Note

Before starting the appliance and/or checking the supply pressure and burner pressure, you must fill (5 "Filling") the appliance.

Caution

Before starting up for the first time or after conversion, you must always check the supply pressure and burner pressure.

Note

The easiest way to check the gas pressures is by using two pressure gauges. This procedure assumes that these two gauges are available.

If the appliance is to be run on a different gas category than the factory preset gas category (see type plate) then you must first convert (4 "Conversion to a different gas category") the appliance.
