FAQs

1) Can I use broken windshield glass in my fireplace or fire pit?

Windshield glass has a film in it which is similar to a plastic or laminate – this is not suitable for use in fire and will burn and turn black.

We DO NOT buy scraps or returns like some competitors as these glass products have unknown ingredients and could be laminated, tinted or not heat treated and is likely not manufactured for use in fire which as a result could create unhealthy air quality when burned. Our Fireplace Glass is not recycled glass (or glass scraps) and Will not burn- It is Clean burning Tempered Glass that is manufactured using a process that “toughens’ the glass and gives it the ability to resist extreme heat without emitting any smoke, soot, or ash and will never burn or discolor, Guaranteed

2) What colors are available in the fire pit glass and fireplace glass product?

From what started as only 6 basic colors available back in 2002 we have expanded our collection of fire pit glass over the last decade into over 50 color choice options that can virtually coordinate with any surround or decor.

Our full glass crystal collection includes: Clear Diamond Crystal, Clear Diamond Nugget, Jumbo Diamond Ice Rock, Alpine Crystal, Alpine Nugget, Jumbo Alpine Ice Rock, Pearl White Reflective, Bronze Crystal, Bronze Nugget, Bronze Reflective, Bronze Reflective Nugget, Midnight Black Crystal, Black Reflective, Platinum Reflective, Sapphire Blue Crystal, Blue Reflective, Cobalt Blue, Cobalt Blue Reflective, Electric Blue, Electric Blue Nugget, Electric Blue Reflective Nugget, Bahama Blue Crystal, Bahama Blue Nugget, Emerald Green Crystal, Green Nugget, Green Reflective, Green Reflective Nugget, Forest Green Crystal, Forest Green Reflective, Gray Crystal, Gray Reflective, Gray Nugget, Auburn Crystal, Auburn Reflective, Copper Reflective, Copper Reflective Nugget, Turquoise Reflective, Gold Reflective, Gold Reflective Nugget, Legacy Premixed, Illustrious Premixed, Sapphire Garden Premixed, Emerald Bay Premixed, Gold Coast Premixed, Venetian Gold Premixed, Red Nectar Premixed, Copper Canyon Premixed, Crystal Cove Premixed, Gold Mine Premixed, and more…

3) Is there any clean up or maintenance required?

Never! The glass does not create any soot, dirt or ashes ever, so even when you’re not using your fireplace the fireplace glass is still sparkling.

4) Does the fire pit glass product ever burn or fade?

When installed as directed on our installation link the glass will never melt, burn or discolor in a fireplace or fire pit that utilizes natural gas as it’s fuel source under normal use.

If you have Propane: Propane gas over time will leave a residue that may slightly discolor lighter colored crystals. When using Propane it is recommended to use Black fire pit glass so that any residue that is created is not as evident- discoloration will only occur in direct flame so lighter colors may be used to accent outside of direct flame if possible.

5) Could you please tell me what sizes the fire pit glass rocks are? An appoximate range of smallest to biggest? Thank you.

Diamond fire pit glass sizes range as follows:

Crystal = 1/4 – 1/2 inch
Nugget = 1/2 – 3/4 inch
Jumbo = 3/4 – 1 inch

6) We just installed a new fire pit in our restaurant. I think the glass would look great inside. I was wondering if it would be possible to get some samples sent so we could decide on a color. We would probably be looking at greens and blues

Our samples are sold on our website in a 1 lb. quantity – this option is available in all fire pit glass colors.
We also offer a sample program where you may purchase up to five fire pit glass samples of your choice and receive a full credit for any samples purchased toward any future fire pit glass purchase within 30 days upon request.

7) Can I use fuel gel on the fire glass?

The glass may be used beside, submerged flush with surface (not covering) or surrounding a gel canister but you can not cover the gel with the glass or it will discolor glass since the gel does not burn as clean as natural gas.

8) We have a 50″ Diameter Custom firepit and trying to figure out the best ring to use?

I would suggest the 36 inch Stainless Steel Triple Fire Ring. This is a triple, high capacity fire ring that will put out a very large flame (when gas on high setting) and provide a spread out flame since it is a triple ring.
The largest ring you could use would be a 48 inch but this ring will only allow 1 inch of clearance on each side of the outer ring – the problem with this is that any breeze outdoors could easily blow the flame outside the pit area.

9) I just finished installing my fire ring and blue glass in my firepit. Looks great. I have natural gas hooked up to it. When I turn the gas up higher it whistles. Any idea how to prevent this?

When a whistle is created it is typically due to a pinch in the line somewhere –
Almost 100% of the time this is created by a flexible extension that may be pinched due to to much bending or bending at too tight of an angle, this will cause a whistle or hiss noise when gas is on high flow setting.
To get rid of the noise you will need to back track to your flex connect and straighten out slightly if pinched too tight. Test burn prior to reinstalling the glass to confirm problem has been solved.

