 That's a little change of pace for you guys Yes, I do heating and boilers and stuff like that. It's just a little burger. I was here back 1028 to 16 and Say the least customer asked for me back But today he's calling here. It is actually two years and a month later. And he says the spark box isn't working which that's one of those Older styles. It's got the goofy little plug here. All right This thing I did since he said it wasn't sparking So I went to my control board here. What's a little sparking nighter? He wanted to Follow the back is through the rollout Which is a thermal fuse and I hate those because So Then it comes back your time delay delay on great. That's to give it a purge so Check my power if you look at it There's the power going to it And then looks through here. So I went to here before or you can test across Thermal fuse and sure enough We had 24 volts So thermal fuse tripped This has a intermittent start to mission pilot with a mercury switch This is some older technology here. It's with a mercury switch. It's hot and then it closes and switches position one probe on the close to the normally open probe It's really old school, but it's pretty reliable to work the kind of expensive As they started having problems they start to come out with these little resistors you can put across these These things have been out for a long time. I haven't seen them for you'll see them any more hardly but Yeah, today's one of the days when they requested me so I got to In residential today Check the fleet pipe out. It looks good. It's all double wall pipe. Nothing's rusted out It's aluminum pipe there Got a concierge trap there when you blow So our pressures are fairly up So we're gonna jump that out and see what it runs. It does. We need to find out why it's ripped Take this replace it and hope it don't happen again Keep my hand on the valve just in case it don't light off. This is propane So light off kind of rough sometimes Really should probably have a door on The way all the gas stays in there and lights off a little smoother Probably do is grab the nice and bottom will blow that pilot out blow these burners out You see some of the burners are Starting to just form There's a lot of moisture and propane so it Sees burners out. We put a thermal couple in there if we want thermistor checks you that temperature is but there's A mess of different things it could be it could have been maybe the draft motor stopped and didn't purge it all out After shuts off. It's just really hard to say We're gonna let it run for a while and see if it'll show its ugly head. It could have been just a weak thermal fuse All right, what I ended up doing we bypassed it Thermometer in there That's a nice thing about these little needle probes It's right in there of the exact location And we sit down and watched it basically got up to 120 something I think This is rated for 228 grief So We're nowhere near the trip point another possibility if this plate wasn't tight I could let the heat come out the front And could have rolled out you can see we've gotten hot up here but That does not seem to be the case that cover could have been And you're a hundred and sixty So you get down to there in four hundred so they did Very easily could have gotten up to it Yeah, I forget how to switch it to Celsius, but we're looking good from what I can see I called I Called the supply house and at first they didn't think they had one but they do So I've got to go pick it up and we'll get it installed. We're going to clean as burners out and We'll have that pilot with nitrogen And should be good to go All right, we got our new thermal fuse in there Brought the original fuse rating there so that somebody doesn't go and remove it and change it something else blew out the burners and pilot Just a generic little attachment on my nitrogen bottle there The reason why it looks so bad is I got my light on so you're seeing all the little buzzies in the air We're gonna go ahead and kick her back on see how she runs Kicked on nice and smooth A lot of dust in there. It's got all the oranges from We got that fan to draft motor It sounds a lot better than it did. I think that dust was throwing some blades out of balance Just to point out a few things I did long as here last time A new take-off pump on that Got a new pop-off When I go working on a boiler and there's some things that need to be done some of the main things I always replace Is my bleed valves? Really check out the expansion tank really good pop-off safety If they have problems with bleeding it basically the way this works here You've got a fast blue a fast filter here on this There is your incoming water so you can isolate that I put one there. I do not put Union in there unless I Actually cut it out. So right now. It's one less thing to leak if I'm going to work on it Obviously, I got plenty of room in here to cut it and I put a Union in then Then What I'll do if I was to bleed just say from a complete empty state or whatever it did a major repair. I would fill it here Valvedor here Force it through the boiler Valved off down there and power bleed it basically out of it so you can flush fresh water through there If you had glycol in it, which very few of them around here do You could actually do what I did on the Geo's and hook up to wash machine hoses and a pump Run it down into a bucket and you could circulate the stuff You could do either one of those two things to get the air out of it now green it This is going to be in a series circuit to be able to make this work You could do it in parallel to you just like we do the Geo thermals Just gonna take longer and you're gonna have to have some major velocity But we're gonna blow out that trap yet I don't see trap which is down there Reason why I glue The pilot out and I'll do the same thing with mobile home versus and stuff a lot of times when you take them apart There's a good chance. You're gonna break the pilot strip it out or whatever the case and From my millions of times. I've done the pms and stuff. I've experimented with all kinds of different cleaners And then compared it to cleaning it and the nitrogen blows the chunks out of it and gets it Just as clean as taking it off and scrubbing it with a stainless steel brush and putting it back together Without all the potential damage. I did the same thing on a little water heater and stuff like that All right, just shut off and right there you can see that we're shutting off right around 180 We're setting at 185 for our set point and right at 20 pounds pressure That wraps this one up here Just thought I would show you something simple for today. I'll use this one for when I Got nothing much coming in Maybe it'll be of use to someone out there. It's starting out But otherwise, yes, we work on some small stuff just as well as we do some of the bigger stuff.
