I have a sime 102 super de luxe, when heat or hot water turned on it fires up fully (flame a bit orange) then quits after a few seconds. After about half a minute it fires up again and then quits. Any idea whats causing this?
If your flame is orange,you need the boiler servicing asap,should be bright blue.Sounds like build up of gases is shutting your boiler down,ie products of combustion aren't being drawn out .
