Most draft inducers need to be placed a minimum of 12" away from the stove outlet. The ideal location is 24" from the stove outlet. The motor also has to be mounted down to keep it from over heating.
Also, depending on your inducer it'd be in your best interest to move the adjustable switch off of the unit. The Tjuerland (sp?) switch is all plastic and will melt if not away from the pipe. They can also be adjusted beyond what the factory has them set at, but you'd need to take the switch apart to find the adjustment pot.
On my hand fed I've got it about 15" away from the stove and just before the 90* elbow into the chimney.
