IMPORTANT

The burners have been approved for intermittent
operation. This means that they must stop once
every twenty four hours to permit the electrical
control box to check its efficiency at start up. Nor-
T R
mally the boiler's limit thermostat (TL) ensures
the stopping of the burner.
If this is not the case, it is necessary to apply in
series with the (TL) a timer switch that turns off
X P4

operation by opening the connector (CN1) in-
serted in the probe's red wire, located outside
the control box.
