Our new stove is driving me nuts! We bought the Hampton GC160 pellet stove less than 1 month ago and cannot get it to heat consistently... Do we need to install the air intake? Our setting is on hi/lo stove is on 5 per the instructions from the professional installer and it's barely 70 in the room the stove is in. Other times at the same setting it's 85! We have already used 1 ton of soft pellets in about a 3 1/2 week time. I have to turn my oil heat to 68 so I do not wake up to a freezing house. I am at the point that I think we may have purchased the wrong stove... I have placed several calls to the installer and they were finally going to install the air intake today in the hopes the stove would work for us but... They forgot to mention we needed to turn the stove off for an hour before they arrived to cool...call me crazy but I did not know this and they would no wait while the stove cooled. Please help as I am so frustrated with this stove and if you have ANY advice it would be much appreciated.
