10.1 Gas connection regulations
NOTE
Exceeding the connection flow pressure
A connection flow pressure above 65 mbar [0.94 psi] leads to a malfunction
of the device and damage of gas components.
n
For natural gas, maintain the maximum connection flow pressure of 30
mbar [0.44 psi].
n
For liquid gas, maintain the maximum connection flow pressure of 58
mbar [0.84 psi].
n
Observe the maximum connection flow pressure of 65 mbar [0.94 psi].
n
If the pressure is higher, turn off the gas supply to the device and do not
carry out any commissioning.
