INSTALLATION
The installation must conform to the require-
ments of the Authority having jurisdiction or, in
the absence of such requirement, to the Natio-
nal Fuel Gas Code, ANSI Z223. 1 /NFPA 54
and, or CAN/CGAB149 Installation Code.
Where required by the Authority having juri-
sdiction, the installation must conform to the
Standard for Controls and Safety Devices for
Automatically Fired Boilers, ANSI/ASME CSD-
1. All boilers must be installed with a proper
pressure relief valve. Pressure relief valves
must be installed to confirm to ANSI/ASME
Boiler and Pressure Vessel Code, Section IV, or
CSA B51, as applicable. If the boiler is installed
above the radiation level, or as required by the
Authority having jurisdiction, the installer must
provide a low water cut-off device at a time of
installation. The boiler must be installed in a
fixed location and only by a qualified installer,
service agency or the gas supplier and is fami-
liar with the requirement that are contained in
this manual. Furthermore, the installation
must be in accordance with current standars
and regulations. The boiler must not be instal-
led on carpeting. The boiler when used in con-
nection with a refrigeration system, must be
installed so the chilled medium is piped in
parallel with the boiler with appropriate valves
to prevent the chilled medium from entering
the boiler. The boiler piping system of a hot
water boiler connected to heating coils located
in air handling units where they may be expo-
sed to refrigerated air circulation must be
equipped with flow control valves or other
automatic means to prevent gravity circulation
of the boiler water during the cooling cycle.
Service instructions and recommended fre-
quency guidelines periodic examination of ven-
ting syst ems ever y six months. Venting
systems, the vent-air intake system, screens
in the vent terminal should be checked and
cleaned every six months. Low water cutoff
should be checked and cleaned every six
months. Remove small cover retaining screw
and remove the cover. When the pump is run-
ning and water is flowing around the boiler ,
the actuator lifts off the micro switch. Check
that the operation of the actuator ; Ensure
that it is free and that it lifts and returns. If
necessary lubricate the pivot point of the
actuator. Flue gas passageways should be
checked and cleaned every six months. The
burner should be checked and cleaned every
six months. Inspect the burner and if neces-
sary clean using a soft brush and a vacuum
cleaner, taking care not to damage the front
insulation. Check the ignition /ionisation elec-
trode, check the ignition spark gap (3.5 mm
+/- 0.5 mm) (0. 1 38 in. +/- 0.02 in.). Before
reassembly inspect all seals and replace as
required. Furthermore, the installation must
be in accordance with current standards and
regulations.
2. 1
VENTILATION OF BOILER ROOM
When using air from the boiler room, an ade-
quate air supply shall by provided for combu-
stion of this boiler. An insufficient supply can
result in poor combustion and possible soo-
ting of the burner, combustion chamber or
flue passageway. The boilers installed using
inside air supply must provide provisions for
Combustion Air and Ventilation Air in accor-
dance with section 53, Air for Combustion and
Ventilation, of the National Flue Gas Code,
ANSI Z 223, 1 /NFPA 54, or section 7,2, 7.3, or
7.4, of CAN/CGA B 149, Installation Codes, or
local codes having jurisdiction. Where an
exhaust fan or any other air consuming
appliance is installed in the same space as the
boiler, sufficient air openings must be available
to provide fresh air when all appliance are ope-
rating simultaneously. It is essential that in
rooms where the boiler are installed at least
as much air can arrive as required by normal
combustion of the gas consumed by the
various appliances. Consequently, it is neces-
sary to make openings in the walls for the air
inlet into the rooms. These openings must
meet the following requirements:
1.
Have a total free section of a least
2225 mm
2
every kW (1 in
1000 Btu/hr) of heat input, with a mini-
mum of 100 cm
2
(15.5 in
2
);
2. They must by located not more than 18
in or less than 6 in above the floor level,
not prone to obstruction and protected
by a grid which does not reduce the
effective section required for the passa-
ge of air;
3. Where requide by jursdiction or when
required for additional opening must be
provided at the highest elevation practi-
cal.
With a hermetically sealed combustion cham-
ber and air supply circuit from outdoors, may
be installed in any room in the home. Keep boi-
ler area clear and free from combustible
materials, gasoline and other flammable
vapors and liquids.
2.2
INSTALLATION PLATE
The installation plate code 6246958 is sup-
plied with the boiler.
The optional installation plate code 8075416
is supplied with an instruction sheet for the
fixing.
2.2. 1
Isolating valves kit
To fit the isolating valves, supplied with the boi-
ler, use figure 4 for assembly.
2.2.2
System connection unions
The follow is available to facilitate water and
gas connection of the boiler with the heating
system: for assembly of the unions to see fig. 1.
2.3
CONNECTING UP SYSTEM
To protect the heat system from damaging
corrosion, flakes or deposits, before installa-
tion it is extremely important to clean the
system using suitable products such as,
descaler or slug removing solution. For long-
term protection against corrosion and depo-
sits, the use of inhibitors is required for new
installations and after cleaning the system. It
is important to check the concentration of the
2
for every
inhibitor after each system modification and
during maintenance following the manufactu-
rer's instructions (specific tests are available
at your dealer). The safety valve drain must be
connected to a collection funnel to collect any
discharge during interventions. If the heating
system is on a higher floor than the boiler,
install the on/off taps supplied in kit on the
heating system delivery/return pipes.
WARNING: Failure to clean the heat system
or add an adequate inhibitor invalidates the
device's warranty.
2.3. 1
Gas Requirements
Read the date plate to be sure the water hea-
ter is made for the type of gas being used. An
adhesive data plate is stuck inside the front
panel, it contains all the technical data iden-
tifying the boiler and the type of gas for which
the boiler is arranged. If the information does
not agree with the type of gas available, do not
install or operate the water heater. Call your
dealer. The gas piping must be installed accor-
ding to all local and state codes, or in absence
of local and state codes, with the latest "Natu-
ral gas and pr opane ins t allation code",
CAN/CSA-B 149. 1 or "National Flue Gas
