How to set the oil furnace barometric damper

This one covers the barometric damper on the oil furnace and how to set it for proper vent vacuum.

Thanks a million for this. The kid ("serviceman") who came out today for the annual check-up has no clue what that damper is for. I asked him about the air/fuel mixture and he said that's only important in a car where there is pressure in the combustion chamber. God help us, the idiots are taking over the world. Thanks again for sharing this! Everyone should watch this!

This man knows what he's talking about he has years of experience ..Most important he shows you what will happen from one setting to the other..Troubleshooting, , best on Youtube, , , TY...Gray

Your videos are very informative.Thanks for sharing. I do not miss any! Even though I do this everyday as an hvac service tech. I learned that the real school is out in the field. Congratulations.

All oil furnaces should have a draft diverter installed from the beginning. You’re one who really knows how to interpret the draft readings. I’ve cleaned out my share of oil furnaces, that were running a positive pressure over the fire.

Thank you for the plugged heat exchanger comment. That was huge for me. Gosh there is so much I thought I knew but I don't. Even after 30 years working in the hvac world.

I know nothing of the pressure, or enough to know I shouldn't mess with it as a layman. I just oiled the swivel and wired a rig to keep it from locking in its extreme open position and eliminate the noise. It's real windy right now here and it is reactive to the wind. I wanted to keep the noise down (the bang-banging) as it returns with its force to it's resting position too without at all hampering it's full pendulum motion. Success, nothing but silence from the confounded (albeit important) contraption! Thanks for the explanations and expertise - very cool and informative video. My maintenance guys tell me the whole system is working really well - which is terrific considering how old the system is. Just a lil oil here and there (especially in the forced hot air motor) works wonders.

Thank you for all of the videos that you post. I am getting ready to go to school to be an HVAC technician and i watch all of your videos to get a jump start on the learning process

[robblacie]

Thanks for showing everyone what not to do. Looks like you are on a positive scale

I have question on my furnace I only get o readings on manometer. same meter as yours even with damper sealed closed. What would cause this. I have a tall mason chimney and no smell in basement. also on windy days damper will open even with furnace off.

[curtischamberlain]

My oil burner has no vent/damper on the chimney. There is a 2.5 x 4.5 inch door just above the burner that lets me look into the slot in the combustion chamber. This door has a screw allowing it to be adjusted to hold open at varying amounts. Anyone know if this should be adjusted like the damper?

I'm missing that weight and I don't know what is called or where to get it

[jeffhubler]

My heater does not have a barometric Damper. It is crawl space installed but I am wondering if I should fire the people that have serviced it and have one installed.

[mechanicwarrior]

Does the same rules apply for adjusting barometric dampers on natural gas boilers as well? such as cast iron sectional and firetube boilers?

[Vsmechanical_llc]

Very good video. What's the idea behind the barometric dumper?

[davekenna]

Do I need a damp my oil stove has a stove pipe that's about 6ft long can't go longer

[ghostridergr]

Pressure in the combustion
chamber on burner manual they have that to on mbar in we haft to be on this levels like manuals or we can ritch it all the time?

[russellsnyder]

I have a question i installed a trailer furnace welding n my garage I'm wondering if I can put a damper on the pipe that goes outside because it doesn't seem to push hot hot air i think I'm losing my heat out my pipe

[bkoz]

I am trying to figure out what causes a rumble at startup, when the burner kicks on after delay the damper slams shut quickly once and then works as normal. Eff test: 0 smoke, 11.5% CO2, 5.5% O2, Overfire Draft -.01 to -.02" wc, Damper Breech draft -.06"wc. Runs fine but damper slams at startup and there is a slight rumble at startup, oiled fired thoughts? thanks

[chrisvalery]

Great video. Can you recommend an inexpensive draft gauge for oil furnace.. Amazon has digital ones for $35-$75 . Thanks much

If the pressure was negative, why didn't the meter show "-0.04?" It seems like at times it was showing negative and at times positive readings. Specifically at the 2:00 mark.
