In fact, in Quebec building code, you have to leave 100 cm around the furnace.and i think in Ontario building code, it could have same restriction, in any case, you should leave reasonable room around the furnace to facilitate the maintenance or installation when it is necessary.
keep up the good job and enjoy!
