I am in the process of finishing the install of my Harman XXV. I am using Simpsons pellet vent pro (rated with 1" clearance, I use 3"); the stove dealer sold me the usual high temp silicone that everyone uses to seal the pellet vent. Simpsons says that the vent is engineered so that silicone seal is not required but optional. Harman recommend sealling the connection with a silicone seal. So I sealed every connection with the silicone including at the connection between the simpson vent pipe adapter and the exhaust port of the stove itself. Seems perfectly normal to me. My question is .... Will the heat of the stove and the silicone (rated hight temp) produce a dangerous odor within the house (with very small children)? Can someone please give me some insight. As always, I tank you so much in advance.
