OPERATING INSTRUCTIONS
Heat Retention
This storage heater takes in energy when electricity
tariffs are low, and retains it in the insulated core.
Automatic Input Control
An automatic input control system varies the charge
taken in response to weather conditions, taking into
account the amount of energy already stored in the
heater. It therefore provides an economic heating
system requiring no adjustment by the user.
Core Discharge
A thermostatically controlled fan draws air through
the hot core, releasing the stored heat as and when
required, providing a level of room temperature
control superior to that of conventional storage
heaters.
Boost Heating
A supplementary direct acting element provides
additional boost heating when required. Although
this may function outside reduced tariff periods, the
boost will
only
operate when the more economical
‘stored energy’ is exhausted.
Setting the Controls
The controls are located at the top right hand
corner of the heater, both under the hinged
fl
ap,
and on the side panel.
Safety Instructions
1. Ventilate rooms well during commissioning.
2. Do not move the heater in any way once
installed without the services of a competent
electrician.
3. Do not cover the heater with clothing etc.
at any time, or position furniture close to, or
against, the heater.
4. Ensure clearances of at least 150mm between
the heater and curtains.
ALSO REFER TO COVER PAGE
Due to the newness of materials, the heater will
produce a slight smell for the
fi
rst few days of
operation. In order to dispel these odours as
quickly as possible:
(i) During the day
set the input room temperature
control to MAXIMUM and the boost switch to OFF,
allowing the fan to run as often as possible.
(ii) During the night,
ensure that the boost switch
is set to OFF, and reduce the room temperature
control setting to MINIMUM to enable the core to
accept its full charge.
Ensure both supplies are switched on at the
wall.
Normal Use
(after the
fi
rst 48 hours)
i)
Keep both supplies switched on at the wall.
ii)
When only background heat is required (eg.
when the room is unoccupied) set the temperature
control to minimum.
iii)
When more heat is required in the room (eg. when
the room is occupied) turn the temperature control
to 5 or 6 to set the required room temperature.
iv)
At night time, set the temperature control back
to MINIMUM, to allow the heater to accept its full
charge.
Principles of Operation
Control Functions
Output Controls
ROOM TEMPERATURE CONTROL
The room temperature control will allow the fan to
run until the desired room temperature has been
achieved. Once this has been reached the fan
will automatically cycle ON and OFF to maintain
this temperature. If the room feels too warm the
room temperature control should be adjusted
anticlockwise; conversely if the room feels too
cool it should be adjusted clockwise.
To maintain the appearance of the heater, wipe
occasionally with a dry cloth when the heater is cool.
Do not
use abrasive powders or furniture polish.
Discolouration 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 discolouration.

BOOST OPTION
Boost selection is controlled by a two position
illuminated rocker switch.
The boost option is only available when the fan
is in operation.
When the Boost is switched ON, the direct acting
element will be automatically activated (in 2
stages) to supplement the heat output from a
depleting core.
The switch will be illuminated whenever the fan is
running, although safety devices within the heater
will prevent the
fi
rst stage of the direct acting
element (half boost) being activated until the core
is partially depleted.
When the core is almost fully depleted, the direct
acting element will automatically switch to full
power (full boost).
Dependent on the option the installer has chosen
(see installation instructions point 4) the fan and
boost will operate as follows:
Option 1
(two stage fan recommended for
domestic installations)
If boost option is not selected Normal Fan will
operate.
If boost option is selected, the fan will

Input Controls
This heater is fitted with a user adjustable
automatic input control which varies the charge
taken in response to weather conditions taking
into account the amount of energy already stored
in the heater.
Set at 6 the heater takes a maximum charge and at
1 the heater takes a minimum charge at any room
temperature. The casing of the heater, particularly in
late evening, may feel cool, this is quite normal. The
input control may require a few days experimentation
before your comfort level is established.
Initially set the control to 3, the following evening
if the room is too warm reduce to 2 or if it is too
cool increase to 4. On subsequent evenings
adjust by half divisions until your comfort level
is achieved.
Having established the setting the input will
automatically vary the amount of heat stored to
compensate for weather conditions.
AFTER SALES SERVICE
automatically operate at Normal speed when
half boost conditions apply.
If boost option is selected, the fan will
automatically operate at High speed when full
boost conditions apply.
Option 2
(
single stage fan - recommended for
commercial installations)
If boost option is not selected High fan will
operate.
If the boost option is selected, the fan will
automatically operate at High speed when half
boost conditions apply.
If the boost option is selected, the fan will
automatically operate at High speed when full
boost conditions apply.
IMPORTANT
It is recommended that the boost function
be switched OFF when the heater is not in
use, especially overnight when the heater is
charging.
During very warm weather, the fan alone may be
used to circulate cool air.
