Help adding a Fan driven Smoke unit to Burning Switch tower

Some pictures would be a lot more helpful.

I know I can get it into the unit I just don't know how I would mount it.

There are many ways to mount it, but we'd have to know what we're dealing with as far as the interior.  I have put many fan driven smoke units in a variety of locomotives, but each new model is potentially a new experience.

Mount it with the bowl level

Make sure filling it is easy.

Close enough=PITA over time.

"Stand-off's are the name of the "spacer" or "legs" you see for mounting electronics. From locking tab nylon, to threaded brass or aluminum. Wide choice of how to deal with those.

I'd think some O fan units might push "too much air" for a tower's stack? (or is it a Ranger post on fire?)  Balancing fan speed and heat may be part of this too unless you have "that unit" already.

    I keep reading about smoke units that shut off if run dry. Can they be stand alones?  We look at locomotives stack way more, and a dry fluid well = a burn heat resistor, all too soon. For constant static display, I'd look into those that auto detect, or post war ceramics that don't burn out if used dry, and add a mirco10x10mm fan blowing on the vent if needed 

I think the static fan pieces used expansion chambers to even out and slow the flow? I know the hotbox cars did.

 I recently found a few mini-silicone pillboxes my father used. I tested for heat resistance with solder, then flame, and finally stuck a PW element into one.

 In the lid's side, I sliced two small, opposing wire slits, and punched two holes in the top. A bronze flange bushing, and insulating fiber washer, to buffer the bushing from the element, and sits in a bed of the hard to burn strand of a tiki wick stuffed in the bottom. I snapped its lid shut and grinned.

   Why "just to see".   So far, so good. No leaky seal, and holds a good amount of fluid.   No fan, just draft smoking in a cheap little METAL 0-4-0. Four-five 1 hour sessions at 13v, no signs of heat stress so far.

   A set screw would be nice, but it "hammock hangs" ok. The stack liner is propped up, and somewhat askew, but still held firmly  by the wires tension alone (no rattling about). Super light and about the size of $1.50 in quarters.

Careful experimenting with smoke units, could be double the fun.

Edit=metal

I put a fan driven smoke unit from a PS-1 diesel in my tinplate brewery I built. It has it's own power source set at 5 volts just enough for a nice flow of smoke but not blowing out like a cannon. 

I modulate the speed of the fan and the heat to the smoke resistor to adjust the quantity and flow of the smoke for stationary use.

Why not existing screws into threaded standoffs (mounting posts) as apparently used in the Diner cars as shown in photo taken from following:
