WARNING - THE SURFACE OF THIS HEATER CAN BE HOT. The surface temperatures of this heater are within the requirements
of EN60335-2-61, the European Standard covering the safety requirements for Electric Storage Heaters, and momentary contact
with any part of the heater should not cause injury. However, in order to be effective, heaters of any type do get hot, especially
around the air outlet grille.
Therefore, if aged or infi rm persons, or young children, are likely to be left unsupervised in the vicinity of a heater precautions
should be taken to ensure that prolonged contact with the heater cannot occur. We recommend that a guard is fi tted around
the heater, as is normal with some types of heating appliances in similar circumstances. A range of guards specially designed for
Dimplex storage heaters is available. If you require further information on these guards, please contact the Dimplex Help Desk on
0845 600 5111.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack
of experience and knowledge, unless they have been given supervision for instruction concerning use of the appliance by a person
responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.
CAUTION: DO NOT COVER SURFACES OF THE HEATER AND DO NOT OBSTRUCT AIR OUTLET GRILLES. Surfaces of the
heater should not be covered or obstructed as this can cause excessive temperatures that can be hazardous and may cause safety
cut-outs to operate. For example, do not put clothes, fabrics or any combustible materials on the heater or allow curtains to come
within 75mm (3”) of the top and ends of the heater and do not allow furniture to be pushed up against the heater.
PLEASE NOTE: YOUR STORAGE HEATER IS VERY HEAVY AND MUST BE SECURELY FIXED TO A SOUND WALL.
No attempt should be made to move the heater without fi rst seeking specialist advice. If you are not happy that the heater
has been securely fi xed, please inform your installer. If, during any reassembly of the heater, a part of the thermal insulation shows
damaged or deterioration which may impair safety, it should be replaced by an identical part.
UNDER NO CIRCUMSTANCES SHOULD THE WALL FIXINGS BE LOOSENED ON THIS HEATER BEFORE THE BRICKS HAVE
BEEN REMOVED FROM ITS CORE.
DO NOT SIT OR STAND ON THE HEATER.
DO NOT PLACE OBJECTS IN CONTACT WITH THE HEATER.

reference. Note also the information given on the appliance.
Ultra-Slim Storage and Convector Heaters
IMPORTANT SAFETY INFORMATION
(85911 Iss. 6)
Models CXL12N, CXL18N and CXL24N
Your Dimplex CXLN combined storage and convector heater enables you to take advantage of cheap off peak electricity to provide the
bulk of your heating requirements, with the added fl exibility of a built-in, thermostatically controlled convector heater. This allows you to
provide top-up heat, for example, in very cold weather when the storage heater may not have suffi cient stored heat in reserve later in the
day for providing full comfort conditions. These operating instructions assume that the correct size of storage heaters have been selected
to cater for the heating requirements of the room.
STORAGE HEATER OPERATION
Setting the Controls
The control knobs have been positioned so that they are clearly
visible to an adult, but out of sight of young children. In this way
it is hoped that they will not provide temptation to a child to alter
the settings.
Domestic Use
In cold weather set the right hand (INPUT) knob to maximum (fully
clockwise). In milder weather set the control to a lower position.
Normally the left hand (OUTPUT) knob may be left on minimum
(fully anticlockwise). This control may be moved to maximum in
the evening if additional heat is required at that time. Return to
minimum before retiring.
Commercial Use
For normal commercial applications a setting of maximum on the
output control will ensure maximum output during working hours.
The input control should be set as described above for Domestic
Use.
Should these settings not provide the comfort levels
required, the more detailed instructions overleaf should
be consulted.

