A: This blower does come with a thermostat.  it is magnetized and attaches to the underside of your firebox.  The bottom of my firebox was insulated so I had to remove and jumper wire for manual operation.  I'm not familiar with your model so I can't comment about the fit

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect fit!
*by T***. on November 28, 2022*

I installed this in my Napoleon Ascent 42” gas fireplace. For 3 years I struggled with the idea of paying $250 for the Napoleon AUB fan kit. I found these aftermarket kits on Amazon but figured it had to be garbage if it’s only $40. I finally decided I would try the budget kit and I am so glad I did! This kit is great! Easy to install, perfect fit, great flow and not noisy. It arrived well packaged and all parts seemed quality built. I highly recommend this kit!Note: If you are installing this in an Ascent series fireplace, check your outlet box under your fireplace and if it is a 2 prong outlet you will need a 2 prong to 3 prong grounded outlet adapter ($5 here on Amazon).

### ⭐⭐⭐⭐⭐ Works, easy install
*by J***3 on January 28, 2021*

Instructions weren't perfect, but easy enough to figure out once I layed everything out.Works like a charm. Definitely makes some noise when you turn the fan up, but that's airflow and design of the fireplace and not the fan itself.

### ⭐⭐⭐⭐ Replacement for GA3450TA
*by R***D on December 6, 2019*

When using this blower motor, to replace the GA3450TA; this will work. Since the vent is on the bottom; I had to flip it over, which places the motor on the opposite side. This meant that I had to extend a couple of wires, to reach that far. Not complicated; just had to be done. Once completed; the motor worked as expected. A little noisy, but moves the air well.
