We just bought a house with 2 gas fireplaces that require a key to ignite, but there's no key is in sight! How can we determine what type and size key we need?
By Collin C. - NFI Master Hearth Professional on April 1, 2013
Answer:The type of key will depend on the gas valve that you have. Does the gas valve have a round, decorative cover with a small hole in the center? If so, this type of valve likely requires a 1/4 inch key. The decorative cover can be unscrewed and removed to allow access to the valve stem for measurement.

I'm looking for a support piece that goes underneath the end of a steel burner pipe for gas fireplaces. The idea is to keep the pipe level instead of eventually bending downward under high heat. Is there such a device?
By Collin C. - NFI Master Hearth Professional on September 30, 2013
Answer:While we often get a request for this sort of item, I cannot say that I have seen such a support being manufactured. In most cases, a scrap piece of firebrick or square tubing of the proper diameter is used to support the pipe. While it is not the most aesthetically pleasing solution, it is the most common one I have seen.

I have a gas shut off for a fire place and it measures 3/8" x 3/8"
By Kevin E. - Fireplace Specialist on March 1, 2013
Answer:Unfortunately, this is a rather uncommon size. All of our keys fit 1/4" to 5/16" valve stems. A specialty plumbing shop may have a key for your application.
By Martha from Kentwood, LA on May 13, 2013
Do you have an escutcheon that fits a 1/2" male thread?
By Tyler M. - NFI Certified Specialist on May 14, 2013
Answer:Unfortunately, no. Our decorative valve covers are designed to thread onto any standard, 1-inch gas valve body.

I have a fireplace gas valve that fits an 11/32 socket. It's recessed 1.5". I need a shut off key and can't find one in that size.
By Collin C. - NFI Master Hearth Professional on February 7, 2014
Answer:We do not offer a shutoff key in that particular size. Because this size is no longer common, you may need to have a key custom made to fit the valve. I apologize that we do not stock this item.
By Bruce on November 9, 2012
I have a manual gas valve at my fireplace. Usually they only rotate a quarter turn. The one I have turns six complete revolutions from stop to stop. I have a gas log set and am not able to light the pilot. I have never seen a manual valve that was more than a quarter turn. Is there something wrong with my shut off valve?
on November 9, 2012
Answer:While many gas valves are of the quarter-turn variety, there are still many multi-turn gas valves available in the market as well. On average, these valves can turn 4-8 times between fully open and fully closed positions. When the gas valve is completely open and you are attempting to light the pilot on your log set, is the smell of gas present? If so, it is possible the pilot thermocouple is simply defective.

If I remove the knob on my gas cutoff valve, will the universal gas key fit the post?
By Collin C. - NFI Master Hearth Professional on September 30, 2013
Answer:Because there are many different post designs, I cannot say for certain. I recommend removing the knob to check the shape and size of the post. The universal key will only work if the post is square and measures 1/4 or 5/16 of an inch across.
By Lee from USA on November 9, 2012
I need to order a new fireplace key but don't know what size to order. Can you help?
By Staff on November 9, 2012
Just to clarify, are you referring to a key for a manual gas valve, such as this item?
Gas Valve Manual Key
If so, the key that is pictured is the most common type and measures 3 inches in length, with a 1/4" socket end. My recommendation would be to use a small tape measure to determine the depth to the gas valve's shutoff. You may need to measure the depth using a pen or screwdriver. You can insert the pen into the shutoff channel and measure off of the pen, if you do not have a tape measure small enough to fit.
The more difficult thing is determining the size of the shutoff itself. 1/4" is by far the most common, but 5/16" has been manufactured as well. This is really a guess, unless you are able to unscrew the decorative trim collar, shown in the picture of the kit I mention earlier. This is the only way to gain access to and measure the shutoff stem.
By Matt on November 9, 2012
Is it a minor, medium or major project to move a gas fireplace shut-off valve about two feet closer to the fireplace? How much can I expect to pay to have someone relocate it? Is there a major difference between the new valves that you sell?
on November 9, 2012
Answer:Assuming that the current valve is located within a standard sheet rock wall, this would be a medium difficulty project. If the gas piping runs in a fairly straight line towards the fireplace, a plumber could remove the current valve and couple the piping together. The piping could then be cut closer to the fireplace and threaded to receive a new gas valve. The more labor intensive part of the project would be to have the wall patched after it has been cut open to gain access to the piping. Total cost for a project of this size would vary based on your location and any unforeseen issues.
Most of our gas valves are similar in construction. The main differences would be if the valve is straight or angled and if the valve is a standard multi-turn or a one quarter turn valve. Your plumber would be able to tell what type of valve would be needed. If the gas line is running horizontally in the wall, a straight valve is most likely needed.

