Hello Jean,
Awhile back we installed a woodstove on our W32. We ran the flue/stack into the center of the mast pulpit legs on purpose. This protects the chimney, deck iron, etc from being damaged by lines under tension and also protects us and the lines from being burned.
When using the stove we make sure to move the flag halyards and other lines from the pinrails to cleats elswhere (depends if we are underway or, anchored).
Our stove is located on the Stbd side near the bulkhead. Its likely it would also work for Port side.
Hope this is helpful.
