TL;DR
Vent connector rise is the vertical height a vent connector gains between the appliance's draft hood outlet and its connection into the chimney or common vent, the geometry that lets hot flue gases establish draft before turning horizontal. Venting tables in the fuel gas code rate capacity by this rise along with vent height and lateral length, and more of it means stronger flow for a given appliance.
What it means
Vent connector rise is the vertical height a vent connector gains between the appliance's draft hood outlet and its connection into the chimney or common vent, the geometry that lets hot flue gases establish draft before turning horizontal. Venting tables in the fuel gas code rate capacity by this rise along with vent height and lateral length, and more of it means stronger flow for a given appliance. Installers steal as much as the space allows, ideally a foot or more straight up off the appliance, because a connector that turns flat immediately is prone to spillage on cold starts.
