are only active if the main switch of the unit is
in the "I" position and the unit is connected to
the power mains.
To ensure that these protection devices remain active,
switch your gas-fired condensing boiler on and off using
the controller (see the corresponding operating manu-
al).

densing boiler out of operation.
