Propane Fire Pit FAQs
General Questions
What is an outdoor propane fire pit?
An outdoor propane fire pit is a gas-fueled fire feature that uses propane as its fuel source, typically supplied by a standard 20 lb propane tank. These fire pits are designed for outdoor use and provide warmth, ambiance, and visual appeal with the convenience of quick ignition.
Why choose a propane fire pit over other fuel types?
Propane fire pits are often chosen because they:
- Ignite quickly with minimal effort
- Produce consistent, adjustable flames
- Do not require firewood or ash cleanup
- Do not require a permanent gas connection
They are commonly valued for convenience, cleanliness, and ease of use.
Propane Tank & Fuel
What is a 20 lb propane tank?
A 20 lb propane tank is the most common residential propane tank size in the U.S. It typically holds approximately 4.7 gallons of propane and is widely available at hardware stores, gas stations, and propane refill centers.
How long does a propane fire pit run on a 20 lb tank?
Estimated runtimes vary based on BTU output:
- 40,000–45,000 BTUs: ~8–10 hours
- 50,000–55,000 BTUs: ~7–8 hours
- 60,000 BTUs: ~6–7 hours
Actual runtime depends on flame height, weather conditions, and efficiency.
How much does it cost to run a propane fire pit?
On average:
- $2–$4 per hour, depending on propane prices and BTU rating
Costs may vary by region and season.
Can the propane tank be hidden?
Many propane fire pits are designed with:
- Built-in tank compartments

- Is common among regular fire pit users
Safety & Use
Are propane fire pits safe?
When used outdoors and according to basic safety guidelines, propane fire pits are generally considered safe. Important considerations include:
- Outdoor use only
- Proper ventilation
- Keeping distance from structures and flammable materials
- Never storing spare propane tanks near active flames
Always follow local fire regulations.
Can a propane fire pit be used under a covered patio?
This depends on local fire codes and the specific design of the fire pit. Some covered patios may allow use with proper clearance and ventilation, while others may restrict it.
Can I leave the propane tank connected when not in use?
Many users leave the tank connected but turned off at the valve. Covering the fire pit and protecting connections from moisture may help extend longevity.
Installation & Placement
Do propane fire pits require professional installation?
Most propane fire pits using a 20 lb tank do not require professional installation and are designed for simple setup. Assembly requirements vary by model.
Where should a propane fire pit be placed?
Propane fire pits should be placed:
- On level, non-combustible surfaces
- In open outdoor areas with good airflow
- Away from overhangs, trees, and flammable materials
Clearance requirements vary.
Can a propane fire pit be used on a deck or patio?
Some propane fire pits may be suitable for use on non-combustible patios or decks. Heat-resistant mats or shields may be recommended depending on surface type.
Materials & Durability
What materials are propane fire pits made from?
Common materials include:
- Steel or stainless steel
- Glass fiber reinforced concrete (GFRC)
- Cast aluminum or stone-look composites
Material choice affects weight, durability, and appearance.
Can propane fire pits stay outside year-round?
Many propane fire pits are designed for year-round outdoor use. Protective covers and seasonal care can help extend lifespan, especially in extreme climates.
Maintenance & Care
How do I maintain a propane fire pit?
General maintenance includes:
- Keeping burner ports clear
- Periodically checking hoses and connections
- Protecting the fire pit from moisture
- Cleaning fire media as needed
Maintenance needs vary by environment and use.
What fire media can be used?
Fire-rated media may include:
- Lava rock
- Fire glass
- Ceramic fire logs
Only materials designed for gas fire pits should be used.
Performance & Conditions
Do propane fire pits produce smoke or odor?
Propane fire pits burn clean and typically produce little to no smoke or odor when operating properly.
Can I control the flame height?
Most propane fire pits include an adjustable control valve. Flame appearance may vary based on fuel level, wind, and fire media.
Will wind affect the flame?
Yes. Wind can:
- Reduce visible flame height
- Cause uneven flame patterns
- Increase fuel consumption
Some users add a tempered glass wind guard or place the fire pit in a sheltered area.
