Suitable for Gas, electric and ceramic stovetops. Not suitable for induction. 4 cup capacity 20 cm H x 10.5 cm W How to Brew Fill the base with water to just below the level of the safety valve. Be careful not to overfill as the air in the space between the water and the coffee filter is what heats and forces the water up through the coffee. If the water tank is overfilled the result is boiled coffee, with a bitter or burnt taste. Insert the funnel. Loosely fill the funnel with espresso ground coffee, do not tamp. Screw the top section firmly to the base. Place the coffeemaker on a low to medium heat. When using on gas adjust the flame so that it does not extend up the side of the pot. It takes only 3 - 6 minutes, depending on the size of the coffeemaker and the intensity of heat, until its ready to serve. Remove immediately from the heat once coffee pot is full. DO not allow to boil and do not put on full heat as this may cause the coffee to have a burnt taste. Disassemble and hand wash in warm water. Suitable for use on gas, electric and ceramic stovetops, not suitable for induction.
