GENERAL REQUIREMENTS
3.1 Related documents
It is important that all gas appliances are
installed in accordance with the rules in force
and by appropriately qualified persons.
Failure to install appliances correctly could
lead to prosecution. It is in your own interest
and that of safety to ensure compliance with
the law.
3.2 Heater location
The location chosen for the air heater must
permit the provision of a satisfactory flue
system venting to outdoor atmosphere and
adequately ventilated to provide for
combustion air. The location must also
provide sufficient space to allow the heater to
be serviced.

Height from floor to bottom surface of heater. These
are recommendations only. Positioning of heaters
depends on application.
Air heaters should, where ever possible
always be installed to blow toward or along
external wall surfaces. Where two or more air
heaters are installed in the same room, a
general scheme to ensure continuous air
circulation should be maintained for best
results. Suspended heaters are most
effective when located as close to the
occupancy zone as possible, this fact should
be born in mind when determining the
mounting heights to be used. Care should be
exercised to avoid directing warm air directly
onto the occupants. Partitions, columns,
counters, storage racking, etc. should be
taken into account when choosing the
location so that an unobstructed path for the
air circulation can be maintained.
Where air heaters are located in the center of
the space to be heated, the air should be
discharged toward outside walls. In large
areas, they should be located to discharge
air along outside walls with additional
heaters provided to blow air into the center of
the area.
In places where infiltration of cold is
excessive, such as entrance doors it is
desirable to locate a heater so that warm air
is discharged directly toward the source of
cold air from a distance of 4,5 - 6,0m
Air heaters should not be installed in
corrosive atmospheres, i.e. near
plating or degreasing plants or in
areas where there is a fire risk.
Do not locate the air heater where it
may be exposed to water spray, rain,
etc.
3.3 Combustion air supply & flue
system
The air heater may be installed as a
balanced flue (Type C) heater requiring both
a combustion air inlet duct and a flue pipe or
as a power vented (Type B) heater, which
requires only a flue pipe exhausting to
outdoors. All products of combustion must be
flued to outdoor atmosphere.
