Pre-startup check
General regulations applying to gas
supply
· The gas-valve assembly MUST be
connected to the gas supply network
by an authorised service engineer.
· The cross-section of the gas conduit
should be of a size designed to
guarantee that the gas flow pressure
does not drop below the specified
level.
Pre-startup check
The following tests and checks must be
carried out before the burner is used for
the first time.
Operating specifications of the boiler
–
manufacturer
Adjustment of:
–
– temperature controller
– pressure controller
– limiting device
– safety switch
gas input pressure min. 20mbar flow
–
pressure
correct sealing of gas-bearing
–
elements
purging of fuel-bearing conduits
–
unobstructed exhaust conduits,
–
sufficient supply of fresh air
Direction of rotation of the ventilation
–
motor (see arrow on the body of the
burner).
The act of startup places the system
under the joint responsibility of the user
and the fitter engaged to carry out
installation, or the latter's
corresponding legal representative.
Only the authorised fitter can guarantee
that the system conforms to relevant
standards and regulations.
The fitter should be in possession of
the corresponding official permit, and
should carry out the corresponding leak
tests and purging of the system.
All electrical installation and
connection work MUST be carried
out by a suitably qualified service
engineer. VDE and EVU (RGIE-AREI
for Belgium) rules and regulations
must be observed when doing so.
Electrical connection
· Check to ensure that the power
supply is as specified (230 V, 50
Hz)
Burner fuse rating: 10A
Electrical plug connection
The electrical plug-and-socket
connection, burner and heat generator
(boiler) are linked via one 7P. and one
4P. plug-and-socket connection.
The connection cable is fed through the
connection clamp and secured. Insert
connection cable for gas valve through
the clamp and into the gas valve.
Testing of burner program
sequence before releasing gas for
first time
· Close ball valve upstream of gas
valve assembly.
· If gas pressure upstream of valve
assembly is insufficient, bypass the
gas pressure switch (terminal 2 and
3) if necessary, shutting down the
power supply to the burner.
· Activate the boiler to start up the
burner, and check the program
sequence.
· The blower runs with a delay that
depends on the adjustment setting
of the control unit.
· Pre-ventilation time (54s)
· Pre-ignition time (3s)
· Open solenoid valves
· Safety period (3s)
05/2005 - Art. Nr. 13 018 114A
Burner motor connection
The burner is delivered for a power
supply of 400V - 50Hz of triphase
current with neutral and earth.
Pass the burner motor connection
cable in the flange, and connect to the
terminal.
Check the direction of rotation of the
ventilation motor (see arrow on burner
body) manually with the burner
contactor.
· Fault shutdown after expire of safety
period, with blocking of control unit
(fault indicator lamp lights up)
· Shut off power to burner by
disconnecting electrical supply, and
remove any bypass connection fitted
to the gas pressure switch.
· Reconnect electrical power supply.
· Press button R to reset control unit.
