Trumatic S3002 heater query

[nuevo54]

Hello everyone,

I have query regarding the Trumatic S3002 space heater in my recently purchased 2004 Autosleepers Nuevo motorhome.

I was lighting the heater on gas at the weekend and for a few seconds it struggled to stay lit, and the flame blew out several times - probably due to some air in the gas pipe, which is not unexpected after a change of gas cylinder etc. After a couple of attempts it stayed lit and has been working fine since. However, I noticed after the first failed attempt that there was a brief smell of exhaust fumes from the heater, which I found a bit worrying. Since then, it has worked fine and I have not smelled anything amiss.

Should I be worried? I thought these heaters were sealed, so I don't understand how there can ever be any combustion smells. The van did have a full habitation service when I bought it three weeks ago (and I have fitted a brand new carbon monoxide alarm in the van!).

Thanks in advance.

Quick update... I tried the heater again today, and had the same problem with the flame constantly going out. I now realise the flame is going out due to the wind blowing back down the flue - it's pretty gusty out there today! I think the slight smell was probably due to a brief puff of exhaust gas blowing back out the air inlet.

I've now read that blowing out in the wind is a common problem, and can possibly be solved by fitting a Truma flue extension on the roof (now ordered). Hopefully this will sort the problem in future!

Great that you've got it sorted and well done for coming back and updating, so few do.
We had an S3002 in our caravan and, yes, we on occasions experienced similar issues.
