3.11 Checking the supply
pressure and burner
pressure
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.
