I'm looking for a square fire pit pan and burner (natural gas) to fit a 39" opening. Can you point me in the right direction?

I have a 24 inch square fire pit and I will be using a 20 lb propane tank. What size burner should I use? I want to control how big the fire gets. Do i need an adjustable regulator or just a ball gas valve? Do i need an air mixer? I want the tank to be at least 10 feet away but I'm not sure what I should use to achieve that. What would you suggest?
By eFireplaceStore on September 29, 2014

For a 24 inch pan, the correct burner to use is a Hearth Products Controls Square Stainless Steel Propane Outdoor Fire Ring - 18 Inch. The unit will include an air mixer as standard, although a globe or ball type shutoff valve will need to be used. Although a 20 pound LP cylinder can be used, I highly recommend sizing up to a 30 or 40 pound version. The 150k capacity of this burner will limit operation to approximately 1 hour at a time on a 20 pound tank. A standard LP bottle regulator can be used, with the flow adjusted to between 10 and 14 inches of water column. Either copper or iron pipe can be used to supply fuel to the burner.

I'm building a firepit with a 38" inner diameter, should I get a 30" or 24" gas fire ring? Do I need a pan if I'm using natural gas? Do I need high capacity?
By Collin C. - NFI Master Hearth Professional on April 29, 2013

Based on the diameter of your pit, a 30 inch fire ring would be the most suitable size. I do recommend using a pan to support the surrounding media that you may use, such as glass, logs, or lava rock. We do offer pans that measure 36 to 37 inches and can be supported from below or by the surrounding fire pit wall.

A high capacity burner will offer taller flames, but nearly doubles the fuel usage of the burner. It is simply personal preference as to what capacity burner will be used.

When would I need a plate underneath my burner?
By Chris on October 17, 2013

A pan is strongly recommended in any gas firepit installation to provide water drainage of any rainwater. The pan also provides support for the burner and any media that is placed over the burner assembly.

Can I use a 24" burner kit in my custom fire pit? It has a 30" steel ring that goes around it. How much flame would a double ring, 24" burner produce?

By Collin C. - NFI Master Hearth Professional on May 28, 2013

From your description, a 24 inch fire ring could indeed be used for your installation. If you are looking for the highest flame possible, you will likely be interested in going with our Hearth Products Controls Round Stainless Steel High-Capacity Match-Lit Natural Gas Fire Pit Insert Kit - 24 Inch, as this unit yields 300,000 BTUs of heat. This will yield a flame approximately 18 inches tall. Please keep in mind that a larger, 3/4" supply line will be needed for this burner, as a standard 1/2" line will be unable to meet the demand.

By Dan from Lake Zurich, IL on September 16, 2013
We are working with a landscaper to build a natural gas outdoor fire pit. We have a 30" diameter pit circle in the middle of a larger circle where there is approx 5' between the fire circle to the seat wall. Can you recommend how many BTUs you would potentially target to be able to heat the area in colder weather (we live in the Midwest), and also to roast a hot dog or marshmallow?
By Collin C. - NFI Master Hearth Professional on September 17, 2013

For your application, I recommend a 24 inch high capacity ring. The suggested item is the Hearth Products Controls Round Stainless Steel High-Capacity Match-Lit Natural Gas Fire Pit Insert Kit - 24 Inch. This complete assembly will include the control valve and lava rock for the pit. The 300K BTU capacity is a significant uptick over the 150K standard burner and should offer good heat output for your seating area. The system is also sized to be used with any of our 30 inch burner pans, which would be a drop in fit for your application.

By David from Jacksonville, FL on December 9, 2013
I am having a natural gas firepit built, and am told that there is a requirement (in Florida) that it has to have a gas shut off if the flame blows out. Do your burners come with this?
By Collin C. - NFI Master Hearth Professional on December 10, 2013

The flame sensing feature that you mention will be dependent on the gas valve, as opposed to the burner. Every match lit burner without an automatic gas valve will not have this feature. However, any of our manual or electronic gas valves will have a flame sensing feature that will shut down gas flow to the burner, should the flame blow out. If you would like to provide the dimensions and shape of the burner that you are looking for, I can provide options that will work for you.

I am looking to install a natural gas firepit burner. The inside diameter of the pit wall is about 37". What size burner do you recommend?
By Collin C. - NFI Master Hearth Professional on October 13, 2013

For proper appearance, a 30 inch burner ring should be used. A product such as the Hearth Products Controls Round Stainless Steel High-Capacity Match-Lit Natural Gas Fire Pit Insert Kit - 30 Inch would work well. We also offer both bowl and pan components to mount beneath the ring itself, if you require such an item to hold decorative media. The pit could be filled with limestone or pea gravel as well.

