How do I prevent my gas fridge jet from clogging up?

[RustyRuss]

I have a Dometic 3way fridge, I have had to clean/unblock the minuscule hole in the jet at least 3 times now. It’s a total PITA to dismantle the gas pipe, flue, ignition system etc. I have a Truma inline gas filter between the safefill gas bottles I use and the rest of the gas system, (cooker, central heating, fridge etc.) but I keep getting tiny black specs of debris stuck in the fridge jet. The filter has been in situ for about 4 years and I’ve run around 45kg of gas through it. Question is what is the source of the tiny black specs? And also how do I stop them appearing again? It’s infuriating!!

Cheers!

Buy better quality LPG!

If you have a refillable system, French Autogas is notorious for being filthy and oily.
Hence we never get LPG in France.

Also the butane/propane mix is altered the further north you go and the later in the season.
In northern europe in mid winter it should be mostly propane.
In southern Europe in summer it will be mostly butane

An expert will be along shortly, but I think propane tends to be cleaner.

Or, if you use calor bottles, get the red ones (propane).
Not the blue BBQ ones designed for summer use (Butane)

It’s probably the filter breaking down, take it off and don’t bother putting another one on… the less you have in a system the less to go wrong..

Have you changed the filter in 4 years? If it’s the latest black filter, Truma say the filter pad inside it should be changed every time the cylinder is changed or refilled. The previous silver filter should be checked for oily particles and the filter changed if necessary.

It could be specs of rust from the supply pipe to the fridge, we had this on our old caravan, I cracked the joint at the jet and got a proper little pile of rust, a magnet will tell you if it’s ferrous.

What great advice people! Thanks very much! Sorry I haven’t been paying attention but we’re getting Ofsted’d next week and it’s all hell and notion at the moment!

Cheers! Russ

When you do manage to spend some time on it Russ, come back and let us know how you got on please.

I have to say in 20 x years of using a bulk tank, then refillable cylinders, I've never had a gas filter installed, and never had a problem with low pressure or a blockage due to oily deposits. Maybe I've just been lucky, but on both setups, my regulator has been higher than the tank/cylinder outlets.

Cheers,

Jock.