I have a natural gas log lighter in my fireplace that I want to convert to feed natural gas logs. Do I need to remove the mixer connector from the 1/2" black iron section coming up from the floor or can the lighting tube be removed and the gas log installation begin from there?
By Collin C. - NFI Master Hearth Professional on December 20, 2013
Answer:Any existing mixer for the log lighter would need to be removed. The gas log burners will have their own fuel injector or air mixer. Leaving the existing mixer will cause issues with air to fuel ratio and an incomplete burn.
By Jim from TX on January 31, 2014
I'm running 1/2 inch black pipe 100 feet to a 24 inch 36000 BTU propane log set. Is the pipe size sufficient, and do i need a different on/off valve for propane?
By Collin C. - NFI Master Hearth Professional on January 31, 2014
Answer:Based on the BTU input of the appliance and the length of the run, you are exactly at the threshold between using a 1/2 and 3/4 inch diameter pipe. If the 1/2 inch pipe is being supplied by a 1 inch or larger main pipe, the volume should be sufficient to fuel the appliance. Otherwise, you may want to size up to 3/4, as issues with supply volume could arise. The same shutoff valve can be used between LP and NG fuels, as supply pressures are not far enough apart to make a difference.
By Jon from Yorba Linda, CA on November 8, 2013
The gas company tells me that my backyard natural gas fire pit has a leak in the on position at the valve. Can the existing valve possibly be fixed without ripping out all of the masonry work and replacing the valve?
By Collin C. - NFI Master Hearth Professional on November 8, 2013
Answer:Depending on the design of your valve, it may have a nut that is located just below the control stem. In some cases, this nut can back off slightly and allow the valve to leak. The nut can be tightened down with a deep well socket. If the valve does not have this design, I'm afraid it cannot be repaired without removal.

Do you know if the keyed gas valves are certified / compliant?
By Collin C. - NFI Master Hearth Professional on December 13, 2012
Answer:The maker of the Dante gas valves does have a certification for their products. As such, the Dante valves on our site will carry the CSA certification, which is usually the required certification for use in California, Massachusetts, and Canada.
By Jen from Rochester, Michigan on October 9, 2013
I am looking for a gas valve, key, and floor plate for a 3/4 inch gas line to be used in a fire pit. All I can find is the 1/2 inch size. Do you carry this?

By Lydia Kennemore from Godley, Texas on October 30, 2012
I need to replace the shut off valve for my fireplace. How will I know what size to get?
By Collin C. - NFI Master Hearth Professional on October 30, 2012
Answer:This will depend on the diameter of the gas pipe that is feeding the fireplace. You will need to measure the exposed end of the pipe to verify if the inside diameter is 1/2" or 3/4", as both sizes are commonly used.
By Nathalia from Holly, MI on February 11, 2014
I'm looking for a key to our fireplace. We bought the house last year and the house was missing the fireplace gas key. All I know is that the valve is brass and has a symbol of a penguin. I'm having a hard time finding a key. Can you help? The fireplace is a Majestic brand. It appears the key should be a small square.
By Collin C. - NFI Master Hearth Professional on February 11, 2014
It is likely the gas valve uses a standard 1/4 inch or 5/16 gas key. Standard keys are 3 inches in length, but longer versions are also available if the control stem is deeper in the valve. A key such as the Dante Universal Gas Key - 3 Inches - Polished Brass Finish
. The key uses a stepped design that allows it to fit both 1/4 and 5/16 inch valve stems.
By Jan from Antelope, CA on April 5, 2014
I have a Majestic gas Fireplace in my condominium. I'm guessing it's about 20 years old. To the left of the fireplace in the wall is a stainless steel circle which is missing the key to turn on / off the gas. The circumference of the circle is 2". It says L-L at the top and has the Majestic logo at the bottom. There is a 3/4" square opening which leads to the interior projection where the key is supposed to fit over. Do you carry these keys?
By Collin C. - NFI Master Hearth Professional on April 7, 2014
Majestic used several suppliers for their manual gas valves. Most had either 1/4 or 5/16 control stems to open and close the valve. As such, a universal gas key should work, as it has stepped openings that allow both sizes to be accommodated. The Dante Universal Gas Key - 3 Inches - Chrome Finish
should be the proper item for your needs.

