1 GENERAL SAFETY INFORMATION
This operation manual forms an integral part
of your new boiler. As such, it must be kept
safe and must always accompany the boiler.
If it becomes damaged or lost, request a copy
from the manufacturer’s Technical Assistance
Service.
b Your new boiler must only be installed
and serviced by qualified personnel, in
conformity to applicable legislation and
applicable technical standards.
b Make sure that your new boiler is instal-
led by a qualified heating engineer.
b The boiler must only be used for the pur-
pose for which it is designed and made.
The manufacturer declines all responsi-
bility, contractual or other, for damage
to property or injury to persons or ani-
mals caused by improper installation,
adjustment, maintenance or use.
b Do not tamper with the boiler's automa-
tic safety or control devices at any time
during its working life. The servicing of
such devices must be referred to the
manufacturer or supplier.
b The boiler is designed to generate hot
water and must be connected to a cen-
tral heating system and/or to a domestic
hot water distribution system compatible
with its performance and heat output.
b If water leaks from the boiler, turn off
the water supply and contact the manu-
facturer’s Technical Assistance Service
immediately.
b If the boiler is not going to be used for
an extended period of time, close the
gas shut-off cock and switch the boiler
off at the mains power switch. Empty the
boiler’s water circuit if there is any risk of
freezing.
b Periodically check that operating pressu-
re in the water circuit is over 1 bar.
b In the event of a fault or malfunction, shut
down the boiler and switch it off at the
mains. Do not attempt to repair or service
it yourself.
b The boiler must be serviced at least
once a year. You can save both time and

2 SAFETY PRECAUTIONS
Always observe the following fundamen-
tal safety precautions when operating your
Novella boiler.
b Do not use the boiler for any purpose for
which it was not designed.
b Do not touch the boiler when barefoot or
wet. Risk of electric shock!
b Do not operate any electrical switches,
telephones or any other equipment that
might cause a spark if you smell gas.
Thoroughly ventilate the room by ope-
ning wide all doors and windows, and
close the gas shut-off valve.
b Do not place objects on the boiler.
b Always switch the boiler off at the mains
switch before commencing any cleaning
operations.
b Do not store containers of flammable
substances in the room where the boiler
is installed.
b In the event of a fault or malfunction, do
not attempt to repair or service the boiler
yourself.
b Do not pull on or twist the boiler’s elec-
trical cables.
b Do not allow children or uninformed per-
sons to operate the boiler.
b Do not block the air vents in the room in
which the boiler is installed with rags or
paper etc.
b Do not obstruct or restrict the air vents
in the room where the boiler is installed.
To get the best from your boiler, always
remember the following hints.
- Periodic cleaning of the boiler’s casing with
soapy water not only keeps your boiler loo-
king attractive but also protects the casing
against rust and extends its working life.
- Installation of the optional accessories listed
on page 16 increases the level of comfort
in your home, ensures more rational use of
your boiler and helps save energy.

3 DESCRIPTION OF THE APPLIANCE
Novella boilers are floor standing, gas fuelled
boilers with an atmospheric burner and cast
iron heat exchanger. They are specially desig-
ned for use in central heating systems, but can
also generate domestic hot water if connected
to a suitable storage cylinder.
Novella boilers feature electronic ignition and
ionisation flame detection.
The control panel (fig. 3.1) houses all the con-
trols needed to control the various functions of
the boiler.

4 STARTING UP THE BOILER
Your new boiler must be started up for the first time by the manufacturer’s Technical Assistance
Service.
Subsequently, proceed as follows to start up the boiler whenever necessary.
Fig. 4.1
Fig. 4.2
Fig. 4.3
Once you have completed all the preparatory
steps, proceed as follows to start up the boiler
for the first time.
- Turn the boiler’s mains power switch ON
(fig. 4.1)
- 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) (fig. 4.2)
- Adjust the boiler’s temperature control to the
desired temperature (operation not neces-
sary if the boiler has been equipped with a
temperature controller) (fig. 4.3)
- Switch the boiler on at the control panel
switch and check that the green power indi-
cator lights (fig. 4.4).
The boiler will now start up and the burner will
remain lit until the set temperature is reached.
If any ignition or functioning errors occur, the
boiler enters “LOCK-OUT” and the red LED
on the control panel comes on to indicate this
(fig. 4.5).

5 SHUT-DOWN
If the boiler is not going to be used for an
extended period of time, perform the following
operations.
- Switch the boiler on at the control panel
switch and check that the green power indi-
cator lights (fig. 5.1).
- Turn the mains power switch OFF (fig. 5.2).
- Close the boiler’s fuel cock and water circuit
cock (fig. 5.3).
b Empty the boiler if there is any risk of
freezing
Fig. 5.1
Fig. 5.2
Fig. 5.3
Fig. 4.6
Fig. 4.7
Proceed as follows to reset the safety ther-
mostat.
- Wait for about 1 minute, then press the "bur-
ner reset" button (fig. 4.6).
- Wait for the burner to complete the entire
start-up cycle again, up to the ignition of
the flame.
The boiler will also shut down if the flue gas
thermostat trips. To reset the boiler in this
case, remove the hood and reset the flue gas
thermostat (fig. 4.7).
b If the flue gas thermostat trips repea-
tedly, make sure that the flue gas pipes
are not blocked and that the flue is pro-
perly constructed.
b Novella boilers are equipped with a fac-
tory-calibrated minimum pressure switch
for the gas supply. This shuts down the
boiler if the gas supply pressure is not
sufficient to ensure correct functioning.
Operation of this pressure switch is not
signalled.

6 MAINTENANCE
The only maintenance that the user can per-
form is the cleaning of the outside of the boiler
casing with a cloth damped in soapy water.
To remove stubborn marks, use a cloth dam-
ped in a 50% mix of water and denatured
alcohol or a suitable cleaning product.
Do not use abrasive cleaning pads or powder
detergents.
Never clean the boiler without first disconnec-
ting it from the mains electricity supply by tur-
ning the mains power switch and the control
panel switch OFF.
On request, the manufacturer’s Technical Assistance Service will also provide you with a system
service book. The Technical Assistance Service will also be pleased to instruct you how to get
the best from your new boiler.
Remember that safety legislation (in Italy,
Presidential Decree 412 of the 26th August
1993) obliges the person responsible for the
boiler to ensure that professionally qualified
personnel perform periodic maintenance.
The manufacturer’s Technical Assistance
Service is qualified to satisfy all legal require-
ments and can also offer scheduled mainte-
nance contracts.
Stipulation of a maintenance contract gua-
rantees:
- greater savings
- greater safety
- greater comfort and peace of mind.
