Should this hole be sealed?
1 Attachment(s)
So I'm having my oil company come over to look at my "Brand New" oil furnace. I noticed that there is black smoke coming out the chimney when the burner is running. I'm not to confident with the old man who installed it because a few weeks ago it stopped working. We called and his wife answered and said he was in the hospital and was sending his son who is in HVAC school to come fix it...GEESH!

So it was just a faulty wire and has been working "perfect". Noticing the smoke from the chimney I went down and watched the furnace. There was a little bit of chunky soot below the flu coming out the top. That's when I saw this little hole. I also noticed a small amount of smoke wafting out of the hole into the basement. BAD I know. My question is should this hole even be there? Should it be sealed up with aluminum tape?

I'm hoping its just running rich and the tech can make some adjustments. I'm more concerned with the hole at this point. You can see a few flakes of soot in the pic. I had just wiped down the entire furnace an hour earlier before it fired again. So I know it just happened.

Very slight angle....The Fire Dept. Has to inspect and approve the system. They failed the previous OLD furnace because they stuck a camera inside and saw a cracked core.

Also is it normal/bad to leave the old damper? will is cause problems having 2 dampers? I hate contractors who don't have a clue!

Found out why the hole is there....For inserting probe and testing CO2,smoke etc. etc. sealed it up with aluminium tape for now.

It is now and has been burning quite dirty if you see that amount of soot. The bigger problem is that the heat exchanger is now sooted up and you are losing efficiency. It now needs a proper cleaning to remove the soot and have a qualified tech setup the burner properly with a combustion analyzer. Chimney should also be inspected for excess soot and may need cleaning.

Well my oil company tech was over and was like "who installed this?????"...As I guessed they did it wrong....spent about 20min settong it up and adjusting ratios....guess the original guy had it so it wasn't getting enough oil and too much oxygen...well its good now and running perfectly!

make sure you get it properly cleaned at the end of the season and checked with a combustion analyzer. even a very thin coating of soot on the heat exchanger works like insulation and slows down the thermal transfer thru the metal (losing efficiency) so that costs you lots of $$ and with the price of oil you don't really want that to happen.

looks like a Nordyne furnace, Your barometric damper is placed incorrectly and will not function as designed. When set up correctly that hole should not have anything coming out of it
