[old] morso 2b flue size and other questions

[therabbithole]

Having just bought a used morso 2b - in what looks like really good shape - I'm looking for advice on the flue size. The collar measures about 4 3/4" ID, which I assume would more or less accept the crimp on 5" pipe. Does that sound right?

Assuming the stove was originally made for 5" stovepipe, what are the pros and cons of hooking it into a 6" chimney? There's no chimney at all yet, and while 5" would be cheaper it seems like 6" would leave more flexibility for other stoves in the future.

As context, I don't know how old the stove is but the door doesn't have a window like what's on the new model, the air vent is on the bottom of the door rather than the top, and there's no firebrick inside. I found a few pictures of similar-looking models online but without much clear sense of age. Are there any ideas about when this could have been made, and any sense of whether any of the currently available replacement parts would fit? I need a hinge pin, for starters, and wouldn't mind getting a door with a window and gasket groove in it...

Thanks in advance for any help.

Welcome. That's a very nice little stove. I wouldn't hesitate to hook it up to a 6" flue. Our Jotul 602 came with a 5" to 6" increaser just for this purpose. Your reasoning is correct. It makes more sense to install a 6" chimney.

The stove should have burn plates on the sides instead of firebrick. For parts, enter your make and model at this site or work with your local Morso dealer.

Thanks! That's really helpful.
[I'll post separately about the burn plates under a more appropriate heading.]

You're welcome. No need for a new thread if you have questions about the burn plates. The title is all inclusive.
