00:00:03.130 [Music] 00:00:05.82900:00:05.839 welcome to TC - my name is Bill Bailey 00:00:09.29000:00:09.300 and I'm a hydraulics manager here since 00:00:11.20900:00:11.219 about 2004 today what I wanted to show 00:00:14.29900:00:14.309 you is basically how to clean the temple 00:00:17.09000:00:17.100 HTP gene only heat exchanger over here 00:00:21.17000:00:21.180 this is the actual one piece for the 00:00:23.42000:00:23.430 heat exchanger we're actually going to 00:00:24.85900:00:24.869 clean in a high-efficiency boiler 00:00:27.56000:00:27.570 maintenance is critical 00:00:29.02900:00:29.039 you've got to keep this coil clean in 00:00:31.22000:00:31.230 order to you got good heat transfer so 00:00:34.16000:00:34.170 that's we're going to talk about today 00:00:35.22900:00:35.239 not really that cop Kahler hard to do 00:00:37.91000:00:37.920 there's a few pieces of equipment 00:00:39.59000:00:39.600 they're gonna need one is a pipe wrench 00:00:43.11900:00:43.129 we're going to need a set socket set the 00:00:47.51000:00:47.520 ten millimeter socket on it scotch brite 00:00:51.79900:00:51.809 pad for cleaning the spark igniter in 00:00:55.02900:00:55.039 the flame rectification probe a ball of 00:00:59.63000:00:59.640 a good coil cleaner and also bottle of 00:01:02.24000:01:02.250 water to rinse with the coil a cleaning 00:01:06.64900:01:06.659 brush or a layman's term a barbecue 00:01:09.95000:01:09.960 brush so all this don't make this 00:01:12.20000:01:12.210 complicated and an Allen wrench okay so 00:01:17.30000:01:17.310 let's get started first thing like any 00:01:20.51000:01:20.520 boiler application or other maintenance 00:01:22.73000:01:22.740 you're going to do we're going to turn 00:01:24.10900:01:24.119 off the power I want to make sure we 00:01:26.92900:01:26.939 have to get shut off okay now let's open 00:01:29.78000:01:29.790 up the boiler for demonstration purposes 00:01:50.42000:01:50.430 we did hide a light in here so it's not 00:01:52.01000:01:52.020 going to be this bright all right but 00:01:55.46000:01:55.470 you'll find first to the door the door 00:01:57.13900:01:57.149 has the control board itself all the 00:01:59.92000:01:59.930 safeties all the different wiring and 00:02:01.88000:02:01.890 everything comes right to here simple 00:02:04.06900:02:04.079 thumb screw here opens it up and gets it 00:02:07.60900:02:07.619 out of our way 00:02:11.11900:02:11.129 can't pull the cord the ribbon court but 00:02:13.45900:02:13.469 it's not necessary next thing you want 00:02:16.69900:02:16.709 to do is basically take your allen key 00:02:19.11900:02:19.129 go into here down unscrew and basically 00:02:23.20900:02:23.219 take off you can take two minutes what 00:02:27.22900:02:27.239 this does is basically funnel the intake 00:02:29.53900:02:29.549 air into here to get a good swirl 00:02:32.03000:02:32.040 pattern going before it gets into the 00:02:33.77000:02:33.780 blower nothing to clean their next thing 00:02:38.69000:02:38.700 you want to do is go ahead and pull some 00:02:41.44900:02:41.459 of your wires miss your spark cable 00:02:44.17900:02:44.189 right here this is your ground right 00:02:47.33000:02:47.340 here this is a wire to a flame 00:02:50.21000:02:50.220 rectification Pro goes throughout now 00:02:54.92000:02:54.930 you come down to the gas right here you 00:02:59.36000:02:59.370 loosen this up with our pipe wrench pre 00:03:01.69900:03:01.709 loosen a little bit just make it easier 00:03:03.46000:03:03.470 this demonstration get that out of the 00:03:06.40900:03:06.419 way now we take our socket the end take 00:03:13.19000:03:13.200 off the ten millimeter nuts as you can 00:03:17.59900:03:17.609 see already taken five off just to make 00:03:19.46000:03:19.470 this simpler so we get into the real 00:03:21.02000:03:21.030 meat of the matter in the heat exchanger 00:03:26.50000:03:26.510 there's our sixth nut go to seed wait 00:03:30.86000:03:30.870 ready to go also pull two wires to mulch 00:03:35.33000:03:35.340 stalks that hook up and attach the 00:03:37.03900:03:37.049 blower motor so now with the door open 00:03:39.74000:03:39.750 just grab this and basically what we've 00:03:43.58000:03:43.590 done is pull out the whole burner door 00:03:44.89900:03:44.909 assembly in one shot okay let's set this 00:03:48.58900:03:48.599 off to the side for right now inside me 00:03:53.56900:03:53.579 what