• NIOSH stated First Aid:

Eye: Irrigate immediately.

Breathing: Fresh air.

￿ 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

Checking equipment –

Upon receiving equipment, check for signs of shipping damage. Pay particular attention to parts accompanying the appliances which may show signs of being hit or otherwise being mishandled. Verify total number of pieces shown on packing slip with those actually received. In case there is damage or a shortage, immediately notify the carrier.

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.

Do not use this appliance 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.

Warranty –

Factory warranty (shipped with unit) does not apply to units improperly installed or improperly operated.

Experience has shown that improper installation or system design, rather than faulty equipment, is the cause of most operating problems.

1.Excessive water hardness causing a lime/scale build-up in the copper tube is not the fault of the equipment and is not covered under the manufacturer’s warranty (see Water Treatment and Water Chemistry).

2.Excessive pitting and erosion on the inside of the copper tube may be caused by too much water velocity through the tubes and is not covered by the manufacturer’s warranty (see Boiler Flow Rates and Temperature Rise for flow requirements).
