Oil Furnace Clean and Tune! How to Prepare Your Unit for Winter. 

Not all service ppl are so thorough, this kid is a rock star. I work for a small family owned business and we do the same thing. When we do a service, its a complete service.

Next time you have them come out, ask them if they are changing the filters (there is also one in the pump), and watch them. If you pay for a cleaning/service and they are not doing this, don't call them again.

If protection is available, why not use it?

Yes, Ben is my older Brother! He has taught me a lot!

@ReubenSahlstrom he's taught me a lot too- and I don't even know him! Thanks.

isn't that what the filter is for? You'd have to flush out a lot of oil to clear out any significant amount of debris.

But you are also looking at flowrate @@roshi98

​@roshi98 no, it's a common thing techs do, it can clog before the filter, and those filter don't filter everything. . Dude didn't change the strainer and also those ignitor are close to 20k v not 10k. Who uses an adjustable wrench and not a 5/8th.

@@oilandfireguy1739 Glad someone else has #2 oil in their blood 😉

Not many for sale on Amazon but I did find this one. amzn.to/3RhTnu4

Just use two box wrenches. Special wrench not required

Strainer? Is there a strainer?

@@ReubenSahlstrom yes. Fuel pump on left side. A pump strainer. $7.00 There are 4 Allen screws on the cover Make sure valve from oil tank is off Good luck👍

If only that were affordable. 😉 Just kidding, that'd probably be a good plan.

I guess that's something you could do, but it is usually not necessary and you don't want to damage the insulation piece that holds the fire. Its really not that strong.

The firebox is not cleaned. Put the metal heat exchanger can be cleaned with what looks like a baby pottle brush but is made of wire and is has about a 30 inch long handle. It removes the soot thereby keeping the heat exchanger clean and efficient@@ReubenSahlstrom

@@monoralph1375 what model of furnace are you referring to?

The brush I purchased decades ago has light metal bristles with a long stiff wire handle. I have used at two different personal residences with oil fired forced air furnaces. The first had clean out ports to insert the brush. I also brushed from the flue pipe connection. Current furnace is a Williamson. Only place to clean the heat exchanger ti to remove the connection to the flue pipe. I work the brush around the drum and up/down the length of the drum while vacuuming with a stiff tube inserted in the heat exchanger. It gets brushed every year. I collect less than a cup of the black scale from the cleaning. @@ReubenSahlstrom

@@monoralph1375 Interesting! I have done this to lots of gas and oil boilers as they seem to soot up worse (likely due to cooler heat exchanger temperatures?) but have never been trained on doing this to modern oil furnaces. Perhaps it is something to consider.

Reason being? I haven't heard of that being an issue.

@@ReubenSahlstrom “Make sure that the sample point is before any draft diverter/hood or barometric damper so that the flue gasses are not diluted and the stack temperature has not been decreased by surrounding air used to balance the draft. “ - This reason specifically.

Yes that would make sense, which is why I put the probe in on the appliance side of the flue pipe, not downstream of the damper. The tester I was using has a long probe to test with, and I was able to insert it into the full undiluted exhaust.

For your sake don't take God's name in vain. Also, ideally you don't have to use a wrench, but it was a bit too tight for me to loosen.

God made the man that made thumb nuts and you used pliers to tighten it back on. All good just keep learning
