5. 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
6. 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 fi xing kit.
7. 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 fi rm
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 fi rmly on the fl oor.
8. 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.
9. 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.
10. Remove one element to allow access
for the back rows of bricks. On the FXL24i
remove the element to the right of centre and
on the FXL18i 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.
11. Carefully fi t the bottom row of the back
layer of bricks placing the two end bricks
into position fi rst. 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.
Refi t 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.
12. Fit the front layer of bricks with the
recess toward the front of the heater.
The complete core will comprise:
FXL18i : 3 x 4 brick columns
FXL24i : 4 x 4 brick columns
13. 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.
14. 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.
4. The heater is fi tted with a fan inhibitor
relay. This relay will inhibit the operation of
the fan during the off peak periods. If the fan
operation is required (eg. if using external
fan/boost timer) during the off peak period
then the relay switch should be switched to
the relay off position.

(relay ON position)
Relay OFF position
Four fi xing positions must be chosen for
the FXL24i and three for the FXL18i. Mark
the positions for the fi xing 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 fi xings previously
described. Secure the wall bracket to the wall
using the correct fasteners.
