The Roller Grill GES20 uses 1 cooking grill and is designed for Liège-pattern waffles. Its cast iron plates form the smaller square pattern associated with this waffle style, making it suitable for serving freshly cooked Liège waffles in commercial catering settings.

It cooks two Liège waffles per load. The cast iron cooking plates contain two grids, each arranged as 4 by 6 small squares, so both waffles cook within the same single-machine cycle.

The thermostat adjusts from 0°C to 300°C, with pilot lights supporting operation and temperature monitoring. Heating elements beneath both cooking plates distribute heat across the cooking area, while the insulated handle and counter-balanced upper plate help the operator manage repeated batches.

A useful starting point for Liège waffles is about 220°C for approximately 2½ minutes. Results depend on the dough, so check the first waffle and adjust the thermostat or cooking time as needed without exceeding the machine's 300°C maximum.

Before first use, remove the protective anti-rust coating with detergent, apply food-grade oil to the cast iron plates and season them with the upper plate closed. Re-oil the plates after seasoning and discard the first two waffles used during this preparation process.

A removable four-sided drip tray surrounds the lower cast iron plate to collect excess batter. Once the appliance is disconnected and completely cool, clean its exterior with hot water, washing-up liquid and a soft sponge; do not place the electrical appliance under a water jet.

The Roller Grill GES20 operates from a 230V plug-powered supply. Its electrical rating should be checked against the available supply before use.

The unit weighs 19 kg. Its silver finish, cast iron cooking plates and professional single-waffle-maker format make it a substantial countertop appliance intended for regular commercial use.

It includes a 2-year parts and labour warranty, providing commercial buyers with support for the covered period.

The model reference is GES20, while GD357 is the Smart Hospitality Supplies product or ordering code. These references help distinguish this single Liège waffle maker from other plate patterns and double models in the Roller Grill range.
