How to Tell if Your Valor Heater is Gas or Propane: A Comprehensive Guide

Determining whether your Valor heater is running on gas or propane is crucial for ensuring its safe and efficient operation. This comprehensive guide will walk you through the step-by-step process of identifying the fuel source and inspecting the burner flame to help you make an accurate assessment.

Checking the Fuel Source

Fuel Line Inspection: Examine the fuel line that connects to your Valor heater. Gas lines are typically made of black iron pipes, while propane lines are usually made of copper or rubber hoses. However, it’s important to note that some newer gas lines may also be made of copper or rubber, so this visual inspection alone may not be conclusive.
Fuel Line Diameter: Gas lines for Valor heaters typically have a diameter of 1/2 inch, while propane lines are usually 3/8 inch in diameter. Measuring the fuel line’s diameter can provide a more definitive indication of the fuel type.
Fuel Line Pressure: Gas lines for Valor heaters operate at a pressure of 7 inches of water column (WC), while propane lines have a pressure of 11 inches WC. Using a manometer or a pressure gauge, you can measure the fuel line pressure to determine the fuel type.
Fuel Line Connections: Gas lines for Valor heaters often have threaded connections, while propane lines may have flared or compression fittings. Inspecting the type of connections can also help identify the fuel source.

Inspecting the Burner Flame

Flame Color: Turn on your Valor heater and observe the burner flame. Gas flames are typically blue with a small yellow tip, while propane flames are often blue with a larger yellow tip. If the flame is mostly yellow or orange, it may indicate an issue with the fuel-air mixture or a problem with the burner.
Flame Height: Gas flames for Valor heaters generally have a shorter, more compact flame compared to propane flames, which tend to be taller and more diffuse.
Flame Stability: Gas flames for Valor heaters are typically more stable and consistent, while propane flames may exhibit more flickering or uneven burning patterns.
Flame Noise: Gas flames for Valor heaters often produce a quieter, more subtle hissing sound, while propane flames may generate a louder, more pronounced roaring noise.

Consulting the Manufacturer

Model Number: Look up the model number of your Valor heater and consult the user manual or the manufacturer’s website. The model number typically indicates the fuel type, with “G” denoting natural gas and “P” indicating propane.
Manufacturer Specifications: Review the technical specifications provided by Valor Fireplaces for your specific heater model. This information can confirm the fuel type and provide additional details on the heater’s operation and maintenance requirements.
Manufacturer Support: If you’re still unsure about the fuel type or have any other questions or concerns, contact Valor Fireplaces’ customer support team. They can provide expert guidance and assistance to help you accurately identify the fuel source and ensure the safe and proper operation of your Valor heater.

Safety Considerations

Regardless of the fuel type, it’s essential to exercise caution when working with gas-powered appliances. Always turn off the power before attempting any maintenance or inspection, and consider using a gas detector to check for leaks. If you’re not comfortable performing these tasks yourself, it’s best to consult a licensed HVAC technician who can safely and accurately diagnose the fuel type and address any issues with your Valor heater.

Conclusion

Determining whether your Valor heater is running on gas or propane is a crucial step in ensuring its safe and efficient operation. By following the detailed steps outlined in this guide, you can accurately identify the fuel source and inspect the burner flame to make an informed assessment. Remember to always prioritize safety and, if in doubt, consult a professional for assistance.
