The combination saves space and allows a by-pass to be added into many short spaces between the supply and return plenums.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThe RTB features a mounting flange with and adhesive seal to seal tight against any duct surface to eliminate any air leakage and meet all duct leakage standards.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eTo simply install, cut a round hole the diameter of the RTB. Peel off the paper strip on the back of the flange and center and place over the opening of the round hole. The adhesive backing will hold the by-pass in place and if metal duct is used, sheet metal screws can be used to secure the RTB to the duct. The RTB must be sized to handle the amount of CFM that maintains a constant volume of air through the HVAC System. To determine this size required use ZONEFIRST’s By-Pass Calculator or Design Guide.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0010\/8458\/8093\/files\/RTB.pdf?v=1674871321\" title=\"manual\" rel=\"noopener noreferrer\" target=\"_blank\"\u003e\u003cimg alt=\"Manual\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0010\/8458\/8093\/files\/3_962c143d-be16-4728-95d1-009109e43a36.png?v=1647307385\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul class=\"tabs-content\"\u003e\u003c\/ul\u003e","brand":"Hydro Solar Innovative Energy","offers":[{"title":"8","offer_id":44865250656502,"sku":"50080301","price":153.92,"currency_code":"USD","in_stock":true},{"title":"10","offer_id":44865250722038,"sku":"50080302","price":162.62,"currency_code":"USD","in_stock":true},{"title":"12","offer_id":44865250754806,"sku":"50080303","price":173.93,"currency_code":"USD","in_stock":true},{"title":"14","offer_id":44865250787574,"sku":"50080304","price":189.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0010\/8458\/8093\/products\/rtb-round-take-off-by-pass-damper-38550451978486.png?v=1674871431","url":"https:\/\/hydrosolar.ca\/en-us\/products\/rtb-round-take-off-by-pass-damper","provider":"Hydro Solar Innovative Energy","version":"1.0","type":"link"}
