INSTALLATION

The installation must conform to the require-
ENG
ments of the Authority having jurisdiction or, in
the absence of such requirement, to the Natio-
FR
nal Fuel Gas Code, ANSI Z223. 1 /NFPA 54 or
CAN/CSA B149. 1 natural gas and propane
Installation Code. Where required by the
Authority having jurisdiction, the installation
must conform to the Standard for Controls
and Safety Devices for Automatically Fired Boi-
lers, ANSI/ASME CSD-1.
All boilers must be installed with a proper pres-
sure relief valve. Pressure relief valves must be
installed to conform to ANSI/ASME Boiler and
PressureVessel 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
lo 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 familiar with the
requirements that are contained in this
manual. The boiler must not be installed on car-
peting. The boiler when used in connection 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
onnected to heating coils located in air hand-
ling units where they may be exposed to refri-
gerated air circulation must be equipped with
flow control valves or other automatic means
to prevent gravity circulation of he boiler water
during the cooling cycle. Service instructions
and recommended frequency guidelines perio-
dic examination of venting systems every 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 retai-
ning screw andremove the cover.When the
pump is running and water is flowing around
the boiler , the actuator lifts off the micro swit-
ch. Check that the operation of the actuator ;
Ensure that it is free and that it lif ts and
returns. If necessary lubricate the pivot point of
the actuator. Flue gas passageways should be
checked and cleaned every six months.
Condensate collection and disposal system
should be checked and re-sealed every six
months.The burner should be checked and
cleaned every six months. Inspect the burner
and if necessary clean using a soft brush and a
vacuum cleaner, taking care not to damage the
front insulation.
Check the ignition /ionisation electrode, check
the ignition spark gap (4 mm +/- 0.5 mm)
(0. 1 6 in. +/- 0.02 in.). Check the ionisation elec-
trode, check the distance from the burner
(18.7 mm +/- 1 mm) (0.74 in. +/- 0.04 in).
Before reassembly inspect all seals and repla-
ce as required.
Furthermore, the installation must be in accor-
dance with current standards and regulations.

2. 1 VENTILATION OF BOILER ROOM

When using air from the boiler room, an ade-
8
quate air supply shall by provided for combu-
stion of this boiler.
An insufficient supply can result in poor com-
bustion and possible sooting of the burnr,
combustion chamber or flue passageway.
The boilers installed using inside air supply mus
provide provisions for Combustion Air and Ven-
tilation Air in accordance with section 5.3,
Air for Combustion and Ventilation, of the
National Fuel Gas Code, ANSI Z 223, 1 /NFPA
54, or section 7,2, 7.3, or 7.4, of CAN/CSA B
149,
Installation Codes, or local codes having juri-
sdiction. 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 operating 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 con-
sumed by the varius appliances. Consequently,
it is necessary to make openings in the walls
for the air inlet into the rooms.
These openings must meet the following requi-
rements:
1. Have a total free section of a least 25
mm2 every kW (1 in2 for every 1000
Btu/hr) of heat input, with a minimum of
100 cm2 (15.5 in2);
2. Where required 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 mate-
rials, gasoline and other flammable vapors and
liquids.

2.2 CONNECTING UP SYSTEM

To protect the heat system from damaging
corrosion, flakes or deposits, before installation
it is extremely important to clean the system
using suitable products such as, descaler or
slug removing solution. For long-term protec-
tion against corrosion and deposits, the use of
inhibitors is recommended after cleaning the
R C.H. return
M C.H. supply
G Gas connection
E D.H.W. inlet
U D.H.W. outlet
system. It is important to check the concentra-
tion of the inhibitor after each system modifica-
tion and during maintenance following the
manufacturer'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 deli-
very/return pipes.
WARNING: Failure to clean the heat system
or add an adequate inhibitor invalidates the
device's warranty.
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.

2.2.3

Gas Requirements

Read the data plate to be sure the boiler is
made for the type of gas being used.
An adhesive data plate is 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
boiler. Call your dealer.
The gas piping must be installed according to
all local and state codes, or in absence of
local and state codes, with the latest "Natural
gas and propane installation code",
CAN/CSA-B 149. 1 or "National Fuel Gas
Code", ANSI Z223. 1 (NFPA 54).
Consult the "Natural gas and propane installa-
tion code" or "National Fuel Gas Code" for the
recommended gas pipe size of other mate-
rials.
