If your fireplace blower is making noise or not working right, this GZ550 replacement will get you back in business! This exact replacement fits tons of Napoleon and Continental fireplace models - we're talking B36NTR, B36PTRE, GD36NTR, and dozens more. The specs are solid: 120V, 3000 RPM motor, 110 CFM airflow, and it handles heat up to 392°F with Class H insulation. Measures 9.75x3.73x3.23 inches with 7.13 inch air discharge. Comes with three double-stick foam pads that reduce vibration noise and make installation super simple. Also crosses references with EP62-1, Rotom R7-RB59, R7-RB61 and works with Kozy Heat models too. A fresh blower not only makes your fireplace quieter but also improves heating efficiency for larger rooms. If you're tired of that annoying whirring sound or your current blower just gave up, this direct replacement installs in minutes and gets your fireplace performing like new again. Much cheaper than calling a repair service and way easier than you might think to swap out yourself.
