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:

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.

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
