General Venting Information
(continued)
Flashing and storm collar installation
Flashings and storm collars are field supplied. Flashings
and storm collars suitable for Type B vent materials (or
better) may be used.
To obtain flashings and storm collars, please contact
your local vent material supplier. Follow the installation
instructions supplied by the special venting manufacturer.
Follow local codes to properly isolate the exhaust vent
pipe when passing through floors, ceiling and roof.
Always check the marking on the pipe to make sure you
are using the correct material.
Additional Requirements for Stainless Steel Vent Pipe Material
Use stainless steel venting system (UL/ULC listed for
category IV) for horizontal or vertical venting of the
Vitocrossal boilers.
Contact one of the suppliers (see listing on right) to order.
Prior to installation, check that the correct single-wall
vent parts were ordered and supplied.
Exhaust vent/air intake connection to boiler
The vent connection to the Vitocrossal boiler may require
a starter stainless steel adaptor (supplied by others).
Combustion air intake
If using room air-independent venting system, the
combustion air intake kit must be used. Connect the air
intake pipe (from outdoors) to the adaptor provided.
If room air-dependent venting system is used, the air is
drawn into the burner inlet through the combustion air
inlet screens located on the side of the boiler.
For exhaust vent pipe material:
Do not use any other vent material.
IMPORTANT
Note:
For SS venting system order transition adaptors
from the above mentioned suppliers.
WARNING
The use of vent material other than listed UL/ULC
stainless steel and PPs positive pressure vent pipe and
fittings can cause property damage, severe personal
injury and/or loss of life.
