2. Direct Vent

With a Direct Vent heating product, economy is increased by using outside air to support combustion. Inside air is warmed as it re-circulates around a sealed combustion chamber, and this warm air heats the room and reduces drafts.Most direct vent fireplaces use a 4" inner and 7" outer flue system requiring a 1" air space all around.

3. Up-Vent (Conventional Venting)

The Conventional Vent version can be vented vertically.
The vent pipes are connected between the firebox and flue to carry
the products of combustion outside. It is perfect for replacing your current woodstove or for installations without access to an outside wall. Typically up-venting is mostly used for wood fireplaces and uses larger flues.
(8"inner and 13" outer appx.)  When installing a wood stove the flue size will run 6" to 10" appx.

Most wood flues require a 2" air space around them.

One characteristic of Conventional Vent heating is that the product uses inside air to support combustion.
