Monthly Maintenance

The Deluxe Food Warmer utilizes an open steam gen-
erator. Water sprayed onto the generator surface flash-
es into steam immediately, but the minerals in the water
do not steam. They stay on the generator surface. A
small amount of calcium/mineral deposits are need-
ed for proper operation, but a build-up of excessive
calcium/mineral deposits causes poor steaming efficien-
cy, excessive moisture (wet steam), and will eventually
severely retard the steaming action completely.
