Thinking about specifying a fire pit?

Hemi Firebowl with Ring

Outdoor living is ever popular and products such as fire pits continue to be specified in commercial and residential designs. So what are the considerations for designers?

Solus have put together a guide of useful questions to ask when contacting fire pit companies or as considerations when adding a fire pit feature into a design:

1. What is the difference between the fuel types?

a)  Natural Gas (NG): There is an immediate cost to set up a natural gas line to the firepit but the running costs are the least expensive. Natural gas also burns cleanly. It is the most convenient option as it is always available (no tanks to replace).

b)  Liquid Propane (LP): Like natural gas it can be hard-piped or run a hose (there is very little setup cost for a hose). Typically LPG is available in a variety of tank sizes that need to be refilled and hidden from view.

c)  Ethanol (Bio-Fuel): There is no setup cost. Typically this is the most expensive fuel type. There is less flame control with ethanol (no regulation) and it is the option chosen when either NG or LP are not an option. Ethanol burns with no off-gas or particulates.

d)  Wood: Wood can take up significant storage and require a lot of clean up. Costs of wood really depends on where you live. Wet wood, ignition issues, wood smoke, stinky clothes and neighbour complaints are the most frequent negatives one hears of wood fires. Wood sparks as it is burning and is therefore a potential fire risk. Many regions have bans on wood fires due to forest fires or clean air requirements.

2. Certification? What is it and why should you care?

a)  Certification (ANSI in the USA, CSA in Canada, and CE in Europe). This means the manufacturer (in this case Solus Decor) has paid an independent lab to test our products and certify them as safe according to the industry agreed standards. Part of the certification process is ongoing random audits to make sure that manufacturing standards remain at or above the certification standard. Ask for the certification documents and the product listing. Be wary of counterfeits or “built to the standard of CE, CSA or ANSI”.

b)  One needs to care. Having a product certified means that there is a guarantee that the product has been designed and manufactured in a way that will not be dangerous to the consumer. You wouldn’t buy a gas boiler, furnaceor a BBQ that hadn’t been certified as safe, so why not purchase a safe fire pit as well?

i)  When a product is “built to certification standard,” or “built to UL standard,” it is not actually certified. The product has not undergone the initial testing, nor does it undergo the random testing to ensure the manufacturing quality. The product must be certified and not just to the standard.

ii)  Combining a certified burner with a non-certified vessel or brick assembly may actually void the certification if installed incorrectly and the safety of the fire pit.

Certification also provides a measure of liability insurance for both home owner and commercial installations.

3. Burner / Ignition types.

a) Manual:
A standard ignition that is frequently referred to as a “match-lit burner” in the industry. This burner has an adjustable key valve on the side of the firepit that is used to regulate the gas flow from off to maximum. This burner does not require electricity, just a fuel source (LP, NG or ETH) and is common to North America.

b) Manual with Flame Supervision:
This is the same as the manual ignition, but it has an additional feature that monitors the flames. If the fire pit is blown out, the flame supervision device shuts off the gas flow. With this ignition you light a pilot light that will then warm a sensor. Once that sensor is hot enough the flame supervision system will open the gas flow and ignite the fire pit. This is required in the UK, Europe and some parts of North America. This burner does not require electricity. (only NG or LP).

c) Electronic (Auto):
It requires 110 volts (NA) or 220-240 volts (EU) to be run to the fire pit along with a light switch or timer. It is strictly an on/off burner and is ideal for commercial, common use, or public spaces. Flame supervision is included in all Solus Decor’s electronic ignitions.

d) Electronic with Adjustable Valve (Auto Adj):This burner is the same as the electronic burner but it has an adjustable valve on the side of the firepit that allows our customers to regulate the gas flow. This means if the fire is a little too warm you are able to turn it down to a more comfortable temperature. Flame supervision is available in all of Solus Decor’s electronic ignitions. The extra valve also doubles up as an emergency shut off valve – often a requirement of commercial installations (particularly in California, New York and the UK).

e) Ethanol:

Ethanol burners are a basin into which the ethanol is poured. Once it is filled to the desired level (based upon desired burn time) a long wand is used to ignite the ethanol. When finished the flames can be snuffed out with the lid. This burner does not require electricity and may be placed almost anywhere.

4. How does one determine placement? What factors are there to consider? (aside from aesthetic reasons)

a)  Fuel / electricity:

i) The first factor that should be assessed is where can the fire pit be placed and where it will have access to fuel or perhaps more accurately“Where can I run a pipe or hose for the firepit.” This is most importantfor Natural Gas and Liquid Propane burners.

b)  The Material (substratum) the firepit will be placed upon:

i) Many firepits (Especially burner without structures around them) cannot be placed on wood decks, composite materials, or grass.

ii) Solus Decor’s firepits are rated to be placed on all outdoor materials (wood, composite, grass, stone, pavers, or concrete). This is because the burners are designed to throw heat up and out to those seated around the firepit.

