INSTALLATION
The manufacturer’s warranty does not cover any damage or defect caused by installation, or
attachment, or use of any special attachment other than those authorized by the manufacturer into,
onto, or in conjunction with the water heater. The use of such unauthorized devices may shorten
the life of the boiler and may endanger life and property. The manufacturer disclaims any
responsibility for such loss or injury resulting from the use of such unauthorized devices
SAFETY MEASURES
Any commercial installation will be equipped with
a safety valve that limits the maximum working
pressure to the maximum design pressure of the
tank. The maximum operating pressure of the
VoltMax Boiler with a power of
90kW and less
is
30 psi or 70 psi, depending on the options chosen.
The maximum operating pressure of the VoltMax
boiler with a power of
more than 90kW
is 60 psi or
125 psi, depending on the options selected. See
boiler data sheet for maximum operating pressure.
The boiler is equipped with an automatic high limit
temperature control set at 210°F (99°C) and a
second manual high limit temperature settable.
This electric boiler is designed to operate at a
maximum operating temperature of 200 ° F (93 °
C). The boiler is designed for use in a hot water
heating system only.
The heat transfer fluid must be water or an
antifreeze water / propylene glycol solution or
an antifreeze water / ethylene glycol solution
specially designed for heating systems. The
maximum concentration of solution must be a
maximum of 50%.
LOCATION
The electric boiler should be installed in a clean,
dry location. Long hot water lines should be
insulated to conserve water and energy. The
electric boiler and water lines should be protected
from exposure to freezing temperature.
The boiler can be mounted vertically or
horizontally directly on a solid surface.
The electric boiler must be located or protected
to avoid risk of physical damage, such as from
moving vehicles, flooding, etc.
The location must have sufficient ventilation to
maintain an ambient temperature not exceeding
80°F (27°C).
To prevent condensation on the boiler walls,
boiler temperature should not be maintained
below the condensation temperature (dew-
point temperature) of the ambient. The
operating temperature of the boiler must not
be lower than the condensation temperature
(dew temperature) relative to the ambient
humidity content.
CLEARANCES
For adequate inspection and servicing the
following minimum clearance is necessary:
Table 8 : Boiler Clearances
Sides**
3 inches / 76 mm
Bottom
0 inches / 0 mm
Top*
32 inches / 813 mm
Front
24 inches / 610 mm
Back
3 inches / 76 mm
* A minimum clearance of 32 inches. For units
equipped with 18 kW elements (25 in. For 15 kW
elements) is required for possible replacement of
heating elements.
** The left side of the control panel, where the
boiler ON / OFF switch is located, must remain
visible after installation. Otherwise, a label
indicating its location must be affixed to the
control panel indicating its position.
PIPING INSTALLATION
The location of the inlet and outlet piping shall
conform to the various configurations shown in
Figure 1. You will find typical connection
diagrams
to the Figure 3, Figure 4 and
Figure 5.
The VoltMax boiler is designed to be operated
on a closed-circuit piping system. Therefore, it
should not be used to heat open air tanks
