Z-Vent Horizontal & Vertical Vent Kits & Components

These kits are intended for use with Category III and IV power vented appliances, including wall-hung tankless water heaters and high efficiency boilers, as well as storage type water heaters and floor standing cast iron boilers.
A flue-only kit is intended for use with a positive pressure (fan assisted) appliance which draws the intake combustion air from the surrounding environment, such as a large basement or a mechanical room with fresh air vent.
