This fitting provides a three-way junction with a 4 x 4 x 3 inch configuration, allowing installers to branch a 3-inch lateral off a 4-inch main vent run without disrupting system flow geometry. At 10 inches in length, it maintains a compact profile in tight mechanical spaces. Licensed HVAC technicians and plumbers install this type of fitting when routing gas appliance venting through walls, attics, or utility chases where multiple appliance connections are required on a single vent stack.\u003c\/p\u003e\n\u003cp\u003eThe 104133 is suited for residential and light commercial gas venting applications using double-wall Type B vent pipe. It is typically installed on gas furnaces, water heaters, boilers, or other Category I gas appliances that require a common venting arrangement. The fixed wye design routes the branch connection at a set angle, making it appropriate for planned vent layouts where the branch direction is determined during system design rather than in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFixed wye configuration with 4 x 4 x 3 inch inlet and outlet sizing\u003c\/li\u003e\n  \u003cli\u003ePart of the RV Series Type B double-wall gas vent system\u003c\/li\u003e\n  \u003cli\u003e10-inch overall length for consistent rough-in dimensions\u003c\/li\u003e\n  \u003cli\u003eDesigned for common-venting of multiple Category I gas appliances\u003c\/li\u003e\n  \u003cli\u003eFixed outlet angle simplifies layout in pre-planned vent runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Type B gas vent systems.

All connected appliances must be shut off and allowed to cool before disassembling or modifying any vent section. Type B vent fittings must not be used with gas appliances that produce flue gas temperatures exceeding the rating of the vent system. Verify that combined appliance inputs and vent sizing comply with ACCA or appliance manufacturer venting tables before finalizing the installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: RV Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Fixed Wye\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 4 x 4 x 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuitable For Use With\u003c\/strong\u003e: Type B Gas Vent Systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SELKIRK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 104133\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SELKIRK","offers":[{"title":"Default Title","offer_id":51138907078962,"sku":"104133","price":87.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305533284.jpg?v=1778265635","url":"https:\/\/voomisupply.com\/products\/selkirk-104133-rv-series-fixed-wye-4x4x3-type-b-gas-vent","provider":"Voomi Supply","version":"1.0","type":"link"}
