SECTION 3 : INSTALLATION
The manufacturer’s warrant
y 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
3.1 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
(5 elements) 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
(10 elements) 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%.
3.2 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. Vertical
supports are provided and allow installation on
the floor; No wall bracket is included with the
equipment.
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
90°F (32°C).
3.3 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.
3.4 PIPING INSTALLATION
The location of the inlet and outlet piping shall
conform to the various configurations shown in
Figure 1. You will fi
nd typical connection
diagrams to the Figure 3, the Figure 4 and the
Figure 5.
