Make-Up Air Start Up With A Problem

[@HVACRSurvival]

Sorry for the lower resolution, I forgot to switch my phone back to 1080. It's been corrected now.

[@retsbew8954]

Awesome job. I really enjoyed it, and I’m learning so much from you. You have become my favorite KZbin HVAC technician!

[@HVACRSurvival]

Wow, thanks for the vote of confidence 🤜🤛👍👍. I appreciate you watching it!

[@berylwhite2983]

Well I don't know who doesn't know about adjustable wrenches. I looked it up and they've been around since 1907. We've got some that date back to 1915 on the farm. Great job 👌

Gotta love the stuff you find downtown

[@RWRefrigeration]

Good video. Thank you for going over all the details. I have a MUA replacement coming. The holidays are setting everything for next year most likely. Happy holidays to you and thank you again for taking the time to make this very relevant and useful content for us.

[@HVACRSurvival]

Thank you!

Great job Rick! Interesting old building. That control is nice, I had one this past winter you could see all information from that control, static and temperature.

[@HVACRSurvival]

Sounds like the one I started earlier this winter, that one had vfds in the control box above the exhaust hood. Thanks for checking it out! Hope your doing well!

[@tbelding]

I will admit, when you looked at the gas pipe, and then immediately looked up, my thought process was. "Um.. It doesn't matter what that little valve above says. The main valve is in the _off_ position."

[@stephennichols4815]

I always set burner pressure with max airflow to ma. Pressure drop across burner and when VFD is minimum a flow pressure drop across burner is the minimum , normally but most of the ones I serviced was WeatherRite and they have burner profile dampers with. Damper motors and controller to maintain the proper pressure drop across the burner

Another great video. You are one of the best at understanding what you are working on....using manufacturing information to set up/ diagnose the equipment and understanding what you are doing....big brains on Mr Rick 😁😁😁😁. I always enjoy your videos and the way you explain things. Look forward to the next one and all the others that follow that.

[@HVACRSurvival]

Thanks thanks Jason, obviously I have to go through the manual myself and just re-familiarize myself with it. It's been 4 months since I've started one.

[@shifter8207]

Nicely done Rick! When I see one of those I’ll be ahead of the curve setting one up 👌

[@gregbowman3598]

Good one Rick 👍

[@scottlaferriere4499]

Hello Rick, Another great video, I had a couple of questions for clarification if possible. You had mentioned a couple of times the VFD running at 80 HZ I had not realized that the drive could produce that and also motor nameplate stated 60 HZ. You had also mentioned a couple of times that the Maxitrol maintains diff temp but I believe it only a discharge air temp controller, l do realize you were trying to set temp rise with the high fire adjustment Also a good idea to check flame signals which you may have done and not showed. Again great video.

[@HVACRSurvival]

I might have misspoken, the Maxitrol does maintain the discharge temperature, but you still have to do the max and min. case temperature rise. The manual tells you what size pilot you should have and what the minimum fire burner should look like along with the min. temp rise. They don't ask you to check the micro amps, there is all kinds of things we could spend time on but there more times than not its not needed. The motor was VFD rated and the speed it was at was from the factory, the factory claims to test these prior to leaving. I did not investigate why they had it that high, I didn't have time to research that, I only start a few of these up a year, I have not seen them set that high before but that's where they had it.

I've got the same old school Cooper Atkins thermometer , bulky and all but very reliable 👍...Great minds my friend , great minds !

[@HVACRSurvival]

That's actually a newer version I picked up cheap. I have two of the older ones. This one actually will switch to differential temp pretty fast and back to individual probe temps.

[@sterlingarcher46]

@@HVACRSurvival Right , I was wondering how come the displayed temp changed so fast , cause mine is rather slow . Great , now I want one ... 🤬

[@brianmillion-osborne6747]

Always look forward to your videos.! Thank you for making them.

[@HVACRSurvival]

Thanks Brian, I really appreciate your support by watching them leaving feedback!

[@Ted_E_Bear]

Thanks for sharing, Rick !

[@Eddy63]

A good old Sunday morning vid ... Thx , it was a good watch ...

[@HVACRSurvival]

👍👍🤜🤛

[@adamdnewman]

Looks like you had fun 😃

[@harrydickson4575]

Another great one ☝️ 👍👍👍

[@throttlebottle5906]

we don't need no stinking gas to setup the unit. 🙃 too funny they got ya! 🤣

[@jonnymac31]

Sweet, man.

[@mrfrenzy.]

Looks like the "RH" relay got knocked around in shipping, the release lever is loose and it's starting to fall out of it's socket.

[@tphvac87]

I don’t work on this type of equipment but I do find it interesting all those different controls and checks and balances that these things do is amazing! I’m a residential HVAC guy been in the trade for 16 years only done some light commercial work, RTUs mainly. 65-70 degrees outside it’s the end of summer where are you based out of?

[@HVACRSurvival]

In Ohio, that day was cooler because we got some rain but it's starting to swing cooler unfortunately.

[@scotts4125]

When it's ramping up it sounds like a crank no start.

[@johnwalker890]

Good job DJ Rick, I didn't know you worked on jet engine furnaces , to many controls and looks really complicated for me, I like it when things are basic or easy, To much like the democratic government where they want control and regulations, sorry if anyone is offered, I'm just tired of the chaos that democrats are making us go through, not trying to be political, not trying to take sides either.Good job again Rick. I'll stick to basics.

[@drodriguez394]

seems pretty cut throat at your company !

[@HVACRSurvival]

No they pay us really good but they expect you to do it right. Unless you want to be hourly and that pays a lot less than what I'm making.
