I had scrolled through a few older threads on wood-burning stoves, but this topic does not seem to have been addressed.
So the deal is: We are putting in a wood burning stove, and the person doing the installation says that we have to install an air vent from the outside. It's not like this place is airtight (built 1845). We also have an air duct/exhaust above the stove.
I dug around, came up with a few sites, in English:
And in french: http://www.acqualys.fr/page/regles-de-pose-de-grille-d-air-et-conduit-poele-a-bois-et-granules and http://www.bricozone.be/fr/poele-insert-pellets/t-prise-air-exterieur-poele-bois-69809.html and https://www.poelesabois.com/installer-un-poele-et-un-conduit/choix-emplacement-pose-poele-a-bois/arrivee-dair.php and http://www.debusquer.info/chauffage.bois/poele.a.bois.php.
What is the experience of others who have installed a wood burning stove? If you put in a vent, what size was it? Our stove is going to be 8kW. So we might need 50 cm2 (~7.8 sq. in), if this site is correct (https://www.poelesabois.com/installer-un-poele-et-un-conduit/choix-emplacement-pose-poele-a-bois/arrivee-dair.php)
And no, I have no real confidence in the "artisans", less so in that their record of keeping to schedule and showing up on the scheduled days is pretty doggone pathetic.
