Heat resistant foil tape

[rakuz66]

Is there any type of heat resistant foil tape I can get to wrap my seams where the SS liner meets the elbow coming out of the stove? Or what else can I use? thanks.

Are you using one of these to connect the flex liner to stove pipe? http://www.chimneylinerinc.com/pic.php?pic=verticalapplianceconnector-lg.jpg&cap=Appliance Connector

Usually furnace cement is used to seal any air gaps between stove pipe connections, along w/ 3 screws per joint.

Yes, but the liner install was crappy and they used a 90 adjustable elbow from the stove to liner, so that's what I need to use until I change things up. A 15 will work, but I'm afraid it will be short. So, for this year, I'm going with what was there. Would love to wrap the knuckles on the adjustable though.

Does that tape handle those very high temps? Most adhesives don't hold up well under those extremes.

I heard it burns off, but I was hoping there was some kind of heat tape I haven't heard of yet.

Hey guys, if you use furnace cement for the joints, is it posible to clean them afterwards?

The furnace cement will knock right out of the joint when you take it apart for cleaning. Just slather a little back on during reassembly.

Great, cause I plan on re-doing everything next year. Any brand or type you think is good? thanks

This is absolutely not the place for a patched repair. There is a serious risk of the patch failing. It could happen at any time, including when you are sleeping.

Metal duct tape is definitely not to be used here. That elbow will see temps up to 900-1000 degrees. Metal tape is rated at 180-200F tops. The gap is too large for any cement patch. Get the proper connector and elbow. This is not a big deal to fix correctly.

Don't worry, This isn't a patch job, I am getting a new elbow.

Good to hear. We want you to stick around and be safe. I'm also very curious to see how the stove behaves with the new welds.

 

[rakuz66]

Yep, me too. I decided to wait until next year to insulate the liner and install a block off plate. Too much going on right now. That's why I asked about cleaning the furnace cement off. I also have that piece attached to my SS liner that is in the pic a few posts above. That will go directly into my new elbow.

Just as encouragement, a block-off plate really isn't that hard to do. I'd never done anything with sheet metal before I made mine and it went fine. Took a couple hours with tin snips, a straigt edge for bending & some silicon. Getting the stove/insert unhooked & out of the way is the biggest pain.

I bought a new stove top meter a couple of weeks ago and right there in the stove cement isle was Rutland brand stove tape for flues. It was a roll of metal tape that is supposed to be good enough for use on flues. I could just see someone using this stuff like a header wrap.

It's only rated to 600 degrees. Not sure why they call it flue tape because the info on it talks about wrapping "air ducts."

Here it is for sale on amazon.

Thanks for that info Pen. I checked on Nashua data sheets as this is the most common HVAC brand. Haven't seen or used the 3M product. I still would not use it on a flue collar or pipe which can see over 600F+ daily.

From 3M's website:
• Performance range from -65°F to over 600°F (-54°C to over 316°C). Adhesive will
gradually thermoset at high temperatures. As it thermosets, the adhesive mass
becomes firm and gradually loses its pressure sensitivity but will continue to hold the
tape in place.
