6 GAS PIPE
Important
The sizing of the pipes and any pressure reducers must be such as to guarantee the correct
operation of the appliances. The materials used must comply with the regulations in force in
the country where the system is installed.
WARNING
The gas piping must be made by qualied personnel with adequate skills and in compliance
with the national and local regulations in force on the subject and what is reported in this
booklet.
WARNING
Carry out the tightness test according to the regulations in force before putting the gas sup-
ply system into service.
6.1 CONNECTING THE APPLIANCE
a) The appliance cannot withstand pressures higher than 40 mbar (0.04 bar) otherwise the gas valve mem-
branes may break.
b) For natural gas: always install on the main line upstream, after the meter, a pressure stabilizer and a pres-
sure gauge with a scale of 0 ÷ 60 mbar (0.06 bar) and adjust the pressure to 20 mbar (0.02 bar); a higher
pressure can create bad combustion, diculty in igniting the ame.
c) For LPG gas (Butane-Propane): near the tank it is essential to install a “1st stage” pressure reducer in
order to reduce the pressure to 1.5 bar; on the main external line at the foot of the shed, always install a
“2nd stage” pressure reducer to reduce the pressure to the values indicated in paragraph 8.5 on page 92.
After the “2nd stage” reducer, install a pressure gauge scale 0 ÷ 60 mbar (0.06 bar) and adjust the pressure to
the values shown in tables 8.5 and 8.7 on pages 92 and 94; a higher pressure can create bad combustion,
diculty in igniting the ame.
d) Upstream and downstream of the main gas supply line, a manometer must always be installed in a visible
manner with a scale of 0 ÷ 60 mbar (0.06 bar) in order to check any dierence in pressure upstream and
downstream and therefore the reach of the entire network.
e) It is also possible, by closing the general gate valve and turning o all the appliances, to check the tight-
ness of the system and the gas valves, checking, after a short period, for any pressure drop on the pres-
sure gauges.
f) Always connect the appliances with a ball valve and anti-vibration exible gas joint.
g) Supply gas pressure adjustment: all appliances are tested and calibrated in the factory for the pressures
for which they are designed (see burner plate data or paragraph 8.5 on page 92).
WARNING
Seal the gas solenoid valve adjustment part after calibration.
