Install the horizontal flue with a fall of approx. 3° (6 cm/m) towards the boiler. Route the
horizontal air supply with a 3° fall towards the outside – install the air inlet with wind
protection; permissible wind pressure at the air inlet 90 Pa. The burner will not operate
with higher wind pressure. In a duct, after the support bend (24), a rigid or flexible flue
can be connected.
