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 UL/ULC certified
special venting system. 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.

The back or side clearance shall be increased if

piping installation is required.

Recommended minimum service clearances
