* Values for upper/lower boiler output, relative to a CO
boiler water temperature of 60 °C. The chimney stack dimensions must be calculated in accordance
with DIN 4705. For flue gas temperatures below 160 °C, connect the boiler to highly insulated
chimney stacks (heat conductivity resistance class I acc. to DIN 18160 T1) or suitable,
moisture-resistant flue gas systems, which have been type-approved.
