(1) Relative to NCV (net calorific value).
(2) Values measured in an open area; in a real installation, the thermal flow may reach greater distances than those given here (depending on the height of the ceiling
and its thermal insulation).
(3) The operating temperature of the appliance components is 0 °C / +60 °C.
