WARNING
Electrical Shock Hazard
Electrical shock can cause severe injury, death or
property damage. Disconnect the power supply
before beginning installation or changing the
wiring to prevent electrical shock or damage to the
equipment. It may be necessary to turn off more than
one power supply disconnect.
All electrical wiring is to be done in accordance with
local codes, or in the absence of local codes, with:
1) The National Electrical Code ANSI/NFPA No.
70 - latest Edition, or 2) CSA STD. C22.1 “Canadian
Electrical Code - Part 1.” This appliance must be
electrically grounded in accordance with these codes.
WARNING
MagnaTherm units must be installed in
accordance with the procedures detailed in this
manual, or the LAARS Heating Systems warranty
will be voided. The installation must conform to
the requirements of the local jurisdiction having
authority, and, in the United States, to the latest
edition of the National Fuel Gas Code, ANSI
Z223.1/NFPA54. In Canada, the installation
must conform to the latest edition of CSA
B149.1 Natural Gas and Propane Gas Installation
Code, and/or local codes. Where required by the
authority having jurisdiction, the installation
of MagnaTherm boilers must conform to the
Standard for Controls and Safety Devices for
Automatically Fired Boilers, ANSI/ASME CSD-1.
Any modifications to the boiler, its gas controls, or
wiring may void the warranty. If field conditions
require modifications, consult the factory
representative before initiating such modifications.
