What purpose is the vent hood on a gas boiler? A draft hood cools the air as it is released by the burners from 500 degrees F to between 300 degrees F and 350 degrees F. The cooling needs to be carefully calibrated to avoid condensation build up in the chimney however – a problem that occurs when the temperature gets too low.
What is the purpose of the vent on a gas furnace? Vent systems are an important component of the combustion process of a gas furnace. A venting system ensures that the hazardous gasses are removed from the heat exchangers and burners at the end of a heating cycle. If your furnace is not turning on, the source of the problem may be a damaged vent.
What does a water heater vent hood do? The hood sits on legs at the top of the water heater where the combustion gases exit the tank. It connects to the vent that carries the exhaust out of the house. The openings under the draft hood allow ambient air to be drawn into the vent to relieve pressure at the burner.
Can a gas water heater be vented out the side of the house? Power-vented natural gas water heaters use an electric fan or blower to push or pull combustion gases to the outdoors. This type of venting allows gas water heaters to be installed as far as 40 feet away from an outside wall and in homes without existing vertical vents.

Can you start a house fire by boiling water?
What About Boiling Water? Boiling water doesn’t start fires. Water boils at around 100 degrees Celsius or 212 degrees Fahrenheit. There’s not much that has an auto-ignition point below this temperature (and as boiling water has no flame, only the heat from the water could cause a fire).

Since cold air contains less water than warm air, relative humidity will increase until the air is saturated.
How can you separate two liquids with different boiling points?
Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling points.

Intermolecular forces (IMFs) can be used to predict relative boiling points. The stronger the IMFs, the lower the vapor pressure of the substance and the higher the boiling point. Therefore, we can compare the relative strengths of the IMFs of the compounds to predict their relative boiling points.
