STANDARD CODES, STANDARD CONSTRUCTION
The Power-fin water heater is design certified to the latest edition of ANSI Z21.10.3, the water
heater standard. The third party certification was performed by CSA International and the water
heater bears the American Blue Star emblem and the Canadian Blue Flame emblem. The heat
exchanger inside the water heater conforms to the latest edition of the ASME Boiler and Pressure
Vessel Code, Section IV and the vessel bears the ASME "HLW" Stamp.
The installation of an water heater with a storage tank is governed by local boiler and water
heater codes. The water heater and tank 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 water
heater above and beyond the ANSI requirements. Check the list of factory installed options on
page 35. Again, 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
Primarily, local building code inspectors inspect boiler installations. When reviewing water heater
installations, inspectors occasionally ask for the water heaters to comply with well known boiler
codes, such as CSD1, the American Society of Mechanical Engineers Safety Code for Controls
and Safety Devices for Automatically Fired Boilers. Also, they'll ask for Factory Mutual or "GE
Gap", popular insurance codes that call for CSD-1 requirements.
CSD-1 is strictly a space heating boiler code. Per CSD-1 code, Section CG-130, "Exclusions",
water heaters are exempt from the boiler requirements. The standard water heater built to the
ANSI Z21.10.3 requirements is acceptable.
STATE CODES, ADDITIONAL CONSTRUCTION
All states have their own boiler and water heater installation codes, but some states have codes
that require special equipment on the water heater itself. Currently, 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.
