What materials are approved for joining single wall vent connectors?

Joining single wall vent connectors must be done with materials that ensure a secure and reliable connection, as these connectors play a crucial role in venting gases safely from appliances. Sheet metal screws are the appropriate choice for this purpose because they provide a strong and permanent attachment that can withstand temperature variations and mechanical stresses typically encountered in venting applications.

Sheet metal screws create a tight connection and help to prevent any potential leaks of combustion gases, which is essential for maintaining safety standards. Moreover, they are easier to remove and replace than some other methods, like adhesives or rivets, should repairs or modifications be necessary.

Other materials, such as duct tape or silicone adhesives, lack the necessary durability and strength required for a safe and long-term connection in venting systems. Using such materials could lead to failures that compromise the integrity of the venting system, posing significant safety hazards.
