
That the gas supply system is
provided with all the safety devices
and controls required under current
national and local codes.


12.3 - Confi rming
the boiler’s gas
type
The type of gas and the gas supply
pressure that the boiler is set up for is
listed on the rating label.
The boiler can operate using one of
the following two gases:
NATURAL GAS
Maximum supply pressure = 13
in.W.C. (
33.0 mbar).
Minimum supply pressure = 3 in.W.C.
(
7.6 mbar) .
LP Gas
Maximum supply pressure = 13
in.W.C.
(33.0 mbar) .
Minimum supply pressure = 3 in.W.C.
(7.6 mbar) .
12.4 - Gas type
conversion
If the gas available at the installation
site is not the type the boiler is
confi gured to use, the boiler must be
converted. Special conversion kits are
available for this purpose inside the
boiler. Follow instruction on Section
11.6.
WARNING!!!
Conversion
of the boiler to use another
type of gas must be carried
out by a qualifi ed technician.
Improper conversion of the
boiler could result in a fi re or
an explosion causing severe
personal injury or death!
12.5 - Start-up of
the boiler
1. Open the manual gas shut off valve
(Figure 11-1),.
2. Switch the on/off power switch, item
“12” in Figure 13-1, to “on”.
3. Upon start-up, an is shown for
3 minutes while the boiler goes
through its heating system purge
cycle. To by-pass this stage, press
the and keys together
until a blinking appears.
Then press the button.
4. Rotate knobs “7” and “11” shown
in Figure 13-1 to the desired
temperature.
5. The boiler will fi re only when
the room thermostat calls for
heat. If an external temperature
sensor is connected, check that
the temperature calculated is
higher than the minimum running
temperature as explained in
Section 13.10.
6. If the pump indicator is illuminated,
item “6” in Figure 13-1, but the
pump is not running, it may be
stuck. If this is the case, shut-off the
boiler and release the pump.
7. If the pump indicator is illuminated
but the heating system does not
heat up, repeat the air purging
operations on both the boiler and
the heating system.
12.6 - Ignition
control testing
After placing the boiler in operation,
the ignition control’s safety shutoff
function must be tested as follow:
1. turn the power switch (item “12” in
Figure 13-1) to on;
2. close the room thermostat to create
a call for heat;
3. turn knobs “7” and “11” in Figure
13-1 to their maximum position;
4. wait a few minutes for the burner
to light-up as indicated when light
“3” shown in Figure 13-1 stays
illuminated.
5. close the manual gas shutoff valve,
see Figure 11-1;
6. after 2 minutes, the display must
show L01;
7. open the manual gas shutoff valve,
see Figure 11-1;
8. verify your gas meter, gas fl ow
must be zero.
WARNING!!!
If gas fl ow
occurs, close the manual gas
shutoff valve and troubleshoot
the system to determine why
there is gas fl ow when the gas
valve should be deenergized.
Do not operate the boiler until
the problem is resolved or
a fi re or explosion causing
property damage, personal
injury or loss of life may occur!
