Oval stove pipe?

Hi all,

We bought an old wood stove off of craigslist - it's a cute stove, with a "Montgomery Ward" tag on the back. See the attached picture.

Our stove guy came to hook it up today, but didn't have any pipe that would fit it. It has a semi-oval opening, the inside dimensions are 3 5/8 x 6 7/8.

6" pipe, even crimped didn't fit in. Any ideas? Do these old stoves really need a custom adapter? I haven't been able to find anything online.

EDIT: using string, I measured the bottom of the beveled opening to be equivalent to a 5.25" round pipe. Can't find 5.25" round anywhere!

Thanks!

Did I post in the correct topic?

no this forum is for pellet stoves not wood stoves. But someone here will know you can repost it the wood forum good luck

This should be the adapter you need.....

you may have to crimp the pipe a little extra, I believe the holes on your outlet on the stove are for securing the adapter. you most definately want to secure that pipe to the stove with screws. Here's what the pipe crimpers look like..



Rather than buying crimpers for one time use (I own a set because I use them often, for stove pipe and down spouts), find a local sheet metal shop that can crimp it for you. If all else fails, maybe a local sheet metal shop can make the adapter for you......

Are you sure it doesn't go outside? My stove has an oval outlet, which a slightly squished 8" pipe fits perfectly on the outside of.

I have used needle nose pliers in lieu of crimpers, Just grab an inch or so of the pipe end, squeeze the pliers, and twist a bit, working around the pipe.

Scotty - thank you - I wil try that, though it will certainly take some crimping. (I actually have one of those tools, from putting in an HRV system.) Should I use stove cement to seal it? I imagine the crimps would allow air in/out.

FanMan - yes, it goes inside. Otherwise, you wouldn't be able to get to the screw holes.

If there are any old time family owned hardware stores left in your area they often still have stove pipe equipment around and can crimp and make custom sizes and fittings.

The guy who tried to install it says he tried crimping 6" pipe and it didn't go, but I will try again.

Is it typical for old stoves to have a non-standard pipe size?

You can use stove cement (it certainly doesn't hurt ), I've also heard other people would pack tin foil into the fitting area (roll it up kinda like a cigarette), and cement over top of that. Some people use tin foil as a gasket material between every pipe joint in single wall pipe. I guess it seems to help cut back on air leaks.....
