Safety instructions Safety instructions Please follow these safety instructions closely to prevent accidents and material losses. Safety instructions explained Danger This symbol warns against the risk of injury. ! Please note This symbol warns against the risk of material losses and environmental pollution. Note Details identified by the word "Note" contain additional information. Target group These instructions are exclusively intended for qualified contractors.
Safety instructions Safety instructions (cont.) If you smell flue gas Danger The simultaneous operation of the boiler and appliances that extract air to the outside can result in life threatening poisoning due to reverse flow of the flue gas. Fit an interlock circuit or take suitable steps to ensure a sufficient supply of combustion air. Danger Flue gas can lead to life threatening poisoning. ■ Shut down the heating system. ■ Ventilate the installation site. ■ Close all doors in the living space.
Safety instructions Safety instructions (cont.) Repair work ! Please note Repairing components that fulfil a safety function can compromise the safe operation of the system. Faulty components must be replaced with original Viessmann spare parts. Auxiliary components, spare and wearing parts Please note Spare and wearing parts that have not been tested together with the system can compromise its function.
