REGIONS SUPPLY BUYING GUIDE

Product details & buying advice

When ordering for a paired-cylinder supply, identify the changeover assembly and the connections used by the complete cylinder setup.

Product type Automatic changeover regulators
Part / SKU 5727B34

What to check before ordering

  • Confirm the regulator stages, supply conditions and delivery pressure required by the system.
  • Check capacity for the combined appliance load rather than judging by the port sizes.
  • Verify pigtail connections and the manufacturer’s indicator and changeover procedure with your installer.

Service reminder: Keep cylinder replacement on the service schedule. Automatic changeover does not mean that an empty cylinder can be left unattended indefinitely.

Have gas-system installation and service completed by qualified personnel. Use the current instructions for the exact model and the requirements that apply at the installation location.
