Built from AL 29-4C stainless steel and rated to UL 1738 standards, this termination box fits 5-inch round rigid vent pipe and is suitable for natural gas or liquid propane appliances. The gasketed, fusion-welded construction eliminates the need for sealant, reducing installation time and eliminating callbacks from leaking joints. Licensed HVAC technicians install this component as the exterior exit point of a horizontal vent run.\u003c\/p\u003e\u003cp\u003eThis termination box is engineered for Category II, III, and IV gas-burning appliances where the maximum vent gas temperature at the appliance outlet does not exceed 550 degrees F. Typical applications include unit heaters, high-efficiency gas furnaces, and high-efficiency gas water heaters vented through a single-wall, horizontal pipe configuration. A minimum clearance of 3 inches to combustibles is required. Always verify local codes before beginning installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-inch round rigid pipe end for Category III stainless steel single-wall systems\u003c\/li\u003e\n\u003cli\u003eUL 1738 rated and AL 29-4C stainless steel construction\u003c\/li\u003e\n\u003cli\u003eGasketed connections with fusion-welded pipe seams — no sealant required\u003c\/li\u003e\n\u003cli\u003eAirtight seam with smooth interior finish for consistent airflow\u003c\/li\u003e\n\u003cli\u003eRated for natural gas and liquid propane appliances\u003c\/li\u003e\n\u003cli\u003eHighest pressure rating in its category — exceeds industry standard by more than five times\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eEngineered for use with Category II, III, and IV gas-burning appliances, including unit heaters, high-efficiency gas furnaces, and high-efficiency gas water heaters, where single-pipe horizontal venting with 5-inch round rigid Category III stainless steel pipe is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with the appliance manufacturer instructions and all applicable local codes.
