Customer Questions and Answers for Exhaust Kit by Whirlpool

Hi Tim. Where the exhaust vent hooks to the blower wheel housing there is a clamp that holds it together with a screw mounting the clamp to the base keeping it tight. Then at the back of the cabinet there is a screw that is right above the vent which mounts the back of the vent to the cabinet holding that end as well. Are you referring to the lower sides of the cabinet that has the 4" dia. Knock outs that need to be punched out the rest of the way? For cabinet rigidity they remain intact until you need to use them with your kit. You will use a punch and hammer along with vise grips to remove the knockout the rest of the way. Make sure to secure the new vent route so it does not rattle during operation. Use met6aql tape on all joints to prevent leaks. Thank you.
