We inherited a bar height outdoor table with a propane fire pit in the middle of the top. it lights, but the flame is really low, and we cannot put lava rocks and/or logs on it or the flames will be non-existent! suggestions? We made sure the holes are clear and blew air through just to make sure there was nothing blocking anywhere. Other propane fire pits i’ve seen have great flames that look quite similar to a real fire…ours….not so much :o) Please help! we’d love to be sitting out of our back deck enjoying the fire with the cooler weather!

Dropping flame height is typically a cold weather problem for gas fire pits that use propane as their fuel source. It is caused by the inability of the gas in the tank to vaporize at sufficient speed to fuel the flames.
Check the gas line connecting the burner to the gas connection inside the fireplace if applicable. If it is a flexible line, ensure no kinks exist in the line. Kinks could decrease the amount of gas to the burners and limit the size of the flames. Straighten the line if necessary.
Yes there is a way to get more fire and heat from a fire pit. Drill the valve out and the burner holes. I would do these in small increments because you don`t need much more and dont want to drill it out too much and have a huge flame.
Problem: Low Flame, Low Temperature
This is a common problem with many grills and is almost always because of the fuel line regulator (the UFO-shaped thing on the gas hose near the fuel tank). Regulators tend to be sticky. When they stick, they limit the amount of gas and will not generate a good grilling temperature.
Propane requires a higher pressure than natural gas. The ideal pressure for propane gas is between 7” WC and 11” WC. If you have a whole-house propane tank, you`ll want to install a regulator that delivers gas in this pressure range. The recommended gas pressure for PROPANE fire pits is 7” WC to 11” WC.
A healthy, properly burning flame on gas appliances should be blue in color, sometimes with a tiny tip of yellow, with a little light blue triangle at the center. This blue color flame indicates that there is safe, efficient and more complete fuel combustion.
When you use your propane gas cooktop, you should always see a blue flame. That`s good, because it`s normal. When the ratio of fuel to air is correct, there is enough oxygen for complete combustion of propane. Complete combustion results in a blue flame.
What Is a Regulator, and Do I Need One for My Gas Fire Pit? Yes! You need a gas regulator because it takes the high pressure in your gas line and reduces it to the pressure required by your gas appliance. Each appliance will have its own regulator because different appliances will likely have different requirements.
A weak flame is often a signal that the safety regulator on the propane line—that aluminum device that sits near the end of the hose that attaches to the tank—has been tripped, slowing the flow of gas to a trickle.
If your gas stove isn`t getting hot enough, it`s most likely due to a faulty gas supply, a misaligned gas burner cap, a blocked burner head, or a faulty control valve.
Excessive primary air can cause flames to lift and blow-off the burner ports. Any factor which reduces burning speed promotes lifting flames. Also, any factor which increases flow velocity from ports contributes to lifting flames. Overrating of burners is also a cause.
Generally, propane pressure should be between 100 and 200 psi to ensure that the liquid propane gas remains in a liquid state.
All flames on gas hobs should burn crisp blue. A weak yellow or orange flame should not be present. Dark or sooty staining around gas appliances including gas stoves and chimneys.
How to Make a Gas Fire Pit Flame Yellow. Quite simply, to make the flame in your gas fireplace or fire pit yellow, reduce the amount of air mixed with the gas.
Increasing the air flow to the burner produces more complete combustion and a hotter flame. The air is increased by opening up the air vent (turning the metal collar). The air is drawn into the barrel of the burner by the gas coming out of the gas jet.
Once the burner is lit, the cog in the base can be manipulated to control the height of the flame. The flame should be adjusted so that there is a clear blue flame surrounding an inner blue cone.
work on propane-air mixtures over wide ranges of equivalence ratio (Φ = 0.7–2.2) and initial temperature (Ti = 295–400 K) and pressure (Pi = 50–400 kPa) showed that the maximum laminar burning velocity found for propane is nearly 455 mm/s at Φ = 1.1 and the maximum explosion index, commonly called the `explosion …
The maximum neutral flame temperature of propane in oxygen is 2,822 °C (5,112 °F). Propane is cheaper than acetylene and easier to transport.
With complete combustion, an LPG (Propane) gas burns with a blue flame and burns at a temperature of around 1,980°C, as noted on the flame color temperature chart.
A fireplace blower pulls air in from the room and forces it through a channel on the fireplace`s exterior. As the air travels around the hot fireplace, it heats up, and by the time it is released into the room, the air is much warmer than the rest of the room.
Second Stage and 2 PSIG regulator vents in must be pointed down should be installed at least 12-18 inches above the ground. In some cases due to snow accumulation this distance may exceed 6 feet or more. This will help protect the regulator vent from rain, snow, sleet etc.
So, what`s the big deal? Well, the pressure within a tank of propane is anywhere between 100 and 250 psi. If that pressure were to be released without being regulated/controlled by a propane regulator, you`d quickly find yourself in a terribly dangerous situation with a huge, uncontrolled flame.
If your home gets too cold while there is minimal propane left in the tank, the gas will not expand as much. This results in a lower pressure which can cause your propane-based appliances not to operate efficiently or safely.
