GENERAL INFORMATION
1.3
Description of the appliance
The
GITRÈ
boiler is an oil fuelled hot water boiler capable of low
temperature functioning.
GITRÈ
versions are designed only for
central heating applications. The
GITRÈ B/100
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 oil burner.
The
GITRÈ
boiler's control logic incorporates a total shutdown
function to minimise energy consumption:
− The
GITRÈ
(heating only) model only starts up if the cen-
tral heating system requests heat (i.e. when the room
thermostat switches the heating on);
− If the
GITRÈ B/100
(heating and DHW) model is in "Sum-
mer" mode ("Summer/Winter" selector turned to Sum-
mer position), it only starts up in response to a request for
domestic hot water. If it is in "Winter" mode ("Summer/
Winter" selector turned to Winter position), it starts up
either in response to a request for heat from the central
heating system (i.e. when the room thermostat switches
the heating on) or in response to a request for domestic
hot water. (DHW heat requests are prioritised over central
heating requests.).

Safety and control devices
GITRÈ
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 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.

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.
