Always provide a minimum
clearance of 600mm at an open air
intake (inlet side)
Four-point suspension is possible from the
Ø11.0 mm holes provided in the base frame
using drop rods etc.
Ensure that suspension fixings are lock nut
secured to secure against loosening. When
suspended, the air heater should be rigid so
as to avoid placing a strain on the flue system
and connected services.

framework is a one-part construction)

When installing, ensure the complete unit will
not jeopardize or compromise the integrity of
the building security.
A distance of 500mm must be maintained
between the deck on which the appliance
is installed and any air inlet provided to the
burner.
The location where the unit is to be installed
must allow sufficient space around the heater
for servicing and to allow the flue products to
escape freely.
A minimum distance of 1500mm must
be maintained on the controls side of the
appliance for access and maintenance.
When installed at ground level the entire
installation should be protected by a fence
to guard against damage and to protect the
public from possible injury.
Ensure that the structural elements which will
be used to support the appliance are adequate
to carry the weight of the appliance and its
ancillary components i.e. the ductwork system.
Ensure that the air heater is installed in a level
plain and that the surface onto which it is
installed is vibration free.
The air heater must be fastened securely to
any base mount frame work. Roof-curbs are
manufactured from galvanised mild steel and
should be fixed prior to siting the appliance.
It is necessary to provide weatherproof seals
between the appliance and the structural
elements of the building. Exposed ducting
should be insulated and covered with a
weatherproof membrane.
The duct connection to the appliance should
be made using flexible connections to reduce
noise transmission and allow for thermal
expansion of the air heating module.
When siting the appliance and unloading,
extreme care must be exercised to ensure
that the slings etc. employed do not damage
the casing. The weatherproofing will become
unsealed should any damage be sustained.
Sling spreaders must be used to provide
clearance between the appliance and the
slings. Figure 3 shows the location of spreaders
and slinging points provided for this purpose.
Use all available sling points
