It's easy to turn the 90.000 and 105,000 stoves into a mini furnace.
Air can be directed into another room with the addition of a 6" or 8" vent opening on top of stove. Blower CFM's can be increased from 265 to 350 on 90,000;
from 350 to 500 on 105,000.

Direct Vent
A cost saving benefit for homes without chimneys is Keystoker's direct vent models. A small vent through an exterior wall is sufficient to exhaust combustion gases produced by the stove.
