The simplicity and ease of use of gas furnaces was appreciated by many users. Thanks to the stove, it’s easy to cook the most difficult dish. But sometimes users notice that during operation it stinks of gas from the stove - the smell can be felt during operation of the burners, oven or after turning off the device. But what is its appearance connected with and evidence of what it is?

In this article, we will look at why gas leaks occur, and talk about how to troubleshoot on your own. We will provide the presented material with visual photos and thematic videos.

Features of the operation of the gas stove

Professionals know that the gas that is supplied in centralized lines is odorless. An unpleasant aroma is given to him with the help of odorant ethyl mercaptan. This is done for security purposes, as it allows any user in a timely manner detect leak, and, as a result, avoid poisoning or explosion.

At the moment when gas is ignited in a burner or oven, a small part of the fuel can enter the room, creating a feeling of leakage. However, this situation is safe, and the smell quickly disappears.

If the unpleasant aroma is constantly felt during cooking, you should think about the likelihood of depressurization of the system, the need for repairs.

Self diagnosis
It is worthwhile to engage in an independent search for gas leaks, restore the system’s working capacity only if you have specialized knowledge and experience in servicing gas appliances

Sometimes users do not understand why when a burner or oven burns and at the same time it smells of gas.

In this case, the cause of the leak may be:

  • loosening the attachment of the connecting hoses;
  • the presence of deformation, cracks in the gaskets;
  • the appearance of holes in hose in the process of prolonged use;
  • loosening the gas tap;
  • drying of the lubricant;
  • wrong plate mounting.

Before raising the alarm, it is worthwhile to figure out whether the gas really smells. For example, manufacturers treat the burners with a special composition, so when you use a new gas stove, you often feel an unpleasant odor. It appears when grease burns out. After a couple of weeks of operation, the smell disappears without outside interference.

Sometimes the cause of unpleasant aromas that appear during the operation of the gas stove is the carelessness of the installers. They leave pieces of paper, rags, plastic in the interior of the device. Under the influence of high temperature, the material gradually burns out, exuding an uncharacteristic aroma.
