New flue on log burner

[Diorinthecountry]

We are getting a new flue put on our log burner tomorrow morning. Will we be able to use our log burner tomorrow night?

I've had a Google and can't find anything.

The people who put mine in lit a fire before they left to make sure it was working properly.

@QuillBill thanks. I can't wait until its fixed and I can use it again.
