Is it possible to convert a gas heater to propane?

Evaluating the Existing System

When considering a propane conversion, the first step is to assess the existing gas heater’s design and components. Look for the following: a compatible burner orifice size, a suitable regulator, and a gas type label indicating natural gas or propane compatibility. Check the manual or manufacturer’s website for any specific guidelines or recommendations for propane conversion.

Propane Conversion Requirements

To convert a gas heater to propane, you may need to replace the burner orifice, install a new regulator, and possibly modify the gas line. The orifice size will depend on the propane’s BTU content, with a typical orifice size of 0.040-0.050 inches for propane. A propane regulator typically has a higher outlet pressure rating than a natural gas regulator, usually around 10-11 inches of water column. Consider using a propane-specific regulator and check the manufacturer’s specifications for any specific requirements.

Safety Precautions

When performing a propane conversion, ensure you follow strict safety guidelines to avoid accidents and injuries. This includes disconnecting the gas supply, using approved tools and materials, and following local regulations and codes. It’s also essential to have a working knowledge of gas systems and safety procedures or seek professional assistance if you’re unsure about any aspect of the conversion process.
