# Robertshaw Millivolt Gas Valve Wiring Diagram

Robertshaw millivolt gas valves are a type of gas valve that uses a millivolt signal to control the flow of gas. This type of valve is often used in residential applications, as it is relatively inexpensive and easy to install. Millivolt gas valves are also very reliable, and they can last for many years with proper maintenance.

How Does a Millivolt Gas Valve Work?

A millivolt gas valve works by using a millivolt signal to open and close the valve. The millivolt signal is generated by a thermostat, which sends a signal to the valve's controller. The controller then sends a signal to the valve's solenoid, which opens or closes the valve. The millivolt signal is very small, and it is important to use a shielded cable to prevent interference from other electrical signals. The cable should also be as short as possible, as this will help to reduce the amount of noise that is picked up by the cable.

Wiring a Millivolt Gas Valve

Wiring a millivolt gas valve is a relatively simple process, but it is important to follow the manufacturer's instructions carefully. The following steps provide a general overview of how to wire a millivolt gas valve: 1.

Disconnect the power to the gas valve.

This will prevent any injuries from occurring if you make a mistake while wiring the valve. 2.

Locate the gas valve's terminals.

The terminals are usually located on the side of the valve. 3.

Connect the thermostat wire to the valve's W terminal.

The W terminal is usually labeled with a "W" or a "white" wire. 4.

Connect the power wire to the valve's R terminal.

The R terminal is usually labeled with a "R" or a "red" wire. 5.

Connect the ground wire to the valve's G terminal.

The G terminal is usually labeled with a "G" or a "green" wire. 6.

Reconnect the power to the gas valve.
