So I'll start with my conclusion...it appears that Selkirk does not make a stove adapter and/or pipe connector to fit the Harman PF100.
The OD of my flue collar is 4 3/16. Their standard connector (4vp-pc) is too small. They make an adjustable one (4vp-apc) but it is really intended for sizes up to 4 1/16. By the time had it bent open enough to fit over my flue, it would've taken a whole tube of RTV to seal it up. Not my idea of a clean install. I called Selkirk...they said "Well, what does Harman reccommend?". I called my dealer - they use ICC Exel for their installs. I called Harman...they said "How did you get this number?" Seriously (I apparently called the direct-line of somebody important)...but I will never tell. Then he confessed that their flue collar sizing was based on Simpson DuraVent. Would have been nice to know that ahead of time! I know many guys on here use the Selkir pipe with their Harman stoves...I can only assume the flue collar varies by model. Maybe the 3" is different...I dunno?
I have been trying to install this sucker for a month. Took me 3 weeks to get the adjustable collar, only to find it didn't adjust nearly enough.
My new solution is to use a 6" piece of pipe (4vp-6). The flue collar fits nicely inbetween the stainless liner and the galvanized outer shell. The Selkirk pipe has a ring of that high-temp insulating rope-looking stuff. I'm going to trim 1/2" off the outside galvanized part (my collar is 1.25" and the pipe has a 1.5" overlap) and apply a bead of RTV to the insulating stuff and side it down on there.
Holy Cow...this has been the most frustrating part of this deal. One would think if their flue collar isn't compatible with a major product line that they would make that known...
