Automatic switching on — the shutdown of the column will allow you not to use matches, because it integrates a special pieza element, which turns on the fire itself, under the influence of water pressure. There are heating columns where gas burning for arson is always supported. But personally, I do not like such columns, I am for those that are more economical and with piezen, in it, if the flame goes out, then only for some reason and automatically the gas will stop entering the column, which is very important in relation to the fire. Explosion of security.
