Power (“Side Wall”) Venting - Important Note
Two problems arise when any oil-fired appliance is power vented:
• There is sometimes an accelerated rate of soot buildup on the oil burner cad-cell, spinner etc.
• 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 FSZ 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 Company will assume no responsibility for damage
to siding, etc. from a power vented oil-fired boiler. This applies regardless of the cause of the sooting.
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). Installations in Canada comply with the requirements
of CSA B139-04 – Installation Code for Oil-burning Equipment.
• 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 VII of this manual, and ANSI/NFPA31 for additional information on venting requirements.
3) Make sure that the boiler is correctly sized. Do this by totalling the surface area of all radiators in the system (in sq. feet). To
this, add any other space heating (not DHW) loads. Select a boiler having a net rating just larger than this total heating load.
Note: 1 sq. ft of radiation is equal to 240 BTU/hr.
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.
