unvented kit located on the cold water
supply must be fitted (see Appendix B).
•Lifting - on larger vessels lifting eyes
are available, do not use straps or
chains which may result in damage to
the vessel
•Do not lift a vessel using the insulation
where fitted straps may crush or
damage the insulation casing
•Siting, - ensure that the surface the
vessel is located on is firm and level to
prevent settling, pipe strain or distortion
of the vessel. Adequate space to enable
installation and servicing and access to
the inspection hatch and all connections
must be allowed for
•Pipework/connections - ensure threaded/
flanged connections from the pipework is
square on to the connections on the
vessel. Flanged connections, ensure that
the bolts are not tightened consecutively
around the flange but diametrically
opposite. Pipework connections must be
adequately supported to prevent any
stress to the vessel

•Before start up/testing and after
installation, check and if necessary
tighten the hydraulic connections
where a heat exchanger is tted
•tightening of the bolts should be in a
criss cross sequence, any leaks must
be rectied before start up
•Where a heat exchanger is tted and
the system is unvented. All unvented
systems must be tted with devices to
accommodate the expansion of water
during the heating cycle it is essential
that an unvented kit is located on the
cold water supply during installation
•Direct electrically heated (immersions)
must be tted together with a
dual thermostat incorporating an
independent high limit cut out
thermostat & a control thermostat
•All electrical work must be undertaken
by a qualied electrician
•Gradually ll the system ensure
adequate venting for air removal during
lling and that the drain valve is closed,
slowly open other system connections
where appropriate
•When the vessel is operating at working
temperature and pressure visually
check all connections and gaskets, if
necessary tighten bolts on the system.
•The working temperature of the buer
vessel should not exceed 99°C and the
working pressure should not exceed
8 bar
Maintenance
Maintenance will consists of testing and
checking if all components are working
properly, before attempting any internal
inspection/maintenance drain contents of
vessel, if tted with an electrical immersion
ensure the immersion is switched o
•Annual internal cleaning of the vessel
should be carried out to avoid corrosion
•Undo Bolts from inspection hatch (as
previously described) check for wear of
gasket, replace if necessary
•If tted with a heat exchanger, the heat
exchanger should be inspected in situ
annually, however, where the water is
particularly aggressive, it is advisable
that inspections should be carried out
every 6 month or so. Lime scale build
up on the heat exchanger will reduce
performance regular cleaning using
a suitable descaling agent will avoid
performance drop o
•Ensure all hydraulic connections are
secured and leak tested before and
during vessel rell
•Check that the Pressure/temperature
relief valve is operating any hot water
from the PT valve must be discharged in
a safe way reecting the requirements of
current legislation
•Ensure Immersion(s) are heating the
water to the correct temperature
•Electrical checks/tests on the immersion
and dual control thermostats must be
carried out by a qualied electrician
