Can I vent a small freestanding stove from Vermont Castings that was made to be
Vent free? I want to install a cast iron boot to connect to a Homesaver lined masonry
Chimney. The unit is new and made for LP.

If the unit was designed to be vent free I doupt if you will be able to vent it correctly since the byproducts of combustion are mixed with the heated air the unit produces. So if you did get a way to vent the unit all the heat produced would go up the vent and to the outside.

Most if not all of these units have a oxygen depletion sensor as a safety device to prevent CO poisoning but they can and do fail from time to time. I do not trust vent free heaters unless they are electric of course since the electric heaters do not need venting.

The vent free stove I'm installing will only be used for decoration or providing a little
Ambiance. Never intended to heat the room

The exact usage was never mentioned in your first post. My advice still holds and the unit should be installed exactly as instructed in the owner/install manual that came with the unit. Enjoy.

Why are you wanting to vent it?

I think it it releases too much moisture into the
Home. Even if I just turn it on occasionally, having anything burning in a living area without some venting is against my old fashion
Working knowledge. I know the current trend of the trade tend to accept vent free gas units in the home, but the acceptance is not universal by a long shot.

The owners manual usually instruct you to open a window to help with the moisture problem and also to dilute the combustion by products. I know exactly what you are saying that is why they are not allowed by code in this area. All units must be of the vent type and go outside to a appropriate location as per the listing of the unit. UL/CSA.

Thank you for your input. It seems we are on
The same page as about how this unit can work
This unit was a fantastic
Deal and for that reason I don't mind to even
Changing out the burner part, that will make it
A full vented unit. I have some valves and extra burner pan laying around.
Thank You again

I wouldn't get to involved in converting a ventless to a direct vent. I would suggest selling the ventless as is, and buying a direct vent fireplace. If you got a great deal on the ventless, you should be able to make some money on it to put toward a direct vent.

Just a note,, ventless are not allowed in my state either, there is a reason for it, they are dangerous, a health hazard if ever there was one.

Just my opinion(and a justifiable one at that.).
