Installation
Heater location
Flue requirements may affect
the location of the heater. Refer
to the "Combustion air supply /
flue arrangement" section before
making a final determination.
The flue pipe and accessible heater
surfaces will be hot under normal
operation and will cause burns if
touched. Suspend the heater such
that these components cannot be
touched.
For best results, the heater should be placed
with certain rules in mind:
• Always ensure that the minimum clearances
detailed previously are maintained.
• When possible, heaters should be arranged
to blow toward or along exposed wall
surfaces.
• Suspended heaters are most effective when
located as close to the working zone as
possible, but care should be exercised to
avoid directing the discharged air directly on
to room occupants.
• Partitions, columns, counters or other
obstructions should be taken into
consideration when locating the unit heater
so that a minimum quantity of airflow will
be deflected by such obstacles.
• When unit heaters are located in the centre
of the space to be heated, the air should be
discharged toward the exposed walls.
• In large areas, unit heaters should be located
to discharge air along exposed walls with
extra units provided to discharge air in
toward the centre of the area. For optimum
results heaters are best used in conjunction
with recirculating air fans suspended at high
level. Contact the manufacturer / distributor
for more details.
• At those points where infiltration of cold
air is excessive, such as at entrance doors
and shipping doors, it is desirable to locate
the unit so that it will discharge directly
toward the source of cold air, typically from
a distance of 4.5 to 6.0 metres. Alternatively,
air curtains can be installed. Contact the
manufacturer / distributor for more details.
Hanging the heater
Do not locate the heater where it
may be exposed to water or where
the ambient temperature exceeds
40°C.
Ensure that the structural elements,
which will be used to suspend
or support the appliance, are
adequate to carry the weight of
the appliance and its ancillary
components i.e. the flue system.
Unit weights are given in the
technical data section previously.
Sufficient space must be provided
around the heater for servicing and
clearances for safety.
Ensure that the unit heater is
installed in a level plane.
Always provide a minimum
clearance of 600mm at an open air
intake (inlet side)
Suspend the heater only from the
threaded nut retainers or with a
suspension kit provided by the
manufacturer.
Do not suspend the heater from the
heater cabinet panels.
Do not add additional weight to
the suspended heater.
The minimum safe mounting height
is 2.5 metres.
