3.0 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.

CAUTION:Air heaters should not be installed in corrosive
atmospheres, i.e. near plating or de-
greasing plants or in areas where there is a fire risk.

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.

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 - 6,0 meters.

CAUTION: Do not locate the air heater where it may be
exposed to water spry, 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.

Each heater installed as a type B appliance must be fitted with
an individual flue pipe and the combustion air inlet opening
must be provided with a protection grill (ask your AmbiRad
distributor for the appropriate protection grill (IP20) (1). Each
heater installed as a type C appliance must be fitted with an
individual combustion air/flue pipe system. Only systems
specified by the air heater manufacturer mat be used.

Common flue and combustion air systems must not be used
IMPORTANT: The flue must be installed in accordance
with national and local regulations. Failure to provide
proper fluing could result in death, serious injury and/or
property damage. The air heater must be installed with a
flue to the outside of the building. Safe operation of any
power vented gas apparatus requires a properly operating
flue system, correct provision for combustion air, and
regular maintenance and inspection.
