The DIVERSITECH dt-ec-1 is a PVC flue cap designed to terminate direct-vent and PVC flue pipe systems in residential and light commercial HVAC applications. It mounts at the exterior flue outlet to prevent rain, debris, birds, and insects from entering the vent system while allowing combustion exhaust gases to discharge freely. Measuring 10 inches tall and 12.5 inches wide, the dt-ec-1 is constructed entirely of PVC, making it resistant to condensate, corrosion, and the acidic flue gases common in high-efficiency heating equipment. HVAC technicians and plumbers install this cap as part of new system commissioning or as a replacement on existing PVC vent terminations.
The dt-ec-1 is suited for use on PVC vent systems typically found on high-efficiency gas furnaces, boilers, and water heaters that exhaust through 40 PVC pipe. It is appropriate for both residential installations and light commercial settings where PVC flue pipe is the approved venting material. The cap is installed at the exterior wall or roof penetration where the flue terminates, providing weatherproofing and pest exclusion without restricting exhaust flow.
Designed as an OEM-style replacement or new-installation flue cap for residential and light commercial PVC vent systems on high-efficiency gas appliances.
Installation is typically performed by a licensed HVAC technician or plumber as part of a venting system installation or service call. Power down and shut off gas to the appliance before servicing any connected vent components. Secure the cap per the appliance manufacturer venting instructions and applicable local codes, including IFGC and equipment-specific venting requirements. Do not use this cap on metal flue systems or appliances requiring B-vent or double-wall metal vent terminations.
