Product Description

These are OEM Security Duravent flue extension connectors.  There are two different flue extensions available from the drop down menu.  The 6CA works with chimney that has a 1″ insulated wall (ASHT & Duratech) whereas the 6XCA is certified for chimney with a 2″ insulated wall (Security Secure Temp S2100 & Duratech Premium).

Security Duravent Part Numbers: 

• 6CA : ASHT & Duratech Chimney that has a 1″ Wall (Sometimes referred to as 6DTC-CA). This replaces old part number 6UP
• 6XCA: Secure Temp 2100 & Duratech Premium Chimney that has a 2″ Wall.  This replaces old part number 6UP.

Part Description: The flue extension adapts the insulated chimney to either single wall or double wall smoke pipe.  The old part – 6UP – is no longer available and has been replaced by these two parts instead.
