Install the horizontal flue with approx. 3° slope (6 cm/m) towards the boiler. Route the
horizontal air supply with a 3° slope 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. Inside the duct downstream of the support bend (23), the flue
can be routed in DN 80. A flexible flue DN 83 can be connected downstream of the support
bend (23).
