Step 8. Once the termination is positioned, secure it to the chase
flashing using the stainless steel screws provided, through the pre-
punched attachment holes in the attachment tabs of the termination.
Be careful not to over tighten the screws so as to strip out the chase
flashing. In the event of a strip, a larger screw can be used so long
as it is stainless steel. DO NOT use common sheet metal screws, as
they will corrode over time and the termination will no longer be
secure at that point.

MAINTENANCE
As part of an annual inspection, the termination should be checked for
any foreign debris, animal or insect nests, or material of any kind which
may have become lodged in it. The exterior of the termination should be
visually inspected for damage of any kind.
In the event of damage to the termination, it should be replaced with a
new termination. All screw attachments should be checked to insure
they have not loosened over time and they should also be checked for
the water tightness of their silicon seal. The termination must be
removed to clean the chimney. Following cleaning, reinstall the termi-
nation and inspect as detailed in this document.
