Otherwise, carefully follow the instructions given in the para-
graph H.3
Conversion to another type of gas
1. Remove the plastic protector from the appliance gas
connection before connecting to the gas pipe.
2. Fit a rapid gas shut-off valve ahead of each appliance.
3. Install the tap/valve in an easily accessed place.
4. Clean the pipes to remove any dust, dirt or foreign matter
which could block the supply.

Gas connection
H.6.1
Connecting to the gas supply
The appliance requires a 1″ gas pipe with shut-off valve on-
site; the appliance's gas supply is 1/2″. See the nozzle table
(spare parts catalogue / service manual) for the relevant gas
volumes.
Connect the gas supply in accordance with the paragraph F.2
Installation and connection diagram
.
To get access to the gas pipes, follow the instructions in
paragraph F.3
Accessing the appliance’s internal components

H.6.3
Sealing
The screws on the gas lines must be sealed with suitable
sealing material. Recommended sealing material for gas-
supplying parts:
• Loctite 577 for all connections except nozzles;
• Loctite 511 for nozzles;
We recommend to install a dirt trap filter in the gas pipe.
After connection, all lines carrying gas must be tested for leaks
at operating pressure by painting with non-corrosive foam-
forming media.
Before first use, bleed the gas pipe using the pressure gauge
nipple in the main gas pipe.
H.6.4
Check the gas supply pressure
Make sure the appliance is suitable for the type of gas
available, according to that given on the data plate (otherwise,
follow the instructions given in the paragraph H.3
The supply pressure must be measured while the appliance
operates, using a manometer (min. 0,1 mbar).
1. Turn off the main gas and upstream stop tap at the
location;
2. To connect pressure gauge remove screw from test
connector
A
; now connect the pressure gauge by attach-
ing the flexible hose (see previous image);
3. Open the shut off valve completely and switch on the
appliance;
4. Check whether the specified permissible connection pres-
sure range applies;
5. After taking the reading, tighten the seal screw
A
on the
nipple and test it for leakage;
H.6.5
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 system.
If the gas pressure is higher than that specified or is difficult to
regulate (not stable), install a gas pressure regulator in an
easily accessed position ahead of the appliance.
The pressure regulator should preferably be fitted horizontally,
to ensure the right outlet pressure.
