If I recall that tank is probably close to 18" in diameter, I've always used a rule of thumb that my exhaust won't exceed the tank diameter in length.
Using that rule you should have a 3.5" pipe at 18" long, my guess is that your chimney may be to long and narrow to promote the temps that your looking for.
Don't forget the gases will cool as they rise and cool exhaust will restrict the flow.
