Two problems arise when any oil-fired appliance is power vented:
x There is sometimes an accelerated rate of soot buildup on the oil burner cad-cell, spinner etc.
x 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 FWZ 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.
