Questions & Answers

Instructions say to connect duct connector and roof cap and then insert assembly into the hole in...

Instructions say to connect duct connector and roof cap and then insert assembly into the hole in the roof in order to trace the outline of the flange before trimming the shingles. However it's not clear in the instructions whether that's just a convenient way to position the roof cap properly for measurement. Should the connector and roof cap be installed as a unit or is the connector inserted through the hole and the roof cap just installs over it? Thanks.
Asked by: CaptRich
Having installed hundreds of these, I find the easiest way to install one is to cut a 5.5" wide by 6" high square hole on the roof, with the top of the hole being at the very bottom of a course of roofing shingles (go into attic and put a 3" nail through roof at middle of bay for a reference for cutting the hole). With a flat bar, remove the one or two roofing nails which will be in the way of sliding the vent up under two courses of shingles. Once the nails are removed do a dry fit to make sure it fits well, butter the bottom with tar, put in place, secure with two nails and tar all the way around. Now go into attic and twist round connector in place (I suggest turning counter clockwise-seems to works better that way), it will make a solid clicking sound once it is secure-it can then rotate freely 360 degrees but will not come off. I always use a 4" insulated hose (not the one provided), so I connect inner hose to round connector with a 4" band clamp, then secure the insulated sheath of the hose over that with a 24" zip tie. After that I attach to the bath fan the same way.

How can I be sure that air is venting out and duct is not clogged? I hear fan running but have had major steam build up in bathroom?
Asked by: Valerie
Have someone turn on and off the fan. While you watch from outside the house. If your eyes are strong enough you should see the flap blow open by the fans’ force. If not use binoculars. Or the zoom feature on your phones’ camera. If not your metallic flex hose may have been disconnected, never connected or most likely kinked.

I have a very powerful bathroom fan that puts out 130cfm with a 4" duct. Will this vent be alright for my fan or do I need a bigger vent?

I have about the same strength fan. This device works fine. This is a decent quality product. I used it at a rental location.

Rain comes down though fan What should I do to fix?
Asked by: Rich
The roof cap has a backdraft damper behind the screen. Check to see that it is operating correctly. If it isn't, wind could blow rain into the vent. If the vent is mounted on a flat roof, this could also contribute to the problem.

I also used the 6” r6 insulation, overlapped the insulation and used metal duct tape to keep it together. Better quality then the aluminum vent sold there for $10 more
