Carver Trumatic Sb1800 Issue


Recommended Posts

Hi there, new member here and new to caravanning in general so bear with me!

 

Just become the proud owner of a 1991 Swift Corvette (4 berth). It is fitted with a Carver trumatic SB1800 gas fire.

 

We dont have an operating manual for it, so have no idea how it works - I turned the knob round to the middle, pressed it down and then pushed the ignitor down, and it seemed to light ok, and you can see a yellow-ish flame in the viewing window at the bottom. (should this not be blue?)

 

Turning the knob round much in either direction kills the flame, and the heater itself doesnt seem to put out much heat at all, even after being left on for half an hour or so.

 

Im probably being thick, but if anyone has this model of fire, what am I doing wrong???

 

Realistically I think we will mostly be using an electric convector heater on site, but it would be nice to know the gas fire worked if we ever needed it.

 

Cheers

 

Mike

It needs servicing ASAP.

 

Do not use it as you could be taken ill very quickly.

 

The yellow flame is bad news. It must be BLUE to be safe.

 

Is the Cooker OK?

 

 

 

 

Don't want to scare you but this is on Google.

The flame should indeed be blue, lanky looking yellow flame means there is something blocking the burner/s, usual culprit is a spider bedding down for the winter?!.

Beyond the need to sort that out, the major problem with these 1800 series fires is corroded steel pipes feeding the heater and back down to the burner. They will look as new inside the van but a different story underneath, these need replacing if any sign of pitting of the surface of the pipes.

 

So in short it needs a proper service

I would imagine then given the age of my van its quite likely the pipes underneath will need replacing then!

 

where I have parked the caravan, it is tight against a wall on the heater side so without moving it somewhere else I imagine they will be tricky to replace?

It should be possible to work on the whole heater from inside the van I think.

 

The pipe run underneath is a different problem. It may be accessible from the end of the van if it is tipped up.

I guess I could jack the front of the van up a bit, throw some axle stands under and get at it that way. ....

 

Arc systems - I have seen from other posts you supply the pipework required?

 

Friends of ours have replaced the gas fire with an electric one, half tempted to do the same myself as with kids in the van it would be a safer bet and just keep the gas for cooking

Lets get one thing straight about the safety aspect, when this fire is working correctly, it does not produce any CO, well not quite none but the highest reading I've recorded, not at the side where it should be taken but inside the exhaust itself, was 4ppm, you get a darn sight more than that while smoking per puff!!.

 

Regards servicing, the fire has to come out, it's impossible to do correctly in-situ, further it needs doing by someone who knows what he's doing. it is not a DIY job.

Cheers, kinda puts my mind at rest a bit re the co2! as you can tell im pretty ignorant about gas in general.

 

I know the fire has to come out to service it, I was just looking a short cut at getting to the pipes under the van without having to move the whole van - like I said jacking it at the front and supporting it properly on axle stands etc and getting under from the front.

 

I am pretty competant with the DIY / mechanics etc but dont worry I have no illusions about working with gas, if we arent going to replace it with an electric heater I had intended replacing the pipework myself, having the gas fire professionally serviced then having the whole thing pressure tested after reinstalling it.

Just a thought - it was pretty cold the other night when I tried the gas fire, and we have a blue (butane?) cylinder in our van - I seem to remember reading somewhere it doesnt burn well under 5 degrees, is this correct or am I clutching at straws?

It would have some bearing but you said the hobs worked OK?

 

Change to Propane and forget Butane unless you only use the van when the weather is warm.

 

Butame maybe cheaper but it is no use in winter. Some use it but wrap the cylinders to keep out the cold.

Havent had a chance to try the hob yet, I think ill try everything during the day at the weekend when it should be a touch warmer!

 

It was pretty cold the night I tried it, later that night heavy frost was forming on the caravan roof so im hopeful thats what it is? If so I feel a bit daft!

I took out a propane cylinder in April many years ago and put a butane on the van. At 7. 00 in the morning there was a white frost on the field. The gas would not light to make a morning cuppa. I had to drive 10 miles home to fetch the Propane still in the garage. From that day I never used Butane again. ............. 22 years ago.

If it turns out its just due to the gas temperature, ill just use the butane up (theres at least half a cylinder left) and change to propane at that point!

 

Oh and ARC systems, cheers for the tip on the pipework under the van, ill check the condition of it before I do anything!!

Butane freezes or more correctly, it actually stops boiling into a gas at -2c, the act of evaporation though creates cold and this further lowers the bottle temperature, hence it is not wise to rely on it below about +5C, but that's not to say it won't work?

It's the amount of extra cold it creates and this depends on how much gas you are demanding, I would, considering the1800 at 1. 6kw does not want a lot, still expect it to work.

I use it in short burst for testing throughout the year and it's not let me down yet.

Well I was off yesterday afternoon, and as it was showing 12c outside I thought I would have another go

 

Turned the gas on, and the fire lit first try, and showed a blue flame. Also within ten minutes or so the caravan was roasting, plenty of heat coming off it.

 

Had a look under the van, and as far as I can see the pipes are all copper but Ill get a good look this weekend.

 

The pipe from the gas mounted regulator to the copper is black and looks a bit old (i. e. hardened and a bit cracked looking where it joins the regulator) so I will be having that replaced.

 

When the fire was running there was a hint of a gas smell outside the van, could this be from the flue? where it is sited, its tight against a garage wall on one side, a wall at the front and barely a metre from the house wall on the other side so I cant imagine airflow under the van would be great.

 

And last but not least theres an odd smell off the heater, a bit like what you would get from an electric heater with dusty elements?

 

In summary, does anyone know a decent mobile gas engineer near Belfast to at least get a pressure test done?

If you have a cracked supply pipe I would expect a gas smell as well. They have dates on new pipes and need changing after a few years.

 

A pressure test is needed of course because it is all un-tested.

 

It may well have been Butane that gave you the initial problem after all.

 

It is always worth a leak test in any van. I have a friend who had 6 separate leaks in a new van. :blink:

The thing about butane is if it was too cold, any flame would be oxygen rich, so a smaller and more blue flame, yellow as it was, denotes a gas rich flame so not at all sure why unless the blockage cleared itself?

 

The offending steel gas pipes are part of the heater and lead up from the vans copper pipework up to the fires gas valve and a thinner one back from the valve to the burner.

You should not smell gas at any time but fumes might just linger if air flow under the van is blocked by the wall, but and as I said, fumes of any sort are so small in quantity, I would really not expect anything enough to smell?

 

Inside it would as you guessed be dust burning off the top of the heat exchanger, this is common after long periods with no use, this then taken together with the smell of 'gas' and a very old and cracked rubber gas pipe, tells me, the whole system is well overdue a thorough service

This topic is a good place to add a reminder about gas safety.

 

I am sure it will be useful information for others with similar problems to yours.

Will do, probably best to let the engineer swap the hose and then test everything! We go away for the first time in April so I'll get it done before then.

 

We bought a mini oil filled radiator today (amongst lots of other things for the caravan!) which seems to put out a fair bit of heat and isn't too heavy but I'd like to have the option of the gas but only with the knowledge our system is safe

 

Cheers for the help guys. I'll update re the state of the pipes to the heater when I get a proper look, might end up needing those done at the same time

Why do the carver heaters have a steel pipe, can it not be replaced by a length of copper 1/4” pipe?
