ures can be attributed to improper water treatment or overtreatment.

Boiler Codes and Standards
Boilers must be installed and operated in accordance with applicable
codes and standards. The local code authorities will refer to one or
more of the industry codes, especially the American Society of Me-
chanical Engineers (ASME) boiler code.

Other references will meet
the standards of the American Gas Association (AGA), the Hydronics
Institute (HYDI), the American Boiler Manufacturers’ Association
(ABMA), and insurance companies, such as Factory Mutual (FM) (par-
ticularly with respect to burner systems). Underwriters’ Laboratories
(UL) provides certification for some of the control and safety devices,
such as relief valves. The proposed design of the boiler system should
be submitted to the owner’s insurance company to ensure compliance
with requirements.
