It is recommended to use strips of corrugated paper to check (whether they move or not). But the fire of a lighter or candle can be dangerous, especially if there are problems with fuel leakage.
When is it time to clean your gas water heater?
The following signs indicate that your gas water heater needs cleaning:
the heater starts up, but does not work for long, the main burner quickly switches off;
from below, soot begins to pour out from under the casing;
The unit operates at maximum power, but the water barely heats up.
A pop in the combustion chamber indicates that a large amount of rcs data has accumulated in it before ignition. This means that the problem is in the pilot light, which ignites the fuel late. A visual sign is a weak flame of the wick, painted yellow, which is a sign of a clogged jet. The solution to the problem is to clean the pilot light. In most models of water heaters, the ignition unit can be easily disconnected from the main burner and remove debris from the jet.
The overheating and draft sensors are triggered by soot accumulated between the heat exchanger fins. The cross-section of the gas-air tract is significantly reduced, and the water temperature increases. In this case, it is necessary to clean the radiator and combustion chamber walls from soot. The extreme degree of contamination is when soot flakes fall from under the decorative steel apron, covering the floor or objects under the heater.
Weak heating of running water is a consequence of the reduction of the flow cross-section of the heat exchanger pipes, whose internal walls are covered with a thick layer of scale. A sign of total "overgrowth" of the internal passage of the tubes is a noticeable decrease in water pressure at the outlet of the column with its normal pressure at the inlet. These are salts contained in tap water, intensively precipitate on the heated surfaces of the pipes and form a strong thick coating. Then the gas water heaters, or more precisely, heat exchangers, are cleaned from scale by flushing.