CXLN Storage heater section - Principle of operation
The storage heater section of the CXLN heater consists of a core of
high density heat storage bricks surrounded by a carefully designed
insulating case. During the night time off-peak period elements within
the brick core heat up the bricks to a temperature level determined
by the setting you select using the input control knob.
In the morning, when the core is at its hottest, the amount of heat being
transmitted through the insulation and emitted as radiant heat is at its
greatest and the heater feels hot over most of its upper outer surfaces.
Diagram 2.
As the day progresses, heat is transmitted from the heater to the room
and the outer surface of the heater becomes less hot and the amount of
heat released in this way becomes less.
If the amount of emitted heat becomes insuffi cient the output of the
heater and thus the room temperature may be increased by means of
the Output Control. This control operates a damper fl ap within the heater
which, when the output control knob is at minimum, covers vertical airways
which pass directly through the centre of the core of the heater. Even
when the outer surfaces of the heater are noticeably less hot, the core of
bricks can still be at a relatively high temperature. Opening the damper
fl ap by moving the output control away from minimum allows the room
air to circulate through this hot core and release more heat to the room
by convection. Diagram 3.
Input Control
The setting of this control determines the amount of charge taken in by the heater, which in turn determines the temperature of the
heater’s storage core. The higher the charge taken the higher the core temperature.
In colder weather the heater should be set to take a high charge, the control being set at maximum ensures the heater accepts a full
charge.
In the Autumn and Spring a lower setting of the input control knob should be suffi cient, the actual setting required being infl uenced by
the prevailing weather conditions, the room size and insulation levels. The most suitable settings will be found by experience.
Output Control
Depending upon the amount of charge accepted by the heater, the OUTPUT control allows the release of additional heat by means of
a damper which can be opened to allow a greater air fl ow through the heater core, and therefore additional circulation of heat. By altering
the setting of the Output control knob the damper may be opened and closed manually, or it may be made to open automatically.
Manual Operation
With the OUTPUT control on minimum the damper remains closed, and heat is released from the heater only by normal radiation and
convection around the outer surfaces of the heater. This alone may provide suffi cient heat on many occasions and therefore no alteration
of the OUTPUT control is necessary. However, if a boost of heat is required in the evening period, then moving the OUTPUT control
to maximum in the evening will immediately open the damper to allow more rapid release of any available stored heat. When the next
charging period commences the damper will automatically close to prevent this release of extra heat during the charge period, but the
OUTPUT control must be returned to minimum manually to obtain a similar operation the following day.
Page 4
Automatic Operation
The damper may be pre-set to open automatically each day if required. Setting the OUTPUT control at settings other than minimum
results in an automatic boost of heat. A high setting on the output control knob causes the damper to open early afternoon/evening,
conversely a lower setting causes it to open later.
Because the automatic opening of the damper is primarily dependent on core temperature then the amount of charge the heater has
taken has a bearing on the time at which the damper opens. For a given setting of the OUTPUT control, the colder the weather (and
consequentially, the greater the charge taken automatically by the heater) the later the damper will open.
Conversely, for a lower charge input (in milder weather) the earlier the damper will open for a given room temperature boost setting.
The most suitable settings of the Output control for different conditions will be found by experience.
Remember - a high setting of the OUTPUT control early in the day may leave too little heat stored in the heater for the evening, especially
during the less cold weather conditions.
CONVECTOR HEATER OPERATION
Convector Heater - Principle of operation
In addition to the storage heater section the CXLN incorporates a
convector heater element in the front of the heater which may be used
independently of the storage heater, for example to “top up” on very cold
days, or for use in late spring and early autumn when only infrequent
cold spells do not justify continuous use of storage heater. Cool air is
drawn in at the base of the heater, heated by the convector element, and
subsequently emitted from the grille at the top front of the heater.
The convector heater section is intended for use when the output of the
storage heater is not suffi cient to maintain the desired comfort level. For
the most economical operation of the CXLN, the heating system should
normally be designed so that the storage heater section provides the bulk
of the heating requirements, and the convector heater section provides
only top up heat, for example, later in the day in cold weather.
Switching on
To put the convector switch F in the ON position, depress the right-hand side of the switch. The switch neon will glow when the switch
is in the ON position. If the room temperature is below the thermostat setting neon C will glow, showing the convector is providing heat.
Setting the Thermostat
The thermostat knob A should be set to the comfort level required. Turning the knob clockwise will increase the room temperature
selected, but the actual setting to provide the required conditions will be found by experience. If, when the convector heater is switched
ON and available for use, the room temperature is below that set on the control knob, neon C will be illuminated, showing the heater
elements are energised.

IMPORTANT - Due to the newness of the materials the heater will produce a slight smell for the fi rst few days of operation. ROOMS
MUST BE WELL VENTILATED AND YOUNG CHILDREN, CAGED BIRDS, OR PERSONS WITH RESPIRATORY COMPLAINTS MUST
NOT REMAIN IN CLOSE PROXIMITY TO THE HEATER DURING THE FIRST 48 HOURS OF THE COMMISSIONING PERIOD.
Cleaning
To maintain the external appearance of the radiator it need only be wiped over occasionally with a dry duster. During the summer
months, or at other times when the appliance is not in use and is completely cold, the opportunity should be taken to wipe over with a
damp cloth. Do not use abrasive cleaning powders or furniture polish.
Discoloration of wall fi nishes can sometimes occur immediately above a storage heater due to the properties of some paints and
decorating materials or the presence of environmental impurities in the air (such as soot or incense generated from the burning of candles,
etc.) A suitable shelf (available from Dimplex) may be fi tted to limit the extent of any wall discoloration.
To commission the heater set both the input and output controls to maximum and leave for 48 hours, after this period the controls should be adjusted for everyday use - see ‘SETTING THE CONTROLS’ on the front cover of these instructions.
24-hour Convector Operation
In certain circumstances it may be desirable for the convector to be available during the off-peak period. If this is so the installer can
select this option during installation. However, the user should be aware of the following:
1. If the convector heater is not required during the off-peak period the user must remember to switch it off.
2. If the convector heater is used at a high level for a signifi cant period during the off-peak period it will have the effect of reducing the
level of charge taken by the storage heater for a given input setting. A higher setting of the input control may be required to compensate
for this.
