Trianco Boiler Cutting Out Constantly
Hi
I have a trianco eurotrader boiler, in a external boiler house. I had the oil pump, motor and photocell replaced approx one month ago after the boiler wouldn't work. Since then the boiler has continued to trip every once and a while. Now it it tripping after a couple of minutes. I have had a look at the forum and have taken the plug out of the water pump to see if it is turning - it is turning but I can't see if it is pumping alot of water. Should alot of water come out of this hole when the pump is running and the plug is out? If I press the button on the trip the boiler fires up and works for a short period then trip again. Any help is appreciated as I have already spent £190 on the above items and am weary of the person who fixed the boiler. I don't know whether to believe him or not. cheers |

Is the oil supply restricted by a blocked oil filter or a mostly closed valve? Is the fuel contaminated with water? If its tripping the lockout on the burner it will not be the heated water system which is causing it. Which make of burner is fitted to the boiler since Trianco use several types such as Riello, Inter-oil, RDB, Monoflame etc etc. Certainly if you have already had a new motor, oil pump, and photocell there is a limited number of possible other alternatives provided the parts fitted were new. Can you describe exactly what happens step by step from starting to lockout along with the timing. As a guide the burner motor should start to rotate, run for a few seconds driving the fan to purge the combustion chamber clear with fresh air, The ignition spark will commence and then the oil solenoid valve will open usually with an audible click. At this point you should hear the flame ignite. The light of the flame will illuminate the photocell which informs the sequence control box it is healthy. The ignition spark stops and the burner continues to run until the thermostat is satisfied or the power is removed. If no flame light is seen within about 10 seconds the burner stops and the sequence control goes to lockout. This varies but it will not reset straight away on most sequence controllers, requiring a few minutes to allow an internal timer to reset |

It trips a transparent box which lights amber, I just press the button in the middle of this box and the light goes out, the boiler starts and runs until it trips again. trips sooner when its hot I was reading this forum and around the net and thought that the central heating pump wasn't pumping the hot water away from the boiler quick enough thus causing it to trip. I left the boiler on a very low temp setting all day and it has been running fine for approx 14hrs. Is there any way to check the pump, to make sure its pumping at the right speed. its a Grundfos UPS15-50. Any suggestion is appreciated. cheers |

It trips a transparent box which lights amber, I just press the button in the middle of this box and the light goes out, the boiler starts and runs until it trips again. trips sooner when its hot Thr transparent box will probably say Sartronic 830 or something similar on it and this is the sequence control which operates the burner and monitors the flame when a heat demand is present. You still haven't told me what make the burner is but using a Sartronic suggests you may have an Inter-Oil burner unit with a Danfoss oil pump (the black block thing with the oil pipe going in). If you do then depending on the age it will probably have a solenoid coil mounted on a shaft. One fairly common failure mode found of late is for these coils to go open circuit when hot but remake when cooled by an indeterminate amount taking anything from a couple of minutes to several hours for the problem to occur. Its sheer indeterminate period often makes it very difficult to pin down. Other makes of fuel pump are also used so all I can reiterate is please give full details of your burner and oil pump etc. BTW have you checked the oil filter yet and was there any coating of sediment/muck on the element?

Is there any way to check the pump, to make sure its pumping at the right speed. its a Grundfos UPS15-50. Any suggestion is appreciated. Not all boilers have an overheat trip and in general all the overheat trip will do is remove all power from the boiler panel thus "usually" the power on light and others are simply dead along with the boiler until the overheat stat is manually reset. The lockout button has no connection with the thermostat system. This does suggest howver that the burner will fire for shorter run periods and whatever is causing the lockouts is not getting the same energised periods and avoiding the thermal effects. |
Hi
The sequential control is indeed a Sartronic 830, I dont know where the burner is, The oil pump is Danfoss Type BFP 11LS, the motor is bentone with a box above it which is Danfoss Type EBI. Where is the oil filter and how do I check it? also how do I check for contanination in the oil? Where is the solenoid? sorry about all the questions but I am new to this. cheers for your help |

