Blower Kit with Variable Speed and Thermostatic Control

The Napoleon variable speed blower with thermostatic control allows you to push more heat from the stove and cover more space in an efficient manner. The blower simply attaches to the back of the stove and plugs into a standard power outlet. The Blower Kit comes with a Thermostatic Control that will automatically shut off the blower once the stove has cooled down. The blower is a 120 CFM blower and is very quiet. You will not even know it is on when the blower is running.
