5.1 Adjacent Systems

Handling exhaust air

During operation, the combi oven will produce heat and moisture, most of which will escape upwards into the ambient air in the form of hot steam coming through the air vent(s). Do not connect any lines or ducts directly to the combi oven's air vent(s)! The manufacturer recommends removing this exhaust air from the combi oven's working area with a range hood or ventilated ceiling. In order to prevent fire hazards and other structural issues, such as corrosion, mold, and/or a de‐ crease in stability, there must be sufficient clearance between the top of the unit and the ceiling. This clearance must be determined by taking the following into account:

■

The reference point for the minimum vertical clearance (refer to 'Installation Location Require‐ ments' on page 34).

■

The type of exhaust system being used

■

The characteristics of the ceiling at the installation location

The combi oven must always be set up, installed, and operated in compliance with all applicable coun‐ try-specific and local standards and regulations.

Handling exhaust gas from gas units

Exhaust gas with a temperature of up to 930 °F will escape into the ambient air through the exhaust outlet(s) at the top of the unit. Do not connect any lines or ducts directly to the combi oven's exhaust outlet(s) in order to divert this exhaust gas! It is absolutely mandatory to use a ventilation system with a safety shutdown function in order to evac‐ uate the exhaust gas. In order to prevent fire hazards, there must not be any flammable materials above the unit, and there must be sufficient clearance between the top of the unit and the ceiling. This clearance must be deter‐ mined by taking the following into account:

■

The reference point for the minimum vertical clearance, refer to
