BURNER USE
E
Burner operation is fully automatic.
N
the burner is started by closing the master switch
and the control panel switch. Correct burner ope-
G
ration is regulated using the command and control
devices, as described in the chapter "Operation
L
description". The "lock" position is a safety position
that the burner automatically assumes when a bur-
I
ner or system component is not working properly.
The burner may stay in the lock position without
S
any time limits. Locks may also be caused by tem-
porary inefficiencies. In this case, the burner will
H
restart normally.
It is recommended to check for anomalies in
the heating plant before restarting the bur-
ner. To release it, press the release button.
If locking continues to occur (3-4 times), do not con-
tinue with the operation. Check that the fuel arrives
normally to the burner and ask for assistance from
the after-sales service in your area.
