Fuel Requirements

Fuel = Flame

Fuel Types

There are various pros/cons of Liquid Propane (LP) and Natural Gas (NG). The difference between LP and NG Warming Trends burners are the “jets”. If, down the road, you need to convert from LP to NG or vice-versa, you can do so by purchasing replacement jets from us at $25 each.

Propane – pros

- Flexibility/portability
- Opens up new location possibilities
- Sometimes NG is not available

Propane – cons

- More expensive to burn than NG
- Heavier than air, so it sinks down. This makes ventilation more important.
- Requires refilling the tank
- Hiding the propane tank can present new aesthetic challenges
- Black soot tends to build up faster on fire media such as ceramic logs and cannonballs (it can be cleaned off)

Natural Gas – Pros

- Cheaper to burn; you probably won’t even notice an increase in your gas bill. Clients of ours have reported $0.25 – $0.75 per hour
- You won’t run out, so burn to your heart’s content without the dreaded “we’re out of gas”
- Since it’s lighter than air and rises, there’s less likelihood of unwanted fuel accumulation in the vessel
- Slightly cleaner burning; less soot build up

Natural Gas – Cons

- Limited to what’s available in your area
- May require upgraded meter or larger diameter fuel lines to provide adequate BTUs
- The volume and pressure can be affected by other appliances
- Might require a longer gas line, depending on where your fire feature will live
- Would be difficult to change the fire feature’s location after installation
- Check the side of your gas meter for a BTU rating. Most commonly they are rated at 250K BTUs

Gas Line Sizing

Even though the standard key valve inlet is 3/4″, you may need a larger gas line to span long distances.

In order to get the proper volume and pressure of fuel, you need a gas line that is large enough in diameter to carry it sufficiently. For the most accurate assessment, consult a fuel professional. For a rough estimate, utilize our gas line sizing charts below.

*Make sure the BTUs from your line can supply at least 60-70% of what the burner is rated at.

Propane Gas Line Sizing Chart

Natural Gas Line Sizing Chart

Gas line sizing variables

- Using angled couplings can reduce the volume/flow of fuel
- Adding a 90 degree angle in your line adds the equivalent of 5 feet of distance
- Running different sized lines over various distances is acceptable, but for maximum fuel volume, run larger lines over long distances
- Number of appliances, whether it’s a dedicated line or not; all these factors play a role in volume and pressure
- Pro Tip: if you haven’t installed your gas line yet, consider running it in conduit so that if you ever need to repair or change it, you won’t have to dig it up

You can have great gas pressure, but if your line is too small, you may not get the desired flame. Think about it like filling up a swimming pool. If you reduce the nozzle size significantly, you may have a ton of pressure, but it’s going to take longer to fill up the pool. You need both pressure and volume to get a great flame. This is why the size of the gas line is so important.

Gas Pressure

Now that you understand the importance of volume (BTUs), let’s talk pressure.

Optimal Pressure:

LP: 11″ water column (w.c.)
NG: 7″ water column (w.c.)

Water Column is the term used to measure pressure. There are 27.7 inches of water column pressure in 1 PSI of pressure. So 7″wc is about 1/4 PSI. This is the normal pressure that household natural gas is delivered.

The device used to measure pressure of this type is called a Manometer

Pressure too High? You may experience unwanted noise

Pressure too Low? The flame will not be as tall and hot

Gas Stub Location

Location of Gas Stub

Most commonly the gas stub is positioned underneath the fire feature so that you don’t see it
It can be off-center or on-center, depending on the size of your fire feature
You may want to go off-center if you’re using electronic ignition
The key valve is generally located on the side of the fire pit, so if it makes sense for your build, place the gas stub off-center to reduce the distance of gas stub to key valve
Most often, the plumber will use hard pipe to connect from the gas stub to the key valve. However, if they decide to use a flexible line, most lines are 36″ long, so it makes sense to try and keep the gas stub within 36″ from the key valve location
Instruct the contractor to keep the gas stub as low as possible to make room for electronic ignition, or in the case that the plate sets fairly low
On some builds, the plate sits only 8″ off the ground

Regulators & Air Mixers

You DO NOT need an air mixer with any of our burners. Air is mixed at each jet.

LP Regulators

- For optimal regulation for burners over 250K BTUs, contact a local propane supplier
- For regulators 250K BTUs or lower, purchase our REGULATOR KIT
- From the tank, propane is HIGH PRESSURE, so it must be regulated down, because the burners are low pressure
- For longer gas lines, we often use a high pressure (10psi) regulator at the tank end, and a “2nd stage” regulator on the other end of the line to bring the pressure to 11-13″wc

NG Regulators

- Consult a professional (plumber/HVAC)

Using a Propane Tank

Standard 20lb Tank

A standard 20lb/5 gallon BBQ propane tank can be used for burner systems 180K BTUs and under
The Canyonlands Fire Table is a complete unit that can have a self-contained propane tank
Burn time varies from 6-12 hours, depending on how hot you run it
Results may vary, and it is common for the fuel to “freeze up” with burners 180K BTUs and up. What that means is that after 45 minutes or so, the flame only goes to about half. Remedy this by using two tanks connected together

