Can I cap off unused 6" diameter wall oven vent duct at ceilin
Hello. I could really use some help from the HVAC forum. I thank you for reading this and commenting.
Our kitchen has a 6" diameter vent duct leaving the top of a tall double oven cabinet, then continues up another 14" through a soffit. After that I don't know where it short term goes, but assume long term it connects with cooktop ducting run ending in a 1000 cfm exterior roof fan. We are redoing our kitchen and wish to cap this duct off (currently it doesn't even serve to vent the ovens anyway-disconnects).
Do you HVAC folks see any problem with capping this duct off at the ceiling and plastering over? As I don't know where the fork in the total run is, I can not address that split (like remove it etc). We will be installing a new 1000 to 1200 cfm exterior blower above the new rangetop or range and using this areas existing duct.
Any problems you foresee with this? I don't see what choice we have really when the soffit and tall cabinet come out.
