Installation, Use and Care Manual

Operation
Before operating this water heater, be sure to
read and follow these instructions, as well as
the warnings printed in this manual. Failure
to do so can result in unsafe operation of the
water heater resulting in property damage,
bodily injury, or death. If you have any
problems reading, following or difficulty in
understanding
the instructions in
this
manual, STOP, and get help from a qualified
person.
Do not turn on the water heater unless it is
filled with water. Do not turn on water heater
if cold water supply shut-off valve is closed.
After the water heater has been plumbed and
wired, it is now ready to be set for automatic
operation.
FILLING THE HEATER COILS
Make sure all drains valves on the cold or hot
water supply piping are closed.
Open the nearest hot water faucet and any
shutoff valves on the domestic hot water supply
piping from the heater’s domestic hot water outlet
(the top copper pipe connection).
Open the shutoff valve on the cold water supply
piping to the heater’s domestic cold water inlet.
When water discharges from faucet, close it.
Check for system leaks and repair if necessary.
Any other water faucets fed by this heater may be
opened to purge air from their supply piping, and
then shut off after a steady flow of water is
observed from the faucet.
OPERATING THE WATER HEATER
After the system has been manually purged of its
air,
and
all
components
(valves,
vents,
controllers) have been set properly, the Eco
ULTRA boiler can be started. Never operate this
heater until this has been done.
Safety and energy conservation are factors to be
considered when setting the water temperature
on the controler. The most energy efficient
operation will result when the temperature setting
is the lowest that satisfies the needs consistent
with the application.
The maximum setting for the boiler water supply
to the heater coil is 210°F. The boiler supply
temperature should be from 20°F up to 40°F
higher than the domestic water temperature.
More exactly, the boiler supply temperature
should be higher than the domestic supply
temperature by more than half the boiler
temperature drop (TD) through the TURBOMAX.
There is a Hot Water Scald Potential if the
controler is set too high.
When this water heater is supplying general
purpose hot water requirements for use by
individuals, a thermostatically controlled
mixing valve for reducing point of use water
temperature is highly recommended to
reduce the risk of scald injury.
Valves for reducing point-of-use temperature
by mixing cold and hot water are also
available. Consult a licensed plumber or local
plumbing authority for further information.
When the temperature of the boiler water in the
Eco ULTRA boiler is below the setting on the
control or aquastat, the circulator should start and
the boiler water will be heat by the renewable
energy source. The electric elements will turn
only if the temperature continue to decrease.
When the temperature of the boiler water in the
boiler reaches the temperature setting on the tank
control, the boiler and circulator should turn off.
On initial start-up with a cold tank, a considerable
amount of time may be required for the tank to
reach desired temperature. Check the
temperature at a hot water faucet soon after the
burner has completed the first heating cycle.
Note that setting to a lower setting will not have
an immediate effect. The stored boiler water will
first have to be used. Additional checks of the
water temperature should follow completion of a
cycle. Further adjustments may be necessary as
you use your water heater and space heating
system.
