Maximize your ease of installation with the new Noritz No Roof Kit. Our newest accessory is designed to make your tankless installation faster and easier than ever, without having to make the climb to your roof. Simply install using your existing 3” or 4” B-vent and your tankless is ready to provide your home with endless hot water.
• NRK-1 is designed only for installation inside of the B-Vent wall. Do not use it for other installation method.
• Keep out of direct sunlight.
• Any work done incorrectly or not described in this manual can leave parts in the B-Vent and be difficult to remove. In this case, access to the roof may be required.
