Important safety instructions
The use of any electrical appliance requires following common sense safety
rules. Primarily there is danger of personal injury and secondly danger of damage to
the appliance and property. These are indicated in the instructions text by the
following two conventions:
WARNING: Danger of personal injury.
IMPORTANT: Damage to the appliance.
In addition we offer the following essential safety advice.
General information
Scale build up can damage any appliance which boiling water passes through.
Burco autofill water boilers have an easy descale system to make descaling your
boiler and preventing it from scale damage as easy as possible. Failure to descale
your Burco autofill water boiler will invalidate your guarantee.
Before general use it is recommended that the unit is boiled and emptied
through the tap twice discarding the water each time. For best taste and to protect
your water boiler from limescale Burco suggest you filter the water supply.

Fitting a plug
The mains lead of this urn will already be fitted with a BS1363 13A plug. In the
event of replacing a fuse, a 13 amp fuse approved by ASTA or BSI must be used. If
the plug is not suitable for your socket then the plug must be cut off and disposed
of safely. An appropriate plug should be fitted as follows:
IMPORTANT: The wires in the mains lead are coloured in accordance with the
following code:
Green-and-Yellow - Earth
Blue - Neutral
Brown - Live
The wire, which is coloured green and- yellow, must be connected to the terminal
in the plug which is marked with the letter E or the earth symbol or coloured green or
green-and yellow. The wire, which is coloured blue, must be connected to the
terminal which is marked with the letter N or coloured black or blue. The wire, which
is coloured brown, must be connected to the terminal which is marked with the letter
L or coloured red or brown. Make sure that the connections are tight and that there
are no loose strands of wire and no insulation trapped under the terminals. Tighten
the clamp in the plug making sure that it grips the outer covering of the cord. In a
13A (BS 1363) fused plug, fit a 13A fuse. Tighten the plug cover securely.
If you are in any doubt, consult a qualified electrician.
IMPORTANT: The supply cord on this appliance is of a special type. If replaced,
only a Burco supply cord must be used. The supply cord may become warm when
the appliance is in use.

Connecting to a water supply
Your water boiler has been supplied with a suitable hose 7 for connection to a
drinking water supply. The water supply must have a pressure not exceeding 1000
kilopascals (10 bar) and no lower than 25 kilopascals (0.25 bar). If your water pressure
exceeds this, a suitable pressure reduction value will need to be fitted.
Please ensure that you follow the bye-laws of the water council when installing
this product.
Burco cannot be held responsible for water boiler malfunction if the water supply
pressure does not confirm as above. If in any doubt consult your water supply
company.
The hose supplied with the water boiler is manufactured from materials which
have been approved for drinking water and is rated at 10 bar at ambient temperature.
It is therefore recommended that the water boiler is only connected to a cold water
supply. Your guarantee could be invalidated and water contamination may occur if a
hose not supplied by Burco is used. Please note that washing machine hoses are not
suitable for use on this water boiler.
Connection to mains water supply
Your autofill water boiler can be set up so that the mains water connection can
either enter your water boiler at the back or the bottom of the unit.
To set up connection from back of unit:
• Using a screw driver remove blanking plate from back of unit A.
• Attach supplied water connection fitting to water inlet (screw fitting) and when
secure attach the pipe B.
• Tightly attach other end of water connection hose to mains water supply.
• Ensure all pipes are suitably insulated to prevent water supply from freezing.
• If rear overflow is required see instructions below on how to set this up at this
point.
To set up connection from bottom of unit:
• Using a screw driver remove blanking plate from back of unit A.
• Attach supplied water connection hose to water inlet with the elbow joint
connection on the hose (screw fitting) C.
• Tightly attach other end of water connection hose to mains water supply.
• Replace blanking plate.
Overflow
Connecting rear overflow
An air gap of 200mm from the connection point must be provided. Failure to
provide this air gap will cause an air lock and stop the water discharging in event of
an overflow.
IMPORTANT: For rear overflow connection a 14mm internal diameter hose or a
15mm internal diameter hose with a pipe clip must be used. While every reasonable
precaution is taken to prevent an overflow, Burco cannot be held responsible for any
damage caused as a result of incorrect installation or blockage of the overflow.
• Attach a suitable 14mm internal diameter or 15mm internal diameter hose
with a pipe clip, to outlet connection. (Hose not supplied)
• Attach other end of outlet hose to mains drain.
If connection to the bottom of the water boiler is desired now replace the
blanking place at the back of the unit, using screw driver to tighten in place.