10) I have my new burner installed in my indoor fireplace and am ready to put in the glass crystal. Instructions call for a vented fireplace which I have, but must the flue be open during burning? Mine drops soot when opened and I don’t want to get my glass dirty.

Anytime you are burning gas you should have the vent open in an indoor fireplace.
If your vent is dropping soot down when opened I would strongly suggest getting your chimney swept prior to installing your glass crystals.
This service is normally in the price range of $80-$120 and well worth it if the fireplace has been burning wood or has had it’s fair share of use over the years. Every city has several Chimney sweeping companies, in most cases they can be found by just doing a local search online under the search term “Chimney Sweep”
Once you get your chimney sweep you can install the glass without concern of the glass ever getting dirty with soot from inside the chimney – This is a good idea even if you don’t plan to use the glass crystals as you never know what may be up inside that chimney besides dirt and soot!

11) I would like to know if you service existing fire pits and/or do installations?

We do not provide installation services as we strictly manufacture Diamond Fire Pit Glass products and mainly sell directly to contractors who typically do the installation.
The glass itself is simply poured into the application similar to if you were pouring in sand or gravel.
If you require assistance installing gas pipes or valves any licensed plumber is trained to do this type of service or installation.

12) Can you use the firepit glass in a vent-free fireplace?

Diamond Fire Glass is for use in vented fireplaces and outdoor fire pits only.
The glass product produces a substantial amount of heat that needs to vented – Non vented systems are not suggested as the firepit glass may cause the non vented burner to shut down once a certain (manufacturer preset) heat is exceeded.

13) What is the difference between Diamond Fire Pit Glass and other brands?

Diamond Fire Pit Glass is known for High Quality and Great Service. First we start with the highest quality products available and a wide variety of Colors that you just wont find elsewhere.

14) Do I need a special burner when using propane?

Pan Burners are suggested for use with propane. A pan burner is strongly suggested when using propane to prevent the gas from sinking and collecting underneath the surface, this is a common hazard with propane since propane is a heavier gas then natural gas. THIS IS VERY IMPORTANT- Not using a Pan Burner with Propane could cause an explosion in your fire pit. We also suggest using an LP Converter with propane as this will mix oxygen into the gas prior to burning which helps reduce the weight of the gas and burns cleaner reducing carbon build up.

15) I am building a propane fire pit. Can your product sit directly on the propane tubing or do I need to have the glass sit above the propane tubing. I was not sure if the glass would block the holes producing the flame? Also, Does the glass produce heat like lava rocks?

A propane application usually uses a pan type burner. The glass would sit right on top of the burner and pan.
Glass is a better conductor of heat than lava rocks so you will get more heat with the fire pit glass crystals.

16) Do you recommend using a base of sand or lava rock beneath the glass to increase the heat output and decrease the amount of glass needed, or should I plan on using all glass?

In a fireplace you typically do not use “filler” material unless your fireplace has a “drop down” depth or the floor is not level. This is more common in an outdoor fire pit where you have a large void space beneath the burner. You should not cover the burner with anything other than the glass crystals including sand or gravel/ lava rock as this will produce soot over time that will surface on your glass crystals.

17) What is the difference between the burners in the pan and just the regular u burners?

Typically pan burners are used with propane as propane is a heavier gas then natural gas.
When using natural gas a pan is not required.

18) I am building a wall at the end on my pool that has an opening in it 14′ long and 2′ high, I want to install a gas pipe in the entire thing. Can you help me? Please let me know if this is something that you can build. I like the big double looking flame

We can build a custom pipe for this application.
This would basically be a series of 4 or 5 pipes coupled together out of black iron.
For Example:
Your length is approx 168 inches, We can provide you with (4) 36 inch pipes with couplings attached – you will just need to simply thread these together to achieve the length required.
For a Single burner in the above length the cost would be $199.99
Double Burner in above length = $399.99

19) I am constructing an outdoor firepit with a 35 inch diameter. With the capstone, the opening will be around 32-33 inches diameter. What size of stainless steel burner ring would you recommend? How much clearance is needed if people are going to sit on the capstone?

You should allow a minimum of 6-8 inches from each side.
Since you mention people will be sitting on the capstone I would suggest using the 18 inch fire ring, this will allow approx 8 inches separation from the ring to the outside diameter of the pit.
Keep in mind that outdoors the flame will be exposed to the elements such as wind, going with a larger ring will burn closer to the edge in which case a good breeze could temporarily blow the flame outside the pit enclosure – This is why it is a good idea to isolate the flame a bit more in fire pit applications if you plan on entertaining near or around.