By Rod from Wellington, UT on August 30, 2015
Is there a systematic calculation to understand the proper burner size and relation to BTU output? Also, do all of the burners run off of a standard propane tank?
By eFireplaceStore on August 31, 2015

The manufacturer generally sizes the BTU input rating of each burner to be proportional to the diameter or dimensions of the burner tubing. In some versions, there are high capacity models. Standard capacity versions are sized to maintain a 10 inch flame height, while high capacity models can reach up to 14 inches in height.

Because of the high demand of most burners, it is recommended to use at least a 40 pound LP tank for optimal performance. A standard 20 pound tank will only operate even a 90K BTU burner for about 4 hours.

By Peter from Milton, MA on July 7, 2015
I have a 32 inch round opening fora natural gas fire pit. the gas hook up is already installed. I would like a kit that will drop into the masonry structure and be lit by an ignition button or match lit. What size of pan and kit should I get? Are there any models that you would recommend?
By Will M. on July 7, 2015

I would recommend either the 31 Inch Stainless Steel Bowl-Style Natural Gas Fire Pit Insert for push button ignition or the High-Capacity Match-Lit Natural Gas Fire Pit Insert Kit - 30 Inch along with a Stainless Steel Fire Pit Pan - 31 Inch for a manual or match lit system.

By John from Romeo, MI on September 9, 2014
I'm building a fire pit using retaining wall blocks and plan on having a 32" inner diameter opening. If I purchase either the 13" or 24" Campfyre burner will I still need a subplate to hold the burner in place? Question 2: I'm looking to have the wood log look, which burner size would best fit my opening? It looks like a fire in the middle of the logs gives the best appearance. Any suggestions?
By eFireplaceStore on September 9, 2014

You will indeed have to supply some sort of support system for the burner pan, be it stacked cinder blocks beneath the pan or rebar cross supports. For the size of your opening, the 24 inch burner would be the best size. This has an inner and outer ring, with larger perforations on the inner ring for a higher center flame.

By Quent from St. Paul, MN on August 19, 2014
I am building a 42 inch diameter fire pit which will use LP. How big of a burner kit do I need? What is the ideal BTU output? Do you have any suggestions?
By eFireplaceStore on August 20, 2014

If the 42 inch diameter you reference is the opening width, a 36 inch diameter ring would be the ideal size to use. An example of a burner that would work is the Hearth Products Controls High-Capacity Round Stainless Steel Propane Outdoor Fire Ring - 36 Inch. It is common to use a support pan beneath the burner, but this will depend on the depth of your fire pit. If you would like to provide further details of the construction, I will be happy to advise further.

Is it possible to get a gas fire pit top only?
By Kevin E. on January 11, 2015

We primarily only carry components for the firepits that we offer on our site. However, you may find a cover that would work for you in our Fire Pit accessories.

By Trent from Calgary, Alberta, CAN on March 10, 2015
I am in the process of buying 2 natural gas firepits however, I want to increase the BTU's to 150,000 on both as well as change the design of the flame and add glass. Is all I need a proper size burner, the burner pan, and fire glass?
By Will M. on March 10, 2015

Depending on the size of your fire pit, you would need to change to a high capacity burner like the Hearth Products Controls Rectangular Stainless Steel Match-Lit Natural Gas Fire Pit Insert Kit - 18 Inch x 9 Inch that would come with everything necessary to make this change, aside from adding just enough fire glass to cover the burner ring. Our fire pit burners can be found here.

By Dave on November 9, 2012
Our fire pit has a dual ring burner (rusted) with lava rock and the flame is blue. Should there be an air flow adjustment? Is the stainless steel burner better? We are considering the glass but still might use the logs. What do you think?
on November 9, 2012

Most likely, the blue flame is being caused by a fuel mixture that is too "rich" or fuel heavy. There should be an air shutter or air valve that can be opened to balance the incoming air to the burner assembly. This is usually located on or near the gas valve for the unit. Stainless steel is definitely the preferred material for outdoor use, as it not only stands up to precipitation, but can more readily deal with the large volumes of moist air that is drawn into the pit for combustion. Fire glass is becoming increasingly popular, both for the contemporary look and for the low maintenance aspect of the glass. The glass can last for years and requires virtually no maintenance.
