How to clean the AOGV 11 automation unit

Good day.

Automation of the AOGV 11 boiler is unstable - the igniter is on (although quite weakly), but the main burner ignites every other time. In addition, the torch of the main burner does not develop full power. Previously, with the position of the controller “3”, the unit gave a temperature of 55-60 ° C, but now for this you have to twist the handle to the maximum. Tell me, is it possible to clean the automation yourself, as well as how and how they do it.

Answer

Hello.

In fact, maintenance and cleaning of gas equipment should only be carried out by qualified gas specialists. And if the question was about interference in the settings of the automation unit, then your appeal would have remained unanswered - as you know, gas is not worth joking. Nevertheless, we will tell you what needs to be done, because the symptoms described by you indicate a fairly common cause - clogging of the internal channels and AOGV 11 jets.

An unstable ignition of the burner is due to the fact that a too weak pilot flame cannot warm up the thermocouple, as a result of which the main gas supply valve remains closed. All that needs to be done is to clean the ignition device’s nozzle with a thin copper wire or a toothpick. Most likely, after this the problem will disappear.

As for the question why the boiler does not develop maximum power, this is often associated with the same banal blockage. The fact is that the boiler, which is idle in the summer, is a favorite haven of spiders that crawl into the internal channels and equip nests there. In order to eliminate the cause of the blockage, it is necessary to remove the gas burner block. After that, turn out and clean the fuel jet and burner channels. In most cases, these simple, effective measures have helped to cope with the problem of unstable operation of AOGV 11.
