I want to put a wood stove in my basement. My house has forced hot air with a zone upstairs
And a zone in the basement.

Where I want to put the stove, there is a return duct close by tha
I think I will relocate.

My questions is, is there any risk of carbon monoxide
Going to the return duct, regardless of where it is, making its
Way to the air handler and then getting supplied to the upstairs?

Is the risk mitigated if I turn the downstairs zone off where the
Stove wil be , and close the supplies and block off the return duct?

Thanks
 
The return duct is ok as long as there is no return intake within 10 ft of the stove. A sealed duct is fine. Are there any return grilles in the basement?

That said, basement installs can be tricky due to negative pressure. An imbalanced system with too strong return air draw in the basement can reverse draft. In that case CO would be a symptom and not the cause.
 
Some might say it's a good thing (if it's OK within code) as it might help circulate the heat.
Will you have outside air for the stove?
