Emergency services - including eight fire engines - were called to the landmark building in Marine Parade at around 7pm on Saturday.
All roads around the building were sealed off as worried onlookers watched the drama unfold.
The boiler room was located on the 13th floor of the building and all staff and guests had to be evacuated as teams wearing breathing gear tackled the flames.
It was quickly brought under control.
Kent Fire and Rescue Service teams believe it was started as a result of an electrical fault.
Crews used a large ventilation fan to clear smoke from the 12th and 13th floors. There were no reported injuries.
Fire teams left the scene just before 9pm.
