95% Efficient Gas Furnace & Venting for a Sealed Foamed Attic https://stream.echo6.co/videos/watch/0027f55d-e8c0-43ea-949b-755a83666c1a In this video my HVAC contractor Gilbert Rosipal from AirRite shows us the inner workings of a 95% efficient gas furnace. You'll see the concentric pipe used for the sealed combustion chamber and the pvc vent pipe through the roof. We'll also discuss why we like to hang our units from the rafters rather than sitting them on the attic floor. -Matt Risinger Principle of an Austin Texas based High Performance Builder and Remodeling Company www.risingerhomes.com Wed, 10 Jun 2026 10:04:16 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://stream.echo6.co 95% Efficient Gas Furnace & Venting for a Sealed Foamed Attic https://stream.echo6.co/client/assets/images/icons/icon-512x512.png https://stream.echo6.co/videos/watch/0027f55d-e8c0-43ea-949b-755a83666c1a All rights reserved, unless otherwise specified in the terms specified at https://stream.echo6.co/about and potential licenses granted by each content's rightholder.
