problems fitting exhaust flue on new instalation

Post by Gary.pb »

I have recently bought a new Dometic RM 123 fridge to fit into my camper. Last year I put in a second hand interior which had space for a fridge which my van didn't have previously. I have trial fitted the fridge and the exhaust flue (which has no adjustment) would need to exit the van right on the part of the panel where it rebates in and out. I clearly cant put a vent here and I cant move the fridge higher or lower. Has anybody else experienced anything similar??? If so what did you do?? Is it possible to purchase some sort of flexible flue?

Any help would be gratefully received as I am a bit stumped on this one.

i and i think many others have a section of SS flexi, it can exit through the swaged area but it needs an adaptor making up etc

It's attached in the previous picture and the stiffness of the pipe holds it securely in place.

There's far too much exaggeration with regards to fridge gas exhaust, there's barely any and in the case of vans with vents as well as a flue it wouldn't matter if the pipe became detached as the air flow through the vents would easily disperse the virtually negligible exhaust gas.

1. Only the approved Dometic (formerly Electrolux) flue kit must
be used.
2. The flue top must be secured using the screw provided to avoid the
risk of restriction.
3. Allow 5mm clearance between the flue pipe and combustible material
in the wall of the Caravan/Campervan to avoid fire risk.
4. Provide a minimum of 10mm clearance between the end of the flue
pipe and the flue top to avoid distortion of the flue cover.
5. Fit the perforated flue cap to avoid dirt and moisture ingress and
to prevent accidental flame blowout.
6. Ensure that the gap between the flue cap and the inner surface of
the flue cover always exceeds 5mm to avoid the risk of restriction.
7. On the non-integrated flue system sealant should only be applied
between the outer flue cover and the flange plate of the flue tube at
the top and side only. It should not be applied behind the flue tube
flange plate.

no sealing tape please :tsk

had mine refitted last year and certified by a Gasafe engineer (at same time as Propex etc). Lots of measuring took place! The last thing to be fitted was (at his insistance) a heatproof sleeve around the top part of the exhaust, that connects to the outer flue. Having just taken a peek at it it still leaves a gap (ie: is not taped to...) at the lower end. Effectively it's a collar preventing any heat transfer to anything nearby. Pain in the a** when being done but glad all sorted now. That's all good info there Kev... :ok

I recon this is pretty much what I need to be doing, thanks a lot for that :ok

out of interest how did you get the flexible pipe out the van. Im assuming it is joined to a riged straight section just before it goes through the panel?

I will have a little look online tonight to see where I can order some flexi pipe.

I had almost decided that running the fridge on gas would be more hastle than its worth and that perhaps I should just run it off the leisure battery. Then I worked out how long the leisure battery would last before being flat and realised I was being a lazy git and should fit it properly :lol: :lol:

Blimey, the things we have to go through to ensure we have cold beer :wink:

Thanks for the info, much appreciated

Would something like this be suitable

To be honest I don't know how hot fridges run at.
The ad states that it is heat resistant but would that be sufficient or would I need something more substantial?
