(cont.)
■ Condensing boilers with Viessmann balanced flue system:
Order the balanced flue pipe with connector for the flue gas temper-
ature sensor separately.
■ For condensing boilers with on-site flue pipe:
The aperture required for the flue pipe installation must be designed
and approved on site. Install the flue gas temperature sensor into a
stainless steel sensor well (on-site).
