A steam generation apparatus is set forth including a housing; a boiler adapted to generate steam within the housing; a filler cap adapted to be removably coupled to the boiler; a first pressure relief device coupled to the boiler adapted to release steam at a first pressure level; and a second pressure relief device coupled to the boiler adapted to release the steam at a second pressure level, where the second pressure level is higher than the first pressure level, the first pressure relief device is incorporated into and is made to vent into the filler cap, and the second pressure relief device is made to vent internally to the housing.
