This will one or more things (1). You will need a manometer to check the gas pressure be sure it is at 11 inches of water collom. (27 inches in 1 PSI) at the back of the gas valve. (2) make sure you have good water flow. If you have an external by-pass this should be 80-90% closed. In the water manifold you will have an internal by-pass assembly this fine tunes the water you control with the external valve. (3) make sure you don't have any derbs around the base of the heater that will block air flow. Also be sure that your heater is away from any wall or has a draft hood.
Any one or more of these things will cause sooting. When you find the culpret and fix then you will need to clean and desoot the heater. Also to avoide this in the future you should have the heater serviced every year before you put it into service.
If you do this yourself be sure to use a plastic brush and not a wire brush as any little spark with the soot can cause an explosion.
This might be one you want to get a repairman involved with and be sure he or she is a profesional.

You didn't indicate your exact model. There are different versions of the H200 series. If it is milivolt then there is no electric, Must have correct milli-volt pilot generator. If it's electronic, check the air flow pressure switch on the combustion air.

Black soot like smoke coming out of top of pool heater,

Your flames should be blue; orange means a poor combustion mixture. Pull the copper jets out of the manifold one at a time and inspect the inside for spider nests. They are screwed into the black tube that exits your gas valve, bends down and then along the front of the burner tubes. You will likely find most of the jets blocked. If they are not or you still have a problem after cleaning them out, you'll need a tech to measure the gas pressure in and out of the gas valve.
