NOTE:

Vent limiters are designed for use indoors and in spaces where limiting the amount of gas escapement due to diaphragm failure is critical. Vent limiters should not be used outdoors if they are exposed to the environment. 13A15 Vent Protector is available for outdoor use when vent protection is required and the vent limiter is protected from the environment. Vent limiters can only be installed in regulators for which they are certified. Vent limiters must only be installed directly into the vent connection of the regulator without intermediate pipe or fittings.