iii) Many firepits lose heat in an inefficient manner to the bottom and sides of the vessel which means the vessel and the area around it gets hot. It is important to know if a firepit can damage the material it is placed upon. It also calls into question how many btu’s or kw’s are necessary for your fire pit. If 30 – 50 % of the heat and btu’s or kw’s are lost to the bottom of the vessel it is a waste of fuel.

c) Safety Clearances:

i)  Safety clearances are the minimum required distance a firepit needs to be from combustible materials such as overhang or furniture. This is part of the certification process and in the CSA / CE documentation.

ii)  NG and LP are “controlled flames” unlike wood which is uncontrolled.

iii)  Solus Decor’s safety clearances for our firepits are:
1) 16” or 400 mm from the side of the concrete vessel 2) 6’5” or 1.9m from the FLOOR (not the top of the vessel)

5. Warranties, and why they are important.

a) Just in case. You cannot control the weather. These are outdoor products and sometimes things happen. Warranties matter! Ask about the warranty and how long it is.

b) What is the duration of the warranty? Most warranties are 6 – 12 months – basically one season. Solus warranties are the best in the business (3, 5 and 25 years).

c) Product quality and who deals with your warranty. If a company is not willing to stand behind their product and provide a warranty then do you really want to buy that product?

The depth or breadth of what the warranty covers is also important. Solus certifies and build in-house and is therefore able to properly troubleshoot any issues.

1)  Concrete: All concrete vessels are cast in-house so providing a warranty replacement can be done in a timely fashion if necessary.

2)  Burners: We assemble all of our burners in-house and we are therefore able to troubleshoot issues as well as being able to provide replacement parts if necessary.

6. What media is best in a firepit?

There are four main categories of media for a fire pit.

fire stones

a) Lava Rock: A natural and inexpensive media that is used to reflect heat back out of the firepit. Does not contain heat for long. Solus Decor uses black lava rock as its primary mediab)

b) Fire Glass: This is a tempered glass that is then rolled so that it loses its sharp edges. The glass will get very hot and remain that way for some time after the flame is extinguished. There is the potential to trap Liquid Propane if set up improperly (explosive hazard). This is extremely important.

c) Ceramic Logs: Purely cosmetic and will not maintain heat for long.d) Concrete Media: There are specific formulations of refractory concrete that have been designed to withstand the heat of a fire pit. Solus uses these as “refractory concrete river rocks” around the burner and / or the entire fire pit.

What sort of media (stone, glass or other) can I put in my firepit? Be careful what you find on the internet – there are many inappropriate “fire pit media”. Part of the certification process is that the fire pit appliance is tested with the media. This means the certification says yes to only this media and nothing else (unless it has been certified). There are plenty of media readily available – it doesn’t mean it is all appropriate for your fire pit. Changing the media may invalidate your certification and therefore your insurance.

Heat (BTU or kW) (A BTU or kW is a unit that measures heat produced by a burner/grill/stovetop/bbq etc.)

1)  BTU or kW can be used to generalize how hot a firepit is, however it is not completely accurate.

a)  A better way of saying it might be that the BTU or kW indicates how much fuel a firepit can consume.

b)  How much heat you feel around the firepit can be influenced by the following:

i)  Wind: Strong winds can blow the heat away.

ii)  Efficiency of the burner: Is it directing heat everywhere or is it projecting heat up and out to those around the fire pit.

iii)  Height of the burner: Heat radiates up and out from its source. The lower the firepit the more heat you will feel on your body.

iv)  Fuel type: For example, propane burns a little hotter and brighter than natural gas.

2)  Many jurisdictions limit how many btu’s or kw’s the burner is allowed to produce.

a) Having a 300,000 BTU burner may or may not be acceptable to your jurisdiction and ergo your insurance company. (Even if it is certified). Additionally, is a 300,000 BTU burner necessary and how much would it cost to run?

What other functions can the fire pit perform? Will it be needed to place drinks on the side while on? Can it be used as a table when not on? Will it have a sculptural presence in the garden? Will it complement the design / furniture / planting scheme and colour?

7. Important questions to ask yourself about what firepit you wish to own.

1)  What shape would work best in your space?

a) Square shapes fill a space more completely.

b) Round shapes are easier for people to navigate around and pull up additional seating.c) Rectangular shapes can fit more people around them than square.

2)  What are you hoping to do with the firepit?

a) Is it going to be solely for sitting around and using as a firepit?
b) Would you like to use it as a coffee table during the day?
c) Would you like to leave your drink on the firetable as you relax around it?
d) Would you like to use the firepit occasionally as a cooking surface?
*NB The proper use of accessories can really expand the uses of your firepit. Solus Decor’s All Metal tabletop with removable center would allow you to use your firepit as a coffee table in the day and at night you can remove the center, so you still have a drinks ring around your flames.

8. What to consider when ordering a firepit.

What style works best for your space? Round? Square? Rectangular? Short? Tall?
What fuel type are you going to use?NG? LP? Ethanol?
What kind of burner / ignition would you like? Manual? Manual with Flame Supervision? Electronic (auto)? Adjustable Electronic (Auto Adj)?
What colour would work best in your space? Solus offers 10 to choose from!

Are there any accessories that would make your firepit more useful? Cover? table top? drink ring?
