Setting and checking safety devices
Q GAS
Gas pressure switch :
· Set to minimum distribution
pressure.
Burner is working with ignition flow.
· Slowly close ball valve.
Burner should stop due to insufficient
gas pressure.
· Reopen ball valve.
Burner restarts automatically.
The pressure switch is set.
· Fit and screw cover on.
Leakage controller : VPS.
For burners C160 and C210
· Open pa on VPS.
· Restart burner.
After 30s, VPS should lockout to safety
(red lamp on).
· Reclose pa.
· Press red indicator to release VPS
safety lockout.
The control cycle restarts.
Burner works.
· Check tightness.

Q GAS and FUEL OIL
Air pressure switch.
Burner is working with ignition flow.
· Look for air pressure switch cut-off
point (lock).
· Multiply value read by 0.8, in order
to obtain setting point.
· Restart the burner.
· Simultaneously disconnect both
microammeter cables.
Unit should immediately lockout.
· Refit measuring bridge and covers.
· Disconnect measurement appliances.
· Reclose pressure take-offs.
· Release cover.
Burner works on gas or fuel oil (both
are available).
· Select the other fuel via switch S4.
The burner stops... then restarts
with chosen fuel.
· Check the following :
– for any leaks between flange and
boiler front,
– that regulator circuit is open
(limiter and safety).
– the intensity setting on fan motor
thermal relay.
C120, C160 : 5,5A / 400V
C210 : 6,6A / 400V
Cell
· Test cell with simulated flame and
without flame.
· Check combustion in real operating
conditions (doors closed, cover on,
etc.), as well as for leaks in the
various circuits.
When GAS combustion tests are
validated, return to FUEL OIL.
· Check FUEL OIL combustion
values, which must remain
unchanged from initial setting.
· Note the results on the appropriate
documents and communicate them
to the dealer.
· Put into automatic operation.
· Distribute the information required to
operate the boiler.
· Place the boiler-room plate where it
can easily be seen.
