Robertshaw 720-051 Gas Valve

The Robertshaw 720-051 Gas Valve is a 24V HSI Uni-Kit designed for versatile performance in Hot Surface Ignition (HSI) applications. Featuring a 1/2" inlet and 3/4" outlet, this dual automatic gas valve serves as a reliable replacement for a wide range of OEM furnace controls. With a compact 3-9/16" swing radius, it fits easily into tight furnace cabinets where space is a premium. The unit is factory-set for Natural Gas at 3.5" W.C. but includes an LP conversion kit for field adaptability. This intermittent pilot ignition valve handles up to 150,000 BTU, making it suitable for central heating, boilers, and mobile home furnaces. The terminal block features standard 1/4" quick-connects for straightforward wiring, while the multi-position mounting capability allows installation in any orientation except upside down. For technicians, the built-in inlet filtered screen and NEMA standard terminals provide the durability and ease of service required for high-demand diagnostic and repair environments.

• High Capacity Hardware: Rated for up to 150,000 BTU, covering typical residential and light commercial heating loads.
• Universal Compatibility: The 7200DER series replaces various Honeywell and White-Rodgers models using the included reducer bushings.
• Flexible Mounting: Multi-position design allows for horizontal, vertical, or angled installation to match existing manifold configurations.
• Durable Construction: Features an inlet filtered screen to protect the main valve seat from pipe scale and debris.

Is this valve compatible with Standing Pilot systems?
No, the 720-051 is specifically engineered for Hot Surface Ignition (HSI) or Intermittent Pilot systems. It does not have a pilot gas outlet for constant pilot applications.

Can I use this for Propane (LP) applications?
Yes, while configured for Natural Gas out of the box, the Uni-Kit includes a regulator conversion kit for propane use.

What should I use for thread sealant during installation?
Use a gas-rated pipe thread compound on the male threads only. Avoid Teflon tape, as shredded remnants can migrate into the valve and cause seat failure.
