Install the horizontal flue with approx. 3° fall (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
in DN80 can be connected.
