Nice! This is one of the few videos that show the duct installation for a lower level bathroom /no attic access. Was confused about how to find best path from exterior wall to fan, but looks like it will require some 'exploratory holes' to figure out, lol. Thanks!
Haha glad the video was helpful and yes usually 1 to 2 holes and you'll find the direction you need to go
Awesome Tutorial. I am doing the same right now. Thank you so much for taking the time to make the video.
Glad the video can be helpful! Appreciate the video feedback
When using silicone on any external fixture, always leave a small section at the bottom open or without silicone. If any water gets in,(like from the top) it will have a place to get out.
You could also run a bead of silicone in the shape of an upside down U around your hole in the wall on the siding, then when you push the vent in place it will create the gasket and you won't need any silicone on the edges. The four screws with washers were a nice touch.
If you crimped the edges of the hard duct on your vent, your flexible duct would slip right on. Then use HVAC or duct foil tape to seal the connection.
Thanks so much for these tips! I hadn't thought about leaving a small section for drainage in the sealant. Makes so much sense when you think about how a few other exterior facades are detailed like brick weeps. Also, the hvac hard duct was giving me a hard time, I'm going to use the crimping technique. Working on a buddies house soon and it will come in handy
Good vid, thanx!
Thanks for the video feedback!
Getting ready to do mine tomorrow. Thank you for this
@Bo_Dicaire good luck with the install!
Good job, but the pig tails need to be inside a metal box. Outside is a fire hazzard.
Good tip! I'll research and adjust those as needed to the correct location!!
a toilet flange.....really
Worked great! Perfect diameter and provides a thermal break. Get past the toilet part...it's a plastic flange with predrilled screw connection locations with built in thermal break. I could have gotten it customer made for couple hundred dollars maybe and called it a plastic flange 😀
Epic idea. Gonna do the same for mine, wrap some foil tape around
@patchworkmountains that'd be a good extra addition
