long-term protection against corrosion and
deposits, the use of inhibitors is recom-
mended after cleaning the system. It is
important to check the concentration 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 collec-
tion 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 inva-
lidates the device's warranty.
2.3. 1 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 informa-
tion does not agree with the type of gas
available, do not install or operate the boi-
ler. 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 pro-
pane installation code", CAN/CSA-B 149. 1
or "National Fuel Gas Code", ANSI Z223. 1
(NFPA 54). Consult the "Natural gas and
propane installation code" or "National Fuel
Gas Code" for the recommended gas pipe
size of other materials. The sections of the
piping making up the system must be such
as to guarantee a supply of gas sufficient
to cover the maximum demand, limiting
pressure loss between the gas meter and
any apparatus being used to not greater
than:
1. 1.2 mbar (0.5"W.C.) for supply pressu-
res under 17 mbar (7"W.C.);
2. 2.5 mbar (1.0"W.C.) for supply pressu-
res from 17 mbar (7"W.C.) to 35 mbar
(14"W.C.).
Gas connections must be made in accor-
dance with current standards and regula-
tions. When a vertical section of piping is
installed up stream/side of the boiler, must
be installed a sediment trap at the inlet
that a sediment trap must be provided
ups tr eam of the gas contr ols. When
dimensioning gas pipes from the meter to
the boiler, both capacity volume (consump-
tion) in m 3 /hr (ft 3 /hr) and gas density
must be taken into account. The boiler and
the boilers gas connection must be leak
tested before it is put in to operation. The
boiler and its individual shut-off valve must
be disconnected from the gas supply piping
system during pressure testing of the
system at pressures in excess of 1/2 psi
(3.5 kPa). The boiler must be isolated from
the gas supply piping system by closing its
individual manual shut off valve during any
pressure testing of the supply piping
system at test pressures equal to or less
than 1/2 psi (3.5 kPa). The boiler shall be
installed such that the gas ignition system
components are protected from water
(dripping, spraying, rain etc.) during boiler
operation or service (circulators or control
replacement etc.). The boiler and its gas
connection must be leak tested before pla-
cing the the boiler is put into operation. Use
a chloride-free soap and water solution
(bubbles forming indicate a leak) or other
approved method. After placing the boiler
in operation, the ignition system safety shu-
toff device must be tested.
To testing the system :
- close the gas valve (gas cock)
- to feed the boiler
- to verify the ignition of the led "Ignition
lock"
- to open the gas cock and to unblock
"Reset".
2.3.2 Condensation drain installation
A siphoned drain must be connected to the
civil drain by a pipe with minimum 6 mm
(1/4 in) for every 300 mm (1 foot) gra-
dient for condensation collection.
Only normal plastic civil drain pipes are
suitable to convey condensation to the
building's sewer drain.
2.3.3 Gas pipe filter
The gas valve has a standard input filter
which, in any case, is not capable of filtering
all the impurities contained in the gas and
mains piping. To prevent poor valve opera-
tions or in certain cases, excluding the val-
ve's safety features, we recommend instal-
ling a suitable filter on the gas pipe.
2.5

SYSTEM FILLING

Filling of the boiler and the system is done
by installing a pressure reducing valve. The
charge pressure, with the system cold,
must be between 1 and 1.2 bar (14.5 and
17.4 psi).
Filling must be done slowly so as to allow
any air bubbles to be bled off through the
air valves. Should the pressure have risen
well above the limit expected, discharge the
over pressure by opening the pressure-
relief valve. Bleed pump by loosen plug at
back of motor.
Once air is removed re-tighten plug. It may
be necessary to free the pump motor befo-
re filling the system.
This is done by removing the pump plug
and turning the pump shaft loose.
Do not forget to re-tighten pump plug befo-
re filling system. Residual head and head
losses can be determined using figure 14
of this manual.

Dewy 60 BFR using a hydraulic compensa-

2.6

FLUES/CHIMNEYS

The flue or chimney used to release the
products of combustion into the atmosphe-
re must comply with current standards
and regulations (fig. 3/a). Horizontal vent
lengths must be supported every 1 meter
(40 in) or less to prevent sagging.
The boiler can be exhausted using separa-
te pipe or forced draft. Follow the appro-
priate instructions below for your particu-
lar venting configuration.
2.6. 1 Installation
separate pipes (fig. 4)
The vent pipe must be certified ø 3" (76
mm) category IV venting; for this type of
flues it is necessary to demand kit optional
code 8089925 for tubes 3" in steel
(AL294C), and the kit code 8089926 for
tubes 3" in PVC or CPVC (standard with
units). When installing the pipes, follow clo-
sely the requirements of the current stan-
dards and regulations, as well as the fol-
lowing practical pointers:
1. With direct intake from outside, when
the pipe is longer than 1 m (3.28 ft - 40
in), you are recommended to insulate
the piping so as to prevent formation of
dew on the outside of the piping during
particularly hard periods of the year.
2. With the outlet pipe outside the building
or in cold indoor environments, insula-
tion is necessary to prevent burner fai-
lure during trial for ignition. In such
cases, provide for a condensate-collec-
tor system on the piping.
3. If a segment of the flue passes through
a flammable wall, this segment must be
insulated with a glass wool pipe insula-
tor 30 mm (1 in.) thick, with a density of
50 kg/m (3lb/f t ) or follow vent
3 3
manufacturers instructions for clearan-
ces to combustibles.
4. The distance between the intake air and
the vent pipe must be within 300 mm
(1 ft - 12 in.).
5. Slope the venting towards the wall hung
boiler, for long runs or installation
where condensation in vent may cause
flame failure during trial for ignition pro-
vide a condensation collection on the
piping, close to the wall hung boiler.
The maximum overall length of the intake
and exhaust ducts depends on the head
losses of the single fittings installed and
must not be greater than 13 mm H
(0.51 "W.C.).
For head losses in the fittings, refer to Table 1.
