A WORD ABOUT CERAMIC GLASS:

Your Kuma oil –burning stove has a glass front installed that is constructed of transpar- ent high temperature ceramic glass. When any type of fuel is burned, certain chemicals are re- leased in the combustion process. This release, combined with expelled moisture can cause a stress factor on the glass surface. Fuel oil has sulphur in it and the sulphur can contribute to this stressing phenomenon which results in micro-crazing. Micro-crazing appears as very fine stress fractures that look like fine spider webs. It generally does not indicate a structural problem with the glass– it is only cosmetic. As this is a by-product of combustion and not a defect in the glass itself, the glass on your stove is an item that is not covered under the warranty of this stove. There seems to be almost no issues of micro-crazing when burning #1 fuel oil or kero- sene. However, #2 grade fuels or diesel inherently have a higher sulphur content making it more susceptible to micro-crazing. There are other advantages to using #1 fuel, such as cleaner burning and less carbon build-up. Contact your dealer if you have any questions or need a glass replacement.
