DC/HC SERIES BOILERS
WARNING
HOT WATER CAN SCALD!
Water Temperatures over
125°F / 52°C can cause severe
burns instantly or death from
scalds.
Children, disabled, and
elderly are at highest risk of
being scalded.
• Never leave then
unattended in or near the
shower, bathtub or sink.
• Never allow small children
to use a not water faucet or
draw their own bath.
To avoid any potential scald
hazard or if codes require
specific water temperatures
at the hot water faucet, the
installer must:
•
Install the factory supplied
thermostatic mixing valve at
this appliance and ensure it
is working properly.
AND
•
Set the thermostatic
mixing valve to the lowest
temperature which satisfies
your hot water needs.
TO AVOID INJURY:
•
Feel and adjust water
temperature before bathing
or showering.
•
Water drained from the
system drain valve may be
extremely hot.
•
Make sure all connections
are tight.
•
Direct water flow away from
any person.
WARNING
Close fill valve after any
addition of water to the
system, to reduce risk of
water escapement.
WARNING
Water quality has a significant
impact on the lifetime and
performance of an IBC Boiler
heat exchanger.
Improperly prepared water in
a heating circuit may cause
damage to the heat exchanger
through corrosion or fouling.
Repeated or uncontrolled
water fills will increase the
potential for damage.
High levels of dissolved
solids or minerals may
precipitate out of the fluid
onto the hottest part of the
heat exchanger, impairing
heat transfer and resulting in
overheating and premature
failure. The amount of solids
that may form on the heat
exchanger will depend on
the degree of hardness and
the total water volume in the
system. A high water volume
system with a low hardness
count may cause as much
damage as a system with less
volume and higher hardness,
so it is recommended to treat
water so as to remove all
dissolved solids. Other water
chemistry allowable limits are
as follows:
•
Acidity pH is to be between
6.5 and 8.5
•
Chloride is to be less than
125 mg/l
•
Iron is to be less than 0.3
mg/l
•
Cu less than 0.1 mg/l
•
Conductivity is to be less
than 400μS/cm (at 25°C)
•
Hardness is to be 7 Grains
or less
IMPORTANT: Ensure that
these limits are acceptable
for the other water-side
components in the system.
