These Diesel/Kerosene Heaters are CRAZY East to Fix and Maintain

[@greggo502]

Watched your video ,fixed my heater , Thank You!! It's people like you that make You Tube Great!!

[@Approtechie]

For all who are having problems with the flame blowing out when you put the cover on, I worked on this for hours and finally discovered that the two sheet metal vanes that direct air into the burner are the culprits. They essentially cause too much air pressure to the flame when you close the cover. My answer is to bend the vanes the opposite direction so they don't concentrate air to the burner. Mine works consistently now with no issues, with the cover on or off. Also, the air pressure adjuster is approximately level with the housing surface, at least on mine. Cheers!

[@charleswalter2902]

In 50 yrs. I have only had to buy 2 of these heaters. The first one finally died but the second one has lasted 34 yrs & is still running on diesel. These things are bulletproof.

[@WRWhizard]

Anyone who services oil furnaces will find all of this familiar. I would say that other than a clogged filter, a worn out nozzle would be a top contender for cause of failure. They erode and you can only put so many hours on them before the spray pattern gets bad. If you have the nozzle in hand, don't clean don't nuthin, replace it! They cost less than $10. The first number is rate of flow in gallons per hour at 100 psi. The second number is angle of spray, if it says A or B, that means hollow or solid. If it 's not a Delavan then H and S are obvious. If in doubt, take it with you to a supply house. If the burner has electrodes instead of a plug, then the most likely gap setting is 1/8" away from the face of the nozzle, points 5/16 out from center line, and gap 1/8" to 5/32". Trust me, I did this for a living for a LONG time.

[@seeveiw]

Have you worked off of the becket nozzle selection card and used a smaller nozzle and increasing the pressure to get the cleanest possible burn ? I did this with aero water heaters on installs after confirming with a good combustion meter you rarely ever have to clean them

[@WRWhizard]

@@seeveiw I have not personally modded any burner in that manner but that is exactly what the current "clean burn" technology is all about. Most new burners ship with the pump pressure at 140 or there about.

[@WRWhizard]

@@cd2920 I have worked on waste oil burners. That sounds slightly similar, but thanks for the info.

Mine won't light. Igniter glows and I see fuel spraying but it won't light and it shuts down. I put a new flame eye on same thing. Winter coming I need heat.

My Heater is a couple years old still clean on the inside yet it sputters starts puffing smoke and dies eventually. I took it apart and could see nothing wrong.

You do a very good job here. I have had my1,115 BTU Reddy Heater over 40 years. Not once has it ever failed me. This year I went to fill it up with K1 kerosene and it wouldn't fire up. It came on and ran for about 10 seconds and shut off. The ignitor was working and I cleaned the sprayer as you instructed and blew out all the lines. Still no igniting. I took the cover off the control panel and found a very small crack in a rubber hose going to the sprayer. I replaced it with some clear plastic surgical tube. It fired right up. I'm not sure how the rubbery plastic surgical tube will hold up, but at least I found the problem and will go to the auto shop and get some rubber hose...

[@kennycopeland282]

There is usually a fuel filter in the tank. I don't recall you covered that part. Also the ignitor (sparkplug) is sometimes a element that turns red hot. They go bad but are replaceable.

I fought one of these one winter. After everything a mechanic can try, the guy at the heating fuel place taught me the method. Nice man.

[@scottpolesel4957]

Awesome video very detailed. Went out and found my nozzle was plugged up cleaned and blew out running great now.

[@PainterD54]

There are several makes and most of the popular ones (around here anyway) are all made by Desa and use alot of the same parts. I noticed alot of them have changed from using the spark plug ignition to the two prong ceramic one, which probably stays cleaner longer. I run mine on diesel, which puts out more BTUs than kerosene (and doesn't stink like kerosene) so I'm happy and it works great!

[@robertstack3678]

Finally someone explained it so I can understand what might be wrong with mine. I'll get back with you thank you

[@Approtechie]

Two other problems I had with mine: the thermostat contacts were dirty/corroded and not letting current to the circuit board. I sanded them with a tiny doubled-over piece of sandpaper inserted between the contacts. I also discovered the circuit board wasn't working and the igniter wasn't getting power. The large 2.7k ohm wirewound resistor was burned out. I desoldered and removed it, found an old 3k ohm 25w resistor from a scavenged board and soldered it in - it works great! The igniter wire was also broken at the connector, I had to crimp a new connector on the wire.

I’m a service tech for jacuzzi and I work on like 100 different models of hot tubs, swim spas and automatic covers. I have only ran into one thing that takes a 10mm at work. I used it to adjust one type of cover 2 times. That’s the only time I ran into something needing a 10mm wrench or socket in 20 years. And a socket didn’t fit. When I use it is on car batteries and I think that’s where everybody lost them. Usually you take your tools outside or with you somewhere to a vehicle for that. Instead of working in the normal place people are used to. I think that’s why people lost that specific socket. My most lost tool is a flat blade screwdriver. I have lots of sets missing just the 3 flat blade screwdrivers I carry all the time. I don’t know what it is that makes me lose them but I have probably lost 50 of them over the years. Never lose Phillips they grind down to nothing or break first

Great video. I have a Master 150K BTU that is old enough to where I can't buy a replacement fuel tank since they are no longer made. It is leaking diesel out of the plug on the bottom. BTW, how do you remove that plug? Just use the biggest flathead screwdriver you can find? I know it has never been serviced in it's probably 20 year life so I will have to buy a lot of replacement parts but I want to get the fuel tank fixed before I go any further. The fuel neck is badly damaged and oblong. Someone drove a screwdriver through it looks like in an attempt to vent and make it run better so it leaks when you try and transport it with fuel sloshing around. I was told it runs for a while then shuts down. I think the first thing I'm going to do is take everything apart and try and get the fuel out of it and see if I can get that fuel neck straightened out. If I can't get it to stop leaking I might just have to punt. What do you think? Have you ever tried patching up holes in fuel tanks on these things? If so what did you use? JB Weld? Take it to a welder and pay them more than it costs to just buy a new one? Many thanks and again great video.

My guessing would be unburnt fuel. Check air pressure and lines, clean the nozzle, check that your spark plug is strong and the fuel is hitting it. Also some guys were saying they have too much airflow directed into the combustion chamber with the top cover on.

[@tralfazy]

@@dguiley I think that's a symptom of something else being wrong like the air pump pressure or a bad fuel spray pattern.

Hey thx,I have a Dayton,yellow one over 100 thousand with a thermostat almost new had now over five years,it worked first year and quit. Now I have more info……

[@MrJohnnaz]

99% of the problems with these things is low air pressure, because of a worn out pump. Once they wear out you are screwed. I just hooked up an air regulator and plugged into the shop air supply. Works great, no more messing around with air pumps, and you can adjust how much heat you want by just turning the regulator up or down. We had one of these units that had so many hours on it that there was nothing left of the inside housing it had literally burned up. The really old heaters had air pumps that were built much better than the newer ones.

I can get mine to run on about a 50/50 mix. Diesel is definitely cheaper but the heat output is lower (tip doesn’t glow as orange) and more odor. It also won’t ignite with too much diesel.

Yeah I was wondering the same thing. Mine is made for kerosene but I can mix about 50% diesel and it will run, just not as hot and it has more odor. Any more diesel and it won’t light so there’s got to be some difference for running diesel.
