Handling ceramic fiber materials

REMOVAL OF COMBUSTION CHAMBER LINING

• To avoid electric shock, disconnect electrical

supply before performing maintenance.

￿WARNING

The combustion chamber insulation in this appliance contains ceramic fiber material. Ceramic fibers can be converted to cristobalite in very high temperature applications. The International Agency for Research on Cancer (IARC) has concluded, “Crystalline silica in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1)”. Normal operating temperatures in this appliance are below the level to convert ceramic fibers to cristobalite. Abnormal operating conditions would have to be created to convert the ceramic fibers in this appliance to cristobalite.

The ceramic fiber material used in this appliance is an irritant; when handling or replacing the ceramic materials it is advisable that the installer follow these safety guidelines.

Avoid breathing dust and contact with skin and eyes.

•Use NIOSH certified dust respirator (N95). This type of respirator is based on the OSHA requirements for cristobalite at the time this document was written. Other types of respirators may be needed depending on the job site conditions. Current NIOSH recommendations can be found on the NIOSH website at http://www.cdc.gov/niosh/homepage.html. NIOSH approved respirators, manufacturers, and phone numbers are also listed on this website.

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

Apply enough water to the combustion chamber lining to prevent airborne dust.

Remove the combustion chamber lining from the water heater and place it in a plastic bag for disposal.

Wash potentially contaminated clothes separately from other clothing. Rinse clothes washer thoroughly.

• To avoid severe burns, allow the water heater to

cool before performing maintenance.

Water heater operation –

•Do not block flow of combustion or ventilation air to the water heater.

•Should overheating occur or gas supply fail to shut off, do not turn off or disconnect electrical supply to circulator. Instead, shut off the gas supply at a location external to the appliance.

•Do not use this water heater if any part has been under water. The possible damage to a flooded appliance can be extensive and present numerous safety hazards. Any appliance that has been under water must be replaced.

NIOSH stated First Aid.

Eye: Irrigate immediately.

Breathing: Fresh air.
