Hi, I am new here so if I screw up, go easy on me. I recently purchased a Vermont Castings Merrimac. It seems to be difficult to get a fire started when it has died down to coals. I have used twigs and small kindling, mixed with newspaper. It initially lights ok with the door open but when shut it seems to be starved for air. I would leave it cracked but the smoke rolls out the door and into the house! Is this simply a charachteristic of a large stove, and it simply needs to establish a warming of the air in the liner to establish a draft? Could my draft control be broken or defective? The unit is brand new so nothing should be clogged. I am burning 1yr old red oak, 25ft brick chimney with 6inch steel liner. Once fire is established it seems to have no problems and works excellent heating my 1700sq ft colonial.
