In our previous house we had a Godin wood burner installed by Godin. They took great pains to explain how important it is to have the burner flue pipe located well away from any old house beams, even inside the chimney. The pipe will get far hotter than an open chimney flue and can ignite a wood beam.
You may want to have someone come in to check your installation is all ticketty boo before next winter but I’m glad you have been so lucky.
