researching replacement blowers and found this site and the c550 thread. have to say the 550 was a waste of money. replaced a free standing Vermont Casting (great heat output) that was in front of the fireplace to aesthetically please the now ex-wife. first of all, the fire needs to die to empty the ash. the V Cast had a drawer on the bottom. simple. the blowers on the 550 (when they briefly worked) suck ash that falls out of the box and pumps the ash into the room. bad blower location. poor design. this is why the blowers fail! your blowers WILL FAIL!! jotul will tell you to contact the dealer. my dealer, Preston Trading Post, told me the blowers are only covered for 1 year. bought this over priced cast-iron pile of junk in Oct., was not impressed with the heat output ( been burning for years I know what I'm doing) or the noise of the normally operating blowers. shut it down for the summer and, come Dec. of the next season, the blowers began to squeal then quit! do the math. yes it was over a year since the purchase but only 7 months of actual blower operation. Preston, the dealer, didn't want to hear it. have been running the insert ever since without the blowers. as stated at the beginning of this admitted bloviation, I'm breaking down and pricing after market blowers to please my new wife. tried to tell her the same thing will happen but, whatchya gonna do? spend more money I guess
