5.3 LPG CONVERSION
To change feeding from natural gas to LPG it is necessary to modify the unit using the
LPG conversion kit that is supplied as standard supplied with the unit. Follow the
instructions detailed in ”conversion to another type of gas” section and proceed as follows:
PRESSURE REGULATION TO THE BURNER FOR MODELS 41, 42 AND 51
To have:
the gas convector installed and connected to the electrical and gas
network.
1. Remove the cover.
2. Connect a pressure gauge in A (see Figure 18), after having removed the sealing
screw.
3. Turn on the unit (see paragraph “START UP (HEATING)” at page 15).
4. The maximum operating pressure only depend on the distribution network pressure
level which needs to be adequately regulated at 30 mbar (for G30 gas) or at 37
mbar (for G31 gas). The decreasing of the network pressure is possible by using
suitable first stage pressure regulators, close to the liquid gas tank, to reduce the
pressure to 1,5 bar and a second stage pressure regulator from 1,5 to 0,03 or 0,037
bar close to the unit (reducers have to be installed always outdoor). Therefore it is
necessary exclude the pressure regulator by closing completely the screw B of
Figure 18
.
In the case it could not be reached the adequate setting, operate on
the second stage regulator.
5. Turn off the unit, disconnect the pressure gauge and re- fix the seal screw.
After the setting operation it is obligatory to seal the screws of gas regulation.
