Changing the heater to operate on one gas type from another requires:
1) Changing the Injectors (Burner Orifices); and
2) Setting the outlet pressure at the control valve to the appropriate pressure.
You may purchase Injectors (Burner Orifices) from our webstore at https://besthot.store/BH8080016/ (Select the appropriate gas type for the actual gas type on which the heater will be operated.

Using a manometer, you will also need to adjust the gas outlet pressure at the regulator portion of the control valve in the heater's control bracket to either:
- Natural Gas = 5.0 inches of water column pressure; or
- Propane = 10.0 inches of water column pressure
