INSTRUCTIONS LFL 1.... CONTROL BOX
Control box for burners of average and high power, with forced
draught, intermittent service (*), 1 or 2 stages, or modulating
types, with supervision of the air pressure for controlling the
air damper.
This control box bears the EC mark, in accordance with the
Gas and Electromagnetic Compatibility Directive.
* For reasons of safety, it is necessary to make at least one con-
trolled stop every 24 hours!
As regards the standards
The following LFL1… features exceed the standards, offering
a high level of additional safety:
- Theflamedetectortestandfalseflameteststartimmediatelyafter
the tolerated post-combustion time. If the valves remain open, or
do not close completely after adjustment stops, a lock-out stop
is triggered at the end of the tolerated post-combustion period.
The tests will end only at the end of the pre-ventilation time of
the next start-up.
- Thevalidityofworkingoftheflamecontrolcircuitischeckedeach
time the burner starts up.
- The fuel valve control contacts are checked for wear during the
post-ventilation time.
- A built-in fuse in the appliance protects the control contacts from
any overloads that may occur.

not position the air damper at the points described, the burner
