Robertshaw 700-406 Gas Valve

The Robertshaw 700-406 Gas Valve is a high-capacity 24V standing pilot gas valve engineered for professional HVAC contractors and industrial boiler technicians. This uni-kit gas valve arrives factory-set at 3.5" WC for natural gas systems but includes a regulator cover plate for simple conversion to LP propane applications. With a massive 300,000 BTU capacity and 3/4" NPT inlet and outlet ports, it serves as a robust HVAC replacement part for a wide range of furnace and commercial heating equipment. Built with a standard thermocouple-operated safety magnet and NEMA terminals, this model offers multi-positional mounting, though it must not be installed upside down. It features a manual gas cock with clear Off-Pilot-On positions, a 1/4" tubing pilot outlet, and an inlet filtered screen to protect internal components from debris. This Robertshaw 7000BER model directly replaces the 700-408, providing a reliable 24V furnace gas valve solution for field repairs.

• Universal Compatibility: The Uni-Kit design is suitable for Natural and LP gas conversion, allowing for streamlined truck stock.
• High Capacity Output: Rated for up to 300,000 BTU, making it ideal for large residential units and commercial boilers.
• Flexible Installation: Features 3/4" pipe size with multiple reducer bushings often included for 1/2" adaptor needs, and a compact footprint for tight furnace cabinets.
• Enhanced Safety: Includes an integrated automatic pilot safety valve that performs a complete gas shutoff in the event of pilot outage.

How do I convert the Robertshaw 700-406 from natural gas to LP?
To transition to Liquid Propane, use the included regulator cover plate. You must remove the natural gas pressure regulator and install the cover plate as specified in the technical manual for non-regulated LP applications.

What type of ignition system is this valve compatible with?
This is a standing pilot gas valve specifically designed to work with a 30 millivolt thermocouple. It is not intended for use with intermittent pilot or direct spark ignition systems.

Can this valve be mounted in any orientation?
This valve supports multi-positional mounting. However, it should never be mounted upside down as this can interfere with the internal safety magnet and regulator performance.
