INSTALLATION
3. CONNECTION OF THE MAINS CABLE
- Connect the restricted (E7) supply to the
terminal block, marked “Storage Circuit”,
having first passed the cable through a front
cable clamp in the base. Connect the
unrestricted (Peak) supply to the terminal
block, marked “Fan/Boost Circuit”, having
passed this cable through another cable
clamp in the base.
At this point, if desired, an external fan/boost
timer may be fitted to the heater by passing
the two wires from the timer through the
remaining cable clamp, and connecting
them across the terminal block, marked
“Timer”, having already removed the link
fitted across this block at the factory.
Connect the EARTH lead from both
supplies to the terminal marked with the
symbol
IMPORTANT DURING NORMAL OPERATION ENSURE
SUPPLIES ARE SWITCHED ON AT THE WALL.
BOTH
Two supplies are required for the
operation of this heater - a restricted Off
Peak or Economy 7 supply for the storage
circuit, and an unrestricted supply for the
fan boost element circuit.
Thermostatic fan / boost control is
provided on the heater, however the fan /
boost operation may be customised by
the introduction of an external timer to
the heater (see section 3).
1. ENSURE THAT FIXING KIT HAS BEEN
LOCATED BEFORE DISPOSING OF
PACKAGING.
Remove the front panel by removing the
three screws along its bottom edge. With
hands positioned on each side of the panel,
lift upwards to unhook the top edge whilst
pressing down on the top panel with your
thumbs. The panel can now be lifted clear
and set to one side.
Remove the packing pieces from the slots
on the inner front (3 on the FXL18N and 4
on the FXL24N).
4. FAN SPEED SELECTION - At this point
the installer must choose between Normal/
High Fan or permanent High Fan option.
Option 1 - The heater is factory set at Normal
Fan. The fan will therefore:-
(a) Run at NORMAL when the boost option
is not selected.
(b) Run at NORMAL when the boost is
selected and the core is partially
depleted.
(c) Automatically switch to HIGH when the
boost is selected and the core is almost
fully depleted.
Option 2 - If a High Fan is permanently
required the installer must make the
following adjustment.
(a) Loosen the two screws securing the
wires to the resistor block.
(b) Move the right wire to the left of the block
and tighten both wires in the left
connection point of the resistor block
effectively taking the resistor out of
circuit.
See Fan/Boost Circuit Diagram
5. Ensure that any slack is pulled back
through each clamp and tighten the
clamping screws. Secure cables to base of
heater using ties provided in fixing kit.
6. Place the heater on its feet, and in the
desired position against the wall - DO NOT
LIFT THE HEATER BY ITS TOP PANEL!
Ensure that the heater is based on a firm
level surface, at least 100mm from any end
wall, and at least 100mm below any shelf
or similar projection. Cut away the gripper
rod or carpet which would prevent the
heater sitting firmly on the floor.
7. Mark the position of the two outside
corners of the wall bracket with the heater
pushed tight against the wall. Remove the
wall bracket from the heater by removing
the screw at each end. Place the heater to
one side and reposition the bracket against
the wall using the corner marks for
alignment.
Four fixing positions must be chosen for
the FXL24N and three for the FXL18N. Mark
the positions for the fixing holes - two at the
extreme ends and others spaced evenly
between them. Remove the bracket from
the wall, drill the holes in the positions
marked, and insert suitable fixings
previously described. Secure the wall
bracket to the wall using the correct
fasteners.
8. THE FOLLOWING MUST BE APPLIED
WHEN FIXING THE HEATER TO THE WALL
BRACKET.
i) If no skirting board is present secure
the heater through the wall bracket slots
closest to the wall.
ii) If 100mm (4 in.) skirting is present
secure the heater through the outer
slots.
iii) If skirting taller that 150mm (6in.) is
present this must be reduced to 150mm
(6 in.) over the entire width of the heater
plus 25mm (1 in.) at each end.
Do not fully tighten these screws until the
bricks are loaded into the heater as some
settling of the heater may occur.
NOTE: NEVER REMOVE THESE SCREWS
WITHOUT FIRST UNLOADING THE
HEATER.
9. Remove one element to allow access
for the back rows of bricks. On the FXL24N
remove the element to the right of centre
and on the FXL18N remove the central
element.
Loosen the two screws securing the
element tails in the ceramic connector
block, and lift the element up and out of the
heater.
10. Carefully fit the bottom row of the
back layer of bricks placing the two end
bricks into position first. Ensure that the
recess in the bricks is toward the rear of
the heater with the narrow end to the
bottom. Repeat this with the top row of
the back layer of bricks but the narrow
end of the recess must be to the top.
Refit the element which had been removed
by feeding the tails down through the hole
in the base insulation and into the connector
block. Ensure the element is fully pushed
home, then securely tighten the two screws
in the block.
11. Fit the front layer of bricks with the
recess toward the front of the heater.
The complete core will comprise:
FXL18N : 3 x 4 brick columns
FXL24N : 4 x 4 brick columns
12. Replace the inner front, complete
with insulation, by locating its bottom edge
behind the front lip of the chassis and
inserting the retaining screws along the top
and sides.
Refit the three inner guards in their
respective locations.
Replace the outer front by hooking the
upper grille into its retaining slot on the top
panel, lower into position and replace the
three self tapping screws along the bottom
edge.
13. Finally, tighten the screws at each
end of the wall bracket. Ensure that all
screws have been tightened as this is
essential to maintain earth continuity.
OPERATING INSTRUCTIONS
Principles of Operation
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.
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
Commissioning
(first 48 hours of use)
Due to the newness of materials, the heater will
produce a slight smell for the first 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 first 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.
Control Functions
Setting the Controls
The controls are located at the top right hand
corner of the heater, both under the hinged flap,
and on the side panel.
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 4, the following evening if
the room is too warm reduce to 3 or if it is too cool
increase to 5. 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.
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.
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 first 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
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.
CLEANING
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 finishes 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
fitted to limit the extent of any wall discolouration.
