Does anyone have a wall gas furnace?

[DCDiva]

The furnace was removed before we bought the mh--we removed the vents--worthless--when we replaced the floor---we heated w a vent less stove,wo insulation in 5 degree weather this winter--600 sq ft to heat--we were toasty---since then we replaced all windows,insulated all,drywall so it will not take much to heat it--the ventless added a lot of moisture--the gas wall furnace is @$390 and direct vent---pros /cons
