1. General information

This manual is an integral part of the heater,

therefore it should always be carefully kept
and it should always be provided together

with the heater, if it is transferred to another

owner or user. If this manual is damaged
or lost, a new one should be requested
from the installer or from the manufacturer.

After unpacking the product, please check

the contents to ensure all components are
present. If not, please contact your supplier.

The installation must be carried out by

suitably qualified personnel who, at the end
of the work, will commission the appliance
and issue to the owner a copy of the commis­sioning report, which also confirms that the
installation is carried out in accordance

with regulations & standards applicable to

the country of use and in accordance with
the manufacturers instructions.

This appliance has been manufactured

specifically for room heating and must be
used for this purpose. Contractual liability
of the manufacturer in respect of damages
caused to people, animal or premises by
incorrect installation, settings, maintenance
or by improper use of the heater is excluded.
During the initial start-up, there may be the
formation of odours and fumes due to the
evaporation of the oil added to protect the
heat exchanger during storage; this is normal
and will disappear after a short period. It is
recommended to suitably ventilate the room.

If the appliance is to remain unused for long periods,
it is recommended that the following operations
are carried out:

• Turn the appliances' electrical supply off
via the local isolator.

• Close the main fuel supply valve

If there is a long period of time between oper­ation, it is recommended that you contact

your installer to carry out the new start-up.

The heater shall be fitted with approved

accessories only. The manufacturer is not
liable for damages arising from the improper
use of the heater or from the use of non-orig­inal materials or accessories. References to
Laws, Regulations, Directives and Tech­nical Rules mentioned in this manual are
provided only for information purposes
and are in force when the manual is printed.

The entry into force of new provisions

or amendments to current laws does not
represent an obligation of the manufacturer
towards third parties. Repairs or main­tenance are to be performed by trained
personnel only. Do not modify or tamper

with the appliance, the manufacturer will

not be held responsible for any third party
modifications to the heater. The services
that are to be connected (fuel pipes, power

supply, etc.) must be suitably secured and
must not be dangerous with the risk of
tripping.

The manufacturer is responsible for the
product compliance with Laws, Directives
or Construction Rules in force when the

1.5 Location/Positioning

WARNING

The oil variant of the heaters must be
installed in accordance with the current

OFTEC regulations for oil fired products.

WARNING

Under no circumstances should any item

be placed on or above any part of the
heater, whether it is being used or not.

WARNING

All basic criteria must be satisfied prior to
commencing the installation and commis

-

sioning process. The Warm Air Heater must

be positioned and installed to comply with
all relevant standards and guidelines. And
should also meet the local and national fire

regulations and insurance criteria, this is
critical if the heater is to be installed within
a special risk area (e.g. being; within close

proximity to where petrol engined vehicles
are stored or parked, where cellulose spray-

ing takes place, where woodworking

machinery is being operated, etc,).

CAUTION

The heater must not be installed within an
area with unsuitable conditions, e.g. where
the atmosphere is highly corrosive, has a

high degree of salinity, or where high wind

velocities may affect burner operation.

CAUTION

Suitable protection should be provided for
the appliance when it is located in a posi­tion where it may be susceptible to
external mechanical damage; for example,
fork lift trucks, overhead cranes etc.

Indirect heaters must not be located in
hazardous areas, however, it is permissible
for the heater to supply air to such areas.

The heater must not be installed within an

environment where there is a high concen

­tration of chlorides, fluorides, salts, or other
aggressive or volatile chemicals/compounds.
Nor should the heater be positioned where
the burner could be adversely affected by
high winds or draughts.

The location chosen for the heater must allow

for the fitting of an effective flue system.

The location must also allow for adequate

clearance for the air supply, return air circu­lation, gas supply and electrical supply,
whilst also providing good and safe working
access. The heater must be installed on a flat
and level surface made from non-combus­tible material, which is sufficiently robust
to withstand the weight of the heater and
any ancillary equipment.

1.6 General requirements

WARNING

Unauthorised modifications to the appli­ance, or departure from the manufacturers
guidance on intended use on recommended
practices may constitute a hazard. To ignore
the warning and caution notices, and
advice from the manufacturer on installa­tion, commissioning, servicing, or use, will
jeopardise any applicable warranty. More­over, such a situation could also compromise
the safe and efficient running of the appli­ance itself, and thereby constitute a hazard.

WARNING

All heaters must be earthed.

The installation of the appliance must meet

all the relevant European, national, and
local criteria.

Prior to installation the following points should
be considered;

• The position of the heater for the optimum
efficient distribution and circulation of

1.7 Electrical supply

CAUTION

Ensure the fuel supply is in accordance with
the manufacturer’s recommendations and
is as stated on the appliance data plate.

CAUTION

The main electrical supply must not be
switched off or disconnected as a method
for stopping the heater, the exception to
this is in an emergency, or during servicing,
where the heat exchanger has been given
sufficient cooling time to prevent damage
from occurring. Claims for damage will not

be considered if they resulted from incor-

rect wiring or incorrect use of the heater.

Wiring external to the cabinet heater must

be installed in accordance with any local,
national, and European regulations.

The means of connection to the main

electrical supply must allow for complete
electrical isolation of the heater, furthermore,
in the case of a unit wired for a three phase
supply, the supply should only be used to
serve the heater itself and no other plant or
equipment.

The position of the isolation switch must

be such that it is adjacent to the heater and
easily accessible at all times. In addition, the
isolator itself must have a contact separation
of not less than 3mm.

The Control fuse ratings are detailed on the

appliance data plate.

WARNING

Ensure that the electric and gas supplies
are turned off before any electrical work

is carried out on the heater.

Ensure that wiring cannot make contact

with any surfaces liable to be subject to

high temperatures or where the insulation
of the wiring could be impaired as a result
of such contact.
