Install the horizontal ue pipe with a slope of approx. 3° (6 cm/m) towards the boiler.
Route the horizontal air supply with a 3° slope towards the outside – provide the
air inlet with a wind protector; permissible wind pressure at the air inlet 90 Pa. The
burner will not start if the wind pressure is higher. After the support bend (23), the ue
can be routed in DN80 inside the shaft. A exible ue pipe DN83 can be connected
downstream of support bend (23).
