hi Alu .............when was the last time they vacuumed out the chimney base?.........if it is old there could be a lot of debris collected down there..........can you smell almost a sweet hydronic smell? like a steam...........do you know where your damper switch is?..........next time it goes off....... try that and see if it comes back on........if your chimney is over 30 years old it would be a good idea to put a liner in
it should be a little button where the exhaust coming up from the burner to a round hood part and then to the flue..........but it should be on that hood part ..........look for anything with 2 small low voltage wires going to it .............being it is only 6 years old it might be an automatic switch............how old is the chimney ?
well that was the only thing I was going to suggest if it was in fact the flue and damper control............a seasoned veteran can put his hand by the hood and see if he is getting back pressure .....especially on a day when the air is heavy
I can opt out and see if one of my colleagues would be able to add anything else to this issue ..................good luck in resolving
of course .............don't click any rate buttons and you won't be charged for our time here..........once I opt out someone might offer a different perspective like I said to resolve your problem ............again good luck
Hello, tell me how the exhaust vent pipe is laid out from the furnace to the chimney, and all about the chimney, what size is it inside approximately, how tall is it, and what is it made of.
Tell me if this pilot going off situation developed over time or has it always tended to do that.
What size is gas line, and about how long is it.
Please describe the pilot flame, is robust and 'fierce' or a lot softer.
Describe what you see, while looking at the pilot as the main burner comes comes on, is the pilot flame being drawn off of the pilot?
So far I suspect the pilot orifice might be slightly restricted...
Thanks for the excellent feed back.
This should be the manual, let me know if this is what you have or not, and if yours has the display panel shown on page 24 and if it does, are there any error code read outs.
Regarding the issue of the flame not going out when the door is open, that would be because when the door is open, combustion air goes from the open front to the burners, and does not sweep up past the pilot through a bottom opening as it does when the door is closed. Look for that, and tell me how much space there is between the bottom of the boiler and the floor.
We can go from there.
Hello again, If you rate my input so far positively, you can get back to me next week even if the question 'times out' or says 'closed'..just post your remark anyway, I will get it, and we can go from there.
There is considerable risk running with the inner door removed, meantime look under the boiler for any debris that may be blocking the air flow, and causing the velocity past the pilot to increase.
