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.
