General Information
WARNING
The NeoTherm hydronic boiler must be installed in
accordance with the procedures detailed in this

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 NeoTherm boilers must conform to the

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.
