Installation

Pre-start-up checks

Burner start up simultaneously involves
starting up installation by the fitter or his
representative; only they can guarantee
boiler house compliance with currently
accepted practices and regulations in
force.
The fitter must first be in possession of
a " certificate of gas fuel conformity "
issued either by the approved body or
distributor and also have leak-tested
and drained pipework upstream from
the quarter-turn hand-operated valve.
Pre-start-up checks
· Check:
– nominal voltage and electrical
frequency available and compare
with those indicated on the rating
plate,
– polarity between phase and
neutral,
– connection of previously tested
earth wire,
– absence of potential between
neutral and earth,
– direction of rotation of motor,
· Turn off the power supply.
· Check absence of voltage.
· Close the fuel valve.
· Take note of the operating
instructions provided by the boiler
and regulator manufacturers.
· Check:
– that the boiler is filled with
pressurized water,
– that the circulator(s) is/are
working,
– that the valve(s) is/are open,
– that the combustion air supply and
exhaust flue are operational and
compatible with the heating
capacity of the burner and the fuel,
– presence, calibration and setting
of electrical protection devices,
– setting of boiler regulator circuit,
– fuel-oil level in tank,
– that the suction line is full,
– position of the flexible piping:
suction and return,
– boost pressure of 2bar max.,
– position of hydraulic protection
valves and preliminary filter.
