ƽ WARNING
NOTICE
When servicing appliance –
• To avoid electric shock, disconnect electrical supply
before performing maintenance.
• To avoid severe burns, allow appliance to cool before
performing maintenance.
Appliance operation –
• Do not block flow of combustion or ventilation air to
the appliance.
• 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 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.
Appliance water –
• Thoroughly flush the system (without appliance
connected) to remove sediment. The high-efficiency
heat exchanger can be damaged by build-up or
corrosion due to sediment.
• Do not use petroleum-based cleaning or sealing
compounds in the appliance system. Gaskets and seals in
the system may be damaged. This can result in
substantial property damage.

Handling ceramic fiber materials
REMOVAL OF COMBUSTION CHAMBER LINING
ƽ 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 appliance
and place it in a plastic bag for disposal.
Wash potentially contaminated clothes separately from
other clothing. Rinse clothes washer thoroughly.
NIOSH stated First Aid.
Eye: Irrigate immediately.
Breathing: Fresh air.
