This combustion blower is the larger of two exhaust blowers used on the Quadra-Fire 1000 Series. Come with a housing mounting gasket. This is a variable-speed motor and the motor is NOT removable with a hub. The Motor must be replaced with housing. The appliance collar that connects to your venting will need to be removed from the old housing and attached to this motor, as that part is now obsolete.
Our picture shows the wire connections as two female AGW 18-22 Bullet connectors, this product actually comes with 1 female bullet and 1 male bullet.
