In need of advice on Rayburn flue system.

[Plucky]

Called out to a customer with an old rayburn.

They had reported smell of fumes coming from stairwell, which is nect to the chimney. On inspection via hatch in register plate this is what I found.






What is my best course of action?

The appliance is running on Oil. I dont know whether the seal from the bit you can see has fallen out or something?

The flue external diameter is 5.75" and cast iron so a 5" liner would drop down but I am unsure of flue fittings t use to make the connections to the starter section from the boiler and the terminal etc for the top.

The chimney is also serving an 2 open fires so would need to take that into consideration when terminating at the top.

Work would be undertaken with OFTEC engineer but he only does servicing hence him bringing me on on the job.

Any advice greatly recieved.

I am not an oil engineer but if this was gas it'd be upsie down. I'd assume it to be the case for oil too? You are looking up the chimney yeh?

i agree flues upside down,if you were using a flue liner(can you use single wall liner on oil?)you would be either replacing the section down to the rayburn in 5" il using a kopex to il adaptor ,and a draft hood connector on the appliance or using enamel with a liner connector

The flue pipe is upside down,even the connection off the top of the flue box of the cooker is,it's surprising how often it's done that way,but as in the chimney,fire cement falls out and then condensation can run down the pipe too.

As you say a 5'' liner would be fine,there are plenty of fittings available to adapt to a cowl at the top(I prefer the vedette). I would replace the cast iron connecting to the Rayburn too.There should be a 600mm straight piece before any bends(which mustn't be more than 135degrees)There are adaptors to connect 5"enamelled pipe to flue liners.

That looks like a Rayburn Royal M/F to me,it was originally a solid fuel cooker and has been converted to oil,the flue temperature isn't high enough to require a class 1 flue liner so a class 2(single skin)would be fine.
