III Before Installing
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.
Power (“Side Wall”) Venting - Important note
Two problems arise when any oil-fired appliance is power vented:
1. There is sometimes an accelerated rate of soot buildup on the oil burner cad-cell, spinner etc.
2. There is a potential for severe damage to the side of the structure in the event that the boiler operates at a high smoke
level. This can happen for many reasons, some of which are out of the control of both the installer and appliance
manufacturer.
Crown Boiler Company recommends the use of a chimney to vent the KSZ series boilers. If a power venter must be used, it
is the responsibility of the installer and power vent manufacturer to “engineer” the power vent system. crOWn BOIlEr
