SAFETY
4 • Electric Tankless Water Heater
precau ons are par cularly important.
According to a na onal standard, Ameri-
can Society of Sanitary Engineering
(ASSE 1070), and most local plumbing
codes, the water heater’s temperature
set point should not be used as the sole
means to regulate water temperature
and avoid scalds.
Properly adjusted Thermosta c Mixing
Valves installed at each point of use
allow you to set the water heater’s
set point to a higher se ng without
increasing the risk of scalds. A higher
temperature can help provide proper
water temperatures for appliances such
as dishwashers and washing machines.
WARNING
Fire Risk
To reduce the risk of a
fire that could destroy
your home and seri-
ously injure or kill people:
• D o not store things that can burn
easily such as paper or clothes next
to the water heater.
• Be sure the water heater’s cover
is in place. This cover keeps debris
from entering and potentially being
ignited, and helps keep any internal
fires from spreading.
• Keep the water heater from becom-
ing wet. Immediately shut the water
heater off and have it inspected by
a qualified person if you find that
the wiring or control board have
been exposed to water in any way
(e.g., leaks from plumbing or leaks
from the water heater itself). Such
leaks can damage property and
could cause a fire risk. If the water
heater is subjected to flood condi-
tions or has been submerged in
water, the entire water heater must
be replaced.
• Make electrical connections prop-
erly according to the instructions on
page 13. Use a UL listed or CSA
approved strain relief. Connect the
ground wire to the ground lug. (The
ground lug is identified by a green
and white ground label inside the
water heater.)
Water Contamination Risk
Do not use chemicals that could
contaminate the potable water sup-
ply. Do not use piping that has been
treated with chromates, boiler seal, or
other chemicals.
