Grant Boilers Guide

Hi Guys,

I have a Grant Minor oile boiler model one S. I use it for central heating and it is pretty old- purchased in late ’90s. Last week it showed a red light on the control box, no central heating provided since then. After restarting burner goes for very short time (4-6 sec) and then boiler locks out. Red lamp pops up again. I am afraid of restarting it many times so I would be grateful if someone would tell me what may be wrong?

Thanks

Harry

Hi Harry

Is your boiler equipped with Riello burner?  If yes then then it may be pre-setting issue and you will need to use a manual for correct burner setting. However if your burner is so old I would rather vote for dirty filer, it is located in the supply pipe and has a glass on it- that should be removed for cleaning. If you see that the whole burner is pretty dirty you may need to take the whole burner out and clean it. I think it will help.
