How hot does a gas fireplace flue get?
A gas-burning fireplace tends to burn at a lower temperature, around 1000 degrees. Gas-burning is more efficient, so the grates and walls of the firebox can reach 1000 degrees as well.
What temperature should my flue be?
A good rule of thumb is to get the temperature up to a stovepipe thermometer reading of 450 degrees F. for the first half-hour, and to keep it at an average of 300 degrees thereafter, each day that you start your stove.
How hot does a flue liner get?
In normal operation a flue pipe will be at 150 to 250 degrees centigrade but can go a lot higher. If deposits attached to the inside of a flue catch fire then a flue pipe can even glow red (worst case scenario and extremely rare).
What temperature does a gas fire get to?
Flame temperatures of common gases and fuels
| Gas / Fuels | Flame temperature |
|---|---|
| Acetylene in air | 2550 °C 4622 °F |
| Methane (natural gas) in air | 1950 °C 3542 °F |
| Hydrogen in air | 2111 °C 3831 °F |
| Propane with oxygen | 2800 °C 5072 °F |
Are gas fireplaces hot to the touch?
The fixed fireplace glass on a gas unit can quickly heat up and retain heat for up to 45 minutes after it’s been turned off. The glass can reach extremely high temperatures and could cause a burn, so it’s extremely important to keep an eye on pets and children around fireplace glass.
What temp is chimney fire?
Once a chimney fire is going, it can burn up to 2000 degrees F, which is hot enough to break and crack clay flue tiles and melt metal flue liners in mere moments. That’s why a small chimney fire can become a house fire in very little time.
How hot does a double wall flue get?
These pipes only need a 2-inch clearance to combustibles because they remain cool on the outside, while their internal design allows them to withstand temperatures as high as 1,700 or 2,100 degrees Fahrenheit for a limited time.
What temp does natural gas ignite?
A much higher temperature is needed to ignite gas dependably. The temperature necessary is slightly higher for natural gas than for manufactured gases, but for safety with manufactured gases, a temperature of about 1200°F (649°C) is needed, and for natural gas, a temperature of about 1400°F (760°C) is needed.
Do gas fireplaces always give off heat?
A gas fireplace only produces heat when it’s on and the flames are burning, meaning that a gas fireplace can’t produce heat for your home when it has been turned off. Gas fireplaces aren’t always used primarily for heating purposes.
Can you put drywall around a gas fireplace?
It would be best if you did not use regular drywall around a fireplace as it is considered to be highly flammable. Instead, it would be best to surround the fireplace area with non-combustible materials such as stone, tile, marble, or metal.
Can a gas fireplace get too hot?
If the wrong logs are used, they can cause the temperature to shoot up. Another reason is the installation problem. The walls will get too hot if they are wrongly installed.
Can a gas fireplace cause a chimney fire?
It is fueled by gas and is often mistaken for wood because the fire looks very much like a wood-burning fire and lets out about the same amount of heat. Vented gas logs generate some soot and carbon just like wood-burning fires and can leave deposits in the chimney the same way.
