For reliability, performance, flexibility and ease of installation and service in one compact control, Robertshaw's 24 volt combination gas valves are the answer. These valves feature a manual valve (gas cock), an automatic pilot safety valve, inlet/outlet screens, pilot outlet, pilot gas filter and pilot adjustment key. Regulated and nonregulated models are available. The automatic pilot safety valve is separate from the gas cock and provides gas shutoff in case of pilot outage. Valves can be mounted in any position except upside down. The 700 Series 24 Volt Uni-Kits® have a pressure regulator installed that is set for natural gas (3.5" W.C.). To convert to L.P. gas, a regulator cover plate is included, or use 1751-003 to convert valves from L.P. Gas to Natural. Use 1751-013 to convert valves from Natural Gas to L.P. Models have a slotted safety magnet for use with ECO.Made in the USA.