you see it's the actual coils these 00:03:58.15900:03:58.169 are where the waters inside here our 00:04:00.80000:04:00.810 combustion is inside here in this one of 00:04:04.46000:04:04.470 us is 80,000 BTUs we base that three 00:04:07.64000:04:07.650 coils right in front it's not 00:04:09.40900:04:09.419 necessarily know that doesn't really 00:04:11.03000:04:11.040 matter button just for information sake 00:04:13.84900:04:13.859 that's what we got there in the back 00:04:18.26000:04:18.270 we have it's called the target wall 00:04:21.32000:04:21.330 basically if you look at the burner what 00:04:28.02000:04:28.030 happens is this burner sits all the way 00:04:30.93000:04:30.940 back up against this target wall here 00:04:32.61000:04:32.620 and this where flame comes out so let's 00:04:36.15000:04:36.160 clean the boiler first then we'll talk 00:04:37.74000:04:37.750 about a few other things here as we go 00:04:41.36000:04:41.370 what you want to do is look at the heat 00:04:45.48000:04:45.490 exchangers themselves look at the target 00:04:48.00000:04:48.010 well if you see any indication and tired 00:04:52.26000:04:52.270 a wall of discoloration I'm talking 00:04:55.83000:04:55.840 about drawn line or something like that 00:04:57.87000:04:57.880 in there start looking at the condensate 00:05:00.24000:05:00.250 drain that means something back enough 00:05:02.07000:05:02.080 all right so basically in this 00:05:04.50000:05:04.510 application there's nothing here we want 00:05:07.14000:05:07.150 to cover their target wall easy set 00:05:10.67000:05:10.680 device use it basically paper plate it 00:05:13.98000:05:13.990 sounds simple but it is simple you want 00:05:16.95000:05:16.960 to cover that target wall up they don't 00:05:19.05000:05:19.060 like moisture they don't like water 00:05:21.42000:05:21.430 being sprayed out so now we've got a 00:05:23.88000:05:23.890 paper plate back here covering that 00:05:26.79000:05:26.800 target wall we take a big coil cleaners 00:05:30.12000:05:30.130 doesn't matter what you like what you 00:05:32.10000:05:32.110 prefer or we're looking for something 00:05:34.29000:05:34.300 that's going to get rid of the buildup 00:05:36.66000:05:36.670 of the combustion 00:05:38.40000:05:38.410 well the chunk that's been getting 00:05:39.99000:05:40.000 sucked into this boiler get it off of 00:05:41.70000:05:41.710 there 00:05:42.15000:05:42.160 I'm going to take this I'm going to 00:05:44.16000:05:44.170 spray down all these coils getting nice 00:05:46.23000:05:46.240 and wet we don't have to type worried 00:05:48.18000:05:48.190 about the target wall because we've got 00:05:49.86000:05:49.870 the paper plate there protecting it let 00:05:52.83000:05:52.840 that soak a few minutes if you walk into 00:05:56.40000:05:56.410 a boiler that has a lot material and the 00:06:00.75000:06:00.760 bodies don't wet get your shot back suck 00:06:04.80000:06:04.810 it up make your life easier alright so 00:06:07.77000:06:07.780 now it's been 2 or 3 minutes we've let 00:06:09.45000:06:09.460 that coil cleaners soak in what we want 00:06:13.20000:06:13.210 to do is get our brush this like I said 00:06:16.50000:06:16.510 nothing more than a barbecue cleaning 00:06:18.72000:06:18.730 brush 00:06:20.08000:06:20.090 you want to make sure that the bristles 00:06:23.11000:06:23.120 our brass or stainless steel never use a 00:06:27.70000:06:27.710 steel brush and stainless steel you'll 00:06:30.49000:06:30.500 actually scour the metal that will allow 00:06:33.15900:06:33.169 that metal to basically start to 00:06:35.08000:06:35.090 deteriorate take your brass brush and 00:06:38.43900:06:38.449 basically anyone do work that way 00:06:41.05000:06:41.060 cleaner in to the heat exchanger to 00:06:44.43900:06:44.449 loosen up whatever thread is there they 00:06:48.28000:06:48.290 might take a couple times around but 00:06:50.05000:06:50.060 basically pushing around they're not 00:06:51.96900:06:51.979 going to come out perfectly break clean 00:06:54.12900:06:54.139 like brand new but you want to get that 00:06:56.05000:06:56.060 chunk out of there okay so look at all 00:06:59.08000:06:59.090 that does now we want to take our water 00:07:02.59000:07:02.600 bottle and just spray everything then so 00:07:07.18000:07:07.190 I'll let stop we loosened up we remove 00:07:09.79000:07:09.800 from the heat exchanger coil we want to 