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

Any modifications to the boiler, its gas controls, or
wiring may void the warranty. If field conditions
require modifications, consult the factory
