Robertshaw 720-474 Gas Valve LP Kit

The Robertshaw 720-474 is a 24V AC gas valve designed for heating systems using liquid propane or natural gas. It includes a factory-supplied LP conversion kit and an integrated pressure regulator for versatile installation. The valve supports a maximum heating capacity of 150,000 BtuH and operates up to 175 degrees F.

Verify voltage and gas type before ordering

Confirm your system runs on 24V AC power and uses either liquid propane or natural gas as the fuel source. Check that the 1/2 inch port connection and 1/4 inch pilot port match your existing piping. Ensure the operating temperature range of -40 to 175 degrees F suits the installation environment.

Replaces step-opening valves in 710 series

This unit replaces compatible step-opening gas valves in the manufacturer 710 series where an LP conversion kit and regulator are required. The jump is worth it when the existing valve lacks integrated regulation or cannot handle the 150,000 BtuH capacity needed for the application.

Questions about this item

What comes in the box and what else do I need to buy?

The kit includes the gas valve, an LP conversion kit and a pressure regulator. You will need to supply the 24 V AC power source and the 1/2 in and 1/4 in piping for the connections.

Which version or capacity should I choose for my furnace?

The 720-474 model handles up to 150,000 BtuH and operates from -40 °F to 175 °F, so select it when your appliance falls within that heating range and temperature envelope.

What does the 175 °F rating mean once the valve is installed?

It is the maximum operating temperature the valve can withstand in service; the unit will function reliably up to that limit and down to -40 °F.
