Cold air intake hose - acceptable?

[Swed]

I was in lowes today. Finally got the allure 50 Delivered on Friday and am in the process of installing it so I picked up some 3inch hvac tubing while in lowes today.

What do you guys think, can this be used for the cold air intake? It looks like it's rated for up to 400+ Degrees.

Yup that works. It will get a lot of frost on it on a night like this.-9 here.

Should work fine, looks like the same stuff I that came with my OAK (outside air kit).

Thanks guys. I just wasn't sure if it was fire rated high enough for the air intake (I know air intake is not supposed to get hot but think they require some kind of rating in case something goes wrong) I know on my old Englander when I unhooked it I found a couple of pellets in the air intake hose. I don't know if something went wrong where it was subject to heat or how that happened so just want to make sure...

-9 ouch! We were in the single temps one night last week but bounced up to the mid 50s today (long island) ... but we are back in 20s tonight and the low 30s tomorrow Great for pellet stoves, not so great for the mind, lol. (summer person here).

We just got to a -20F dip last night. I wonder how an OAK would do in such low temp?

Mine gets condensation on it and I have to put a rag under it to catch the drips.

Mine is automotive exhaust flex pipe. Gets condensation when it gets below 10F or so. When it starts approaching -20F it gets frost. I too keep a towel on the floor behind the stove to catch the drips.

But much better drawing in the -20F air there, than through every crack and crevice in the rest of the house.

Should be fine. Air intake doesn't get hot at all

I've run mine for years, many times -20°F and colder. Like others say, you'll get some condensation, so a rag or two on the floor and all is good.

I had some of this stuff left over after putting a bunch on my car:

It works great on OAK intake lines. Wrapped it up and no condensation, even when the outdoor temperature is below zero. But I wouldn't recommend buying it just for an OAK because of the cost, unless you really want to get rid of that condensation.

I ended up picking up some of this from Home Depot, http://www.homedepot.com/p/Speedi-Products-3-in-x-96-in-Round-Aluminum-Flex-Pipe-EX-AF-396/202907340 only because it says it is non combustible and that is what Harman calls for. I had to have it shipped since Home Depot stores don't stock it. When I received it, it is flimsy. It bends and crushes easily so took some patience hooking it up to the wall thimble. The stuff at lowes although only rated to 400+ degrees was much more sturdy but still very easy to bend and work with. While I had the lowes hooked up for a week I kept an eye on it and it stayed totally cold, never even a hint of warmth so I am not sure if I really needed to change it out with the one from Home Depot but since Home Depots is rated non combustible, piece of mind and it is to code. Thanks for all the replies.. I hope this helps someone in the future doing a hookup.
