Burner Start-Up; Burner Ignition - Riello RS 25/M BLU Installation, Use And Maintenance Instructions

(A)
In the event of a burner lockout, more than two consecutive burner reset opera-
tions could cause damage to the installation. On the third lockout, contact the Af-
tersales Service.
If further lockouts or burner faults occur, interventions must only be made by
qualified, authorised personnel (as indicated in this manual, and in compliance
with the laws and regulations currently in force).

BURNER START-UP

Switch off the remote controls and place the
switch 1)(A) in position "MAN".
As soon as the burner starts, check the direction
of rotation of the fan blade, looking through the
flame inspection window 17)(A)p.4. Make sure
that the lamps or testers connected to the sole-
noids, or pilot lights on the solenoids them-
selves, indicate that no voltage is present. If
voltage is present, stop the burner immediately
and check the electrical connections.

BURNER IGNITION

Having completed the checks indicated in the
previous heading, ignition of the burner should
be achieved. If the motor starts but the flame
does not appear and the control box goes into
lockout, reset and wait for a new firing attempt. If
ignition is still not achieved, it may be that gas is
not reaching the combustion head within the
safety time period of 3 seconds. In this case,
increase gas ignition delivery. The arrival of gas
to the pipe coupling is shown by the pressure
gauge (C) p.10. Once ignition has taken place,
proceed with global calibration operations.
