1) Safe, reliable operation of this boiler depends upon installation by a professional heating contractor in strict accordance
with this manual and the requirements of the authority having jurisdiction.
•
In the absence of an authority having jurisdiction, installation must be in accordance with this manual and the latest
edition of Installation of Oil Burning Equipment (ANSI/NFPA31).
•
Where required by the authority having jurisdiction, this installation must conform to the latest edition of Standard for
Controls and Safety Devices for Automatically Fired Boilers (ANSI/ASME CSD-1).
2) Make sure that a properly sized chimney is available which is in good condition. Consult the authority having
jurisdiction, Part VI of this manual, and ANSI/NFPA31 for additional information on venting requirements.
3) Make sure that the boiler is correctly sized. Use an industry accepted sizing method such as the I=B=R Guide RHH
published by the Air-Conditioning, Heating and Refrigeration Institute (AHRI).
4) In some cases, boilers installed at altitudes above 2000ft may require a different burner configuration from that at sea level.
Consult the local Crown representative for more information.
