1.0 Genera Information
2.0 Fixing
LST radiators are for use on indirect systems only. The system
should be designed to follow the recommendations of BS5449
or BS6880, as appropriate, with particular care taken to avoid
air entry or water discharge through an open vent. The
installation work must be done in accordance with recognised
good practice and precautions taken to avoid contamination,
which could lead to corrosion. If a corrosion inhibitor or other
water treatment is to be used, the manufacturer’s instructions
must be strictly followed.
lA pair of templates are supplied with the product to ensure the correct positioning of the wall brackets for the emitter
and the enclosure (see fig. 1).

IMPORTANT: It is advisable to leave a further 5mm
clearance above any final floor covering to allow for
easy fitting and removal.
3.0 Water Connections
lIf surface mounting pipework is being used, this must be
routed and mounted to run within the rectangular cut-outs
provided at each end of the enclosure. To remove the
cut-out, flex from side to side until the connection is broken.
If pipework enters one side only, the other cut-out should be
left intact.
lCarry out the plumbing connections in the usual way. Fig 1
shows the clearances between the heat emitter and the
enclosure. Ensure that pipework and valves are within these
limits to enable correct fitting of the enclosure.
LST radiators may be fitted with the following types of thermo-
static radiator valves:

lRemove both security screws.
lLift the LST enclosure out of the wall bracket slots and pull
forward.
lTo reposition the enclosure, lift the enclosure onto the
brackets ensuring correct engagement with the bracket slots.
Replace the security screws.
lIf the unit is fitted with a Close Coupled or Remote TRV kit
then excessive movement of the casing will be restricted by
a safety chain.

IMPORTANT: For the correct installation of radiators it is essential that the fixing of the radiator is carried out in such a way
that it is suitable for intended use AND predictable misuse. A number of elements need to be taken into consideration
including the fixing method used to secure the radiator to the wall, the type and condition of the wall itself, and any additional
potential forces or weights that may happen to be applied to the radiator, prior to finalising installation.

6.0 Fu Fitting Instructions
1. Position the LST
lDecide upon the final wall position for the LST radiator to
be fitted.
lPosition the LST enclosure against the wall and mark the
position of each end (see fig. 2).
2. Distance from f oor
lReferring to the supplied template, measure and mark the
correct distance from the floor allowing for any floor covering
(see fig. 3).
Fig. 2
Fig. 4
Fig. 3
3. Fixing bracket positions
lCut the template as indicated and position each half in the
required position, aligning for both height and width.
lThrough the template mark and drill the lower bracket fixing
points (see fig. 4).
4. Fit the fixing brackets
lPlug the wall as necessary and fit the brackets to the wall
using the bottom fixing points. Ensure that the brackets are
90° to the floor and mark, drill and plug the upper fixing
points.
lSecure the brackets to the wall. Fit the plastic inserts to the
emitter brackets and the spire nuts to the enclosure brackets
(see fig. 5).
Fig. 6 Fig. 7
5. Fit and p umb the emitter
lMount the heat emitter onto the wall brackets.
lCarry out the water connections as for standard radiators,
ensuring that the pipework and valving will not effect the
fitting of the enclosure (see fig. 6).
6. Fit the enc osure
lFit the two self adhesive spacers to each back return of the
LST enclosure below the pipework knock-outs as shown
(see fig. 7).
lFit the LST enclosure on the wall brackets. Ensure the LST
enclosure is located into the mounting slots situated on top
of the brackets.
lSecure the LST enclosure to the brackets via the screw holes
at each end.
NOTE: Allow an additional 5mm
above any floor covering that is
likely to become wet, when
cleaning for example.
Enc osure Brackets:
Ensure protruding side of
bracket faces outwards.
Push a spire nut on to each
bracket over the bottom hole
with the flat side facing
outwards.
IMPORTANT: Ensure that the long side
of the brackets protrude for type 11
radiators, and the short side protrude
for type 22 radiators.
