What is the characteristic of Class C venting systems?

The characteristic of Class C venting systems is that they are typically made of single-wall pipe composed of galvanized steel. This design is specifically intended for venting non-condensing appliances that produce flue gases which do not exceed certain temperature limits and corrosive potential.

Galvanized steel provides adequate protection against rusting and degradation, making it a suitable material for the relatively lower temperatures often found in these applications. The use of single-wall design also makes assembly simpler and reduces installation costs. Each feature of this venting system is geared toward ensuring safe exhaust venting while adhering to building code requirements and safety standards.