Connecting your drip tray to
the mains drain
You are able to connect your drip tray to a mains drain inside the
counter your autofill water boiler is sitting on. To do this you will require
suitable hose and fittings.
You will need to follow the below procedure:
• Check that you have a connection to a suitable mains drain underneath your
work top.
• Position your autofill water boiler on your countertop. Remember to leave a
space at the back of the unit if you are connecting the unit to the mains water
supply/ connecting your overflow to protrude from the back of the unit.
IMPORTANT: Check that the hose you have is the correct length to reach
between mains drain connection and the bottom of the drip tray.
• When you are happy with the boiler position, remove the drip tray from your
autofill water boiler, take off the stainless steel drip tray cover.
• If you turn over the remaining section of the drip tray you will see in the centre
a raised circle, drill a hole through the centre of this circle. (It is suggested that
the drip tray is placed on a surface which you do not mind damaging before
you drill the hole, in case the drill goes through the hole and damages the
surface underneath.)
IMPORTANT: The hole you drill will need to be large enough to accommodate
the fitting you have purchased.
• Replace the drip tray on your autofill water boiler (still in desired position).
• Do not replace the stainless steel cover so that you are able to mark the
position of the hole on the work surface with a suitable marker.
• Remove drip tray and drill hole through work surface in marked location. Before
doing this ensure that there is nothing underneath your work top, which you
may damage when drilling through the work top.
IMPORTANT: The hole you drill will need to be large enough to accommodate
the hose/ fittings you have purchased.
• Attach hose at mains drain and pull through hole in work surface.
• Leaving enough spare length in the pipe to allow drip tray to be connected,
attach connecting fitting to the end of the hose protruding through the work
surface. Push connecting valve into the bottom of the drip tray.
• Replace drip tray and stainless steel cover.
Using
IMPORTANT: Always ensure unit is connected correctly to a water supply and
the supply is on before switching the appliance on.

After use
Switch off and isolate from supply. Water may be left in the water boiler when it
is not in use for short periods, for longer periods it should be emptied and cleaned out.
Protective cut-out
WARNING: The only parts you should touch behind the front panel
are the two red isolation valves. Touching any other part will put you in
danger of receiving an electric shock.
The heating element is fitted with a manual resettable thermal cut out which
protects the water boiler from damage if it were to overheat D. If your appliance
flashes 3 times, fails to heat up, appears ‘dead’ when switched on try the following:
Check the water boiler is plugged in to the mains and switched on both at the
plug/ spur and on the front of the unit. If this does not resolve the problem switch
off and disconnect unit, allow to cool, remove front panel (see process below). Reach
in carefully and on the underside of the element, between the two terminals you will
see/feel a reset button.
Press this upwards and the thermostat will reset. We would always recommend
descaling the water boiler after re-setting the thermostat as this is the most
common reason for the safety thermostat to have triggered.
If the safety thermostat activates repeatedly, even after descaling, contact the
Burco customer helpline.
After resetting the cut-out replace the front panel and top black plastic lid.
Reconnect to mains and switch on at plug/spur and on the front of the unit. If the
water boiler still appears dead contact Burco helpline.
Cleaning
WARNING: Disconnect from the electrical supply before cleaning
and allow the water boiler to cool.
IMPORTANT Do not immerse the water boiler in water or any other liquids and
take care to keep water away from the mains lead and connections.
There are two ways in which you will need to clean your autofill water boiler:
Externally; to do this follow external cleaning guidelines
Internally; to do this follow the Easy Descale Procedure below
IMPORTANT Do not use any abrasive cleaning fluids or materials.
External cleaning guidelines
WARNING: Always disconnect the plug from the mains and allow to
cool before cleaning.
To clean wipe the outside of your autofill water boiler with a damp cloth. It is
recommended that this is done daily. Stubborn stains may be removed using a good
stainless steel cleaner or non-abrasive cleaner.
Hard to reach areas should be cleaned using a small bristle brush and mild
cleaner.
IMPORTANT: Do not use abrasive cleaners on your water boiler as this could
scratch the finish of your water boiler.
To remove front panel of unit
• Remove black plastic lid 1.
