relevant section of this booklet, in
order to ensure that it works efficiently and correctly.
Where the equipment is not to be
used for an extensive period of time,
disconnect it from the electrical
power supply and shut the fuel stopcock.
Where there is a danger of freezing,
add antifreeze. Draining the system
is not recommended as this may
damage the overall system. For this
purpose use non-freeze products
specifically made for multi-metal heating equipment.
IMPORTANT
For equipment powered by gas fuel, if
the smell of gas is sensed in the area,
proceed as follows:
- Do not activate any electrical
switches or start any electrical
equipment.
- Do not light any flames and do
not smoke.
- Shut the central gas stopcock.

To determine combustion performance the following measurements
must be taken:
• The temperature of the combustion-supporting air.
• The temperature of the smoke and
the percentage of CO
2 in samples
drawn from the hole provided for this
purpose in the smoke duct.
Taking the specific measurements with the boiler running at
normal load.
3.2.7 Connecting to the gas mains
The gas supply pipe is to have a
cross-section that is equal to or
greater than that on the burner.
Installation standards must be complied with and are taken as being an
integral part of this booklet.
Remember that before putting an
internal gas distribution system
into service, before it is connected to the meter, it must be checked for leaks.
If any part of the system is inaccessible the leak test must be carried out before the pipes are
covered up.
The leak test must not be carried
out using combustible gas. Use
air or nitrogen for this purpose.
Once there is gas in the pipes,
checking for leaks using a naked
flame is forbidden.
Use the products made for this
purpose that are available on the
market.
3.2.8 Connecting to the electricity
power supply
ALTAIR boilers have a terminal board
for connecting up a three-pole power
supply cable, and a suitable cable
clamp to prevent it being torn out.
This boiler must be connected to a
230V-50Hz electrical power supply.
When forming the connection
respect the phase/neutral polarity.
Installation standards must be complied with and are taken as being an
integral part of this booklet.
A two-pole switch must be fitted
upstream of the boiler to allow all
maintenance work to be carried out
in complete safety.
The power supply to the boiler must
be fitted with a differential magneticthermal trip-switch of a suitable tripping power.
The electrical power supply must be
safely earthed.
This basic safety requirement must
be checked. In case of doubt, call in
professionally qualified personnel to
check the electrical system carefully.
NOVA FLORIDA accepts no
responsibility whatsoever for any
damage caused due to failure to
earth the system. Piping for gas,
plumbing, or heating systems are
not suitable for earthing this
system.
3.2.9 Plumbing Connections
Before installation the system
should be cleaned in order to remove the impurities that may come
from the components as far as possible, as these could damage the circulation or heat exchange units.
The heating feed and return pipes
must be connected up to the respective couplings on the boiler.
When sizing the piping for the heating system, bear in mind the load
losses caused by radiators, thermostatic valves, radiator gate valves,
and the configuration of the system
itself.
3.2.10 Installation of original kits
NOVA FLORIDA provides original
kits for installing clock programmers,
cards for managing a remote boiler,
and for installing a heat-regulating
unit.
These original kits are to be installed
in compliance with the instructions
supplied with them.
3.3 Filling the system
Once all the connections in the
system have been completed, the
heating circuit can be filled.
This must be carried out carefully,
and in the following steps:
• Open the bleeding valves on the
radiators and make sure that the
vent valve installed in the boiler
room is working.
• Gradually open the relevant stopcock to fill the system and make
sure that all automatic air vents
installed in the system are working
properly.
• Close the vent valve as soon as
water comes out of it.
• Use the pressure gauge installed
in the boiler room to check when the
pressure reaches 0,8 / 1 bar.
• Shut the filling stopcock and bleed
any air out again using the bleeding
11
•Having started the boiler and
brought the system up to its working
temperature, stop the pump and
repeat the air bleeding operations.
• Allow the system to cool and return
the water pressure to 0,8 / 1 bar.
WARNING
The UNI CTI 8065/89 standard –
Treatment of water in domestic heating systems – determines and defines the chemical and chemicalphysical characteristics of the water
used in domestic heating systems,
and especially, “… in order to optimise performance and safety, to preserve these conditions over time, to
ensure long-lasting regular operation
of auxiliary equipment as well, and to
minimise energy consumption, thereby integrating current laws and
standards …”.
In this regard specific products must
be used that are suitable for multimetal plants.
Note: The boiler is fitted with a
drain stopcock at the front of the
unit that can be used to empty the
system.
3.4 Starting the Boiler
3.4.1 Preliminary Checks
Before starting the boiler it is best to
check that:
• The smoke flue has been installed
in compliance with instructions.
When the boiler is running no products generated by combustion
are to leak from any gaskets.
