Four gas burners, series 70. The series 70 is the most widespread because most stores choose to use work benches or refrigerators with a depth of seventy centimeters. The horizontal distance between the burners is 40 cm and the vertical is 30 cm, allowing the use of large utensils on half the burners simultaneously with smaller ones on the remaining burners.

Depending on the needs of each kitchen, the appropriate device is selected. Three different heights have been designed to meet all needs:

• GL Models: Low models, suitable for countertop use.
• GM Models: Medium models, adapted to the height of other devices.
• GH Models: High models, built according to the height of the workbench.

It is desirable that the operating height of all devices be 86-90 cm.
