Hello, new to all things pellet here. I installed this stove yesterday in a mobile home. Noticed after the 3 or 4 hour mark (heat and blower settings at factory recommended 5) there was very lukewarm air coming out still. Flame was perfect, blower working, everything seemed to be working. As far as venting I have it in a corner with a 45 elbow out of it, through the wall and 4' of rise outside. OAK is installed as well. One other note, I let it burn through the night and by early morning there was no flame, but some unburned pellets and a PILE of ash. Not sure if this might be a venting issue? I live in Eastern Montana. Night time temps in mid 20's, elevation about 3000. I appreciate any help for this guy about to freeze in a couple nights!
