All,

I removed the blower from my Lopi Republic 1750 insert this morning. The blower is mounted directly below the 4" metal flange the extends out from the firebox below the door. It basically sits under that flange.

I removed the blower expecting to see the snap disc mounted to the underside of the firebox.

But no, there are no wires going out of the blower unit. It's entirely self-contained.

This means to me that the snap disk has to be inside the blower unit, which is below and in front of the firebox (one of the coolest spots around the stove). My stove sits on slate and I can tell you that the slate will barely warm even after hours of hot burning - the blower sucks cold air along it and the heat simply doesn't radiate downwards.

This explains why my fan usually won't turn on for 30 minutes, sometimes even longer.

Since there's no way I'm going to remount the snap disk on the firebox (not going to tap holes in my beautiful plate steel!), I've decided I'm going to splice the wires straight together and put the fan on a timer so I can set it for overnight.
 
So I meant to ask - does this round right? the snap disk is contained within the blower unit and is not actually mounted against the firebox?

I just looked through Lopi's paperwork on both the overall unit and the blower specifically. I can't see a wiring diagram, so I'm gonna need to do some disassembly here...

BeGreen - No, that's for the freestanding stove blower. My blower attaches under the ashlip and via 2 screws only. As far as I can see, there's no knock-out in the front for the snap disk.

I also, when at home this morning, did not see any 2 wires that went anywhere indicating a snap disk present. There was a small wiring harness, that's about it.

Here's the entirety of the installation instructions for my blower: http://www.lopistoves.com/TravisDocs/17601049.pdf

Page 19 of the lopi republic 1750 insert's owner manual shows the entirety of what they list for blower operation: http://www.lopistoves.com/TravisDocs/100-01234_000.pdf

(note, it says it will typically take 15-30 minutes - my experience has been consistently around the 30 minute mark)
 
I would be very careful experimenting with snap-switch mods. There is a reason for the snap switch to be screwed to a springy metal base. You are dealing with hot surfaces here. Caution should be taken to protect wiring from heat. I would use screws instead of glue to attach the switch. Installed correctly, the factory setup usually works fine.
 
My disc clips onto the back heat shield with the disc touching the back of the stove.It rest between the heat shield and the back of the stove.
