draft inducer fan or support tall pipe

I think a draft inducer TJERNLUND DJ3 or D3 would be better, but might go with pic 1 and 2 if i can tie this up strong against 200mph winds. thoughts?

Have you considered a power venter instead of a draft inducer then you wouldn't have that pipe outside the house. By the way that elbow is compounding your problem. Natural draft comes from an upward pipe or chimney. You are creating no natural draft with that 90 on there.

The sight below will give you some info. Don't worry about the pipe size, it must match your appliance BTU rating. Depending on BTU you may need the 4". Three goes to 70,000 BTU, the 4" up to 170,000.
