Operating Instructions For TD/TAD4 Dual Fuel Burner
June 13 24 of 165 TD/TAD4 Manual Rev 4
Warning:
Touching the electrical parts may be fatal – even after the equipment has been
disconnected from mains.
Also make sure that other voltage inputs have been disconnected, such as
load-sharing (linkage of DC intermediate circuit), as well as the motor
connection for kinetic back-up.
Before touching any electrical parts, wait at least: please consult the inverter
manual.
5. Turn pump slow until all air has been vented both from the pump itself and the burner
pipework, and the system is fully flooded.
6. The pump can now be put into operation.
2.5 Gas installation
Note: The national or other standards in countries to which the burner may be exported to must be
identified and adhered to.
2.6 Electrical connections
All electrical installation work must be carried out in accordance with the I.E.E. wiring regulations
17th Edition 2008, with further reference to the Health and Safety Executives `Memorandum of
Guidance on the Electricity at Work Regulations 1989 ( H.S.E. Booklet HS[R]25 )
Take note of the I.E.E. requirement for bonding main gas supply pipework to earth.
Connections to all terminals and the appliance should be made in accordance with the wiring
diagram supplied with each burner.
The final part of the electrical cable run must be made in flexible conduit, long enough to enable
the appliance door to be opened.
Ensure that the mains electrical supply to the burner is protected by a suitably sized fuse.
Connections to all terminals and the appliance should be made in accordance with the wiring
diagram supplied with each burner, using suitable fixed wiring installation (incorporating means of
disconnection) in accordance with local and national wiring regulations.
2.7 Inverter Connection
Burner motor connections can be found in dedicated aluminium enclosure situated on the side of
the burner control panel. Wiring diagram shows how to connect the inverter to this enclosure. The
earth leakage current from the frequency converter exceeds 3.5mA. To ensure excessive leakage
current conforms to EN/IEC 61800-5-1, an earth wire of at least 10mm
2
or two separate earth
ground wires are used.
2.8 Ventilation requirements
In all cases, gas installation work must be carried out by approved members of
Gas Safe
All relevant standards of The British Standards Institute, IGEM Standard's
and the equivalent European Standards must be adhered to.
