Domestic Hot ater Production Via a Boiler
Ensure the instructions and requirements with respect to the boiler control
and system accessories are observed.
Domestic hot water production can occur via boiler only.
The ma imum heating supply temperature is 230 °F / 110 °C, the
ma imum operating pressure is 150 psig on the tank.
1. Set the desired domestic hot water
temperature (140°F / 60°C for
example) on the boiler control, or on
the aquastat of the DHW tank
(depending on the type of installation
you have).
2. The boiler water supply temperature
for domestic hot water production is
set on the boiler control. It should be
approximately 27°F / 15°C above
the desired domestic hot water
temperature.
5167 516 v1.2
The operating aquastat and any
secondary high limit aquastat of the
tank must be set such that the DH
temperature inside the tank never
exceeds 203 °F / 95 °C.
ARNING
Domestic hot 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.
Feel water before bathing or
showering.
Temperature limiting valves are
available and must be used where
domestic hot water storage tank
temperatures exceed 140°F / 60°C.

Shut-down
If domestic hot water production is not desired and the risk of freezing
temperatures in the mechanical room e ists, please contact your heating
contractor.
Temperature and Pressure Relief Valve
HEnsure there is never any type of
valve or an obstruction of any kind
between the tank and the
temperature and pressure relief valve
(T&P valve), or between the T&P
valve and the discharge line outlet.
The discharge line must be oriented
to enable unobstructed and visible
flow of discharge water toward a
floor drain.
HIf you observe water being released
from the discharge pipe of the
temperature and pressure relief valve,
contact your heating contractor
immediately.
HThe valve test lever must be operated
at least once per year by the heating
contractor to ensure that waterways
are clear. A licensed professional
heating contractor shall reinspect the
T&P valve at least once every three
years. Failure to inspect can result in
unsafe temperature or pressure
build-up, which can result in
substantial product/property damage,
serious personal injury or loss of life.
Service and Cleaning
Inspection and (if necessary) cleaning
of tank must take place within 2 years
of initial start-up and as required
thereafter. Reinspection time must not
exceed 2 years.
The internal cleaning of the domestic
hot water tank including its potable
water connections may only be
performed by a licensed professional
heating contractor.
Clean tank enclosure with a commercially
available alcohol-based glass cleaning
agent and a soft clean cloth.
There are no user serviceable parts on
this equipment.
We recommend an annual (min. every
two years) inspection of the built-in
magnesium anode. The inspection must
be performed by a heating contractor.
If a water softener system is used in
the domestic cold water inlet piping
into the tank, the water treatment
system should be inspected (serviced)
at the same time. If a drinking water
filter is used in the main line, the filter
cartridge should also be investigated.
All external equipment must be
serviced regularly and function
properly.
The possibility of mineral build-up on
the valve seat exists.
Report dripping or discharges from
the T&P valve to the heating
contractor immediately.
