Hi guys and Gals, posting this for my best friend,they bought the stove 1 year ago,warranty runs out in one week.They are pretty dissapointed in the dirtyness of the Glass in just 1 hour of running.They have had no luck at all with the Dealer/tech,he has been to the house a couple times doing a pasper check for air leaks ect,and said everything is as its supposed to be.I myself being an Enviro owner,feel it is a bit excessive for soot,we are both burning same pellets 100% softwood,the pics below of there stove is after 1/4 bag or approx 5 hours runtime,always smokes in same area and is extremely noticable after 1 hour runtime.This is 1 weeks worth of soot on my Enviro EF-III,is there something that needs adjusted here that they are missing?Stove was installed by Dealer.
