What gauge of galvanized metal is required for a 10" single wall vent connector?

For a 10" single wall vent connector, the requirement is that the metal used must be sufficiently durable to handle the heat and pressure of the exhaust gases without deforming or failing. The gauge of metal refers to its thickness, with a lower gauge number indicating a thicker and stronger material.

A 22 gauge galvanized metal is the standard requirement for that size vent connector. This thickness provides the necessary strength and resistance to corrosion, which is crucial for the venting system's effectiveness and longevity. Thicker metals, such as 20 gauge, while more robust, are not typically required for this application, making 22 gauge the right choice as it balances strength with practicality and cost.

Choosing a gauge that is too thin, like 24 or 26 gauge, would compromise the structural integrity of the vent connector under operational conditions. Therefore, utilizing 22 gauge is optimal for ensuring safety and compliance in the venting system.
