It is advisable to check all pipe work prior to installation to ensure that there is no loose debris or scale present.
Black iron pipes can be hammered to assist in the removal of these contaminants.
The oil feed to each heater must be fitted with a fire check valve and isolating valve.
Any waste oil or sludge must be disposed of correctly.
CAUTION
The fire check valve must be operated by way of a fusible link positioned so that it is above the burner.
WARNING
Never dispose of it by dumping or tipping it down drains or into watercourses where ground water can become
polluted and environmental damage caused.
1.10 Electrical supply
Wiring external to the Suspended Oil fired Unit Heater must be installed in accordance with any local, national, and
European regulations, as well as meeting the appropriate requirements of IEE regulations.
CAUTION
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.(as per BS5991 clause 20.2).
The Control fuse ratings are detailed on the appliance data plate.
WARNING
Ensure that the electric and oil supplies are turned off before any electrical work is carried out on the heater.
CAUTION
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.
WARNING
All connections must be checked to ensure that they are secure, and free from corrosion.
Terminals and connections should also be checked to ensure that no stray strands are bridging terminals.
CAUTION
Final connections for any additional external controls must be completed on site, and must be carried out
according to IEE regulations.
Separate user information is provided for the time control unit and the burner, and forms part of the product
information pack which accompanies every heater when despatched.
WARNING
All heaters are supplied fused and pre-wired, all must be earthed.
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, when the heat exchanger has been allowed to cool
sufficiently to prevent any damage from occurring. Claims for damage will not be considered if they have
resulted from incorrect wiring or the incorrect use of the heater.
WARNING
Always ensure that the appropriate personal protective equipment is used.
