NOTICE
Maxitrol vent limiting devices eliminate the need to run vent piping to the outside. Vent limiting devices are designed for
use indoors and in spaces where limiting the amount of gas escapement due to diaphragm failure is critical. Vent limiting
devices should not be used outdoors if they are exposed to the environment. Vent protectors are available for all outdoor
applications to ensure proper vent protection.
