this is the 3rd pellet insert i have purchased 1st two where quadra-fire pellet stoves after a few years the 1st quadra-fire rusted out the burner pot due to use of clean burn pellets ( they contain salt from the puget sound in wahington ) repaired that then electronics went so replaced it with same quadarfires blowers are very loud . moved into new house bought a comfortbilt insert so far very happy with it the ease of operation and the quiet blower motor and really heats up our living room i also installed a 4" flex kit for the chimney very nice installation. I installed the insert without any else's help would like to attach pictures
