Important Notices Regarding Products

Notice for the users of "α (Alpha) Kamadodaki", a gas rice cooker with electric heating function

Rinnai has found that the possibility of partial burning of some of the gas rice cookers with electric heating function that were produced from August 2005 to September 2009. When alkaline cleanser is attached to gas supply inlet and the area remains wet for a long time, it causes the erosion of the inlet. It is rare; however, there are cases that a crack appears and a very small quantity of gas leaks, which results in the partial burning of product.
There are four cases where a product was partially burned due to this phenomenon. However, there is no case that the damage was extended beyond a product.

We are deeply sorry to cause trouble to the users of the product concerned. Until an inspection is completed, when a user detects an odor of gas, the corrosion of a gas supply inlet, or the difficulty in rotating a gas supply inlet, please immediately suspend the use, turn the gas off at the mains, and contact us.

We are very sorry to cause our customers trouble. We solicit for your understanding and cooperation.
