Can I install an external vent fan or in-line fan to boost the performance of my hood ventilation equipment?
Do not install in-line or external fans to boost a hood that has its own power unit. In general, attempting that type of "boost" will not be effective. Also, most cooking ventilation products are designed with fan switches matched to the original motor amp ratings and would not support the increased amp draw from additional motor installations. This type of tampering voids the original manufacturer's warranty. If you want a remote/extended fan, there are hood products made for that type of installation.
