4.7 Conversion to natural gas
This appliance is shipped from the factory for use with nat-
ural gas.
If the appliance has been converted to propane gas be-
fore, you have to convert it to natural gas again.
Check the orifices for the right nozzles and, if required, re-
place them. See "Replacing the main control nozzles".
Adjust the minimum gas flow. See "Setting the minimum
gas flow". The optimum setting is achieved when the
height of the small flame is approx. 1/8" (3 to 4 mm).
Set the pressure regulator for natural gas. Turn the spring
plate the other way around as shown in "Setting the pres-
sure regulator for propane gas".
Save the orifices removed from the appliance for future
use.