40lb Tank

This is a better option for most of our burners from 100K to 200k BTUs
It will give you longer burn times
Still relatively small and easy to move

High Volume Tanks

Contact your local propane supplier

Hiding the Tank

You can always run a larger diameter line and hide the tank in an inconspicuous location
You can purchase 20lb propane tank covers that make hiding the tank a cinch

Gas Consumption

All of our burners burn with incredible efficiency due to the engineered jets. They mix fuel and oxygen at the flame which makes it taller, brighter, and hotter using less fuel

Permits & Certifications

Compliance with the following standards:

ANSI Z21.97/CSA 2.41 Outdoor Decorative Gas Appliances
The burner system is certified nationally, however, it is up to the customer or contractor to verify local requirements

Canadian Customers

Most metropolitan areas in Canada will require an automatic shutoff for fire pits over 65K BTUs in order to get a permit or certification.

Our Premium Electronic Ignition system has the proper fuel and flame censors to automatically shut down the fire when needed. Combine it with a dial timer to increase safety and ease.
You can still purchase higher BTU burners without the premium ignition, and we will ship it with a fitting that limits the burner to 65K BTUs in the case that you’d like to have it certified.

Plates & Pans

Do you need one?

The Purpose

The main purpose of the plate or pan is to hold in the media (lava rock, glass, etc). It also acts like the hood of a car, in that it can be lifted up and out in order to access the gas line or key valve underneath.

What’s it made of?

Aluminum
Aluminum does not rust

Is it ALWAYS necessary?

No, in some cases a plate is not necessary
You may decide to fill up the space with some gravel or lava rock and set the burner on that instead of a plate or pan
Using a plate/pan is the most convenient for installation and maintenance

What Type of Plate or Pan do you need?

Plates (No Sidewalls)

Appropriate for most builds
Sidewalls are not necessary when the burner is in the common position- recessed 3-5 inches below the finished top
Use stacked cinder blocks, bricks, or pavers under the plate. This makes for a simple and sturdy plate mount

Pans (2″ or 3″ Sidewalls. 2″ is Standard.)

If the top of your fire table overlaps, or encroaches into your opening, and its thickness is less than 3 inches, you may want a pan instead of a plate (since the pan has to be smaller than the smallest part of the inside diameter)
The sidewalls help contain the fire media/lava rock

Drop-In Pans (2″ or 3″ Sidewalls + 1″-2″ Lip)

Sometimes necessary if you plan on building a portable fire feature and aren’t able to stack up blocks under the plate
Bar-height or uncommon builds might benefit from a drop-in pan
You will see a brushed aluminum metal band on the top of your fire feature when you use a drop in pan
Drop-in pans are available as a custom order – CLICK HERE
We recommend 3″ sidewalls with a 1.5″ lip in most cases

Attaching the Burner

Does the plate attach to the burner?

In most cases, yes
- When you order a package from us, most of the time it will come with a threaded piece welded on to the plate/pan
- The burner screws onto it
- It’s very simple to remove or attach the burner (righty-tighty, lefty-loosy… make sure to re-apply pipe dope/tape!)
It’s not required that the burner attaches to the plate/pan. You can set the burner directly on the plate/pan. This will reduce the height of the burner by 3/4″. This might be beneficial if you want to cover your fire feature with a flat cover

Installation Tips

There are many methods to mount a plate/pan inside your fire feature. We’re just going to tell you our favorite way to do things because… well, it has worked well so far! With that being said, these methods may not work in all situations, so put your problem-solving hat on and get creative.

*Complete & RTF Systems: you won’t need to worry about plate/pan mounting; they’re designed for simplicity

Mounting the Plate/Pan

Consider stacking up cinder blocks, bricks, or pavers inside the fire feature cavity
Place the plate/pan directly on the blocks
Adjust the block height by either adding some fill, or by digging underneath
Most commonly, plates/pans are mounted 3″-5″ below the finished top of the fire feature

Plate/Pan Depth

4-5″ below the finished top is recommended
Recessing it deeper may make the fire seem smaller, and you won’t see the media as well
Recessing it to be more shallow can give it a “proud” look; where all the parts stick up high and make a statement. Though you may have to ‘mound’ the fire media up higher in order to cover the jets. It’s not a bad look, but you won’t be able to use a flat metal cover if that’s.
The depth at which the plate sits is really up to you. Keep in mind, the burner sits 3″ high from plate to the tip of the jet

My Plate is Too Big/Small

If your fire feature is already built and you can’t use a standard sized plate, you have a few options:

Cut your plate to size on-site

- Use a jig-saw with metal blade, or a grinder wheel with cutoff
- It’s 3/16″ aluminum and your cut doesn’t need to look pretty

Make your plate bigger

- Use concrete board to extend the size of the plate
- Watch THIS VIDEO to get an idea
