1.1 General Safety Information
9 This product must be installed by a legally qualied heat-
ing engineer. On completion of the installation, the install-
er must issue the owner with a declaration of conformity
conrming that the installation has been completed to the
highest standards in compliance with the instructions pro-
vided by Rin this instruction manual, and that it con-
forms to all applicable laws and standards.
9 This product must only be used for the purpose for which it
is designed and made, as specied by R. Rdeclines
all responsibility, contractual or other, for damage to prop-
erty or injury to persons or animals caused by improper in-
stallation, adjustment, maintenance or use.
9 The room where the boiler is installed must be proper-
ly ventilated to ensure a sufcient supply of air for correct
combustion.
9 If you notice any water leaks, disconnect the boiler from the
mains electricity supply and shut off the water supply.
9 The boiler must be serviced at least once a year.
9 Periodically check that pressure in the central heating cir-
cuit, when cold, is approximately 1.5 bar and below the
maximum limit specied for the boiler. If necessary, top up
through the lling cock or contact the RTechnical Assis-
tance Service or a qualied heating engineer.
9 If the boiler is not going to be used for an extended peri-
od of time, perform the operations described later in this
manual.
9 This manual is an integral part of the equipment and there-
fore must be stored carefully and must ALWAYS accompany
the boiler even if it is sold to another Owner or User or trans-
ferred to another plant. If it is damaged or lost, request an-
other copy from your local Technical Assistance Service R.
1.2 Precautions
The operation of any appliance that uses fuel, electrical power
and water demands that a number of fundamental safety pre-
cautions be respected:
0 Do not allow children or inrm persons to operate the sys-
tem unsupervised.
0 It is forbidden to use electrical devices or equipment, such
as switches, appliances, etc. if there is a smell of gas or un-
burnt products. If so:
−Ventilate the room, opening doors and windows
−Close the fuel shut-off cock.
0 Do not touch the boiler while barefoot or wet.
0 Never clean or service the boiler without rst disconnect-
ing it from the mains electricity supply by turning the mains
power switch and the control panel switch OFF.
0 Never pull, disconnect, or twist the electrical cables coming
from the appliance even if it is disconnected from the mains
electricity supply.
0 Do not obstruct or restrict the vents in the room where the
boiler is installed. Adequate ventilation is essential for cor-
rect combustion.
0 Do not expose the boiler to the elements. It is not designed
for use outdoors.
0 It is prohibited to leave inammable substances and con-
tainers in the room where the boiler is installed.
0 Do not dispose of packaging material into the environment,
or leave it within the reach of children, since it can become
a potential hazard. Dispose of packaging material in com-
pliance with applicable legislation.
0 It is forbidden to operate the boiler without water.

GENERAL INFORMATION
1.3 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 vitried storage cylinder and can
be used for central heating and domestic hot water production.
The cast iron boiler body features a triple ue 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 tted 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)..
1.4 Safety 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).
9 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.

USE
2 USE
2.1 Putting into service
Have the RTechnical Assistance Service start up your GITRÈ LN
boiler for the rst time. Once this has been done, the boiler can
be left to function automatically.
Under certain circumstances, such as after long periods of dis-
use, the user may need to re-start it without involving the Tech-
nical Assistance Service.
2.1.1 Preliminary operations
Perform the following checks before starting up the boiler:
−Check that the fuel shut-off cock and heating system
shut-off cock are open
−Check that the central heating circuit pressure gauge
shows a pressure over 1 bar with the system cold. Check
also that the circuit is properly de-aerated
2.1.2 Start-up
Once you have completed all the checks listed above, proceed as
follows to start up the boiler for the rst time:
ONLY FOR MODELS GITRÈ 4 LN-GITRÈ 5 LN-GITRÈ 6 LN
−Turn the boiler’s mains power switch ON
−Set the room thermostat to the required temperature (~
20°C) or, if the system has a timer or timer-thermostat,
make sure that this is switched “ON” and adjusted to the
required temperature (~ 20°C).;
−Open the control panel access door;
ONLY FOR MODELS GITRÈ 4 LN-GITRÈ 5 LN-GITRÈ 6 LN
−Turn the boiler thermostat to about the middle of the
section with three lines;

2.1.3 Ignition failure
If any ignition errors or malfunctions occur, the burner enters
“LOCKOUT”. This is shown by the red button light on the burner
and by the warning light on the control panel.

9 If a “LOCKOUT SHUTDOWN” occurs, wait about 30 seconds be-
fore resetting the burner.
2.1.4 Resetting the burner and safety thermostat
To restore normal startup conditions, open the protective cover
over the control panel and turn the function selector to posi-
tion (II) "Reset burner" for at least 1 second before returning it to
position (I). Wait for the burner to complete the entire ignition
cycle again, up to the ignition of the ame.

If boiler temperature becomes too high, the manual reset safety
thermostat trips.
9 No warning signal is given if the safety thermostat trips, but
the fact that is has tripped can be seen from the boiler tem-
perature gauge (T>110°C).
