CAUTION When installing the burner, it should be noted that the loose fill insulation and fiber chambers are made with ceramic fibers. Currently, there are no known chronic health effects in humans associated with long term exposure to ceramic fibers. The International Agency for Research on Cancer IARC based on its review of studies that injected ceramic fiber into the abdomens of hamsters and rats have classified fibrous glass wool, mineral wool both rock wool and slag wool and ceramic fiber as group 2B carcinogens. A group 2B agent is considered by IARC to have the possibility of being carcinogenic to humans. IARC has also classified these fibrous materials as group 2A carcinogens when they have undergone long term exposure to temperatures greater than 18000F. A group 2A agent is considered to have the probability of being carcinogenic to humans. For these reasons, we suggest the use of a 3M 9900, 3M 8710 or equivalent mask when working with any ceramic fiber products.
