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.

    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 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

  • @powerbookg4apple
    @powerbookg4apple Před 4 lety

    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

    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 !

    on my spark electrode the porcelain is cracked and broken, will it still work?

    • @yansolty
      @yansolty Před 6 lety

      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.

    • @petercollins3333

    • @yansolty
      @yansolty Před 6 lety

      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.

    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)

  • @davehogg2420
    @davehogg2420 Před 7 lety

    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 ?

    • @yansolty
      @yansolty Před 6 lety

      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.

  • @johnevans7389
    @johnevans7389 Před 8 lety

    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.

  • @iandonnelly542
    @iandonnelly542 Před 8 lety

    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.

    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

    • @brianplummer3976
      @brianplummer3976 Před 9 lety

      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.
