Using an Integer Expression to perform a Floating Point calculation
The objective of this 'C' tutorial is to show how a floating point operation can perform much faster by using integer arithmetic. The principle is based upon decimal to fraction number conversion, in which a specified literal floating point constant, is converted into an integer fraction.

This describes how to dismantle the gas heating components, and how I resolved the problem I had on my water heater. I had a intermittent problem of the gas igniting ok, but then the gas switched off after an 8 second timeout, and the red Error light on the switch would glow.
Excellent video. Thanks.
Thank you sir ,it was really useful, two weeks ago i brought a caravan and i have no idea what it is , there was not any wiring and instruction. thanks for sharing...
Hi Brian great video very helpful ,i have one of these that is leaking water (external) from the nut looking thing in the middle of the heat exchanger fins (center of) any ideas.thanks
Amazing thanks for the help
What an excellent presentation! We have a caraver rapide., and your video has been so very educational. Please tell your family that you are appreciated and doing a marvellous job. Regards from New Zealand.
thank you it is a valuable information
Thank you.. great help!!
Thank you Brian, very informative and covers the points needed 👍
I had the same problem. It was caused by corrosion deposits from the alloy casing covering the burner. Cleaned them out and rubbed down the casing and sprayed with stove black paint. The screws for the stainless panel behind the burner sheared off on removal. I fitted a jubilee clip on the drain plug pipe to keep the panel secure.
I can confirm, this worked for me! Pull it out, give it a good clean 😊
excellent instructional video thank you for recording and posting. I now have complete confidence to troubleshoot and recondition my Cascade 2 . Thank you very much
Nice fix Brian.
Many thanks found the problem with mine .. it was an internal glass fuse gone in the igniter unit great video 👍
cool thanks for that
Thank you very much for this. ❤🎉
A well explained video and having the electrical side explained helped . excellent narration ..well done
Hi, Brian, I have the same problem with the boiler. works 5-10 sec. and stops. I will try your way. There is a video here. czcams.com/video/_Mv1SRkVJYY/video.html Thanks
Excellent even from a gas engineer
My burner has become very noisy and I'm convinced the burner needs a good clean. Now I know how to to do it. Great video thanks
Very helpful thanks for time
Fantastic video explaining everything clearly. Great job.
After 22 years my burner is very rusty and flaky - this post has give me the confidence to replace the burner - thanks for posting
Wow. I’m surprised I haven’t seen this video before as I’ve had to fix my Cascade a couple of times for other reasons. Really well presented and it’s nice to see someone including technical explanations whilst keeping the ‘how to’ aspects simple. Good Stuff.
I have this same Water Heater, but for some reason no lights come on the control panel at all, either when Leisure battery or hooked up to the mains, My Volt meter confirmed that power from the Leisure battery was getting to the panel, but still not lights, cant work out what i am missing
We have a 1980s Mercedes 207d motorhome we have used the shower with hot water via the 12v battery worked well now wanting to use it on gas to heat water for showering I turned the gas on then I put the switch on inside the van then put the carver switch on which stayed on green left it on for 45minutes tried Water freezing cold so then left it for 4 hours tank is full of water by the way still cold my unit outside is sealed up around the edges so I need to cut the old seal off unscrew the screws and have a look inside as I can’t really see inside with out taking off the front cover hoping your video will help me sort this issue out as it will be much easier heating water on the gas bottle while we wild camp any advice would be great
Very informative. Many thanks.
Very well explained and clear video. Very clever guy. Thank you.
Had same issue. Took apart cleaned and test running like a dream. Many thanks for your video
Thank you for this detailed video!! I was looking on how to remove the burner and this answered all my questions. Much appreciated!!!
I have an Abbey Oxford only on gas, no 2eg electric boiler. I am from Romania. I have all I need, even the leak is fixed from the tank, I have flame, but no hot water. I think this is the same problem you have, since its 1989 built. Thank you I will try to clean it too !
This vid deserves a little more credit than it seems to have received. I have wrestled with putting small neural networks on embedded systems and this very detailed and concise video has affirmed some of my findings and benchmarks. Kudos for taking the time to create this vid.
Cheers for this!
on my spark electrode the porcelain is cracked and broken, will it still work?
It may do, but not all the time. If the ceramic housing is cracked the spark may track to elsewhere, we repair and service the Cascade burner modules and we see a lot of units come to us and the reason for not working is cracked ceramic housings. Also flame detection problems as described.
can i buy a new one anywhere
peter collins We do sell refurbished ones but it's cheaper to get the one you have repaired. You can find us at www.arelectronics.co.uk We offer a repair service and full testing of the module with 12 months warranty.
Thanks great help .
Worked a treat. Thanks again
Brian, Thanks so much for that. I am having the same problem. as i live in New Zealand and own an otherwise excellent English caravan I have been at a loss. i have asked various 'van sales and repair firms here on how to rectify this annoying problem. not surprisingly they are all reluctant to share the process you have described. they of course either want to do the job themselves or sell me a brand new module at a king's ransom price. You have helped enormously. Cheers, Roger T. (one grateful Kiwi)
Very clear and detailed. Thank you.
I done the same, Thanks Brian. I do have a problem though... Instead of shutting off,, the burner stays on for a minute, then shuts off for around 1.5 mins, then starts up again, This continues in this manner, not heating the water. Left in this mode for 2 hours, water not even luke warm, Any ideas ?
More than likely you have a draft that is blowing the heat onto the thermistor and is getting too hot, then shutting off. If this isn't the case then the thermistor housing may be crooked and picking up heat from the flame. If it was a flame detection problem it would shut off between 7-10 seconds.
Just fixed my son's Water heater. Many thanks: It gave us the confidence to try it.
Thank you very much for this video. It will help me to solve a similar problem on my son's Camper
many thanks for sharing. we have a 1991 caravan and the water heater didnt work and was just to pricey to replace followed your steps and hey presto we now have hot water.
Truma geht immer aus
Just fixed mine,water in the plastic tray under the pcp board. The solder seems to have been jutting down under the board a touch the water ,also the plastic enclosure was being clamped by the heater casting,so clamping the plastic enclosure. just filed the casting now able to withdraw the unit from the side,and no clamping problems on the electronics. Every thing now works,this video was a great help. Many thanks.
Excellent Video and well explained. Thank you Brian, Regards Adrian
Thanks Brian your video was really helpful. Mark
Brian, I haven't fixed my cascade yet but am convinced you've just shown me how to do it. Many thanks for posting this very helpful video.
Brian, I feel I owe you a beer, send me some details, and I will in receipt send you some. I have spent many an hour trying to measure the rectification element created by the flame, cleaning the burner, and even cleaning out the jet, without ever having removing the jet. Removing the jet uncovered debris, and loosening the burner unit so I could adjust the distance between the jet and the orifice on the burner has just saved me a small fortune. I really didn't realise the jet could be separated! Thank you so much.
Really good, thanks
great help thanks alot :)
I have a problem with actually removing the assembly, the bit that occurs at approx 2mins 25secs into the video.Its loose but the box inside seems to big to come through the hole. Any suggestions
It may be the lid of the plastic box that holds the PCB. If the lid was not properly closed, it may be catching on the top of the housing. The lid is hinged on the left side of the box, maybe you can slid something thin between the lid and the housing to push the lid down, as you pull the unit out.
