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.
