What is a millivolt ignition system

Millivolt ignition systems use a standing pilot light. This type of ignition system does not require any external power. … The pilot light can be turned off for extended periods of non-use and them re-ignited when needed. Millivolt are the most common ignition type on the market.

What is the difference between millivolt and electronic ignition?

A millivolt system does not require any external power, and operates solely off of the pilot light being lit, whereas an electronic ignition system requires external power, usually a standard electrical outlet.

Can I convert my gas fireplace to electronic ignition?

Some gas fireplaces can be upgraded with electronic ignition systems to boost fuel conservation and efficiency. The savings you realize from the use of an electronic system will far outweigh the small cost of the change. This applies whether you retrofit your old fireplace or completely change the system.

How does a millivolt system work?

The most common type of gas fireplace uses a millivolt ignition system. The piezo ignitor is usually connected to a button that generates a spark when depressed. … The thermocouple generates about 20-30 millivolts, enough electricity to keep the part of the gas valve that controls gas flow to the pilot assembly open.

What is millivolt control on gas logs?

1. Millivolt Gas Valve. … This small amount of electricity provides enough of a current to control an electromagnet that pulls the valve open against a spring; if the current isn’t present, the valve will snap shut and turn off the gas.

Do Thermopiles go bad?

Like the other component parts in your furnace, the thermocouple can wear down over time, producing lower voltage than it should when heated. And the worst part is that you can have a bad thermocouple without even knowing. Therefore, inspecting and testing your thermocouple should be part of your furnace maintenance.

What does IPI mean in gas stoves?

IPI (Intermittent Pilot Ignition) is when the pilot light is only lit when the control board gets the call for heat, either from a thermostat or from someone flipping a switch. CPI (Continuous Pilot Ignition) is when the pilot is lit constantly.

How many millivolts should a thermocouple produce?

Thermocouples designed for residential gas appliances, such as fireplaces, water heaters and furnaces, are made for 30 Millivolts. The reading should be between 25 and 30. Anything under or hovering around the 20 millivolts mark means the thermocouple needs to be replaced.

How many millivolts does a good thermopile produce?

A healthy thermopile in an open circuit test will read between 650 to 850 millivolts or somewhere in between. If the open-circuit test reads below 400 millivolts, then the thermopile likely requires service or replacement.

How does a millivolt thermostat work?

Millivolt Thermostats Unlike low-voltage systems, they do not require a step-down transformer and are not connected to the household wiring system. Instead, they are self-powered by a special thermocouple device called a powerpile or thermopile generator that produces direct current (DC) electricity.

Are gas fireplace remotes universal?

Whether or not you can use a fireplace remote with your fireplace will mostly depend on your gas valve type. Most of our remotes are designed to be used with millivolt gas valves, but we also have options for other specialty valves like servo motor valves and latching solenoid valves.

Can you add a switch to a gas fireplace?

Most gas fireplaces have a switch mounted in the front, under the fireplace. For a more convenient control option, you can install a remote switch in a location that is more accessible.

What is match light ignition?

The traditional method to igniting a fireplace, a match lit ignition system requires the flames be lit manually by holding a matchstick or a long lighter near the burner before opening the gas valve. … A match lit ignition system has little to no moving parts, meaning less maintenance is required.

What is continuous pilot mode?

CPI – Continuous Pilot Ignition, means your pilot light stays on constantly, even hen the fireplace main flame is not on. IPI – Intermittent Pilot Ignition, means your pilot is lit only on demand to ignite the main burner, right after you turn the fireplace on.

What is a standing pilot on a gas fireplace?

A standing pilot light is a part of the burner system within a gas fireplace that stays lit and is capable of holding a constant flame whether the fireplace is burning or not. The standing pilot is lit by first turning on the main gas valve on the outside of the fireplace.

How does an intermittent pilot ignition work?

Rather than keep a flame burning all the time, the intermittent pilot only lights when needed. The system responds to the command for heat by using an electric spark to ignite the flame. A sensor registers the flame and lights the main burner, at which point the pilot light goes out.

How much does a thermocouple cost?

It costs $150 to $250 to replace a thermocouple. It checks to make sure the pilot light is on.

Will pilot stay lit if thermocouple is bad?

The job of the thermocouple is to keep the pilot lit. It does this by sending a tiny electric current to a sensor on the gas valve signaling the valve to stay open. … Nothing lasts forever, and when the thermocouple wears out, the pilot won’t stay lit and your appliance won’t work.

Are thermal couplers universal?

Thermal couplers are very similar, but the length and fittings used to install them can differ. The universal lead-length gas thermocouple is designed for gas furnaces and 30 millivolt systems. It includes universal connections for adapters and is compatible with pilot screw, push-in or clamp burners.

How many millivolts should a pilot generator produce?

The normal millivolt output is 25 to 35 millivolts; on some, you may even get up to 35. The other part of this safety pilot system is the electromagnet (power unit).

How many millivolts should a flame sensor have?

When the flame lights, you should read between 0.5 and 10 microamps (μA), depending on the furnace. Readings between 2 and 6 are common.

How many mV should a thermocouple read?

Ideally, the reading should range between 12 mV to 15 mV. If the thermocouple outputs voltage below 12 mV, there is a significant drop, meaning that it is defective and needs to be replaced.

How far should thermocouple be from pilot?

Remove the pilot tube from the gas valve and spray compressed air to clear it. When working properly in most gas appliances, the pilot flame should hit the upper 1/2 to 3/8 of the thermocouple. If the pilot has a weak, orange-yellow flame or barely reaches the thermocouple, it’s too low.

How do I install a millivolt thermostat?

1. Turn off the electricity to your heating unit, such as a furnace or boiler.
2. Connect one thermostat wire to one screw terminal on your millivolt thermostat’s wall plate. …
3. Connect the second thermostat wire to the second screw terminal on your thermostat. …
4. Turn the electricity back on to your heating system.

Is there a millivolt thermostat?

Millivolt systems require a specific type of low voltage thermostat. Designed for use with gas fireplaces and some heating systems, our selection of millivolt thermostats can be used with or without an external power source.

Does a two stage furnace need a special thermostat?

A two-stage thermostat may need more wires than your current programmable thermostat. … If you plan to keep your home at a constant temperature, you don’t need a two-stage thermostat. If you want to vary the temperature of your home during the day or night, a programmable two-stage thermostat is the way to go.

What is the wall switch for on a gas fireplace?

The wall switch sends an electrical signal to your fireplace to open a valve and release the gas for the pilot light to light it. Without power most fireplace valves will not open.

What is the switch on my gas fireplace?

It’s easy to know how to turn on a gas fireplace with an electronic ignition wall switch. Many gas fireplaces come equipped with a wall switch control panel for activating the unit and adjusting the level of the flame. Simply push the “On” button and the pilot should ignite.

Can you use a smart switch on a fireplace?
