We accept no liability should any damage result from the failure to comply with theinstruc-
tions contained in this technical manual.
Essential recommendations for safety
• It is strictly prohibited to carry out any modifications to the appliance without the
manufacturer’s prior and written agreement.
•
The product must be installed by a qualified engineer, in accordance with
applicable local standards and regulations.
• The installation must comply with the instructions contained in this manual and
with the standards and regulations applicable to domestic hot water tanks.
• Failure to comply with the instructions in this manual could result in personal
injury or a risk of environmental pollution.
• The manufacturer declines all liability for any damage caused as a result of
incorrect installation or in the event of the use of appliances or accessories that are
not specified by the manufacturer.
Essential recommendations for the correct operation of the appliance
• In order to ensure that the appliance operates correctly, it is essential to have it
serviced by a certified installer or maintenance contractor every year.
• In case of anomaly, please call your installer for advice.
• Faulty parts may only be replaced by genuine parts.
• Our water heaters are designed and manufactured for the exclusive purpose of
heating and storing domestic hot water.
• The domestic hot water heaters must only be heated using hot water in a closed
circuit.
General remarks
• The availability of certain models as well as their accessories may vary according to
markets.
• The manufacturer reserves the right to change the technical characteristics and
features of its products without prior notice.
• The part number (P/N) and serial number (S/N) of the appliance are indicated on its
rating plate and must be provided to ACV in case of warranty claim. Failure to do
so will make the claim void.
•
In spite of the strict quality standards that ACV applies to its appliances during
production, inspection and transport, faults may occur. Please immediately notify
your approved installer of any faults.
NOTES
This manual contains important information with respect to the installation, the starting up and
the maintenance of the appliance.

TECHNICAL CHARACTERISTICS
G3 REQUIREMENTS AND GUIDANCE  UK ONLY
Discharge pipe from safety valves
The Building Regulation G3 requires that any discharge from an unvented system is conveyed to
where it is visible, but will not cause danger to persons in or about the building.
The tundish and discharge pipes should be tted in accordance with the requirements and guid-
ance notes of Building Regulation G3. The G3 Requirements and Guidance sections 3.50 - 3.63 are
detailed below.
For discharge pipe arrangements not covered by G3 Guidance advice should be sought from your
local Building Control Ocer.
Main characteristics :
• Any discharge pipe connected to the pressure relief devices (Expansion Valve and Tempera-
ture/Pressure Relief Valve) must be installed in a continuously downward direction and in a
frost free environment.
• Water may drip from the discharge pipe of the pressure relief device.
• This pipe must be left open to the atmosphere.
• The pressure relief device is to be operated regularly to remove lime deposits and to verify that
it is not blocked.
A typical discharge pipe arrangement is shown further on.
General remarks
• Discharge pipe-work D2 can now be a plastic pipe but only pipes that have been
tested to a minimum 110°C must be used.
• Discharge pipe D2 can now be plumbed into the soil stack but only soil stacks that
can handle temperatures of 99°C or greater should be used.
Extract from “The Building Regulation G3” :
Discharge pipe D1
3.50 Safety devices such as temperature relief valves or combined temperature and pressure and
pressure relief valves (see paragraphs 3.13 or 3.18) should discharge either directly or by way of a
manifold via a short length of metal pipe (D1) to a tundish.
3.51 The diameter of discharge pipe (D1) should be not less than the nominal outlet size of the tem-
perature relief valve.
3.52 Where a manifold is used it should be sized to accept and discharge the total discharge from the
discharge pipes connected to it.
3.53 Where valves other than the temperature and pressure relief valve from a single unvented hot
water system discharge by way of the same manifold that is used by the safety devices, the ma-
nifold should be factory fitted as part of the hot water storage system unit or package.
Tundish
3.54 The tundish should be vertical, located in the same space as the unvented hot water storage sys-
tem and be fitted as close as possible to, and lower than, the valve, with no more than 600mm of
pipe between the valve outlet and the tundish.
Note: To comply with the Water Supply (Water Fittings) Regulations, the tundish should incorporate a
suitable air gap.
3.55 Any discharge should be visible at the tundish. In addition, where discharges from safety de-
vices may not be apparent, e.g. in dwellings occupied by people with impaired vision or mobi-
lity, consideration should be given to the installation of a suitable safety device to warn when
discharge takes place, e.g. electronically operated.

TECHNICAL CHARACTERISTICS
Discharge pipe D2
3.56 The discharge pipe (D2) from the tundish should:
(a) have a vertical section of pipe at least 300mm long below the tundish before any elbows or
bends in the pipework; and
(b) be installed with a continuous fall thereafter of at least 1 in 200.
3.57 The discharge pipe (D2) should be made of:
(a) metal; or
(b) other material that has been demonstrated to be capable of safely withstanding tempera-
tures of the water discharged and is clearly and permanently marked to identify the product and
performance standard (e.g. as specified in the relevant part of BS 7291)
3.58 The discharge pipe (D2) should be at least one pipe size larger than the nominal outlet size of
the safety device unless its total equivalent hydraulic resistance exceeds that of a straight pipe
9m long, i.e. for discharge pipes between 9m and 18m the equivalent resistance length should
be at least two sizes larger than the nominal outlet size of the safety device; between 18 and
27m at least 3 sizes larger, and so on; bends must be taken into account in calculating the flow
resistance. See figure, table and the worked example.
3.59 Where a single common discharge pipe serves more than one system, it should be at least one
pipe size larger than the largest individual discharge pipe (D2) to be connected.
3.60 The discharge pipe should not be connected to a soil discharge stack unless it can be demonstra-
ted that that the soil discharge stack is capable of safely withstanding temperatures of the water
discharged, in which case, it should:
(a) contain a mechanical seal, not incorporating a water trap, which allows water into the
branch pipe without allowing foul air from the drain to be ventilated through the tundish;
(b) be a separate branch pipe with no sanitary appliances connected to it;
(c) if plastic pipes are used as branch pipes carrying discharge from a safety device they should
be either polybutalene (PB) to Class S of BS 7291-2:2006 or cross linked polyethylene (PE-X) to
Class S of BS 7291-3:2006; and (d) be continuously marked with a warning that no sanitary ap-
pliances should be connected to the pipe.
Note:
1. Plastic pipes should be joined and assembled with fittings appropriate to the circumstances in
which they are used as set out in BS EN ISO 1043-1.
2. Where pipes cannot be connected to the stack it may be possible to route a dedicated pipe along-
side or in close proximity to the discharge stack.
Termination of discharge pipe
3.61 The discharge pipe (D2) from the tundish should terminate in a safe place where there is no risk
to persons in the vicinity of the discharge.
3.62 Examples of acceptable discharge arrangements are:
(b) to a trapped gully with the end of the pipe below a fixed grating and above the water seal;
(c) downward discharges at low level; i.e. up to 100mm above external surfaces such as car
parks, hard standings, grassed areas etc. are acceptable providing that a wire cage or similar
guard is positioned to prevent contact, whilst maintaining visibility; and
(d) discharges at high level: e.g. into a metal hopper and metal downpipe with the end of the di-
scharge pipe clearly visible or onto a roof capable of withstanding high temperature discharges
of water and 3m from any plastic guttering system that would collect such discharges.
