preparInG for the InstallatIon
1. Read the “General Safety” section of this manual first and
then the entire manual carefully. If you don’t follow the safety
rules, the boiler may not operate safely. It could cause DEATH,
SERIOUS BODILY INJURY AND/OR PROPERTY DAMAGE.
This manual contains instructions for the installation, operation,
and maintenance of the electric boiler. It also contains warnings
throughout the manual that you must read and be aware of.
All warnings and all instructions are essential to the proper
operation of the boiler and your safety. READ THE ENTIRE
MANUAL BEFORE ATTEMPTING TO INSTALL OR OPERATE
THE BOILER.
Detailed installation diagrams are in this manual. These
diagrams will serve to provide the installer with a reference
for the materials and method of piping suggested. IT
IS NECESSARY THAT ALL WATER PIPING AND THE
ELECTRICAL WIRING BE INSTALLED AND CONNECTED
AS SHOWN IN THE DIAGRAMS.
Particular attention should be given to the installation of
thermometers at the locations indicated in the diagrams as
these are necessary for checking the operation of the heater.
Be sure to turn off power when working on or near the electrical
system of the heater. Never touch electrical components
with wet hands or when standing in water. When replacing
fuses always use the correct size for the circuit. See page 12
through 14.
The principal components of the heater are identified on page 8.
The model and rating plate on page 9 interprets certain markings
into useful information. Both of these references should be used
to identify the heater, its components and optional equipment.
2. The installation must conform with these instructions and the
local code authority having jurisdiction and the requirements
of the power company. In the absence of code requirements,
follow NFPA-70 (current edition). The National Electrical Code
may be ordered from: National Fire Protection Association, 1
Batterymarch Park, Quincy, MA 02269.
3. If after reading this manual you have any questions or do not
understand any portion of the instructions, call the toll free
number on the back cover for further assistance.
A sample rating plate and barcode tag are shown on page 9 of
this manual. In order to expedite your request, please have the
serial number and item ID from the barcode tag available for the
technician.
4. Carefully plan your intended placement of the boiler. Examine
the location to ensure the boiler complies with the “Locating the
New Boiler” section in this manual.
Installation and service of this boiler requires ability equivalent
to that of a licensed tradesman or qualified agency (page 2) in
the field involved. Plumbing and electrical work are required.
5. For installation in California this boiler must be braced or
anchored to avoid falling or moving during an earthquake. See
instructions for correct installation procedures. Instructions may
be obtained from California Office of the State Architect, 1102 Q
Street, Suite 5100, Sacramento, CA 95811.
6. Massachusetts Code requires this boiler to be installed in
accordance with Massachusetts 248-CMR 2.00: State Plumbing
Code and 248-CMR 5.00.
