The Advance Electric Combination boiler is perfect for modern all electric
apartment dwellers who prefer the comfort of wet central heating systems
and mains pressure hot water for powerful showers and quick bath filling.
The unit is supplied for use with a vented (open) central heating system and
also provides mains hot water. It should be installed so the top of the unit is
500mm above the top of the highest radiator. It can easily be converted to a
sealed system operation, please see page 11. It utilises off peak electricity for
economy in use and is pre-wired and pre-plumbed for ease of installation.
Two programmers are fitted to the unit, a timer for off peak (usually
overnight) electricity tariffs and a programmer for switching the central
heating on and off during the day. The central heating programmer/room
thermostat is wireless and can be used without the need for additional
wiring. The end user must set both of these.
There is sufficient hot water from an overnight charge for a shower and
a bath. A second immersion heater is fitted which should be wired to a
switched spur for hot water boost. If there are days when your hot water
needs increase this can be manually switched.
The product meets the HWA thermal store specification and parts G and L
of the Building Regulations.
The lower part of the store is dedicated to central heating. A 6kw
immersion heater is fitted for this purpose, and can be used in systems up
to four or five radiators. During start up periods the energy stored in the
lower part of boiler is ready for immediate use. If the water in the
radiators falls overnight to 20°C, for example, the 6kw heater is adequate
for demand of up to 10kw when first switched on in the day.
Note: Electrical repairs must only be undertaken by the manufacturer,
service agent or similarly qualified person in order to avoid a
hazard.
INTRODUCTION

5
When heating is switched on water is pumped from the store to the
radiators and has the benefit of providing immediate heat. A temperature
gauge is fitted for convenience and diagnostics. The store works at an
optimum temperature of 75°C . et temperature between 70°C and 75°C
on the thermostat dial. Note: this may need some fine tuning to get the
store to 75°C.
In the higher part of the tank is a large efficient hot water coil which draws
heat from the store for hot outlets in the property. It is connected to
the mains so provides fast safe hot water to all outlets without the need
for pumps. On one overnight charge this store will deliver enough hot
water for one bath and one shower.
Your morning shower will not be compromised if the heating is on.
Two programmers are supplied. The time clock on the tank is for
programming the unit to coincide with your off peak tariff electricity.
Please set this to co-incide with these off peak periods. This keeps running
costs down.
The remote wireless programmer is used for timing the on/off
periods of central heating and is left to the user. Please set this to suit your
own comfort and lifestyle.
Instructions are provided for these programmers.

Never lift the unit by holding the pipe work, always lift and position holding
the body of the tank. It is a 2 man lift.
Position the unit on a flat level surface that is capable of bearing 250kg with
controls and immersion heaters fully accessible for any future maintenance.
Leave a space of 200mm above the unit in case of a future requirement for
servicing. The unit can sit directly on the floor.

OPERATION

INSTALLATION
The unit must be installed to meet current best practice by a person
competent to do so.
Incoming mains of 22mm with a pressure of 2 bar or above is recommended
for best performance. Lesser pressures/pipe diameters will compromise
performance; this must be taken into account as the decision rests with the
installer/householder. Test the household supply by turning on a mains fed tap
to ensure satisfactory flow rate can be achieved.
Incoming pressures of more than 3 bar must be controlled at 3 bar by a pressure
reducing valve (Not supplied).
Recommended flow rate from 18 to 20 litres per minute. Excessive flow rates
may result in lower hot water temperatures.
In hard water areas where concentrations exceed 200ppm a suitable scale
reducer must be installed. The choice is left to the installer to suit local
conditions. Chlorine levels must be below 200ppm.
The overflow must be connected and it must be in line with current practice.
A metal overflow should be fitted. Push fit or solvent weld are not
recommended. Discharge must be to a safe and open, visible point outside of
the property. We also recommend that the ball valve is isolated after filling.
Inhibitor must be added via the top of the store to manufacturers’
recommended dosage.
A 22mm pipe set incorporating service valve, shock arrestor and blending
valve is fitted to the unit. This is needed to control the temperature at
the hot water outlets and prevent water hammer. The shock arrestor
should be checked annually and maintained at 3 bar pressure. The
blending valve calibration should also be checked annually to ensure water is at
an appropriate temperature.
The cold mains and domestic hot water are connected directly to this pipe work.
This should be done every year. Fill in the form at the back of this publication -
you
may need it in case of warranty issues. Keep proof of servicing (receipts etc).
ervice the expansion vessel by inflating to 3 bar, check condition of ball and
float valve and ensure store is inhibited with a proprietary brand of inhibitor.

PIPE WORK
CENTRAL HEATING
Pipe outside diameter Maximum heat loss in W/m
In order to comply with Part L Building egulations it is necessary to insulate
any hot water (primary and secondary) pipework within one metre of the
cylinder. Guidance is given in the Table 5 (Page 20) of the 2013 Domestic
Heating Compliance guide. Insulation values for the most popular pipe sizes
are reproduced below.
The heating is connected to the lower 22mm tappings on the right hand
side of the tank. A pump is fitted with isolation valves. Fit the flow to
the heating to the pump connection.
Note that heating is vented and the water level in the header tank must
be 500mm above the highest radiator. Central heating is self
commissioning. Once it is connected the unit will fill automatically.
See page 11 on converting to a sealed system.
adiators should be bled to remove any excess air from the system.
Use a two pipe system. Install thermostatic radiator valves but leave one
heat emitter fully open continually.
The system must be inhibited. Use a proprietary brand and recommended
dosage and concentration for central heating systems – don’t forget the store
volume of 210 litres.
To prevent nuisance gravity circulation (in Summer for example when heating
is not required) a non return valve is fitted.
IMMERSION HEATERS
The highest position immersion heater is 3kW and should be wired to a
15amp switched spur. It can be used as a boost if extra demand is placed
on the hot water during the day.
The lower immersion heater is 6kW and is wired to come on (a)
when programmed to match off peak periods by programmer labelled
OFF PEAK and (b) to come on during heating periods when the wireless
room thermostat and programmer calls for heat. Instructions are supplied
with the programmers.
The 6kw immersion heater is controlled by the thermostat on the store.

PROGRAMMERS
Two programmers are supplied with the unit - a wireless one with
integrated room thermostat for central heating and one attached to the
ECB which must be programmed to come on during off peak periods.
Consult your energy supplier regarding these times if you are unsure.
This is important and will help reduce running costs of the ECB.
The instructions for programming are supplied with these instructions
– they are separate leaflets and must be kept together with this
installation guide for future.
WIRING
The ECB is pre wired. The installer must be a qualified electrician and
the installation must meet all appropriate current egulations and Codes
of Practice.
A 3amp supply is to be wired to the main junction box as indicated in
the box, live to No. 1, Neutral to No. 2 and Earth to No. 3.
The large contactor must have a 30 amp switched and protected supply
connected as below inside the box. This supply must be direct from
the board in the property.
The higher immersion heater can be wired to a
15 amp switched spur for the householder to
use as boost during periods of heavy hot water
demand.
Note: The means for disconnecting and isolation
must be incorporated in the fixed wiring in
accordance with the wiring rules.
