Before placing boiler in its installation
location, ensure all necessary
accessories are installed.
Minimum Clearances
Recommended minimum service clearances
Refer to the illustrations on the left hand side.
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 4.9.2005 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 venting system label.
