Jefferson Direct Vent/ Natural Vent Stove Dimensions
Attention
The Jefferson stove is shipped from the factory as a Direct Vent Gas Heater. This heater may be converted
into a Natural Vent unit in the field. If a Natural Vent heater is desired, the Vermont Castings Z31D00
FSDHAG Draft Hood must be directly installed to the top of the unit according to the installation
instructions. The Draft Hood Adapter is available in the 7FSKHASK stove kit or as a separate item.
When the Jefferson stove is converted to Natural Vent, it uses 4” vent pipe. For aesthetic purposes the CFM
direct vent system may be used up to the ceiling.