What is a fire pit wind guard?
A wind guard is a tempered glass enclosure that can help stabilize flames, improve heat efficiency, and add a physical safety barrier. Compatibility varies by design.
Do propane fire pits give off enough heat?
Propane fire pits are primarily designed for ambiance. Higher BTU models can provide noticeable warmth, especially for cool evenings, but are typically supplemental heat sources.
Typical Heat Output (BTUs Explained)
Propane fire pits are usually rated between 30,000 and 65,000 BTUs.
Here’s what that feels like in real-world use:
- 30,000–40,000 BTUs
• Light warmth
• Best for mild evenings
• Ideal for ambiance and close seating - 40,000–50,000 BTUs
• Moderate, comfortable warmth
• Common for patios and seating groups
• Feels warm within ~3–5 feet - 50,000–65,000 BTUs
• Strongest heat output for propane fire pits
• Best for cooler nights
• Noticeable warmth within ~4–6 feet
Heat is most noticeable for those seated closest to the flame.
What Affects How Warm It Feels?
Several factors influence perceived heat:
- Seating distance – closer seating = more warmth
- Wind – wind disperses heat quickly
- Fire pit size & flame height
- Outdoor temperature
- Use of accessories, such as glass wind guards
A glass wind guard can significantly improve heat retention by stabilizing the flame.
Are Propane Fire Pits Good for Cold Weather?
Propane fire pits are best suited for:
- Cool spring and fall evenings
- Mild winter nights (depending on wind)
They are not intended to replace patio heaters or indoor heating, but many users find them comfortable for social gatherings in cooler weather when layered clothing is worn.
Ambiance vs. Heat
Most buyers choose propane fire pits because they offer:
- Warmth you can feel nearby
- A visible, inviting flame
- Instant on/off convenience
- Clean-burning operation
They are ideal for creating a cozy atmosphere, not for heating large outdoor areas.
Can I use my propane fire pit in winter?
Many propane fire pits can be used in cooler weather. Cold temperatures may reduce propane efficiency, and wind or snow can impact performance. Keeping burners clear is important.
Does cold weather affect propane tanks?
Yes. Cold temperatures can reduce propane pressure, which may affect flame height or ignition. This is normal for propane fuel.
Electrical & Ignition
Do propane fire pits require electricity?
Most propane fire pits do not require electricity. Many use battery-powered or manual ignition systems.
What type of ignition systems are common?
- Push-button spark ignition
- Battery-powered electronic ignition
Ignition type varies by model.
How loud is a propane fire pit?
Propane fire pits are generally quiet. A soft hissing sound from gas flow is normal.
Longevity & Storage
How long do propane fire pits typically last?
Longevity depends on materials, exposure, maintenance, and frequency of use. Covers and routine inspections can help extend lifespan.
Do propane fire pits require annual inspections?
Not always required, but periodic inspection of hoses, valves, and burners is recommended.
Can insects or debris clog the burner?
Yes. Spiders, insects, and debris can block burner ports. Covering the fire pit when not in use helps prevent this.
Is it safe to store a propane tank inside the fire pit?
Only if the fire pit is specifically designed with a ventilated tank compartment.
Accessories & Protection
Why should I purchase a stainless steel lid?
A stainless steel lid helps:
- Keep debris, insects, and moisture out
- Protect internal components
- Reduce maintenance needs
- Preserve appearance over time
It’s a simple accessory that helps protect your investment.
Is a propane fire pit actually safe?
Yes, when used outdoors with proper placement and ventilation. Propane fire pits provide controlled flames, do not produce sparks or embers, and can be shut off instantly.
Is setup complicated?
Most propane fire pits are designed for straightforward setup and do not require professional installation.
How often will I need to refill the tank?
Most users get multiple evenings of use per tank, depending on flame setting and BTU output.
Is there ongoing maintenance?
Maintenance is minimal and typically involves cleaning, inspections, and covering when not in use.
