This article provides an overview of troubleshooting gas burners for hot water supply in the David Webster building at WITS.

The building has transitioned to gas burners for increased efficiency, and this video series offers technical maintenance information for the burners.

Key components such as the circulation pump and thermostat are discussed, along with their roles in the system.

Error codes and troubleshooting methods are also explored, emphasizing the importance of regular servicing and maintenance.

By following proper troubleshooting techniques, building occupants can ensure the efficient operation of the gas burners.

Burner Components and Control Logic

The third video in the VITS PMD maintenance technical series focuses on the main components and control logic of the gas burners used to replace electrical geysers for hot water supply in the David Webster building at WITS.

The burner components include a circulation pump and thermostat, which are responsible for maintaining the desired temperature of 60-65 degrees. The pump is activated when the tank temperature falls below the set temperature, and it circulates water from the bottom of the tank through the burners.

The burners themselves are positioned at the top half of the tank, allowing for efficient heating of the 10,000 liter storage tank in just 2 hours.

In terms of maintenance, it is important to have gas consultants or installers available to troubleshoot any issues, especially when encountering error code 10, which is the most common and requires professional attention. Regular servicing and adherence to preventative maintenance schedules are also essential for the proper functioning of the burners.

Circulation Pump and Thermostat

The thermostat is set at a temperature range of 60-65 degrees and is activated when the tank temperature falls below the designated range. This activation triggers the circulation pump, which circulates water from the bottom of the tank through the burners. The purpose of this process is to ensure that the water in the tank is heated to the desired temperature.

To maintain the efficiency and functionality of the gas burners, regular servicing procedures and preventative measures are necessary. Gas Rinnai contractors are responsible for servicing the burners, and maintenance contracts are in place to ensure proper care.

In the event of an error code 10, which is the most common issue, a gas consultant or installer should be contacted for fixing. Following a preventative maintenance schedule and conducting initial checks are important to identify any potential issues and address them promptly.

Temporary solutions like switching off and on the unit may be used, but it is crucial to contact the contractors for proper servicing and repairs.

Heating Capacity and Burner Positioning

Heating capacity and burner positioning are important factors to consider when optimizing the efficiency of the gas burners in the system.

The burners in the David Webster building are capable of heating a 10,000 liter storage tank in 2 hours. This heating capacity ensures that hot water is readily available for the building’s occupants.

Additionally, the burners are positioned at the top half of the tank, which allows for efficient heat distribution. By positioning the burners in this way, the solar energy charged into the bottom half of the tank during the day is effectively utilized.

This strategic positioning minimizes energy consumption and maximizes burner efficiency. Proper burner positioning, along with the heating capacity, plays a crucial role in ensuring an optimal and efficient hot water supply system.

Error Codes and Troubleshooting

Error codes are used to indicate specific problems or malfunctions in the gas burner system, providing valuable information for troubleshooting and addressing issues with venting, exhaust, or blockages.

The most common error code encountered in the gas burner system for hot water supply in the WITS building is error code 10, which is displayed on the unit’s window. This error code typically requires the assistance of a gas consultant or installer for fixing.

Additionally, there are other error codes such as 11, 12, 14, 16, 32, and 72, each indicating internal problems with the gas burner system and having specific meanings. Troubleshooting these error codes is crucial for gas burner maintenance and repair, ensuring the proper functioning of the system and preventing further issues.

Frequently Asked Questions

What are some common error codes that may appear on the gas burner unit’s window?
