4.2. VENTILATION
• Proper ventilation is highly essential for optimum perfor-
mance. A strong exhaust will create a vacuum in the room.
For an exhaust vent to work properly, replacement air must
enter the room.
The amount of air that enters must equal the amount
exhausted.
• All gas burners and pilots need sufficient air to operate.
Large objects should not be placed in front of the appliance(s)
wich would obstruct the flow of air into the front.
• The National Fire Protection Association, Inc states in its
NFPA latestedition that local codes are the "authority
having jurisdiction" when it comes to installation
requirements for equipment. Therefore, installations
should comply with all local codes.

5.1. GAS APPLIANCES
IMPORTANT! This appliance is designed and approved to
operate with G20 gas 20mbar; to convert it to another type
of gas, follow the instructions in paragraph 5.1.6. of this
chapter.
5.1.1. BEFORE CONNECTION
• Fit a rapid gas shut-off cock ahead of each appliance.
Install the cock/valve in an easily accessed place.
• Clean the supply pipes in order to remove any dust, dirt
or foreign matter that could block the supply.
• Do not use supply pipes of a diameter smaller than that
for which the appliance is designed.
• Fit a rapid gas shut-off cock ahead of each appliance in
an easily accessed place.
• After installation, use soapy water to check connections
for leaks.
• Make sure that the appliance is arranged for the type of
gas to be used. Otherwise, carefully follow the
instructions given in paragraph: "Conversion to a
different type of gas".
• In addition to installation, any maintenance operation
(gas, electricity) must only be carried out by the utility
company or an authorized installation technician.
5.1.2. CONNECTION
• The appliance is arranged for connection on the bottom
right hand side (Fig. 4A - point C).
• Before connecting the appliance to the gas supply,
remove the protective plastic cover from the appliance
gas connection.
• The appliance is provided with a second gas connection
on the rear right hand side. To use this connection,
unscrew the metal plug, screw it onto the lower inlet and
connect to the mains gas.
5.1.3. SUPPLY PRESSURE CHECK
Make sure the appliance is suitable for the type of gas
available, according to that given on the dataplate
(otherwise, follow the instructions given in par. "Conversion
to a different type of gas"). The supply pressure must be
measured with the appliance operating, using a manometer
(min. 0.1 mbar).
• Remove the control panel.
• Remove retaining screw "N" from the pressure point and
connect the manometer "O" (fig. 2A).
• Compare the value read on the manometer with that
given in table.
mbar
Natural gas
"w.c.
mbar
Propane
"w.c.
• If the manometer gives a pressure outside the range of
values in table A, do not start the appliance, and consult
the gas company.
5.1.4 GAS PRESSURE REGULATOR
• The section of the gas supply line must be sufficient to
ensure the gas flow necessary for full operation of all
the appliances connected to the mains.
• The pressure regulator and the rapid-action gas shut-off
valve are both supplied with the appliance in a plastic
pouch; they must be installed before the appliance. The
rapid-action gas shut-off valve is to be installed in an
easily accessible position.
• Figure 6 shows how to assemble the valve and the
regulator:
- "A"
side link gas toward the appliance;
- "B"
pressure regulator (3.3"x2.9"x2.7" /
85x75x71mm);
- "C"
rapid-action gas shut-off valve;
- "D"
side link gas from the feeding gas line.
Use the same diameter joining the feeding gas line and
the valve "C."
