I have just installed a Truma space hearted in my Jayco van and am concerned that dust might get into the system as the cowl cover is no longer available from Truma, just wanted to know if anyone has had dust problems that have caused system failure as Truma claims they are not necessary.

Hi
We built a plywood box around the heater so as to put things on top of it and to protect the unit .Best to leave a gap around it to allow air flow .

Timber boxes around/over heaters can be a recipe for disaster - manufacture an aluminium cover. - easily bent and pop-riveted.

Hi
I have boxed the unit in but my concern is dust entering the gas cowl mounted on the outside of the van I have installed a mud flap to protect it from stones etc. but dust may be a problem n unmade roads.

It is located just below the outside wall in a specially designed metal protective duct the same as Jayco use on their Silverline

09:18 AM May 13, 2021
Still not sure, out the side?.
When mine was installed they insisted it needed to go out the side wall of the van.
I wanted out the floor. Would not do for various reasons. But water and dirt were two of them.

My flue passes through the outer floor and into a metal protective duct which is dust and water proof. The cowl is fitted to the front of duct flush with the outside wall. My only concern is dust entering the flue via the cowl, Truma used to supply a cover but they are no longer available.

have you tried a 100 mm pvc pipe cap from Bunnings
Bob
Luvtravelling said
06:32 PM May 15, 2021
No I havent Bob I am just trying to find out whether it is necessary or not. Truma don,t seem to think it is so I might just leave it open, the problem with a cap is that if you forget to take it off the unit will backfire and possibly cause damage.

I have the same heater Noel, nearly 7 years old now. I have the cap and if left on when you want to use the heater, the heater will start but cuts off within a minute, it is a safety thing.
Great heater.

From my perspective as a licensed plumber that explanation is totally BS. This from the installation Manual. I am not being critical here, just stating what I believe to be the truth.
Exhaust duct With the Trumatic E 2400 (Australia) only use the Truma exhaust duct AA 24 (part no. 39420-00) with wall cowl and the combustion air supply duct ZR 24 (part no. 39440-00) for the installation, as the appliance has only been tested and approved with these ducts.
You see if that is still part of the manual on your heater it is a requirement of the manufacturer
It is part of its fitting and permit into Australia.
The fact that they no longer have it available is a separate issue and in no way discharges them from their responsibility of correct flueing. The air-in, and the exhaust pipe are made of one tube within another tube.They both terminate at the wall. and dust will certainly get into the workings over time in very dusty conditions.
Some arbitrary claim from a bloke who has had no problems is not going to help you if dust gets into yours.
Thems the facts as I know them to be....They can be mitigated only if they have it on the say so of the Australian licensing permit authorities. The reason most companies push diesel heaters its that any one with a spanner can install them. Gas heaters come under licensed plumbing regs.
I would say you have been give a story to match the suppliers non availability of parts. But I might be wrong and you need to go further with questions or take the initiative and fit a cover. Even fitting a self made cover, though seemingly ok is wrong in the eyes of the law.
An incorrect cove might let exhaust gas back down the inlet pipe and ruin a heater parts. Man have lit the thing with the cover on and it simply stalls. A home made one may let it run to destruction. But this is not know to me as I have no info on their demise.Most likely the thing would stop automatically with out fresh air.
It is a common thing that Truma make covers for their Hot water systems as well to prevent dust whilst traveling.
Any way food for thought, all the best with it.

Noel I do have a cover on mine , but I am up north for winter so the heater does not get a lot of use. It is only ever used a couple time a year on the way up , the rest of the time the cover remains on, I prefer this as I do travel the road less travelled and worry about dust, insect nests etc I have tried to start it with the cover on a couple of times ,but it just come up as a fault and will not fire up Never had the big bang, as it just goes to fault and has to be reset

Thanks Bob I think I will find something to cover it as not only dust but wasps spiders etc. may choose to nest in the flu and would be difficult to clear without removing the flue and reinstalling it with new O rings, which are only available from Truma.
100mm pvc cap sounds like it might do the job.

Noel there is chance the heater will start with the cap on. Thats why the Truma supplied cap is not PVC. It's heat/ ignition proof.
Have you tried caravan wreckers or Truma overseas.

That's what I'm thinking. Dirt and bugs.
I was told there was an incident relating to it starting with cap on. But as its an intake as well as an exhaust dont know how that could happen.

My Truma gas heater has a Truma supplied plastic dust cap
screw to a metal cowl I have only ever seen plastic caps
As I mention before mine will not start with the cover on ,
the cap seals itself against the wall and no air or exhaust can get in or out
wont light without air

I had installed gas heater with exhaust out under van , that was no good as exhaust didnt move away and stayed around outlet i was getting error messages . I phoned truma who advised need to get outlet to side of van where there is natural air flow/movement , problem solved .
oldbloke said
11:01 AM Jun 16, 2021
So, I measures the outlet yesterday. It's 95mm. So 100mm cap was way too big.
Bit of an odd size. My van is now in storage till it warms up a bit so I just taped it up in the interim.
