Rational iCombi Classic 6-1/1 Gas Combination Oven

The Rational iCombi Classic is a gas-fired combination oven offering steam, convection and combined steam-convection cooking across six full-size (1/1 GN) shelf positions. It sits within Rational's established iCombi Classic platform — a line designed to bring reliable, consistent performance to kitchens that want the core benefits of combination cooking without unnecessary complexity. The unit can be configured for natural gas or LPG supply, which gives flexibility for sites where electric capacity is limited or where gas running costs are a consideration.

In a busy kitchen environment, combination ovens earn their place through consistency and throughput. The iCombi Classic manages humidity within the cooking chamber through Rational's ClimaPlus system, which allows operators to set moisture levels in 10% increments. This level of control is particularly useful when running mixed loads or moving between cooking tasks during a service — roasting and then regenerating, for example — without the inconsistency that comes with less controllable equipment. Multiple fan wheels distribute heat evenly across all six levels, which reduces the need to rotate trays mid-cook and supports reliable results even under sustained pressure.

From an operational standpoint, the key practical advantages are:

• Up to 100 programmable cooking profiles, each supporting up to 12 sequential steps, which supports kitchen consistency across different staff skill levels
• Intuitive dial-and-push interface with colour display, reducing training time and the risk of operator error during a busy service
• Automatic cleaning programme, including an overnight cycle, using phosphate-free tablets — straightforward end-of-day maintenance without extensive manual effort
• Integrated descaling as part of the care system, which is worth noting in areas with hard water supplies
• High-intensity LED chamber lighting, making it easy to assess food colour and doneness without opening the door

Installation requires a gas supply (natural gas or LPG — confirm which at point of order), appropriate ventilation or canopy extraction above the unit, and a suitable drainage connection for condensate. As with all combination ovens, ventilation planning is important — the unit produces steam during operation and adequate extraction is essential for both compliance and kitchen comfort. The unit will also require a water supply for steam generation. For sites without an existing water softener, fitting one is advisable to protect the steam system and reduce maintenance frequency. Confirm floor loadings and access routes before delivery on tighter sites.

The six-rack, 1/1 GN format is well suited to small-to-medium operations — hotel restaurants, school kitchens, care homes, pub kitchens, and similar sites running a moderate number of covers. It handles both production cooking and à la carte service comfortably at this scale. For higher-volume operations or kitchens running multiple sittings, a larger-capacity model from the same platform is worth considering. For very small operations where a six-rack unit would represent excess capacity, a smaller configuration is also available within the range.
