Product identity
The Value Brand 700-504 is a combination gas valve built for furnace installations. It handles liquid propane, liquid propane/air mixtures and natural gas in a straight-thru flow configuration.
Thermal and pressure range
The valve operates continuously between -40 degrees F and 175 degrees F. A mechanical thermostat and a pressure regulator are included in the assembly for direct control of gas delivery.
Sustained heating capacity
Maximum heating output is rated at 240 000 BtuH for prolonged furnace cycles. Pilot and main port connections use 1/4 in and 1/2 in to 3/4 in sizes respectively for standard piping.

Questions about this item
How do I install the 700-504 gas valve and what step is commonly missed?
Connect the 1/2 in or 3/4 in ports for straight-thru flow and the 1/4 in pilot port; the step often missed is verifying the pressure regulator is set for the specific gas type before lighting the pilot.
What maintenance or replacement will the 700-504 valve need over time?
The mechanical thermostat and pressure regulator are the primary wear items; plan to inspect the pilot assembly and regulator diaphragm annually and replace the complete valve if the thermostat fails to hold calibration.
What is the first limit reached during sustained high-fire operation?
The 240,000 BtuH heating capacity ceiling is reached before the 175 °F maximum operating temperature under continuous full-load firing.
