It allows the chimney to offset around framing, beams or other obstructions while keeping the run continuous and code compliant. B-vent is a gas-only, double-wall metal chimney with a smaller diameter than wood-burning chimneys, making it the ideal solution for fireplaces that require complicated or space-restricted venting runs. The double-wall construction keeps the outer surface cooler while efficiently carrying exhaust gases outdoors.\u003c\/p\u003e\u003cp\u003eB-vent is the most economical way to vent a gas masonry fireplace, and its compact diameter makes it easy to route through walls, attics and chases. The double-wall construction resists corrosion while keeping clearances to combustibles small. Use only with gas appliances and complete the system with matching pipe, firestops and a listed termination cap. Because it is designed to work with Mason-Lite fireplaces, it installs cleanly alongside the rest of your build without guesswork or field modification.\u003c\/p\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e45° Elbow\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eElbows are used to offset installation to avoid obstructions such as rafters and joists\u003c\/li\u003e\n\u003cli\u003eAdjust easily from 0° to 45°\u003c\/li\u003e\n\u003cli\u003eDouble-wall gas vent construction\u003c\/li\u003e\n\u003cli\u003eFor gas appliances only\u003c\/li\u003e\n\u003cli\u003eAvailable in 10\" and 12\" diameters\u003c\/li\u003e\n\u003cli\u003eTwist-lock connection between components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eMason-Lite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eItem Number\u003c\/th\u003e\n\u003ctd\u003e12BVL45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eElbow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eVenting Type\u003c\/th\u003e\n\u003ctd\u003eB-Vent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eSize (Diameter)\u003c\/th\u003e\n\u003ctd\u003e12\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eDocuments \u0026amp; Files\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0772\/9646\/8151\/files\/Mason-Lite-20pg-Product-Catalog-v3-MAR22-WEB-1.pdf\" target=\"_blank\" rel=\"noopener\"\u003e2024 Catalog\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Mason-Lite","offers":[{"title":"Default Title","offer_id":57897961947319,"sku":"12BVL45-1","price":400.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/9646\/8151\/files\/mason-lite-b-vent-12-45-degree-adjustable-elbow-1.webp?v=1793252009","url":"https:\/\/www.efireplacedirect.com\/products\/mason-lite-b-vent-12-45-degree-adjustable-elbow","provider":"efireplacedirect","version":"1.0","type":"link"}
