SECTION 1.
General Information
WARNING
This manual supplies information on the application,
installation and operation of the indirect water
heater unit. A complete instruction manual of the
operation of the hydronic boiler (Document 1080) is
supplied along with this manual. Both manuals
should be reviewed completely before proceeding
with the installation.
• Failure to follow the instructions provided may
result in personal injury, death or substantial
property damage.
• Any modifications to the boiler, water tank, gas
and water connections, or wiring may void
warranty.
• Consult the factory or local factory
representative with any questions or problems
regarding this equipment.
Hazards and Your Safety — Hot Water
Can Scald!
Consumer Product Safety Commission and some
states/provinces recommend a temperature setting of
130°F (54°C) or less. The water heater thermostat is
factory set to approximately 120°F (49°C). If
thermostat will be set above factory setting, install an
anti-scald valve at either the water heater or at each
hot water faucet.
• Tempering valves are not anti-scald valves since
they do not have a positive shutoff in case cold
water supply fails. They are not recommended
for shower/tub service. If needed, install an anti-
scald valve at each shower/tub.
• Water heated to a temperature suitable for
clothes washing, dish washing and other
sanitizing needs can scald and cause permanent
injury.
• Children and elderly, infirm, or physically
handicapped persons are more likely to be
injured by hot water. Never leave them
unattended in a bathtub or shower. Never allow
small children to use a hot water tap or draw
their own bath. If anyone using hot water in the
building fits this description, or if state/province
laws or local codes require certain water
temperature at hot water taps, take special
precautions:
Install an anti-scald valve at water heater or at
each hot water faucet, bath, and shower outlet.
Use lowest practical temperature setting.
• Studies have indicated that dangerous bacteria
can form in potable water distribution system if
certain minimum water temperatures are not
maintained. Contact local health department for
more information.
