In the last 2 months, if at hand is a high twist, the pilot light surrounded by my Intertherm furnace goes out. The HVAC tech replaced the thermocouple but said in attendance seems to be a big downdraft. I have not have a problem like this contained by the 7 years I have lived surrounded by this house. Why now? The warmth here right now is -29C and windchill is -40C. I have to relight the pilot when I got up this morning, at lunch time, and when I get home from work. The service tech says at hand is nothing further he can do? Is within anything I can do to remedy this, even temporarily, so that I can weather through the storm we are having? Access to the pilot pale is through a 2 inch square spring-hinged trap door in the front of the element. I live in a manufactured home 40' x 40'. Recently a 12' x 4' laptop of metal siding blew off the hindmost of my home, which covered the center seam of my house and 2 attic vents are wide open open to the elements. Part of the problem beside the furnace maybe?
I assume your repairman checked the flue to generate sure the cap be still on. The other issue that is effecting masses is the radical weather that we are experiencing. The giant winds from masses different directions, the fluctuation in temperature as well. If you own excess snow accumulation on the roof and or around your furnace flue will affect draw or support draft. If wind direction is blowing against the roof frontage that the chimney is on or on the opposite side next more wind than usual could be rolling up and over or up below the flue cap. Another possibility would be skirting or foundation vent may need attention if the furnace get its fresh air supply from below the house.
It sounds as if you hold more drafts than heretofore so you should try to seal everything up as best you can.
I'd also breed sure the thermocouple isn't faulty; terribly often they are dodgy when brand-new so, if that wasn't the problem to start beside, it could have created one when it be replaced. I've found that replacing thermocouples as a prophylactic measure doesn't work since the alien ones fail more repeatedly than a working old one. I individual replace them when they actually fall short, now.
Answers: I have similar problem with 2 gas space heaters vertebrae in the 70's. They be vented via 6" stovepipe right through the wall, so the entire vent pipe be less than 8". It have a baffle outside, but anytime it was breezy, my pilots would burn out on both of them.
One daytime I decided to remodel the room they be in, and added a door so the room could be closed of from the rest of the house [there be no doors to close between the front door and the back door]. During a trunk blizzard, I went to check on the heaters and the pilot standard lamp was going strong to my surprise. What happen was, by adding up a door, I slowed the natural draft of nouns that flowed through the house.
I have a outlook that if you buttoned up the home as far as drafts go, the pressure inside your home might drop, and it might do away with the pilot light blowing out.
