This product contains fiberglass wool and ceramic fiber

materials. Airborne fibers from these materials have been

listed by the State of California as a possible cause of can-

cer through inhalation. Use special care when handling

ceramic fiber (chamber lining and base insulation) materials.

Ceramic fibers can be converted to chrystobalites, a sub-

stance listed as a probable cause of cancer. Suppliers of

fiberglass wool products recommend the following mea-

sures be taken when handling these materials:

Precautionary measures:

• Avoid breathing fiberglass dust.

• Avoid contact with skin and eyes.

• Use a National Institute for Occupational Safety and

Health (NIOSH) approved dust/mist respirator.

• Wear long-sleeved, loose fitting clothing, gloves and eye

protection.

• Wash work clothes separately from other clothing. Rinse

washer thoroughly.

Removing the burner may generate airborne fiber concen-

tration requiring additional protection.

First aid measures:

• Eye contact - Flush eyes with sterile water to remove

foreign objects. If irritation or other symptoms persist,

seek medical attention.

• Skin contact - Wash affected areas gently with soap and

warm water after handling.

bodily injury or death.

The heaters for which this manual has been written have

been approved with the minimum clearances to com-

bustibles as listed in Figure 1.