• The boiler power supply is 230 V –
50 Hz.
• The system is properly filled with
water (pressure on the water gauge
0,8 / 1 bar).
• All stopcocks in the system’s
piping are open.
• The fuel supply stopcock is open.
• There are no gas leaks.
• The external main switch is on.
• The boiler’s safety valve is not
blocked.
• There are no water leaks.
To speed up and facilitate igniting the
boiler for the first time, bleed the air
out of the gas piping using the gas
pressure valve socket.
Close the pressure socket carefully
after bleeding the system.
3.4.2 Starting Up and Switching Off
For starting up and switching off the
boiler, follow the “User’s Instructions”.
12
The plant pump must be
connected directly to the
boiler terminal board
(terminals 11 and 12).

3.6 Gas Transformation
Changing a boiler over from natural
gas to LPG and vice versa is only to
be carried out by qualified personnel.
To check the setting values for the
nozzles and gas supply pressure, use
a pressure gauge connected to the
pressure sockets on the valves.
3.6.1 Change over from natural gas
to LPG
Proceed as follows:
• Remove the natural gas nozzle from
the pilot burner after having unscrewed
the nut that holds the olive and vent the
gas supply pipe to the pilot burner.
• Position the LPG nozzle checking
that it is as indicated in the technical
data table, and after repositioning the
gas supply pipe tighten the nut that
secures the olive.
• Remove the natural gas nozzle on
the main burner and fit the LPG nozz-
le, checking that this is as indicated in
the technical data table.
• Unscrew the pressure regulating cap
on the gas valve and tighten the pressure regulating screw all the way.
• Screw the pressure regulating cap
back on and seal it (using paint or a
self-adhesive label, for example).
• Check the gas circuit for leaks, especially the points that were disconnected.
• Affix the self-adhesive label provided
that indicates the type of gas and pressure for which the equipment is set.
3.6.2 Change over from LPG to
natural gas
Proceed as follows:
• Remove the LPG nozzle from the
pilot burner after having unscrewed the
nut that holds the olive and vent the
gas supply pipe to the pilot burner.
• Position the natural gas nozzle checking that it is as indicated in the technical data table, and after repositioning
the gas supply pipe tighten the nut that
secures the olive.
• Remove the LPG nozzle on the main
burner and fit the natural gas nozzle,
checking that this is as indicated in the
technical data table.
• Unscrew the pressure regulating cap
on the gas valve and unscrew the
pressure regulating screws so that the
pressure at the outlet is as specified in
the technical data table.
• Screw the pressure regulating cap
back on and seal it (using paint or a
self-adhesive label, for example).
• Check the gas circuit for leaks,
especially the points that were disconnected.
• Affix the self-adhesive label provided
that indicates the type of gas and pressure for which the equipment is set.
4. MAINTENANCE
In order to ensure that the equipment is efficient and that it functions
correctly, maintenance must be carried out annually, based on the programme laid out below:
It is obligatory for all maintenance
(and repair) operations to be carried out by qualified personnel.
Before starting any maintenance
work that involves replacing components and/or cleaning the inside of the boiler, disconnect the
equipment from the electrical
power supply.
Maintenance programme
Routine maintenance must include
the following checks:
- Check of the general integrity of
the boiler.
- Checking the gas supply to the
boiler for leaks.
- Checking ignition of the boiler.
- Checking the boiler’s combustion
parameters by analysing the smoke
(this check is done every two years
if the boiler is installed on its own.
Where the boiler is installed in a
cascading system, this check is run
annually).
- Checking the integrity, good state
of preservation, and leak test on the
smoke flue.
- Checking the integrity of safety
devices on the boiler in general.
- Checking for water leaks and
rusting on the boiler’s couplings.
- Checking the efficiency of the
system’s safety valve.
The following cleaning is to be
done (with the boiler cold):
- General internal cleanliness of the
boiler.
- Cleanliness of the burner and
resetting of the same as necessary.
- Cleanliness of the smoke side of
the heat exchanger. This can be
done using swabs and vacuum cleaners to remove soot deposits on the
sides and fins used for exchanging
heat.
Alternatively specific chemical products can be used in compliance
with the instructions for use of the
same.
Do not use inflammable products
such as petrol, solvents or any
other such material to clean the
heat exchanger.
When working on the boiler for
the first time, check.
The declaration of conformity for the
plant.
- The plant handbook.
Also check:
- The suitability of the boiler room.
- The ventilation openings in the
room.
- The smoke evacuation flues, and
the diameters and lengths of these.
- That the boiler has been correctly
installed as per the instructions in
this booklet.
If the equipment is not able to
work correctly, or where it poses
any danger to people, animals or
property, inform the person
responsible for the plant and
draw up a statement in this
regard.
