How to seal this?






When the furnace turns on air comes pouring out of this gap? Is this normal or should be be closed up?

Thanks.

There should have been a foam seal under that flange.
Or at least some foil duct tape.

apply and let set up before turning on.

Use foil duct tape to seal it off. I would not suggest using silicone caulk unless it was of the fireproof variety seeing as you are very close to the heat exchanger and the excessive heat may break down the normal silicone caulk. But foil duct tape should work just fine.

100% silicone tolerates heat pretty well....which is why it's so popular in the kitchen now.

caulking tube or roll check Graingers #6JD51 and more screws their rubberized backed tape that you can run around the top of that furnace opening then drop the duct there down and screw away.any duct tape right over the screws will dry out and you'll be back .the pressure of the air especially in the heating mode is right off the fan and the highest in the system

Foil tape is good if put on neat. I've seen tape that was 4" wide to seal
a little seam. If put on right it can look good. Mostly it looks crappy.
You will not see clear 100% silicone.
BTW it looks like it can be screwed down more.

Funny seeing as I had the same concern a few months ago. Like everyone noted I put some spare metal tape I had over it.

I also had another question. For my furnace instead of the solid pipe/union I have a yellow shielded flex line going in and it smells like a tiny bit of gas at the entrance. Is that normal? I was doing ceiling work upstairs and was near a register that was directly above the furnace and could of sworn I smelt a tiny bit of gas as well.

I went the ugly tape way... Even though I have some silicone caulk sitting here. (I checked its rated up to 400 F) I just felt the tape was easier and I don't care how it looks.

Thanks everyone for the tips and help. This site rocks.

Not sure. I just purchased the house last year and I've been busy with a newborn. Just getting around to all the fun house projects. But my guess is the builder the home is only 7 years old.

Foil tape, since your A-Coil sits in there, and makes it easy to remove it for service, where as with caulk, you have to run a knife around to separate the plenum from the unit.

Can you post a shot farther back, showing the unit from the floor to the supply plenum. Looks like they placed the B-Vent in front of the access panel for the A-Coil. You can start a "blog" in project showcase to keep everyone posted on happenings and what you are doing with the changes, to make the home yours.

So how did the other projects from 2012 turn out?
