Note:The Vitodens 100-W boiler has passed the zero
inches vent clearance to combustibles testing
requirements dictated by the boiler Harmonized
Standard ANSI Z21.13. CSA 4.9 (latest edition)
and therefore is listed for zero clearance to
combustibles when vented with a single-wall
special venting system (AL-29-4C material) or
UL/ULC-listed CPVC gas vent material.
The zero inches vent clearance to combustibles for
the Vitodens 100-W boiler supercedes the clearance
to combustibles listing that appears on the special
