We have now disconnected pipe at the tank and blown air to clear pipe. We have also cleaned the filter at the tank. We re-connected and then opened the valve until a constant flow of oil came through. We have now tried to re-start, but still not working. Are we missing something else?
thank you. We have just switched off the oil supply at the tap in the boiler and undone the connection. When opening the tap, no oil came out so we are presuming there is a blockage. Any ideas?
Please help. We ran out of oil yesterday and have a Mistral Combi Boiler Model 15/20. We have had a delivery of oil today, but I cannot re-start the boiler. Any ideas?
