raincap necessary for partial liner installation

[ba_jie]

hi,
Is raincap/plate needed for partial liner installation? If not, how to prevent rain get into stove?

This might be a stupid question. I think rain-cap probably should be required because the chimney damper is removed.

I have a block off plate on my damper. We received several inches of rain about a month ago and not a drop land in my stove.

Why would you not want a rain cap?

The reason i asked the question is that my liner is 3 ft short from the top of the chimney.
So unless i extend it, i can't make the liner meet with the raincap. So it's kind of odd that i install the raincap without a liner attach to it. But now i do think i need the raincap and a block off plate.

One side question, if i install the liner that is 2 or 3 ft away from the raincap, is it still considered as a full liner installation?
I think draft wise, it won't make big difference. The liner is 15 ft long already. The big question is future cleaning. So will there be potential crestor built-up in the chimney because there is still 3 ft of the wall exposed to the smoke.


Thanks and hopfully i made myself clear.

Unless you have a completely airtight blockoff you are going to lose alot of heat, and even with it you'll lose some. You will be putting a lot of creosote at the top of the chimney, too.
Best to have it lined to the top, sealed off airtight w/ rain cap/critter cage/spark arrestor. You could leave as is, but I would extend w/ a section of rigid if possible.
