What is a millivolt gas fireplace?

What is a millivolt gas fireplace?

Millivolt- Millivolt ignition systems are one of the most proven types of ignition systems in the fireplace industry. A millivolt ignition needs a pilot light lit to work. For the pilot light to remain lit, there is a safety feature called a thermocouple that when heated keeps the pilot light lit.

What is millivolt control on gas logs?

Remote Ready (millivolt) Gas Logs This is the most versatile control valve used on gas logs because you have many options. First of all it is powered by a millivolt generator that is placed in front of the pilot light flame and in turn creates energy from the small amount of heat.

How does millivolt gas valve work?

Millivolt Gas Valve This type of valve makes use of a standing pilot that continuously burns to heat a device, either a thermocouple or thermopile, which then produces a small amount of electricity – less than a single volt, hence “milli”-volt.

How does a gas valve work on a gas fireplace?

Gas flows into a series of valves attached to your gas fireplace. The valves are always closed unless something opens it. This prevents gas from flowing into your home when the fireplace is not lit. A device called a thermocouple will hold open the pilot light valve as long as the pilot light is lit.

Can you run a gas fireplace when power is out?

A gas fireplace with an intermittent pilot ignition (IPI) valve system will remain operational during a power outage.

How many millivolts do you need to open a gas valve?

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 do I know if my gas valve is bad?

If 24 volts is coming from the board to the gas valve terminals and you don’t hear that little clicking noise the internal valve makes, you could have a bad gas valve. To double-check, take the leads off to the gas valve and check there.

Is a gas fireplace blower worth it?

Although a gas blower won’t increase the radiant heat, it will blow the convection heat further into the room than it would have reached normally. Also it is helpful for you to know how a gas blower works. The blower actually takes in unheated air from the room, heats it, and blows it back into the room.

Is it expensive to run a gas fireplace?

The BTU rating of gas fireplaces varies widely depending on make and model. The average price of natural gas in the US in 2020 was around $11 per thousand cubic feet 1, equating to about $1.06 per therm. That means that a 38,000 BTU gas fireplace costs approximately $0.40 an hour to run.

Can a Honeywell valve be replaced on a majestic fireplace?

My Majestic DV360 fireplace had a defective NLA Honeywell valve. This kit made it all better. You will be notching out the supplied bracket to fit under a metal lip. I also had to elongate the three small mounting holes on top of the bracket to allow some side-to-side adjustment. YOU MUST VERIFY THE DIRECTION OF GAS FLOW ON THE NEW VALVE.

What kind of gas valve do I need for a fireplace?

This makes it ideal for fireplace and space heating uses that are vent free. This valve is only for vent free applications. The VS8520, millivolt combination gas controls, are low capacity compact size, millivolt operated gas valves. They are designed for use in small gas appliances, burning either LP or natural gas.

What kind of gas valve does millivolt use?

The VS8520, millivolt combination gas controls, are low capacity compact size, millivolt operated gas valves. They are designed for use in small gas appliances, burning either LP or natural gas.

How big is a millivolt gas pressure regulator?

They include a manual gas valve, safety shutoff, single millivoltage automatic operator and pressure regulator. These valve operates provide automatic main valve operation in the VS820 family of gas controls. The VS8421 Millivolt Gas Valve has a 60,000 Btuh capacity (1 in. pressure drop for straight-through configuration).