00:07:12.25000:07:12.260 wash it up I'm gonna take our bottle of 00:07:14.46900:07:14.479 water spray it down lavalla virgin yet 00:07:17.92000:07:17.930 we want to watch what's coming out the 00:07:19.87000:07:19.880 drain in our neutralizer we want to make 00:07:22.24000:07:22.250 sure as much water as we're spraying in 00:07:24.37000:07:24.380 is coming up if that we better go look 00:07:28.69000:07:28.700 at the drink there's something blocking 00:07:30.19000:07:30.200 it up I thought the whole bottle of 00:07:32.29000:07:32.300 water in here and I get a dribble out 00:07:34.65900:07:34.669 here I mean something's clogged up in my 00:07:37.93000:07:37.940 drink 00:07:38.37900:07:38.389 I better go investigate on this blue 00:07:41.14000:07:41.150 it's very easy there's a little sock on 00:07:42.82000:07:42.830 the bottom you can open it up and flush 00:07:44.58900:07:44.599 it out alright so so far we clean the 00:07:49.62900:07:49.639 coil or put coil cleaner in there we've 00:07:52.20000:07:52.210 taken the brush to it 00:07:53.98000:07:53.990 loosen it all up we've rinsed it down 00:07:56.52900:07:56.539 watched all that crud go down the drain 00:07:59.25000:07:59.260 okay 00:08:00.77900:08:00.789 at that point let's go back over here 00:08:03.85000:08:03.860 and look at the actual burner door the 00:08:06.61000:08:06.620 blower and the other accessories here 00:08:08.77000:08:08.780 before we put this back together this is 00:08:12.12900:08:12.139 the actual burner on this boiler okay 00:08:16.71000:08:16.720 alright 00:08:18.01000:08:18.020 combustion air comes in here our gas 00:08:21.04000:08:21.050 comes in here gets mixed here this is 00:08:25.33000:08:25.340 our blower motor that shoots it down the 00:08:28.08900:08:28.099 burner tube 00:08:29.37900:08:29.389 and into the burger and here I'll get 00:08:33.49000:08:33.500 this out again just like a target wall 00:08:36.49000:08:36.500 this is called the front refractory same 00:08:39.45900:08:39.469 material I want to look for any moisture 00:08:41.92000:08:41.930 line if there is that means I got a kind 00:08:44.17000:08:44.180 of C issue it's backing up there's not 00:08:46.75000:08:46.760 good to go I want a good look at my 00:08:50.41000:08:50.420 flame rectification probe and my spark 00:08:54.40000:08:54.410 igniter I want to clean up basically the 00:09:01.54000:09:01.550 easiest way to clean these is to take 00:09:03.85000:09:03.860 the two screws and pull them out and 00:09:06.10000:09:06.110 then clean them the biggest thing that 00:09:08.07900:09:08.089 you want to make sure is you wanna use 00:09:09.85000:09:09.860 so Scotch by pret but this is what you 00:09:12.88000:09:12.890 want to use you don't want to use 00:09:14.07900:09:14.089 sandpaper you don't want to use sand 00:09:17.07900:09:17.089 cloth you don't want to use steel wool 00:09:20.22000:09:20.230 any of those items normally leaves a bit 00:09:24.75900:09:24.769 of residue on this flame electrification 00:09:26.82900:09:26.839 problem once that starts excited getting 00:09:30.46000:09:30.470 heated up it has a tendency of covering 00:09:33.00900:09:33.019 this up again so now you just clean this 00:09:35.31900:09:35.329 whole thing everything is great two 00:09:36.46000:09:36.470 weeks later you've got a call that 00:09:38.41000:09:38.420 you're not getting good rectification 00:09:41.38000:09:41.390 you come back to the singlets all rusty 00:09:43.84000:09:43.850 that was the residue left from that sand 00:09:46.50900:09:46.519 cloth or that steel wool that you used 00:09:49.13900:09:49.149 so go I some of these they're cheap 00:09:52.48000:09:52.490 inexpensive they work great you won't 00:09:55.68900:09:55.699 have that issue okay so that's your 00:09:59.74000:09:59.750 flame rectification probe that's your 00:10:01.99000:10:02.000 spark igniter again like I said pull 00:10:05.19900:10:05.209 them out clean them up put them back in 00:10:08.31000:10:08.320 if you ever forget which one goes where 00:10:12.09000:10:12.100 always look for the site class site 00:10:15.75900:10:15.769 class spark igniter why would they be 00:10:19.03000:10:19.040 next to each other cuz we're all I do 00:10:21.57900:10:21.589 the psych class I want to see the spark 00:10:24.03000:10:24.040 so that means that spark igniter to be 00:10:27.79000:10:27.800 next to the site glass no mixing them up 00:10:31.11000:10:31.120 will