1.4 Health and safety
Due account should also be taken of any
obligations arising from Health and Safety
regulations or relevant codes of practice.
In addition the installation must be carried
out in accordance with national or local
regulations and any other relevant Codes of
Practice by a qualified installer. Isolate all
electrical supplies to the heater & controller
before proceeding.
For your own safety we recommend the use
of safety boots and leather faced gloves when
handling sharp or heavy items. The use of
protective eye wear is also recommended.
Before using this appliance:
• Check that the voltage indicated on the
type plate corresponds to the mains supply
voltage.
• Ensure that the heater has been securely
fastened in its final mountain position.
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 posi-
tion 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 circu-
lation, 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-combus-
tible 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 appli-
ance, 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 installa-
tion, commissioning, servicing, or use, will
jeopardise any applicable warranty. More-
over, such a situation could also compromise
the safe and efficient running of the appli-
ance 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
warm air.
• The position of the heater relative to the
route of the flue
• The position of the heater relative to the
supply of fuel
• The position of the heater relative to the
electrical services, and if appropriate, any
additional controls.
• The position of the heater relative to the
supply of fresh air
• The height if applicable at which the
heater is to be mounted and potential
stratification /circulation problems.
• The position of the heater relative to
service and maintenance requirements
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.
