Halsted Ace High- hot water problem

[Chris H]

Heating works fine, hot water works fine for about 3-4 minutes then burner goes off and then re lights within 60-90 seconds? System pressure is fine, have adjusted the temperature control and still does the same thing regardless of water temp. Any ideas?

if your an rgi this is a fairly simple cure normally, if your not gas registered call in someone who is as youll have to be replacing control/safety devices and this comes under rules of gas safety.
