A bit of advice please. I have a Grant vortex eco 26 oil fired boiler with a riello RDB 2.2 burner on a gravity fed system. If it hasn't been used for a day or two, when it tries to fire up the fan starts and a few seconds later you can hear it attempt to fire, this lasts for a second or 2 and it stops firing but the fan continues. A few seconds later it tries again, lasting a fraction longer but then stops, then a few seconds later it tries again. Each attempt lasts a bit longer and the fan goes continually. After anything up to 15 attempts it seems to be working and condensate starts to appear and slightly warm air comes from the flue, this can take 5 minutes or more. Once it has been running it seems to start straight away when heat called for. Is it normal for Grant boilers to start like this? It is less than a year old and the installers have been back a couple of times, the last time "cleaned a thermo-couple" , but when they have tested it and it has "warmed up" it works correctly until it is left off for a day or 2. They are due back again this week but I have little hope of a fix.
Thank you.
