2. Installation.
I
t is strongly advised that the installer reads Section 1 of
this manual prior to starting any installation work. It is a
requirement that only qualifi ed and competent personnel
undertake installation, commissioning, and servicing.
Warning
Always ensure that the appropriate personal protective
equipment is used.
2.1
Packaging/siting
The heater will usually be supplied wrapped in heavy gauge
polythene, non assembled parts will be supplied separately.
Prior to installation, the assembly of the heater should be
completed, it is advisable that this is undertaken in the area
where the heater is scheduled to be sited.
Caution
The Heater must be installed within the mounting heights
indicated below in metres.
The following clearances in mm must be observed *when
suspended:

Heater Mounting
The heater and fl ue must be adequately supported by one of
the following methods;
•
Suspension by steel drop rods or straps from the M10
fi xing points located on top of the heater. These must be
of suffi
cient strength to safely carry the weight of the unit
and ancillary equipment. The straps may only drop
vertically to eyebolts, if used; I.E. They must not be joined
to the eyebolt at an angle to the vertical, and eyebolts, if
used, should be of an approved type.
•
OUH heaters can be mounted on specifi cally designed
cantilever wall or vertical stanchion brackets which locate
directly to the four M10 fi xings on the heater casing.
Alternatively OUHA or OUHC units can be mounted on
cantilever type wall brackets however consideration must
be given to ensure that the bracket is large enough to
support the heater whilst providing the necessary
clearances.
In either case the installer should ensure that the wall wall
fi xings or other support medium is capable of supporting
the weight
•
On a level non-combustible surface capable of
adequately supporting the weight of the unit and
ancillary equipment .

recommended when installing the heater.

Warm Air Circulation
The air heater should be positioned to enable maximum
circulation of discharged warm air within the area to be
heated, whilst taking account of personnel within the area,
sources of cold air ingress, and obstructions.
Caution
Ensure louvres are adjusted outwards and ensure blades are
not resonating
The air temperature rise on passing the heat exchanger is
typically around 34°C
A full and unobstructed return air path to the air heater must
be provided (see 1.11 Air Supply).
Where the heater is positioned to deliver blown air through an
opening in a wall, return air intakes should be located so that
they cannot become blocked. Similarly these intakes must
be positioned so as not to draw in odours, fumes, hazardous
vapours or particles.
