Faults / Solutions

Here below you can find some causes and the possible solutions
for some problems that could cause a failure to start or incorrect
operation of the burner.
A fault usually makes the lockout led signal which is situated in-
side the reset push-button of the control box.
When the lockout lamp comes on, the burner will only attempt to
start up after the reset button has been pressed. If ignition is then
normal, the stop can be attributed to a temporary fault that is not
dangerous.
If however the lock out continues the cause must be determined
and the solution found.
Faults
The burner does not
start when there is heat
demand.
The burner goes into
lockout mode before or
during the pre-purging.
Burner runs normally in
the pre-purge and igni-
tion cycle and locks out
after 5 seconds ca.
Burner starts with an ig-
nition delay.
The manufacturer cannot accept responsibility for
any damage to persons, animals or property due
to error in installation or in the burner adjustment,
WARNING or due to improper or unreasonable use or non
observance of the technical instruction enclosed
with the burner, or due to the intervention of un-
qualified personnel.