they work the other way sure but 00:10:33.49000:10:33.500 you'll never see the spot 00:10:34.60000:10:34.610 so it makes sure spark igniter say class 00:10:37.87000:10:37.880 you're good 00:10:38.96000:10:38.970 go right so now everything's good here 00:10:42.53000:10:42.540 if you've got to do anything to the 00:10:44.36000:10:44.370 burner itself it's nothing more than 00:10:46.06900:10:46.079 brushing it off we don't want to take 00:10:47.60000:10:47.610 anything to this this brush file look at 00:10:50.56900:10:50.579 it inspect it alright so getting back to 00:10:55.28000:10:55.290 a boiler hopefully everything's dried 00:10:57.74000:10:57.750 out 00:10:58.24900:10:58.259 it's not your first combustion will be a 00:11:00.55900:11:00.569 little rough but that's not an issue 00:11:02.67900:11:02.689 remove the paper plate get rid of it 00:11:07.06900:11:07.079 it's garbage you want to come back in 00:11:09.82900:11:09.839 now take our whole burner door assembly 00:11:14.76900:11:14.779 take the wire connections on the bottoms 00:11:17.36000:11:17.370 the blower and the system now basically 00:11:28.73000:11:28.740 what I like to do first is just put a 00:11:30.82900:11:30.839 tough couple of the nets on don't get 00:11:34.28000:11:34.290 them all on don't tighten them all up 00:11:35.80900:11:35.819 put a couple oh man so that's going to 00:11:38.24000:11:38.250 hold this in place then go ahead and 00:11:42.53000:11:42.540 make a chance or so got a little bit of 00:11:45.41000:11:45.420 wiggle room adjustable if you have it 00:12:00.57900:12:00.589 going easier 00:12:02.32900:12:02.339 and tighten it all the way playing 00:12:08.38900:12:08.399 rectification chrome wire hook that up 00:12:16.17900:12:16.189 take your ground wire hook your spark 00:12:22.00900:12:22.019 initial table now you can go ahead put 00:12:29.24000:12:29.250 the rest of the nuts on when you tighten 00:12:34.57900:12:34.589 up the nuts just like a tire work the 00:12:37.42900:12:37.439 way around the circle 00:12:38.68900:12:38.699 sorry there's six of them but we're 00:12:41.66000:12:41.670 going to see you work around the coils 00:12:44.42000:12:44.430 so basically what I'm gonna do is hit 00:12:49.36900:12:49.379 six let me take it I have to sit one up 00:13:04.00900:13:04.019 so what you got to do so you get even 00:13:06.09000:13:06.100 poetic do not need to crank these I 00:13:09.78000:13:09.790 don't get ridiculous without it's really 00:13:12.99000:13:13.000 no pressure in that chamber so I get up 00:13:21.21000:13:21.220 to Facebook you wanna get that's it okay 00:13:24.42000:13:24.430 I go around and do the same to the other 00:13:31.59000:13:31.600 four alright so basically we hooked up 00:13:35.30900:13:35.319 our gas hooked up my hairs for blood 00:13:38.60000:13:38.610 we've hooked up all our other 00:13:40.47000:13:40.480 electronics at that point we're good to 00:13:43.29000:13:43.300 go so now we would turn the gas back on 00:13:46.67000:13:46.680 the electric that bad and fire the 00:13:49.53000:13:49.540 boiler the first time you fire it after 00:13:52.67900:13:52.689 cleaning it might sound a little rough 00:13:54.31900:13:54.329 that's because there might be a little 00:13:56.06900:13:56.079 bit of water still in there in those 00:13:58.23000:13:58.240 coils or whatever don't worry about that 00:14:00.86000:14:00.870 light it off the gang let it go through 00:14:03.90000:14:03.910 its cycle go ahead put your combustion 00:14:07.41000:14:07.420 analyzer on it make sure it's within 00:14:10.07900:14:10.089 specs and you're good to go any type of 00:14:13.86000:14:13.870 gene on a heat exchanger my 00:14:16.13900:14:16.149 recommendation can work with these 00:14:17.69900:14:17.709 boilers for the last 15 plus years do it 00:14:21.24000:14:21.250 the first year after install if it looks 00:14:25.11000:14:25.120 dirty you got very dirty you I'm doing a 00:14:26.79000:14:26.800 yearly basis it's pretty clean that poor 00:14:30.09000:14:30.100 the might need only be done every other 00:14:31.29000:14:31.300 year but don't forget to do maintenance 00:14:34.29000:14:34.300 and high-efficiency boilers if you don't 00:14:37.73000:14:37.740 we'll lose all that efficiency that the 00:14:41.85000:14:41.860 customer 00:14:42.46000:14:42.470 for basically any questions give us a 00:14:48.16000:14:48.82000:14:48.830 thank you 00:14:53.08000:14:53.090
