INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS FOR
Twin-Zone Radiant Heater
Catalogue Number HE6351 1.5 kW
PLEASE RETAIN THIS LEAFLET FOR FUTURE MAINTENANCE
IMPORTANT
1. The two elements are rated at 120 volts and connected in series to give 1.5 kW at 240 V AC.
2. The silica sheath of the heating elements should not be touched by hand, otherwise permanent marks (devitrification) will
occur during heating. Should the element position need to be changed (to alter the beam width), handle only by the
ceramic bushes at the ends, and observe the cleaning instructions afterwards.
ELEMENT POSITION
The Twin-Zone heater is designed to provide alternatively widespread warmth (broad beam) or a more concentrated beam of
heat over a localised area (narrow Beam), and the selection of either is made by adjusting the position of the element. This is
determined by ensuring that the ceramic blocks supporting the silica tubing are mounted into the heater body in the correct
position. Long end of ceramic blocks downwards will give narrow beam and short end downwards will give broad beam.
ASSEMBLY (as Fig. 1)
The heater is supplied with the elements fitted in the
broad beam position and connected ready for
installation.
To change the beam width to the narrow setting
Remove the terminal box covers.
Remove the reflector from the body of the heater.
Disconnect the element tails from the terminal
blocks.
Holding the elements by the ceramic bushes, lift the
element out of the retaining slots in the body.
Rotate the ceramic blocks into the narrow beam
position (long end downward, as Fig. 2) and
replace.
The heater can now be reassembled in the reverse
order.
ENSURE THAT THE CERAMIC BLOCKS ARE ALL
INSERTED INTO THE BODY IN THE SAME
OFFSET POSITION. LONG END DOWNWARDS
FOR NARROW BEAM.
WIRING DIAGRAM (Fig. 3)
The wiring diagram is shown in Fig 3 and indicates
the manner in which the two 120 volt elements are
connected in series for 240 volt operation.
The heater is suitable for connection to 230/250
volt, single-phase supply and should be wired to
heat resisting cable suitable for a continuous
ambient temperature of 750C, in accordance with
IEE Regulations for the Equipment of Buildings.

SUSPENSION
Mounting brackets for suspension purposes are supplied
with each heater. See diagrams below for alternative
methods. Provision is made for mounting by 20 mm
conduit.
HORIZONTAL (See Fig. 4)
ANGLED
Fig. 5 illustrates a pair of heaters, which should be adjusted
to the narrow beam position, suspended from the ceiling.
Two heaters can be mounted at 45 degrees to the vertical,
thus giving wider radiation from a single point and saving
extra wiring.
WALL MOUNTING
The heater can be wall mounted, using the brackets shown
in Fig. 6.
A safety guard, Catalogue No HE6352, is available if
required for particular applications.
SPECIAL NOTE
Heaters must always be mounted with elements in the
horizontal plane.

CAUTION
Where radiant heaters are used in the presence of any
combustible materials, ensure that such materials cannot
be overheated by radiation. These heaters are not flame
proof and should not be used in the presence of paint
solvents or petrol fumes.
MAINTENANCE
Cleaning: Remove the reflector for occasional cleaning
with a damp cloth to maintain maximum reflectivity, and
wipe the element tubes carefully with a clean cloth
moistened with methylated spirits. If the reflector is very
dirty clean with metal polish.
ELEMENT REPLACEMENT
A complete set of replacement elements is available for the
heater. Each set consists of 2 x 120 volt 750 watt element
spirals assembled into the silica tubes complete with
ceramic bushes.
When installing replacement elements the cleaning
instructions given above should be observed.
Details of the replacement elements are:
