    Questions & answers

    Hi there I have a Capella 18 Plus LPG heater. Is a vent or type of flue required with unit whn in operation. Regards Kev Kevin · 2025-04-26
    Hello Kevin, Thank you for this product. The Rinnai Capella is a portable unit that has a vent at the bottom, which pushes the heat back into your room, this draws air through the rear vent vent then passes over the heat exchanger which heats the cool air and returns this hot air via the vent at the front, you may download the user manual on our website for extra information on how to use and care for your new heater. I hope this information will assist you when shopping with us at Appliances Online. Our Sydney-based team is available 24/7 to assist you at Ph: 1300-000-500. Colin Jones, Appliances Online
