Code", ANSI Z223. 1 (NFPA 54). Consult the
ENG
"Natural gas and propane installation code" or
"National Flue Gas Code" for the recommen-
FR
ded gas pipe size of other materials. The sec-
tions of the piping making up the system must
be such as to guarantee a supply of gas suffi-
cient 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 pressures
under 17 mbar (7"W.C.);
2. 2.5 mbar (1.0"W.C.) for supply pressures
fr om 17 mbar (7"W.C.) t o 35 mbar
(14"W.C.).
Gas connestions must be made in accordance
with current standards and regulations. When
dimensioning gas pipes from the meter to the
boiler, both capacity volume (consumption) in
m /hr (ft /hr) and gas density must be taken
3 3
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 isola-
ted from the gas supply piping system by clo-
sing 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 placing 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 shutoff
device must be tested.
To testing the system:
- Close the gas valve (gas cock)
- feed to boiler
- initiate a call for heat (see user instructions)
- verify red led "Ignition lock-out" light is on,
after ignition boiler.
- reset boiler by rotating the function knob to
chimney sweep and st ay at least one
second, and after back to "winter" or "sum-
mer" position.
- finally open the gas cock.
2.3.2 Filter on the gas pipe
The gas valve is supplied by the factory with an
inlet filter, which, however, is not adequate to
entrap all the impurities in the gas or in gas
main pipes.
To prevent malfunctioning of the valve, or in cer-
tain cases even to cut out the safety device
with which the valve is equipped, install an ade-
quate filter on the gas pipe. In any case, a sedi-
ment trap must be installed upstream of the
gas controls.

IMPORTANT:
– Each additional 90° cur ve (code
8095801) installed reduces the avai-
lable length by 0.90 metres (3 ft).
– Each additional 45° curve installed
reduces the available length by 0.45
metres (1.5 ft).
– It is advisable to assemble the con-
densation collector (8) on vertical seg-
ments exceeding 2.5 metres (8.2 ft)
in length and to limit maximum length
to 4 metres (13. 1 ft).
