Roof top concentric termination kits are approved for use with the boiler model.
Installation of the vertical roof top termination must follow the installation
instructions supplied with the venting material manufacturer. Care must be taken
to install the termination kit a minimum horizontal distance of 10' (305 cm) away
from any portion of the building and a minimum of 2 feet (61 cm) above the roof
line plus the anticipated snow line.
Caution
Take care installing Concentric Rooftop Termination kits when the outdoor
temperature drops below 5°F/-15°C. Possible blockage of the combustion air intake
can occur when the outdoor temperature drops below this temperature.

Caution
Vent termination clearances in this section are code minimum, or IBC-
recommended minimum requirements, and may be inadequate for your installation.
Building envelope details must be examined carefully. Take action to avoid
moisture entering building structures. Serious structural damage may occur if
adequate precautions and clearances are not considered. These precautions apply
to neighboring structures as well as to the structure the boiler(s) are installed in.
