High-pressure regulators are designed for applications where the propane tank is located far from the appliance, while low-pressure regulators are designed for applications where the tank is located close to the appliance.
- Regulator Size: The size of the regulator is critical in ensuring proper operation of the appliance. A regulator that is too small may not be able to supply enough gas, while a regulator that is too big can lead to wasted energy and reduced appliance performance.
Regulator Sizing Charts
Regulator sizing charts can be a useful tool in determining the correct regulator size for a particular application. These charts typically include information on the appliance’s BTU rating, the regulator’s flow rate, and the regulator’s pressure rating.
| Appliance BTU Rating | Regulator Flow Rate | Regulator Pressure Rating |
|---|---|---|
| 10,000-20,000 BTU | 1-2 CFH | 10-20 PSI |
| 20,000-30,000 BTU | 2-3 CFH | 20-30 PSI |
| 30,000-40,000 BTU | 3-4 CFH | 30-40 PSI |