20) I have a regular fire pit and wanted to use the glass instead of wood. I went to my local fireplace store and they told me that the glass is only for gas fire pits. Do I have to convert before using your product?

You will need gas to create the flame, this is correct.
Diamond Fire Pit Glass is an alternative to gas logs or lava rocks, the glass does not burn so the flame source beneath the glass is what creates the actual fire.
Since the Glass crystals do not burn they will never need to be replaced in a gas fireplace, nor will they discolor or melt.
It is normally pretty reasonable to get a gas line run to your wood burning fireplace. I suggest contacting a plumber in your area for a quote on the cost of running gas to your fireplace – this will enable the use of Diamond Fire Glass crystals and is required to use the product.

21) Can I use fire pit glass in a Direct Vent Fireplace?

We do not suggest using Diamond Fire Glass crystals in a non vented fireplace as this type of fireplace is not typically built to handle the heat that may be produced from using the glass.

Also direct vent fireplaces typically ignite by using a pilot, switch on the wall or remote control – this prevents the use of the glass crystals as well because you can not fully cover this type of burner with the glass crystals as the pilot or igniter needs to remain exposed to function properly.

22) I have seen many different suggestions on what filler should be used under the fire ring in an outdoor fire pit – Some suggest Lava Rock others suggest Sand and Your website suggests Pea Gravel, What is the Best and Why?

This is another common question – we have seen many websites suggest contradictory filler ideas and really need to air out the facts of the matter on this subject.

We have always suggested using pea gravel underneath the fire ring when you have depth to fill underneath the fire pit ring. Pea Gravel is easy to obtain at your local Lowes or Home Depot, Etc.- a 50 lb. Bag will cost you under $5.00

But most importantly Pea Gravel is non porous so it does not have any air pockets where gas could collect beneath the surface. Now think about a lava rock – It has nothing but porous characteristics. When using Lava Rocks (especially larger rocks) as a base filler under the Fire Pit Glass you are creating thousands if not millions of little air pockets where gas may collect and hover in the pockets between the rocks as well as in the porous rocks themselves. This can cause the gas that collects beneath the surface to combust all at once after too much gas collects, Especially with Propane!

Using Pea Gravel filler underneath the fire ring essentially eliminates this concern.
Sand is absolutely not suggested as a filler either- Sand retains moisture so it will likely cause your fire ring to rust or corrode much sooner and will also clog the holes of your fire ring when wet.

23) Do you suggest installing your fire ring with the holes facing up or down?

This is one of the most asked questions and you will hear contradicting advice on this subject however we suggest pointing the holes upward for the following reasons:

If you point the holes upward you will get a larger flame! By pointing the holes down the flame is also directed down so you will have to use the gas at a higher gas flow setting to achieve a similar flame as with the holes facing up on a lower gas flow setting – This is far more gas efficient!

Another benefit of pointing the holes upward you are creating heat where you can enjoy it , At the top surface – Pointing the holes downward will direct the heat and flame downward into the base of the fire pit which will heat up the contents of the base as well as the fire pit shell itself which over time could cause it to crack.

24) Can I place a screen over the burner so the rocks don’t cover the holes of the burner?

A screen is not suggested over the fire ring. See our installation link – this will show pea gravel filled up to the base of the burner or fire ring, the gravel will act as a base for the glass crystals as well as fill up any void space beneath the burner.

The glass is designed to sit right on the burner and will not clog the holes of the fire ring, screens can burn over time and cause soot to develop and surface on the fire pit glass.

25) Hello, I love the look of the fire glass to replace my old gas logs but i’m wondering why the glass kits call for a vented fireplace, when my natural gas logs are running in a fireplace that is not vented? any info or advice would be appreciated, as i would like very much to swap out my logs for your glass?

Unfortunately the Diamond Fire Glass product is not suggested for use in non vented units due to the heat that is created from the glass crystals themselves. The heat created from our glass product is far greater than the heat that is created by ceramic log or concrete log alternatives. In addition typically logs that are used in a non vented system are specially made for that purpose and made of alternative materials that do not produce abundant heat.

26) We just bought a burner and 125 lbs. of fireglass from you and we are installing today. I noticed that you sell propane converters but is this really necessary? We have installed the pipe with heat resistant gas pipe tape and the flames look lovely the way it works now. Out propane tank is buried in the yard and runs several things in our home such as our stove, gas grill and now our fireplace. If we don’t install what are the consequences?

The LP converter is suggested so that the propane burns cleaner, this will prevent or minimize soot or ash from developing while burning. Also propane is a heavy gas which causes it to sink and hover beneath the surface which can cause the gas to build up, collect beneath the surface and flare up… using the lp converter reduces this effect as it mixes air into the gas so that the gas is lighter which causes the glass to rise instead of hover beneath the surface. We strongly suggest using an LP converter when using propane.
