A. O. Smith’s Cyclone Mxi Common Venting Kit allows contractors to easily connect two commercial gas Cyclone Mxi water heaters with shared external venting, which reduces — by half — the number of wall penetrations needed for an installation. Popular for commercial installations such as restaurants and hotels, the modulating Cyclone Mxi is often paired with a second unit in high-demand applications to increase capacity.

Kits are available for use with both PVC and polypropylene venting systems. The vent kits are certified for use with all Cyclone Mxi tank sizes and require no power source.
