This is an original factory Rheem Hybrid Water Heater outlet duct adapter part number 17829 or SP17829 and are BRAND NEW IN BOX and are OEM (original equipment manufacturer) produced including the adapter, foam self stick gasket, and screws. Beware of non-OEM knock-off 3D printed adapters as they may void your water heater warranty and do not come with foam gasket for proper sealing and fit.
This attaches to the output duct side of your Rheem hybrid water heater and allows an 8 inch duct to be attached to it and routed to the area you wish the cold output air of the heater to go to. They also fit Ruud and Richmond hybrid water heaters (all are made by Rheem). If your water heater looks like the one shown with the yellow background, this duct is correct.
It comes with 6 self tapping screws and a self-adhesive gasket along with installation instructions (shown in pic above).
We buy these in bulk direct from Rheem and physically stock these in Phoenix, AZ to ensure that they are shipped out in a timely manner. Before buying from another seller, ask if they have stock or just drop ship from manufacturer who is often out of stock so can take an additional 2-5 weeks before it is shipped.
It measures about 12.75 inches wide at bottom (left to right), 12.25 inches wide on side (top to bottom) and about 1.75 inches at its deepest point. The outlet hole is about 8 inches in diameter. There is an install shown with a custom wall niche (inset) which we can custom make to your required dimensions if needed for you (3D printed) and purchase through an Ebay sale.
