Not at all uncommon. New heaters have to glaze over the file tile in the burner chamber and will often smoke and smell during the first week or so of operation.
Using a mirror, check to see that your flames are about 4" proud of the burner tubes when running. As long as they are and the color is a nice blue with little to no yellow/orange color, the heater is fine.

It is probably not sensing flame. You either have a clogged orifice underneath the flame sensor and you probably need to have the gas pressure assessed, meter size and gas valve pressure adjustment. These heaters need 2" wc of gas pressure.

Try resetting it by turning off the breaker that supplies power to the heater. This should be located in the power box at the pool equipment. It is probably a 15 amp breaker.