Hi The sequential control is indeed a Sartronic 830, I dont know where the burner is, The oil pump is Danfoss Type BFP 11LS, the motor is bentone with a box above it which is Danfoss Type EBI. The EB1 electronic ignition generator could be a prime suspect especially with thermal effects being suspected. Since you said in an earlier post the oil pump was new this should be out of the loop for tracking this fault. Presumably the motor capacitor is integral with the motor but if not this is another possible option especially if you can watch the unit for some time and maybe catch it being sluggish to start the motor spinning. Where is the oil filter and how do I check it? also how do I check for contanination in the oil? Where is the solenoid? The solenoid is the bit with the flex connected to it on the oil pump discharge. The oil filter is usually on the outlet from the oil tank but sometimes inside the house or boiler casing. To carry out a basic check on the fuel system try shutting the oil supply valve, disconnect the oil pipe from the pump, put the end into a clear (clean) bottle at least 2 litres, turn on the oil and run about 1.5 litres of oil in to check that it flows freely and fast enough to satisfy a usage rate of about 5 or 6 litres per hour for every 1000 BTU of boiler rating. Turn off and restore the connections. Allow the sample in the bottle to stand and look to see if you can see any water lying in the bottom of the bottle (under the fuel) or any debris of any kind. Then dip a small piece of rag into the liquied, take it outside and light it in a safe place. If it burns easily you should be ok on that front. sorry about all the questions but I am new to this. cheers for your help -- technics100 |
I had the boiler guy out today to have a look at it. He said that the oil had water in it, but couldn't see where it was getting in. The oil line runs underground for a few meters, so it may have a hole in it and be taking in water. He replaced the jet and said it was soaked with water. Boiler is running now, but I just have to find out where the water is getting in.

Seems more likely than water pushing its way into a pipe. -- Rod www.annalaurie.co.uk |

Boiler is running now, but I just have to find out where the water is getting in. Very unlikely to be entering against the pressure of oil within the pipe! The usual place for water to get in to oil is via the top of the tank which someone has stood upon causing the "dishing" to collect rainwater which eventually rust through. Other places possible are sight gauges which have lost their rain cap and are located under a leaking gutter, tank lids which fit poorly and are under a leaking gutter also. Is your tank located where someone you could have upset might find it entertaining to put a hose into it? Its a very remote possibility that you might have had a contaminated load delivered but I'd put this a long way behind any other sources. If your tank is set up correctly it should slope away from the outlet and have a drain at the low end. If you have one, run some off from here into a bucket and check visually and by dipping a bit of cloth for a burnability test for water ( I went to a tank last year which had been vandalised and found clear liquid for a depth of about 200mm but it wouldn't burn, after a lot of draining off this underlying water eventually fuel arrived). Its often possible to get rid of any water collected in the tank via this method, in fact in days of old it was normal to do this as part of a six monthly service, usually blaming water found on condensation rather than the real source of refinery contamination. Modern production and storage methods have all but stopped water being delivered in the fuel. |

Please Help A new jet was put into the boiler on Friday and it was working fine until monday when it tripped. I then syphoned oil from the bottom of thetank to see if there was water in it. There wasn't. Since then it has started to trip more and more often. now it only runs for 15-30 mins and then trips. The boiler guy said its definitly getting water mixed with it. There is no water at the bottom of the tank. what do I do next? The tank is plastic... cheers |

Thanks for the clarification. I was trying to leave some useful information for Dave Baker with his boiler failure but my mobile access obviously doesn't suit everyones method of reading. I'll leave it at that.

You've been told once it's netiquette to quote some relevant information and you still go against Usenet convention. Your reply is possibly over 11 years late, don't you think the problem would have been solved by now, one way or another? I think you may be missing the point - he was highlighting that information in that old thread would be relevant to a recent one - not attempting to post new information to it. The delivery of the message may have been flawed, but in this occasion it does not warrant the shooting of the messenger! -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |
