Thank you for viewing. This is an Osaka Gas gas fan heater, model 140-9385, pure white. It is suitable for up to 15 tatami mats (wooden) / 21 tatami mats (concrete). Manufactured by Rinnai Corporation. Purchased in the fall of 2018 for approximately 50,000 yen. I am selling it because the gas outlet is no longer available due to home renovations. Please refer to the photos and the product website for details. It was working without any problems before. I cannot confirm its operation now because I don't have a gas outlet. Please check the operation after the product arrives, and if there are any issues, please contact me via message first before leaving a rating. I have cleaned it as much as I could reach, but there is some dust inside the black air filter on the back (inside the main unit). Please check the photos. Includes: Gas fan heater, instruction manual, Gas cords (1m and 2m - only one can be used. Please let me know if you don't need one; the price will not change) Please consider this item, understanding that it is a used product.
