• If connecting with a hose, follow the instructions below:
Use a hose that complies with the current regulations
-
(it is important to periodically replace it as indicated
on the hose's stamp).
The hose must not be any longer than 1 metre.
-
Attach the hose to the connector (1) and if necessary,
-
install the conical connector (8) and its seal (7).
The hose must not be placed near potential heat
-
sources and in any case, must not reach a temperature
higher than 50°C.
The hose must not be subjected to traction or twisting
-
stress, and must not have any kinks. It must be possible
to inspect the hose along its entire length, and it must
not come into contact with sharp edges or corners.
If the hose needs to be connected to the ma-
chine, we supply a conical fitting (8) with seal
(7) to be installed on the cylindrical fitting (1).

• When connecting with a rigid pipe: connect the Ø8 copper
pipe to the 1/4 gas fitting (1).
• Check that the type of gas used corresponds to the one in-
dicated on the machine's gas dataplate. If a different gas
is used, replace the injector (2) as shown in the Gas Table
in para. "5.8.3 Gas table" on page 33 and replace the
"Gas preparation" label on the heating unit cover with one
corresponding to the gas being used (supplied with the
injector). Ensure that there is a correct supply pressure by
connecting a pressure gauge to the fitting (3) and check
that the injector inlet has the correct minimum pressure
by connecting a pressure gauge to the fitting (6).
• Check that the amount of air intake (X) corresponds to the
amount indicated in the Gas Table; see para. "5.8.3 Gas
table" on page 33.
• To carry out any adjustments, proceed as follows:
- Loosen the screw (4).
Move the extraction guard (5) to the required height.
-
Tighten the screw (4).
-
If, when starting the burner, the colour of the flame is
-
not blue, slightly modify the air intake height until the
correct colour is obtained.
• As soon as it has been connected, check for any gas leaks
by wiping all the connections with a soapy solution.