Do you carry a 3/4" valve for 3/4" supply pipe?
By Magan B. on March 21, 2013
By Tim from Memphis TN on January 22, 2013
I can smell gas when I pass by my shut off valve for my non vented gas fireplace. It shows that it is a Dante shut off valve. Is there a rebuild kit for this type of valve or would I have to replace the entire valve? I need to get this fixed pretty quickly to stop this leaking gas.
By Collin C. - NFI Master Hearth Professional on January 23, 2013
Answer:I'm afraid that Dante does not offer a rebuild kit for their gas valves. However, one option is to purchase the same style of Dante valve and replace the internal ball or globe mechanism from the front, as many of the Dante valves can be accessed by removing the lock nut. If the valve is a sealed type, with no lock nut, the entire assembly would need to be replaced.
By Mallory from Los Angelos, California on September 4, 2013
Hi there. We will be installing columns next to our fireplace but the gas valve will be covered. If we cut a hole in the column it will be about 4 inches behind it. Is there something we can buy to extend it the 4 inches and put the valve cover on the column?
By Collin C. - NFI Master Hearth Professional on September 5, 2013
Answer:This is a common issue that we run into with recessed gas valves, an unfortunately, there is not an extension sleeve that is made for this purpose. However, most gas valves use a standard 3/4 N.P.T. pattern and a male to female adapter in this size can be used to extend and connect the valve and cover. I apologize that we do not carry a specific part for this purpose.
By Al from CA on November 20, 2013
How do I know how to buy the right size gas key?
By Collin C. - NFI Master Hearth Professional on November 21, 2013
Answer:A small tape measure will be needed to determine the depth from the face of the gas valve escutcheon to the stem inside the valve. Then the escutcheon must be removed so that you can measure the width of the gas valve stem. Most escutcheons are threaded on and can be removed by turning them counterclockwise.
By Steve from Cleveland on December 28, 2012
My gas valve shutoff is a larger size, and the local fireplace shops do not carry the bigger key. How do I know what size to order?
By Collin C. - NFI Master Hearth Professional on December 28, 2012
Answer:The largest standard size used in gas shutoff valves is 5/16 of an inch. Are you able to unscrew the gas valve cover and measure the stem?
By Marlo from San Diego, CA on March 7, 2013
My fireplace gas valve has a very slight leak whether the valve is on or off. The gas is leaking through the hole where the key is inserted. Is there some packing that can be inserted to eliminate the leak?
By Collin C. - NFI Master Hearth Professional on March 7, 2013
Answer:Unfortunately, no. Most valves have a male threaded bushing that holds the gas stem in position. The female threads inside the valve will come factory sealed with teflon tape, pipe sealant, or may use a gasket of some sort.
After removing the decorative valve escutcheon, use a deep well socket of the appropriate size to tighten the male bushing. This bushing can often become loose with repeated on/off cycles and will cause the leak you are experiencing. If you cannot tighten the bushing and the leak remains, the sealant may have dried or the internal gasket is failing. This would require replacement of the valve.
By Josh from TN on April 10, 2013
I'm refinishing my floors and I want to know if I can safely remove my valve floor plate myself? Do I need to get a plumber to remove it and come back and replace it?
By Collin C. - NFI Master Hearth Professional on April 10, 2013
Answer:The floor plate/escutcheon is a purely decorative piece that can be unthreaded and then rethreaded without an issue. It has no direct contact with the seal in the gas valve, so a gas leak will not be an issue.

My fireplace key is in the fireplace with a black plastic knob on it. I burn my hand when I try to turn it on. Is there an extension for this key? I'm attaching an image.
By Collin C. - NFI Master Hearth Professional on February 4, 2014
An extension that works with almost all pilot assemblies is the Hearth Products Controls 4 Inch Safety Pilot Stem Extension
. You will need to pull the knob from the existing stem, install the extension on the end of the existing stem, then push the knob in place on the end of the extension. The extension uses a half circle shaped attachment on both ends. Please verify your existing stem and knob is the same.
By Mike from North Jersey on February 4, 2014
I am running a 1 inch gas line up from my crawl space, to my first floor, then 90 degrees outside for a generator hookup. I was thinking of using a key to turn the gas on/off from the inside. Do you have any thoughts on this?
By Collin C. - NFI Master Hearth Professional on February 4, 2014
Answer:While I am not certain with the gas codes in regards to gas fired generators, it is common for code to require a gas shutoff in the immediate proximity of the unit using the fuel. It would be prudent to check with local codes to be sure. Usually, keyed valves are not available for a 1 inch line. Ball valves are the most common type used.

