 All right, today's Fincher is a make-up bear unit that is not reducing heat We're going into winter time and the cooks are cold in the morning because it's been getting down to the 30s First thing I always kind of start with is belts and filters Because these work off of a pressure differential switch And if that differential is not there, it will not run You have a high and low fire adjustment with a variable amplifier for the gas valve And it will modulate to match the temperature rise of your choosing along with some high limits and flame rectification circuit there So that's pretty much the basis of how this thing works Big things is holy alignment holy wear Belt's being loose first thing it is went through and found what the required static to cross the burner plate is This one requires a point one five to point eight static between it. I Haven't tightened the belt yet because I don't want to correct the problem and not know that I corrected the problem I haven't checked temperature rise or any of that yet Builders aren't bad Let's check our differential first and see where we're at then we'll recheck it once we clean them First thing we got is a limo valve here probably opening. Yep That's opening right now Zero a meter out again They tend to have issues when they go from warm to cold operational circuits call in there We also have an airflow switch here on our Readout along with flame alarm and whatever else is going on. This must have a VFD on it They came up really slow Airflow wise were point two fours are differential at point one eight and point four two On our two different switches technically it should be closing According to this airflow switch is not but it may not be calling either Need to go downstairs and see where they got things at Here we go. Okay, so this is set to not run until it's at least 50 degrees out So we're gonna turn this up because it's gotten a little warmer today It is coming on right there at 60 58 60. So let's turn it a little higher. So it'll run heard gas five click We are so very close down here to where it's gonna trip out at We do have a flame established here Airflow is established operation controls there So so far we're not looking too bad our discharge air is set for about 55 degrees We can crank that up See if it changes anything Not hearing them the fan change speed. I'm gonna go downstairs and see What kind of control they got down there? All right, we've got our return air sensor hooked up Our supplier sensors in the blower compartment area is not a real great place for it to put it I can't get into the actual supply We could check flame rectification DC voltmeter See if it's actually picking anything up I mean it was saying that it had a flame so it probably is but Let's see where we're at on it. I've got 15.7 volts. They went between 12 and 18 So that's that's good. So we do have a flame It's at very minimal right now. So that part's established Now if we take our temperature rise here up to say 90 degrees See if it starts changing at all It's not Do we have a problem with our amplifier or valve? Kind of nice. It's got built-in gauges get Right around seven and a half inches coming in Doesn't look like anything going out and turn it back down. Let's go downstairs and see where they have it They may have a remote System on it just got ready to take off and all of a sudden she just shot up to wherever it was that there It might just be a slow learner. Let's see if we can hit 70 degrees 70 is not too much to ask for Like my fluke a little better Yeah, 49 going in Overshooting my 70 mark I was looking for There it is coming back down Down there basically it has a maximum air setting and it has a Savings setting so on the maximum air the speeds obviously increased a little bit We're at a point three four to point four differential The maximum it can go up to is point eight. So that's with the filters out of it Honestly, I believe this is going to boil down to just plain maintenance as being an issue clean filters tight belts Good pull is aligned filters are back in down to a point two plane is on shooting for a 55 degree area, which we're holding about 59 outdoor temperature It's 54 so it is actually running. Let's go ahead and take it back up to 65 see if it can do that. I did clean the flame sensor when I first got here Couldn't get a good description of what was actually the problem. Just felt a little cool, but That's what I was told You go over here and check their flame Right there which it's all UV bleached out and can't see it you cover your hand there You can see it. It's it's running. I'd like to see that airflow a little higher. I Think our issues boiling down to that. I think the switch wasn't shutting and allowing it to run if that was the case I'm also getting a lot of radiant heat. That's one thing bad about where I've got my probat So I would say it's probably accurate Okay Well, what I'm going to do Turn it down Let her cool down. I'm going to line that belt tighten it up a little bit and then recheck it You hear the belt going Making noises. That's why I think the alignment's off but It really ain't So, I mean there's a little bit Not much I mean on the top pulley we're pretty on The bottom just a scoche Tighten that up and see what happens the motor starts to bend you get too tight 16th of inch per foot That is About two foot so That'd be an eighth of an inch I think it's a little more than an eighth of an inch Actually have a belt tension tool would be a lot easier I think but We'll play by their rules That's a lot better Tighten up the lock nut here Just the other side of the pulley too or the other side of the Actually better shape there And we're in pretty decent shape there too Okay, we're gonna tighten up that other side because we don't want tilt I just like to wipe the grease sirk head off first And then you want to rotate They're bearing as you add To it. You don't want to over grease it You've sort of seen a lot come out and you've already over greased it so that and a couple pumps probably hasn't been done For a while I'm gonna fill your pole these See if the sheaves are a war which This outside right ones were like crazy And see what's gonna happen with that being wore like that you're gonna wear your new belt down So I'm gonna tell them they need a new pulley Here's a cool thing about captive air also They've got all the specs that I needed right out here your Maximum pressure drop across the burner is right there your temperature rise Everything you need is right there Rechecking our pressures here. We're at point three nine point four So not really a huge difference So what we ended up having to do was address our pilot flame It wasn't always acting up. So that kind of made it a little difficult to find and Ended up finding a room thermostat that it also monitors the room temperature not mounted where it should be at so we corrected that right now I just cranked it up to 90 degrees and She's shooting right up there basically it was locking out prior to but it didn't do it at first and that was due to a weak flame adjusted the pilot flame on the gas valve and Once that was done. I had a good flame no longer was it locking out and Appears now that everything's taken care of we're going to order a new pulley belts and Then get belts for the other exhaust hoods while we're at it and That should wrap this one up If you liked the video, please like share and subscribe Check the links out down below for more information and until next time.
