Note:
The Vitodens boiler has passed the zero
inches vent clearance to combustibles
testing requirements dictated by the
Harmonized 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.
IMPORTANT
A masonry chimney flue may be used to
route the venting system only if no other
appliance is vented in the same flue.
