General Information About these Start-up/Service Instructions Take note of all symbols and notations intended to draw attention to potential hazards or important product information. These include ”WARNING”, ”CAUTION”, and ”IMPORTANT”. See below. WARNING Indicates an imminently hazardous situation which, if not avoided, could result in death, serious injury or substantial product/property damage.
General Information Applicability CAUTION The boiler serial number must be provided when ordering replacement parts. Some replacement parts are not reverse compatible with previous versions of the Vitodens 200-W WB2B boiler.
General Information Mechanical Room During the early stages of designing a new home, we recommend that proper consideration be given to constructing a separate mechanical room dedicated to the gas- or oil-fired heating equipment and domestic hot water storage tank(s). The boiler must be located in a heated indoor area, near a floor drain, and as close as possible to a wall. Whenever possible, install the boiler near an outside wall so that it is easy to duct the venting system to the boiler.

To do so, change coding address “6F” in coding level 2. 1. Start up boiler. 2. Press “9“ and “t tw“ simultaneously until a value flashes on the display (e.g.
Initial Start-up and Service Steps (continued) Initial start-up 14. Check coaxial venting system for leaks (circular air gap measurement) A Viessmann strongly recommends that the heating contractor perform a simplified leak test during boiler start-up. For this purpose it is sufficient to measure the CO2 concentration of the combustion air in the coaxial gap of the air intake pipe. The vent pipe is considered sufficiently leak-proof if a CO2 concentration in the combustion air no higher than 0.
