I bought a Lopi Revere in October and i am pleased with the heat it puts out and how much wood it uses. I have used half the wood so far than last. Except for the back air tube comming off it has had no problems untill recently. I get up a couple times a night and throw more wood on the fire but here lately when i get up the blower has been off. Two hour intervals 2:00 4:00 6:00am. the only thing i can come up with is that there is to much ash/ambers filling up my small burning area. When i do clean it out it burns hotter and it seems longer. Is this right? I need some feed back on what the problem could be. thanks
