OK to cut 3 inches off extension pipe?

[dreezon]

I'm ever so close to finishing the install of my Fireview; the only issue left is that the pipe between the Tee and the stove is about 3 inches too long. Is it OK to just cut the front end (the one that goes into the back of the stove) off?

There is a raised lip about two inches from the end, which would seem to be there to prevent the pipe going too far into the stove, but the pipe only went about 1 inch into the stove anyway. I'm pretty sure the diameter behind the lip is the same as the diameter in front of it. Is there any reason I can't cut it off behind the lip?

I'm doing the same thing - I thought the other end (crimped) goes into your stove, while the non-crimped end goes to the next piece of (crimped) stove pipe...

 

[dreezon]

If you have a crimped end, then, yes, that's the end that goes into the stove. The one that comes off my tee has a crimped end pointing toward the stove, but this piece of pipe is different. Neither end is crimped. The end you see is the smaller end, but it seems the overall dimension of the pipe is what the dimension of the crimped end would be. Am I making sense?

You can cut that end.
I use a circular saw with a thin abrasive cut-off blade.
Draw a line all the way around it with a Sharpie marker,
or wrap a piece of masking tape around it as a guide...
If you have a friend hold it securely, he can roll it as you cut..
You'll get a fairly nice cut - depending on your eye...
Speaking of eyes - WEAR SAFETY GLASSES!
Deburr it with a smooth file & you're good to go.

I was thinking of doing the same sort of thing, only with my angle grinder (worked beautifully on the flex pipe up top). My big concern was whether it's permissible to cut it off behind that lip thingy.

Just look at that Fireview waiting there.

the lip is not doing you any good if it is 2" back and you can only get 1" in the stove. So cut away and get her burning.

Why wouldn't you cut the larger end (female side)...closer to the T? If you cut the smaller end off wouldn't you be left with two female ends?

Generaly stove pipe (also known as smoke pipe) is cut with tin snips. Since you are going to put at least 3 sheetmetal screws (preferably 4) in each joint, the bump out shouldn't matter much right?

 

[apples439]

Angle grinder works very well.

Why wouldn't you cut the larger end (female side)...closer to the T? If you cut the smaller end off wouldn't you be left with two female ends?

-Todd

If you cut the FEMALE end, you will have two MALE ends & no way to put it together correctly.
You want the MALE end of the connector to go into the flue collar & the MALE end of the tee
to go into the FEMALE end of the connector...

 

[apples439]

The T I have has a MALE end pointing towards the stove. Then I've got a short horizontal run with a FEMALE end and a MALE end. The latter fits into the Fireview. If I needed to shorten that run, for example and I cut the MALE end of that horizontal pipe, which dreezon is proposing, I've got two FEMALE ends and no way to fit it to the stove.

-Todd

 

[DAKSY]

No, you don't. If you cut the MALE end you still have a MALE end. The FEMALE end has a "bell" to receive
the MALE end. You can cut the male end all the way to the bell before you get two FEMALE ends...
Not sure why you aren't getting this, but, you're wrong...

 

[dreezon]

I can settle this argument with dispatch. I cut three inches off a little while ago, and shortly thereafter, my Fireview achieved secondary burn. 'Nough said? ; )

Really it is confusing, though, only because with most pipe, the diamater of the whole pipe IS the diameter of the female end. That's the way the nose pipe coming off the tee is. You'd have to crimp it to make it male. But with the extension pipe I got from woodstock, it's just the opposite; the overall pipe is the same dimension is the male end, whereas the female end has, as someone called it a bell (i.e., it widens out.)

Anyway, thanks for the help everyone. The fireview is cranking now, and my house stinks.

 

[crazy_dan]

enjoy the smell it will go away soon.

 

[dreezon]

I guess I should think of it as "that new stove smell."

 

[Todd]

Congrats, looks great. Let us know how the new stove works out for you.

 

[apples439]

Wow! It turned out great.

Looks like the Dog is saying stay away from my fire.

 

[dreezon]

Thanks for the kind words. I'll definitely post some updates and additional photos as I get to know the stove better. Can't believe a small part of me is looking forward to January ; )
