Copeland 36c01a405s1 Gas Valve 24V 3/4 Inch Fpt Ng Lp

Product Description

The COPELAND 36c01a405s1 is a combination gas valve designed for use with natural gas and liquid propane (LP) fuel systems. Operating on a 24-volt control circuit, this valve provides electromechanical shutoff and flow regulation in gas-fired heating equipment. The inlet and outlet connections are 3/4 inch female pipe thread (FPT), making it compatible with standard gas train piping configurations. Licensed HVAC technicians and gas appliance service professionals install this type of valve as part of routine equipment servicing or component replacement on residential and light commercial heating systems.

This valve is suited for residential and light commercial gas-fired equipment, including furnaces and boilers that use standard 24-volt low-voltage control circuits. Its dual-fuel rating for natural gas and LP allows deployment across a variety of fuel configurations without requiring a separate valve for each gas type. The 3/4 inch FPT connections align with common residential gas supply line sizing, supporting straightforward drop-in installation in existing piping layouts.

Key Features

• Rated for both natural gas (NG) and liquid propane (LP) operation
• 24-volt control voltage compatible with standard low-voltage thermostat circuits
• 3/4 inch FPT inlet and outlet connections for direct piping integration
• Single-unit valve simplifies replacement in gas-fired heating systems

Compatibility

Designed as an OEM-style replacement gas valve for residential and light commercial gas-fired heating equipment with 3/4 inch FPT gas connections and 24-volt control circuits.

Installation Notes

Installation must be performed by a licensed HVAC technician or qualified gas service professional in accordance with local codes and the applicable provisions of the International Fuel Gas Code (IFGC). Shut off the manual gas supply at the upstream service valve and de-energize the 24-volt control circuit before removing the existing valve. Verify all connections are leak-free using an approved leak detection solution after restoring gas supply. Never use open flame to check for gas leaks.
