WARNING Scalding
The water in the DHW tank can be heated to tempera-
tures in excess of 149 °F (65 °C). There is a risk of scalding
at outlet temperatures in excess of 110 °F (43 °C).
Ensure you do not come into contact with the water
when discharged.
WARNING Burns
Touching hot components can lead to burns.
When working on hot components, always wear protec-
tive working clothing and safety gloves.
The pipework connected to the DHW outlet of the appli-
ance can reach temperatures in excess of 149 °F (65 °C).
CAUTION
!
Install temperature and pressure protective equipment
required by local codes and no less than a combina-
tion temperature and pressure relief valve certified by a
nationally recognized testing laboratory that maintains
periodic inspection of production of listed equipment or
materials, as meeting the requirements for Relief Valves
and Automatic Gas Shutoff Devices for Hot Water Supply
Systems, ANSI Z21.22. This value must be marked with a
maximum set pressure not to exceed the marked max-
imum working pressure of the water heater. Install the
valve into an opening provided and marked for this pur-
pose in the water heater, and orient it or provide tubing
so that any discharge from the valve exits only within 6
inches above, or at any distance below, the structural
floor, and does not contact any live electrical part.
Caution
!
Only operate the appliance when the DHW tank has been
filled.
Caution
!
Keep the appliance installation room free from air con-
taminated with oil or salt and corrosive or explosive sub-
stances.
2.4

Heat exchanger loop

The SB E tanks have an indirectly fired heat exchanger loop. This
may be used in a variety of scenarios which include boiler loops,
geothermal systems, radiant floor loops, etc. Since the interior
of the heat exchanger is uncoated carbon steel, they must be
configured in a closed loop.
Use only a mixture of inhibited propylene glycol and de-ionized
water. The percentage of the glycol in the mixture depends upon
the climate. Some areas require that the propylene glycol be
GRAS, which is a food grade liquid (Heat exchanger type SW,
AWWA Fluid Class II - see MSDS for handling instructions).
