The gas consumptions refer to the calorific value at standard conditions at 15°C - 1013 mbar.
They comply with the european directives
90/396/CEE, 89/336/CEE, 73/23/CEE,
92/42/CEE and with the european specifi-
cation EN 483.
These appliances heat and supply domestic
hot water with a sealed forced draught
