WARNING: At all times the gas pressure must be within +/- 1 mBar of the
rated stated on the data plate. For example a G20-20mBar Natural Gas
Appliance must be 19mBar to 21mBar. Failure to observe this will render the
appliance unreliable and possibly dangerous.
5. Ensure all other gas appliances in the home are switched off. With the
