Water Heater CO2

Is it a good idea to vent my gas water heater into my grow room. My room is vented out side and it seems like a waste of good co2 that my plants would love.

If the distance isn't too great than the added co2 will only help. If it is a long pull, air exchange will decrease unless more fans are added.
