Please note:
The Vitodens boiler has passed the zero inches vent clearance to combustibles testing requirements dictated by the armonized Standard
ANSI Z21.13. CSA 4.9.2000 and therefore is listed for zero clearance to combustibles when vented with a single wall special venting
system (AL-29-4C material). The zero inches vent clearance to combustibles for the Vitodens boiler supercedes the clearance to
combustibles listing that appears on the special venting system label.

Use standard friction loss method for pipe sizing. Observe boiler maximum and minimum flow rate limitations. If system flow rate exceeds
boiler maximum flow rate (as stated above), falls below the minimum flow rate or if system flow rate is unknown, Viessmann strongly
recommends the installation of a low loss header. An alternative method may be used, such as primary secondary piping using closely
spaced tees. A low loss header offers additional benefits not provided by a pair of closely spaced tees. Viessmann therefore strongly
recommends and prefers the use of a low loss header over closely spaced tees. See page 13 for low loss header information.
