Low Heat Injection Pressure Checks

Switch the control to Low Heat

Check and adjust if necessary the Outlet pressure to 3.5
mbar (G20) or 5 mbar for Groningue(G25) & 14 mbar for
propane (G31)(fig.54)

After the adjustment of the low heat, re-verify the high
heat

re-position the stoppers and close the pressure ports.
