VITODENS 200

Troubleshooting Guide

This guide is for internal use only and is NOT a substitute for the technical support literature supplied with the Vitodens 200 boiler and the

accessories. Use in conjunction with Vitodens 200 Quick Start-up Guide and Start-up/Service Instructions.

Before getting started, remember…

• All Vitodens 200 boilers have passed rigorous functionality testing and come factory-tested for proper

operation.

Approximately 85% of all field issues are associated with items external to the boiler, such as:

• Air in the water system (at start-up, air must be purged completely for at least 1 hour)

• Wrong programming (coding) match to connected system

• Air in the gas line (specifically for LP)

• Wrong pump designation, coding or assignment

• Power supply issues (reversed polarity, improper grounding, Ground Fault Interrupted supply, or

unstable power supply).

• Off-grid power supply such as generators, battery back-up.

• Only a few measurements without burner calibrations need to be performed on the boiler. The following are

items that do require measurements:

• Inlet gas pressure (static and running)

• Combustion flue gases and air intake (for direct vent systems)

• Power supply

• Certain fuses

• When changing the coding addresses the boiler must be restarted (power ON/OFF) at least once for the

changes to take effect. The control needs between 2 and 60 seconds to process and transfer data.

• From our own experience, we have replaced the following components on the boilers in the following order:

• VR20 circuit board

• LGM burner control unit

• Fan assemblies

• Complete burner assembly (some due to damage of the inlet air damper)

• When troubleshooting the Vitodens 200 avoid jumping to the premature conclusion that parts such as

VR20, LGM etc., or the boiler are defective. It is important to avoid this assumption.

Troubleshooting Steps When the Customer Calls

Step 1 Collect pertinent information. Please use the Vitodens Diagnostics sheets if possible. A copy is attached

at the end of this document for convenience.

Record the boiler model number, gas type, venting type, system layout connected to boiler, accessory and

equipment used (Low-Loss Header (LLH), mixing valves, etc).
