The confusion relates to what is this door called: is it a Category A door that requires no additional seal to achieve the positive pressure rating, or is it a Category B that requires an additional seal for the door to meet UL10C requirement? My suggestion is to know what all is required of the opening. If you know your single swing 20 minute doors also require smoke seals, then order the doors without built in seals and save money and resources. If the opening does not require a smoke seal and the specification calls for built in seals, then provide doors with built in seals.
