The model 224046, Raised Horizontal Termination Kit is comprised of concentric bi-flow vent pipe and is only to be used as part of the vent system for a Rinnai LS, RL, RV or V Series Tankless Water Heater. It is recommended that this kit be used in colder climates when the wall penetration point is less than 12” above the soil grade. This kit has the capability to raise the termination point 23.5” to 31.5”. Please note that Rinnai R98LSi models require separate intake and exhaust pipes and do not require this vent type of vent system. This vent fitting has a metal interior pipe for the exhaust and a plastic exterior pipe to draw air from outside for combustion. This vent fitting requires zero clearance to combustibles. This vent fitting should NOT be used with the Rinnai RC or RU Series 95% Efficient Condensing Tankless Water Heaters!
Seal rings with maximum temperature 400°F (approx. 200°C)
The Rinnai vent system is unique because it uses a concentric bi-flow piping system. Most tankless water heaters require separate intake and exhaust pipes that are run independently from each other to the outside of your home. The Rinnai vent system is special because it has one pipe inside the other. You will not be able to retain or re-use the exhaust pipe from a standard or high efficiency tank type water heater. Rinnai's unique vent system must be run from the top of the tankless water all the way out of your home. Because of this requirement, exhaust vent pipe from existing standard or high efficiency "tank" type water heaters can't be re-used with a Rinnai Tankless Hot Water Heater.
