Would it be safe to say that since the LL has more components with it's power vent that it would explain the two very different price quotes from each dealer selling the two different brand stoves? On the drawing it shows a draft control unit which allows supplemental air in through it, what part is that in the items list? Is the rheostat to control the Power Vent speed item (b) in the drawing? It says "the burner shuts down and the venter continues to post purge" does that mean the power vent is now not using electricity to vent the exhaust at that point?
Draft control and post purge are for a gas or oil systems, disregard that information. Best bet is read the manual for which ever you are looking at to understand the exact way it will operate, as with all forum advice, you get what you pay for.

There's a piece that connects right inside the exhaust pipe? It says it has a maximum working temperature of 140 degrees, isn't that low for an exhaust pipe? Do the coal stove pipes not get as hot as a wood stove pipe does? The guy at CSM told me that the exhaust on a power vent is low only around a couple hundred degrees, wouldn't that fry at 200 degrees?
The rheostat controls the draft and without a manometer you are operating blind, either sending extra heat out or CO into the house. The connection of the Dwyer is made using a small section of steel tubing inserted into a hold drilled in the stove pipe for situations where the temp is higher than 140*F or in the case of the DV just before the DV unit. I have seen them used on stack temps upwards of 500*F with no issues with this setup. BTW a direct vent must be cleaned every month or it will clog and cause big issues with CO in the house, some folks go longer but take a look at a unit I just recently removed from a DV Keystoker I'm rebuilding.[/quote]

Per Keystoker it can, make sure you check with your dealer to confirm that is true on the model you are buying. Distance from openings and walkways are identical for PV or DV, in fact the Keystoker diagram looks familiar with respect to the Field Controls diagram.
