This Video was taken during the testing of the boiler after parts are replaced, namely Fan & Gas valve.
this boiler was Classified as at risk by British Gas due to :
1. Fan not working
2. Gas valve not working
3.. External pump not working
Once I done further checks about the fan - APS - PCB - it was found that the 240 power is percent at the fan during the ignition sequence. Also during the dry test ( with Gas Off) it was noticed that the power to the gas valve is percent and I can hear a good clicking sound of the fan proving the valve is opening and closing.
I just replaced the Fan and open the capped gas meter - uncapped it and done a tightness check - guess what - 6mbar pressure drop on U6 meter ( this is ID by GSIUR) - shut the boiler gas isolator - retested it no pressure loss. Replaced the gas valve, replaced the pump everything is working.
BG should have ID the boiler and written about the gas leak - but instead they AR it and told the owner that they need to replace it at extra cost. ( this is probably why Advertising board banned their advert - Look After your world advert)
Need to recommission the boiler - cleaned the burner ( this property was closed for nearly a year and the owner just bought it) adjusted the burner pressure to match with the boiler size, gas rated it - still there is a yellow tip on the flame. Done a combustion analysis - more that satisfactory.
It took a while for the yellow tip on the flame to diminish, I believe its the dirt and dust burning after this boiler was not used for a long time.
When I classified a boiler at risk I give clear details of why - in this case the British Gas Engineer should have written it : Gas valve letting by 6mbar in 2 min., not telling the owner that the boiler need to be replaced and walk away,. That's what they have done. They have classified boiler at risk and gave a list of parts to be replaced and told the owner that they need a new boiler.
BG should have ID the boiler and written about the gas leak - but instead they AR it and told the owner that they need to replace it at extra cost. ( this is probably why Advertising board banned their advert - Look After your world advert it should be re-advertised as Look After BG Profits)
The boiler was repaired, and I am writing this after 3 months. Last week the owner called me telling that the heating in not coming on. when I checked it - the Honeywell room thermostat has gone out of calibration. It never make the switch live until the dial is at 30C regardless of the room temperature.
