I have an oil Rayburn Royal OF7 which has worked fine for years but over the last few days has started producing a bad smell of fumes in the hot oven. (The smell isn't an oil smell, I've spilt enough of that to know!). This only started since I did some work on the plastic storage tank (1200 litres). Previously it had only been supported on block pillars running length ways down each side of the tank but this left a large section of the tank unsupported so when it was filled a large bulge appeared at the bottom though this reduced as the tank emptied. To overcome this I've placed 4 pieces of 4”x 2” timber under the tank, running from side to side, which I did a few days ago after the tank ran dry to make it easier to man handle. I removed the top layer of blocks before fitting the timbers so the net effect on the tank is that it has been lowered by about 50mm. The smell has coincided with this work. Other things that have happened/checked over the last couple of weeks are:
• chimney swept/flue cleaned. I rechecked this a couple of days ago thinking maybe a lump of render or something had been dislodged when it was swept but I can clearly see the sky so no problem there
• burner serviced (by me as I have done every summer since the Rayburn was installed – 2nd hand) which included decarbonising the fuel pipe at the base of the burner and the area where the fuel comes up into the burner, fitting new wicks, checking the burner was level, and ensuring the all the metal perforated baskets and baffles were clean
• I have checked the oil flow rate at the regulator which is 4ml on the low setting and 15ml on high
• the fall on the tank is 85cm to the oil regulator
• tank filled, it was dry so 1200 litres went in
• I have bled the oil pipe
• New filter fitted at the tank
The flame is yellow so presumably is not burning correctly but I’m stuck on what to do next. I can’t see it being the new oil, I’ve used the same reputable supplier for many years now without any problems. Could it be that as there was a build up of swarf/gunge/sludge etc where the tank used to bulge and now by providing better support this has been dislodged and is floating around in the tank, though surely the filter would catch this?? Any ideas or suggestions?[/b]
