PITA factor not very bad. The amazing thing is it fits so PERFECTLY, right out of the box (see images).
Mount the unit with 4 bolts, cut the hole for the chimney, then cut the flex pipe to fit, and the unit is mounted in very short time.
Run 12v from a fuse at the helm. Easy.
The biggest PITA would have to be bringing the propane line from the flying bridge tank. I measured the run very carefully, then had fittings professionally installed on both ends of the propane hose (not expensive, and worth it in safety and aesthetics). You have to remove some interior for this step, and I'm about out of room for wires/hoses coming from upstairs, so that was kind of a hassle.
So you'll know, this model P9000 will not warm the entire boat from scratch at 35 degrees. It will however, keep the boat warm, after the boat has been warmed with engine heat. It's also a real crowd-pleaser to see the fieplace in operation. EVERYBODY comments on it.
I would actually like to also add a vented catalytic heat, like you see on all 26' Tollycrafts, just don't know where I'd put it.
