Standing Pilot gas furnace operation and dismantling 

What Netflix and Movie streaming? This is all the you should need to be watching! Loving these videos. I watch them twice usually just to make sure!

THANK YOU VERY MUCH.ITS SOO NICE EXPLANATION ANG GREAT KNOWLEDGE. HELPED ALOT ABOUT FURNACE. PLEASE KEEP POSTING VIDEOS.

I always liked these standing pilot furnaces. They always start quietly with the big whoosh and the hissing sound from the burners. The power vent on the current furnaces are loud.

This is the most informational video on old furnace , I came across an unit like it today and it make me a little bit nerves, so I wish I could learn it before I went to the field. Thank you TY.

I knew all this but you explained it well so I gave it a thumbs up👍🏻

Great video,as always

Very useful and detailed. Really, I love it. Thank you

These are fantastic videos!!

Great voice, Well spoken, look for manufacturing spokes person work, videos on new equipment etc.

thank you very much! you inspire

These older furnace lasted and were relatively easy to work on but man after 50+ of other tech rigging things up, it could get irritating. apartment maintenance

Great video

By far the best video on RU-vid when it comes to these old style furnaces. Best video BY FAR!!!! One question. Maybe I have to watch the video again to see if you mentioned it but why does the collector box have an opening on the bottom? What purpose does that serve? Thank you

Well done, thank you for taking the time to post a great piece of information. I have an old P75 pioneer unit that's pretty similar, and your video was really helpful. TY

I had a furnace just like that in a House built in 1978 I dont remember if it was a rheem or ruud except it was a beigh color

Thank you for another amazing video. i have been watching your videos. will 3in1 oil work instead of turbine oil?

I have an old Johnson Air ease model HAS130 that quit yesterday ( it was 5⁰ ). I tested the thermocouple, went from 11mv down to 5 so as soon as the store opened this AM got a new one, installed , lit pilot and got it operating watched it awhile then I found your video - my furnace has the gas on for a min. or so then goes back to pilot with motor still running, then about a min. Later flames back up and repeats. I noticed you mentioned that in your vid so I checked the fan- limit switch and observed it doing as you said - twists around them back turning on / off the flames . I then removed the inlet filter and blew alot of fine dust out thinking perhaps the air flow is restricted not allowing enough airflow through the duct side of the exchanger causing an overheating problem making the limit switch operate . When I put the air filter back in I noticed the pilot had gone out -? It shouldn't have but I relit the pilot and tested - same situation with the limit switch. I just looking for some advice - now I am thinking perhaps the combustion exhaust vent might have a dead bird or something in it seeing the vent pipe goes up the old coal boiler chimney (1940 house). It does bother me that while I was blowing out the air filter , the pilot went out. ... Thanks for your videos, I hope you see this and can advise . Charles in Cheyenne Wyoming

Can you explain how a gas’s oven with a electrical heat element works (this element looks like the gas valve is in series with the element) Looks like the hot elament ignites the gas when the gas valve opens. Am I correct or is there more to this oven system. This is a caloric gas oven.

I guess the real question is why would you need to dilute the combustion gases? If that collection box was sealed then it would just vent out naturally wouldn't it? And you wouldn't have to worry about a backdraft pushing all that combustion air back and out of that wide open collection box. I'm confused of why even dilute the combustion gases to begin with

It’s the new systems that worries me more because they are so cheaply made the heat exchangers will leak within a few years the old ones were designed more solid I haven’t seen any old heat exchangers go bad except I see a ton of the new systems with bad heat exchangers that’s scary to me

I have question; I am HVAC tech and many times I faced pilot furnace and lots of Rust from heat exchanger and no heat . I tell client to replace furnace and even show the client that rust separated from heat exchanger not good but client starts to harrass me and says he wants heat . Personally I dont like to fix standing pilot because of safety but customers think that I want to sell furnaces to them but unfortunately I don't work for myself and work for company;otherwise i would not accept these kind of customers . If you make video how to deal with these customers;it will be great . Thanks a lot

If h.e. is 👍 keep it y replcace

Yeah. Old. Inefficient. Still works. The old man throws some oil on it, scrapes the flame sensor, brushes the burners. Still runs after 40 years. Blows hot air at the register. He kicks it up to 68° F or what Boomers call room temperature. Turns it down to 65° F at night. It kicks on once during the night if the temperature is above 30° F. Twice if it's below 30° F. My 90+% efficiency furnace? Can't oil it. Constantly service and replacing parts. Feels like a warm breeze at the register. Kicks on quite often at any temperature setting. Maybe twice an hour if set at 72° F or Gen X room temperature. Kicks on even more at 68° F to the point it might as well run constantly. Runs better at 72° F. Probably going to spend $7,000 next year to replace? It's been 15 years since installation. Which one is better again? Ohhhhhh... The one that keeps people employed.

Dismantling, not desmantaling. I’m not saying this to pick on you but rather to help people find your video more easily when they type in the proper spelling.
