The gas burner is earth-friendly as it produces less NOx and CO2 greenhouses gases. Indoor models are designed with zero clearance or models with the sealed combustion. This and its unique venting system is what allows them flexible installation inside the home, as long as you follow the recommendation such as the professional installation and the use of original vent kits.

All of the components are high quality and most of them are replaceable. So if something breaks, great design allows an easy replacement.

They are also smart since the built-in diagnostic system shows the error codes which helps in troubleshooting.
