Designer’s Guide / Knight XL Boiler
Chapter 6 – Other Details of
Great Importance
STANDARD CODES, STANDARD CONSTRUCTION
The Knight XL boiler is design certified to the latest edition of ANSI Z21.13. The third party
certification was performed by CSA International and the boiler bears the American Blue Star
emblem and the Canadian Blue Flame emblem. The heat exchanger inside the boiler conforms
to the latest edition of the ASME Boiler and Pressure Vessel Code, Section IV and the vessel
bears the ASME “H” Stamp.
The installation of a heating boiler is governed by local boiler codes. The boiler shall be installed
in accordance with those installation regulations and shall be carefully followed in all cases.
Authorities having jurisdiction shall be consulted before installations are made. The local code
may require a feature on the boiler above and beyond the ANSI requirements. Check the list of
factory installed options on page 30. Again, some of these options are factory installed and must
be specified on the original purchase order. Review the local code especially in regard to the
venting requirements.
In the absence of local codes, U.S. installations shall
conform to the latest edition of the National Fuel Gas
Code, ANSI Z223.1. In Canada, the installation must
comply with the Canadian Gas Association Code,
CAN/CGA-B149.1 and/or B149.2 and/or local codes.

OPTIONAL CODES, ADDITIONAL CONSTRUCTION
Many local authorities require the boiler installation conform to CSD-1, the American Society of
Mechanical Engineers Safety Code for Controls and Safety Devices for Automatically Fired
Boilers. CSD-1 is subject to different interpretation by different boiler inspection offices.
The Knight XL boiler must be factory trimmed to meet CSD-1 code to your specifications.
Factory Mutual is a popular insurance code. The well known Industrial Risk Insurers code has
been purchased by General Electric Company and replaced with their own “GE Gap” code. For
Knight XL boilers both Factory Mutual and GE Gap are met by being configured for CSD-1.
The Knight XL boiler must be factory trimmed to meet Factory Mutual or GE Gap.
STATE CODES, ADDITIONAL CONSTRUCTION
All states have their own boiler installation code, but some states have codes that require special
equipment on the boiler itself. For example, California, Massachusetts, Minnesota and Kentucky
have state codes that require additions to Lochinvar products. Check with your local Lochinvar
sales office or Lochinvar Customer Service for details.
