 Alright so we're heading to a no-heat call. Something about the pilot won't stay lit or something so we're gonna go see what's going on there and take a look. Alright you guys are in for a treat especially you young guys may not have seen this before so what we have is a gravity furnace and the pilot's out so ask them like I always do what's your left or your gas bill usually run a month and I'm always amazed when they tell me sixty dollars seventy dollars so which I find amazing because the gravity furnace no blower on it sat in there running those kind of bills it's like how do you even justify replacing a thing so I mean 20 bucks maybe savings a month I suppose it could add up over time if it even that because these are older folks so they probably keep it pretty warm it's a pretty good size house it's a single story I gotta get permission before I can show you anything but we'll go down here light it we're gonna see how the pilot looks the pilot a lot of times gets dirty and it gets weak and my procedure generally is to replace the thermal couple every time and then clean the pilot I grab my little blowgun here usually using my nitrogen but this one I got a little bit left in the tube yet so we'll clean the pilot out by blowing it out because unless you take it apart better off you're going to be less chance of breaking things so let's go in here and see if I can show you some some footage of it I figured people might enjoy kind of seeing this because they don't see these sort of things that often so yeah well some lady who works out there and hey she's got one too really it's always interesting so yeah that one's closed they just got natural venting there yeah yeah it's well you you know on some of them the gas valve was power piled so basically they self-generated their own voltage and they didn't even have to have electricity so yep on the old ones the really old ones so yeah they got a regular gas valve on there but no they they got rid of that that's kind of a illegal anymore yeah they kind of done got rid of that a long time ago because of the possibilities of malfunctioning so return air furnace with air conditioner you know we can hook you up with that not a problem yeah you know between the houses yeah they don't take up much room there yeah so it's right now we're getting along with a one you put in the window yeah and it's getting to the point where I think somebody's getting a little tired it's nice to not have to mess with it that's for certain and like I say if we was going to do it we might as well just do the whole thing does it go out very often no it's never gone out since you put that on there really okay yeah because it's staying lit but I like I said my usual procedure is to replace it I'm going to blow out the pilot there and get it cleaned up and then I'm going to replace that thermal couple okay that's what I think would be your best bet that way you have less chance of it going back out again it don't look too dirty at all it's actually pretty clean looking but just as precautionary that's what I'm going to do with it I don't like where that's at so I'm going to drill that a little bit out so that I can get that center piece up there a little higher so that it can be a little more I'd like about maybe eighth of an higher than what it is so I'll just drill that out just a little bit slowly I was able to put the vice grips there to hold it so don't rip my hand off and was able to get just enough that it lets that top piece through so it should fit now there we go I like that a little bit better we'll see how that is once we got a flame on it I just want to hit that probably half inch area we can look at the instructions but generally I like to hit a good portion at the top a little bit more and that screws in there nice and good so we're going to go ahead and get that back in there there's an orifice in there which I blew through that and I got that all cleaned out we blew out that main burner there ended up blowing any of the dust and stuff that's around the burner at the base there so any of the air combustion any of the air shutter area which would be traditionally an air shutter that way you can get the air through that it properly needs and they said this thing booms a little bit when it kicks on which is not a real surprise especially if this isn't a slow opening gas valve this comes on at a mad dash rush that's probably why it booms we'll take a look at we'll see what we got you didn't want to hear anything about that get those out of there now let's see how she kicks on the pilot is a little bit below the burners which generally is a good place for it and if the flame hits it so we'll kick it on kicked on pretty smooth now watch and see how it acts when we do the pilot off see how it kind of pulls on it kind of can see that close that do it again it's kind of be great to see a little better now we pulse a little bit on that but not bad and it's a slow opening valve which is a good thing so i like the way it comes on it's really nice and smooth and then once this thing gets hot it'll start venting a little bit better make sure that the chimney is clear too i don't help your chimney a lot you got a empty spot up here that should be closed off so i'm gonna have to make something up to kind of seal that a big old your chimney it's got a big old hole there at the top see that that that that reduces your draft that shouldn't be like that so i'm going on the side there yep right here probably from an old water heater or something i don't know so i'm gonna seal that up with some sheet metal it's about all i got on the truck i'm gonna inspect it make sure i can see daylight at the top there too make sure it's all clear and open yep you can see daylight plenty good so that's important to know that you aren't going to get the old sleepy sleep from carbon monoxide poisoning all right it's not beautiful but it's sealed so it'll work it'll you figure it's been working for how many years that way so it'll uh it'll at least uh help keep any birds from getting in there and stuff like that yeah they they would come down that chimney no problem rule fine little bird rule skinny they look like larks with great big tails yeah well i don't know if there's any particular bird it would try to sneak down one hole over the other but couple different ears didn't we same time we sprayed for gas leaks no leaks on any of the old pipes which always is kind of surprising for as old as that is you guys got all kinds of funny things going on down here yep it uh it's still on so it must have satisfied so i hope it is yep well on one way to find out now let's let it run so there we go got that dear back on i'm gonna say you're probably good to go we'll try it out see how it does if it acts up from there we'll just have to make some more adjustments on the pilot but i don't see that as being a reason so we should be good well you can see the chimney way up there and uh that was clear open it's not a real big house so i mean it's there all the way to the back so you know anyhow that uh hopefully was entertaining for you guys it's never seen a gravity furnace before and uh it's always amazing that the gas bill is as little as what it is so they should be good to go the biggest thing there was probably cleaning the burners out so that they were clean and uh it won't it lights off smooth and uh plugging off that chimney definitely didn't hurt anything to get a little bit better draft on it if you notice it had a diverter built into the flue pipe so that's how that works then the front of the furnace also had that flat plate there uh you know i wanted to make sure i had enough combustion air coming into it and that was kind of homemade looking as you noticed so uh just another one for the logbooks if you guys enjoyed the video make sure you do what you need to do and until next time guys we'll hit you on the next one
