Description of the appliance
The GITRÈ LN boiler is an oil fuelled hot water boiler capable
of low temperature functioning. GITRÈ LN versions are designed
only for central heating applications. The GITRÈ B/100 LN version
is equipped with a 100 litre vitrified storage cylinder and can
be used for central heating and domestic hot water production.
The cast iron boiler body features a triple flue pass design and a
horizontal combustion chamber.
The front cover opens fully to facilitate the inspection, mainte-
nance and cleaning of internal parts and to minimise service
time.
The boiler body is covered in high density glass wool insulation
to reduce heat loss.
The boiler is fitted with a single stage, low NOx, fuel oil burner.
The GITRÈ LN boiler's control logic incorporates a total shutdown
function to minimise energy consumption:
− The GITRÈ LN (heating only) model only starts up if the
central heating system requests heat (i.e. when the room
thermostat switches the heating on);
− If the GITRÈ B/100 LN (heating and DHW) model is in
"Summer" mode ("Summer/Winter" selector turned to
Summer position), it only starts up to restore the setpoint
temperature of the water in the storage cylinder. If it is
in "Winter" mode ("Summer/Winter" selector turned to
Winter position), it starts up either in response to a re-
quest for heat from the heating system (i.e. when the
room thermostat switches the heating on) or to restore
the setpoint temperature of the water in the storage
cylinder (DHW heat requests are prioritised over central
heating requests)..

Safety and control devices
GITRÈ LN boilers incorporate the following safety and control de-
vices:
− A manual reset safety thermostat that forces a safe-
ty shutdown if boiler temperature exceeds the safety
threshold (110°C). The sensor used to monitor this tem-
perature is located on the body of the heat exchanger;
− A minimum temperature thermostat that enables the
central heating pump only if boiler temperature exceeds
the minimum permissible (50°C);
− An electronic burner controller that monitors the correct
functioning of the selected burner program and sends
a lockout signal to the control panel in the event of an
error.
ONLY FOR GITRÈ B/100 LN MODELS
− A maximum temperature thermostat that shuts down
the burner if boiler temperature reaches or exceeds the
default maximum limit ( 82°C) during the heating of do-
mestic hot water in the storage tank;
− A heat dissipation thermostat that starts up the storage
tank pump to dissipate excess heat in order to keep boil-
er temperature below the safety threshold (90°C).

The intervention of a safety device indicates a potentially
dangerous malfunction in the system. Contact the manu-
facturer's Technical Assistance Service immediately.
9
Safety devices must only be replaced by the manufacturer's
Technical Assistance Service using original spare parts. Refer
to the spare parts catalogue supplied with the boiler.
0
Do not use the boiler if any of its safety devices are faulty.
Always check that the boiler is functioning correctly after repairs
have been made.
