Product Overview

BrassCraft's Coated Corrugated Steel Tankless Installation Kit contains everything you need to connect most tankless water heaters to your gas and water supply. Tankless Service Valve features a captive nut and washer to eliminate the potential for component loss during installation. Additionally, the captive washer won’t kink or misalign during installation. The new compact, slim-fit valve design is a perfect fit for a variety of installations - recessed or cover boxes. Integrated drain valve allows instant water flow control and hassle-free maintenance of your tankless appliance. BrassCraft’s ProCoat stainless steel gas connector is engineered with added safety in mind. The proprietary polymer coating is designed to withstand prolonged exposure to harsh household chemicals, UV rays and salt. ProCoat is applied to the corrugated stainless steel connector using advanced powder-coat technology. The coating is applied only after the connector has been 100% leak tested, prior to nut and fitting assembly. This process results in the most complete corrosion resistance available.

Rated 5 out of 5 by from All In One Kir !!! This is a great kit for installing your tankless heater, Comes with all necessary hardware to make you life easier, As well as leaving it set up for easy clean outs after installation.(tankless heaters should be flushed with white vinegar every 12 months to remove scaling) With this kit and a small pump you can easily descale your heater with little effort. Also makes installation and service much easier, Brasscraft makes a quality product and this seems to be no exception. How To Clean Your Tankless Water Heater: Pour approximately five gallons of food grade white vinegar into a 5 gallon pail. Place the inlet hose of the pump, and the drain hose from the hot water heater into the pail. Open the drain valves and turn on the pump. Allow solution to circulate for approximately 45 minutes to an hour. Your coils inside the heater will sparkle like new.
