OK to cut 3 inches off extension pipe?

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?

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?

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.

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.

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

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 ; )
