The most popular range is the standard G series, (shown on the left) suitable for all users who do not need particularly sophisticated and expensive control systems. They are provided with a stainless steel multi gas burner, permanent pilot and piezo- electric ignition.

The GE series (shown on the right) are equipped throughout the range, with electronic ignition. This series therefore represents the advantages of not having a permanent pilot, with resulting fuel savings. The electronic ignition system allows for the use of more sophisticated controls (building energy management systems).
