1. Introduction
The Advance unvented water heater is a high quality stainless steel unvented cylinder to
provide hot water from a cold mains water supply of between 3 bar and 16 bar.
Reduced performance is available at lower pressures although the units are not suitable
for pressures lower than 1.5 bar and a flow rate of less than 20 litres per minute. The
indirect heat exchange surfaces are designed to provide a rapid heat up time. The
unit comes complete with all the necessary safety equipment to comply with legislation
governing the installation of such systems. The Advance solar unvented water heater
has been designed for use with all solar panels and for heat pump systems a special
range is available.

Two Port Valve
The motorised valve supplied and the thermal
cut-out (Hi limit stat) must be fitted to the primary
flow (Use compression fittings only).
The two port valve should be wired to the thermostat
(see Fig 8 or 9) depending on required configuration.
Connect the live supply to the thermal cut-out and
connect the brown wire of the two port valve to
terminal 2 on the thermosta. Earth and Neutral
supplies can be connected directly to the valve.
Operation of the cut-out and motorised valve;
to comply with regulations and to prevent the
temperature reaching 100°C the thermal cut-out
supplied must be fitted.
The thermal cut-out is wired in series to the cylinder
thermostat. When the thermal cut-out senses an
abnormalrise in temperature in the primary flow the
electrical supply to the motorised valve will be cut,
and the valve will bein the closed position thus
cutting off the primary water from the boiler to the
indirect coil in the cylinder. If this occurs it must be
reset manually.
The orange wire of the two port valve should be
connected to the central heating boiler and the
cylinder thermostat set to 60°C.
The power supply to the pump station should be
connected via the lower valve.
If the thermal cut-out operates check the cylinder
stat and or boiler stat.
2.4 Tundish
Tundish
External Expansion Vessel
The tundish supplied must be fitted so it is visible to
the occupie. The discharge pipe must be 22mm
copper pipe. Regulations do not permit more than
3 x 90 - degree bends between the Advance unit
and the outflow. Between the temperature &
pressure relief valve and the first 90-degree bend
there must be a fall of at least 300mm. The fall of
the pipework must be continuous and the pipe
should terminate in the gully or be bent backwards
onto an outside wall, in a place where discharge
cannot be injurious to persons.
This smaller tank is connected to the cold-water
inlet side of the vessel. Mount the tank according
to separate manufacturers instructions provided
with the External Expansion vessel (see Fig 7).
If you need to site the Advance unit in the middle
of the house your discharge pipe to the tundish
can be as far away as 9m, which in most cases is
enough to run the final discharge point. After 9m,
increase the pipe size to a greater diameter than
22mm and accordingly for subsequent 9m lengths,
(Table 1).
A suitable expansion vessel with a pre-charge
pressure of 3.5 bar is supplied with the Advance
solar.
The expansion vessel should be Tee’d off between
the pressure relief valve and the cylinder
(see installation diagram) and should always be
positioned with the entry point at the bottom
Installation should always be by means of a
standard T connector ensuring no other valve
is between this and the cylinder. Adjust the
pressure to 3.5 bar.
2.4 Tundish (Continued)
Scale
In hard water areas lower water temperatures can result in less scale being deposited.
If a water softener is used it should be capable of flows of approximately. 50 lt/min, this will maintain
maximum performance of the Advance unit. If no descaler or softener is used then the heating
element(s) will need descaling periodically for maximum efficiency and to prevent damage.
(Fig. 11) Tundish Installation
IMPORTANT: Regular
checks should be
carried out to ensure
that the expansion
vessel is correctly
pressurised to 3.5
bar at all times.
2.5 Discharge Pipework
G3 Requirement
‘...there shall be precautions
...to ensure
that the hot water discharged from
safety devices is safely conveyed to
where it is visible but will not cause
danger to persons in or about the
building.’
G3 Guidance Section 3.5
The discharge pipe (D1) from the vessel
up to and including tundish is generally
supplied by the manufacturer of the hot
water storage system
. Where otherwise
the installation should include the
discharge pipe(s) (D1) from the safety
device(s). In either case the tundish

2.5 Discharge Pipework (Continued)
Termination of Discharge Pipe Sizing
Worked Example of Discharge Pipe Sizing
The discharge pipe (D2) from the undish should
terminate in a safe place where there is no risk to
persons in the vicinity of the discharge.
The example below is for a G 1/2
temperature relief valve with a discharge
pipe (D2) having 4 No elbows and
length of 7m from the tundish to the
point of discharge. From table 1:
(overleaf)
Examples of acceptable discharge arrangements are:
a. to a trapped gully with the end of the
pipe below a fixed grating and above
the water seal;
b. 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,
c. discharges at high level: e .g . into a
metal hopper and metal downpipe
with the end of the discharge 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 .
The discharge would consist of high temperature water and
steam roofing felt and non-metallic rainwater goods may be
damaged by such. Asphalt, discharges.
Maximum resistance allowed for
a straight length of 22mm copper
discharge pipe (D2) from G1/2
temperature relief valve is 9m
. Subtract
the resistance for 4 No 22mm elbows
at 0. 8m each = 3 .2m, therefore the
permitted length equates to 5.8m. This
is less than the actual length of 7m
therefore calculate the next largest size
.
Maximum resistance allowed for a
straight length of 28mm pipe (D2) from
a G1 /2 temperature relief valve equates
to 18m Subtract the resistance of 4 No
28mm elbows at 1m each = 4m .
Therefore the maximum permitted
length equates to 14m As the actual
length is 7m a 28mm (D2) copper pipe
will be satisfactory.
.
(Fig. 12) Typical discharge pipe arrangement
IMPORTANT: The discharge will
consist of scalding water and
steam. Asphalt, roofing felt
and non-metallic rainwater
goods may be damaged by
such discharges.

and/or shut down the boiler.
Close the stopcock valve to
isolate the Advance unit.
Safety Checks
Any water coming from either
the expansion relief valve or the
temperature / pressure relief valve
during heat up is indicative of a
problem which needs to be identified
and rectified. The temperature relief
and expansion relief valves should be
fully opened, one at a time then both
together allowing as much water as
possible to flow through the tundish.
Check that your discharge pipework
is free from debris and is carrying the
water away without spillage over the
tundish and release the valves and
check that they reseat properly
