90° Elbow for Rinnai Ultra Series Condensing Tankless Water Heaters

The Rinnai RCi Series Tankless Water Heaters use concentric venting with an inner pipe which is designed to withstand the varying temperatures throught the years of a condensing heater operation. The Ubbink Rolux condensing concentric vent design is part of the direct vent system, and has been tested and approved by CSA, a third party testing agency.

Vent components consist of an outer plastic vent for air intake (5" diameter) and an inner polypropylene vent for the exhaust gases (3" diameter).

  •  No weld lines
  •  Not affected by scratches
  •  Dent and crease resistant
  •  Seamless extruded material
  •  Stable, thick-walled material
  •  Easier to cut thank stainless steel
  •  Thick-walled, casted elbows and adapters
  •  Seal rings with a maximum temperature of 400°F (approx. 200°C)
