John,

We too are looking for an outdoor linear see through propane gas fireplace that has glass on either side completely encasing the viewing part of the unit to prevent todlers "prying hands" from getting too close. This could be either a ventless or direct vent unit as this is a new construction application. Having some heat output would be nice as this is on an upstairs deck (over our 2 car garage) but it is an outdoor application. We are trying to avoid "breaking the bank" with this purchase (Davinci sells a commercial unit for around $20K). "Flare" sells a ventless unit for an outdoor application but I was quoted a price of $17-18K. The problem with the ventless units as I understand it, is that the flames are smaller (most are indoor applications like yours) but they can be good heaters it sounds like. I would also like advice on this purchase. Dave