Can the lock valve be moved?
By Collin C. - NFI Master Hearth Professional on August 8, 2013
Answer:I am assuming you are referring to the shut off valve? If so, yes it can be relocated. However, it will require cutting into the wall and cutting/threading the pipe, which can indeed be an undertaking.

I have a hole in my floor near the gas fireplace. I have the Dante key that fits. Does a Dante key turn counterclockwise for "on"?
By Collin C. - NFI Master Hearth Professional on November 27, 2013
Answer:The valve would actually be the determining factor as to which way the key would need to be turned. If it is a standard valve, turning the key counterclockwise should indeed open it. However, there are some brands on the market that are reverse threaded.
By scott from San Diego on December 30, 2012
What size key does a Majestic fireplace manufactured from 2006 or 2007 use? It seems that both 1/4 inch and 5/16 inch do not fit!
By Collin C. - NFI Master Hearth Professional on December 31, 2012
Answer:The key required will depend on the fireplace. Do you have the model number of the fireplace installed? Is this a wood-burning unit with a gas starter or a gas unit?
By Joe from Florida on January 16, 2013
Can the valve for the fire log starter be inside the firebox?
By Tyler M. - Fireplace Specialist on January 16, 2013
Answer:The shut-off valve can be close to the firebox, but not inside it. Usually it is placed on the wall next to the fireplace opening in the floor on the hearth of the fireplace.
By Joe from Danville, California on March 11, 2014
I have two gas fireplaces; one with HearthMaster lighter valve and the other with ProFlo lighter valve. My Blue Flame Key works or fits for the HearthMaster valve, but not for ProFlo. Is this because I need different key size?
By Collin C. - NFI Master Hearth Professional on March 12, 2014
Answer:It is likely that the control stem for the two lighters is a different size. Some gas keys are sized to operate either a 1/4 inch or 5/16 gas stem, while others are stepped in size and can operate both. If possible, you can measure the width of the square control stem to determine the sizing.
By Shawn from Kansas City, MO on February 26, 2013

By Tyler M. - Fireplace Specialist on February 26, 2013
Answer:Yes, our valves and covers can be installed in a wall next to the fireplace.
By Ed from Hammond, IN on November 27, 2013
Should the keyed valve on a brand new gas fireplace installation be a ball or globe valve?
By Collin C. - NFI Master Hearth Professional on November 27, 2013
Answer:Either can be used and they have their own unique advantages and disadvantages. A ball valve is easy to turn on and off, as it only has a 1/4 turn effort, but it is not ideal for trying to control gas flow to a fireplace, as there is little adjustment and they tend to whistle. A globe valve is able to be adjusted for flow, as it takes 5 to 6 turns from fully open to fully closed. However, this can be tiresome if you are only using the valve as an on/off shutoff. Globe valves also tend to wear out more quickly than ball valves.
By Joel from Greeley, Colorado on March 12, 2014

By Greg from CA on August 10, 2013
Hello, we recently purchased a home without a key for the gas fireplace. The closest ratchet size that fits over the valve is 3/8", but that is a hair too big. Would you know the correct size to order?
By Collin C. - NFI Master Hearth Professional on August 12, 2013
Answer:The closest standard key size that would be close is a 5/16" key. However, it is possible that the gas valve uses a manufacturer specific key that is not a common size and it could be metric.
With the wall escutcheon removed, use a tape measure to determine the width of the valve stem. That should identify the exact key size needed.
By Steven from Michigan on February 27, 2014

By Ricky from Tulsa on November 23, 2013
I live in an older home. We have gas logs and the valve and key are away from the fireplace. The key broke and I am looking for a new key. Most of the ones that I have found are too large to fit into the flange. I measured it and it seems to be about a 1/2 inch opening. Is there a key to fit this?
By Collin C. - NFI Master Hearth Professional on November 25, 2013
Answer:Modern gas keys do indeed have a flared socket that is larger than 1/2 of an inch. It is likely that your valve and key setup is an older design that is no longer being produced. Your best option would be to have the existing key repaired, if possible or to have a custom key made. Switching to a modern key would require replacement of the gas valve as well.
