IMPORTANT
These instructions should be read carefully and retained for future reference.
Note also the information given on the appliance.
This heater is VERY HEAVY. In order to maintain stability
and to ensure its future safety in use, it is essential that the
heater is FIXED SOUNDLY TO A WALL and that the feet
are mounted on a FIRM, LEVEL SURFACE. Care should
be taken to avoid irregular surfaces, such as may result
from tiled surrounds partially protruding under the heater.
It is important that the following instructions are strictly
followed.
IT IS IMPORTANT THAT THE FIXING DEVICE CHOSEN IS
APPROPRIATE TO THE WALL MATERIAL TO WHICH THE
HEATER IS BEING FIXED. SOME MODERN INTERNAL
BUILDING MATERIALS ARE VERY LOW DENSITY BLOCK
AND REQUIRE SPECIALISED FIXING DEVICES TO PROVIDE
A SAFE, SECURE INSTALLATION.
THE HEATER MUST BE INSTALLED WHERE IT IS IMPOSSIBLE
FOR SWITCHES AND OTHER CONTROLS TO BE TOUCHED BY
A PERSON USING A BATH OR SHOWER.
The installation of this appliance should be carried out by
competent personnel and be in accordance with the current IEE
wiring regulations. For the assembly of the heater tools required
are a No. 2 pozidriver, an electrical screwdriver with a 4mm
wide blade and a 8mm AF open ended or box spanner. A small
mirror will aid insertion of the front panel retaining screws.
Only Heat Resisting Cable (min. rating T85) should be used.
DO NOT COVER OR OBSTRUCT the surfaces of the
appliance.
DO NOT INSTALL the heater immediately below a socket
outlet.
DO NOT POSITION under windows where curtains may contact
the heater. (See minimum clearances, stage 5).
DO NOT PLACE OBJECTS in contact with the heater.
If, during any reassembly of the heater, a part of the thermal
insulation shows damage or deterioration which may impair
safety, it should be replaced with an identical part.
Connection to a 30 amp Ring Circuit
The storage heater section of the CXLN/CXLSN
should not be connected to a 30 amp ring circuit.
A means for disconnection must be incorporated in
the xed wiring in accordance with the wiring rules.
The convector section may be connected to a 30 amp
ring circuit by either of the following methods.

    Why is my Dimplex CXL12N too cold?
    • J
      Joshua MunozAug 10, 2025
      Several factors can cause your Dimplex heater to feel too cold. There may have been a power interruption during the off-peak period, affecting the heater's charge. Ensure the off-peak circuit is working, the wall switch is on, and the fuse is okay. You can also try turning up the INPUT control, but note that it may take up to 24 hours to take effect. Alternatively, turn on the 'boost' function. If the heater was covered, the safety cut-out might have been activated, in which case you should contact Customer Services. Also, if you have an automatic heater, the room temperature can affect the charge taken.

    What to do if my Dimplex Heater is colder than another one?
    • P
      Patricia PerezAug 15, 2025
      If you have two automatic Dimplex heaters in one area, they might be affecting each other. To resolve this, set one heater higher as a 'primary' heat source and the other lower to provide 'supporting' heat. This prevents them from cancelling each other out and taking a reduced charge.

    Why is the front panel of my Dimplex CXL heater cool?
    • A
      Anthony LewisAug 20, 2025
      If you have a Dimplex CXL heater, a cool front panel is normal because it's spaced further from the storage bricks than on other storage heaters. If you want more heat, turn the INPUT control up. Alternatively, turn the OUTPUT control down or set the OUTPUT control to minimum, turning it to maximum in the evening for more heat.

      Return the OUTPUT control to minimum before you go to bed so that the Dimplex heater can take a full charge.

    How to fix black marks on the wall from my Dimplex storage heater?
    • J
      Jerome RiveraAug 30, 2025
      Black marks on the wall above or to the sides of your Dimplex storage heater are often caused by lit cigarettes, candles, or oil burners combined with the heater's convection effect. To address this, consider installing a shelf above the heater. This will divert the rising heat away from the wall and into the center of the room.

    Why does my Dimplex CXL12N Heater have smells other than during commissioning?
    • R
      Rachel FigueroaSep 4, 2025
      Apart from the initial commissioning period and dust accumulation after long periods of inactivity, your Dimplex heater should not produce smells. If decorating is being carried out, especially with petrochemical-based substances, turn off the storage heater and ensure the room is well-ventilated before turning it back on.
