Adjustable high limit safety cut-out: 120/110/100 °C at R31 STAV, R32, R33 and R33/4 (not applicable to installations in Austria).

The chimney stack dimensions must be calculated in accordance with DIN 4705, or local regulations. For flue gas temperatures below 160 °C,
combustion equipment must be connected to highly insulated chimney stacks (heat conductivity resistance class I acc. to DIN 18160 T1) or use
suitable, moisture-resistant, type-tested, flue gas systems.
