Robertshaw Gas Valve Millivolt 700K BTU 710-502

The Robertshaw 710-502 is a millivolt gas valve rated for high capacity applications.

Millivolt gas valves are found across a wider range of equipment than is sometimes appreciated: unit heaters in workshops and warehouses, gas fireplaces and log sets, pool and spa heaters, commercial cooking equipment, and older boilers and furnaces.

Their persistence in these applications reflects the absence of any requirement for electrical supply, along with a simplicity that makes them reliable over long service lives. A well maintained millivolt system can operate for decades.

The maintenance that keeps it working is largely about the pilot. A standing pilot burns continuously, and over years its orifice accumulates deposits, spiders and insects nest in the pilot tube, and the burner itself corrodes. Each of these reduces the pilot flame, and a reduced pilot flame means reduced thermopile output and a system that becomes progressively less reliable.

Cleaning the pilot assembly and verifying the flame properly envelops the thermopile is therefore the central maintenance task, and it addresses the majority of millivolt system faults.

Confirm gas type, connection sizes, and capacity against the appliance, and leak test every joint before returning to service.

Applications include unit heaters, fireplaces, pool heaters, and commercial millivolt appliances.
