qualified service technician.
FAILURE TO ADHERE TO THE GUIDELINES IN THIS
MANUAL CAN RESULT IN SUBSTANTIAL PROPERTY
DAMAGE, SEVERE PERSONAL INJURY, OR DEATH.
The combustion chamber insulation in this product 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 inhaled in the form of quartz
or cristobalite from occupational sources is carcinogenic to
humans (Group 1).” DO NOT, UNDER ANY CIRCUMSTANCES,
OPEN THE COMBUSTION CHAMBER OF THIS APPLIANCE!
The combustion chamber of this appliance may be opened
by a qualified service technician ONLY. FAILURE TO FOLLOW
THESE INSTRUCTIONS CAN RESULT IN SUBSTANTIAL
PROPERTY DAMAGE, SEVERE PERSONAL INJURY, OR
DEATH.
A. Appliance Operation
• Do not block flow of the
appliance exhaust vent or
intake pipe.
•
Should overheating
occur or gas supply fail to
shut off, do not turn off
or disconnect electrical
supply to the circulator.
Instead, shut off the
gas supply at a location
external to the appliance
following the instructions
on page 2.
•
Do not use this appliance
if any part has been
under water. Immediately
call a qualified service
technician to inspect the
appliance and replace any
part of the control system
or gas control that has
been under water.
B. Primary Water
•
Do not attempt to clean the heating system. Call a
qualified service technician for service.
• If you notice any leaks, immediately call a qualified
service technician. Leaks in appliance or piping must be
repaired at once.
Hydronic systems that use glycol as heat transfer fluid must be
serviced periodically. Glycol can break down over time, become
acidic, and attack gaskets and seals in appliances. This can result
in property damage, severe personal injury, or death.
Each glycol manufacturer has different recommendations for
testing and replacement. Do not test glycol quality yourself.
Have your qualified service technician check glycol quality
during annual servicing. If you are unsure when your glycol was
last tested, call a qualified service technician to test and replace
glycol, if necessary.
C. Freeze Protection Fluids (Does Not Apply to VWH
Models)
