Question about Water Heaters

1 Answer

I have a miller furnace with a becket burner. it is in a moble home and burn keroseen. My problem is I ran out of fuel and went to get more got 20 gal and put in tank. I have done this before and it started back up with no problem. This time it wont fire up and trips safty switch until i can reset. I have tried to manually bleed the two line system and it just seems like it wont get solid pressure. the motor dont sound like it usually does when I close the bleeder (usually sounds like a lugging motor) now it sounds like it is just running will not fire up. I do not see a filter anywhere is there one internal? where can I find a detailed diagram of the whole essembly?

2 things to check one to make sure you are not picking air from tank dis-connect the inlet side only of the feed and rig you a hose or copper tubing inserted into a gallon can or bucket full of oil , try to run off this must bleed as before if it does pulling air from tank , if not and while bleeding you get the same on load sound from the motor then check this , between the motor and the pump there is what is called a boot coupling that transfers power from the motor to the pump most of these are rubber and with time and heat will sometime allow the drive in the ends to rotate internally cheap part usually $9 before replacing hold the old one against the new mark and cut the exact length as the old one , match the end you need with the same end that come off old one as these kits come various parts for different hookups , also a leak in the line will also cause same symptoms ck as much of the line as possible for damage , try these and get back with results and if no fix will try to assist further

I just had my furnace cleaned it is a gas rheem. The service guy said it was overheated because of a#3 tube he said the furnace heat exchange is black. What can be do regarding this


I presume you're talking about a gas furnace, even tho the title says Rheem gas water heater. Either way, it works the same for both.

Any black coloring on the heat exchanger is *not* from overheating. Black is from a sooty flame caused by a mis-adjusted burner. (In fact, a sooty flame is less hot). There is an adjustable "air intake plate" for air to enter the burner where the gas enters the burner. A proper flame is made by adjusting this air opening so the proper gas/air mixture feeds into the burner. If the air vent is closed too much it produces a sooty flame.
The age of the furnace is the most important aspect, and that helpful to determine a likely condition of the heat exchanger and burners. Other than a badly adjusted flame, the main thing to watch for is a badly rusted out heat exchanger. But black does not mean rust.

Oil furnace only produces cool water intermittedly and only when heat is actively on


For clarity, a Furnace produces HOT AIR for heat while a boiler produces HOT WATER for heat. Just remember...boil = water. You said your "furnace" does not produce hot water for a shower and because furnaces do not product hot water unless they have some model that do???? Usually people with a furnace have a seperate hot water heater. People with boilers though can produce hot water for use as both their sinks/showers hot water and their heat (by heating water that goes through baseboards) in their house. I don't believe any furnaces produce hot water most of the time a furnace just produces hot air for heating. So figure out what you first have.
Having said that, I'll assume you have a boiler like I do and my Weil McClean(sp?) stopped working a while back and wasn't turning on to "boil" any water. I took apart the burner and there is a light sensing photo resistor as part of the controls. If this phto resistor goes bad, the boiler will not start. The resister is cheap, I think it was $8 but you have to know what you're doing to change it. So you may be better to call someone who can work on such equipment.
Boiler's themselves are not overly complex. Home heating oil is the same diesel fuel that you can buy in a gas station only the government has "oil" companies put a RED die in home heating fuel which is usually cheaper then Diesel fuel because diesel fuel is taxed to death. The reason they do that is so that if you try putting RED tinted home heating fuel in your truck and you get pulled over (because you're a trucker with and 18 wheeler and they typically do inspections of these trucks) you will be a huge fine if they see you're running home heating fuel and NOT paying your taxed by purchasing Diesel fuel. A little bit of background so you know the fuel you are dealing with here. So it's dieslel fuel without the tax you run in your boiler. Gasoline on the other hand is VERY explosive as you know, but diesel fuel (if you're ever tried to light it) takes some coaxing to get lit. When it's cold out, diesel fuel is very hard to light and that's why trucks use glow plugs. You don't need those in your home though.
But because diesel fuel/home heating oil is hard to light, it's sprayed as a msit into your boiler, so that it can light more easily.
But because it is a fuel, you should know what you're doing when messing with it. FInd out what you have, and then have someone work on the issue if you haven't already. I'm guessing you have had it fixed by now?

Riello burner


You need to measure the manifold pressures before and after the gas valve and adjust accordingly to fuel used, 3.5" NG or 11" Propane.

The burner lights runs for 2 to 3 seconds then goes out


If you have an older heater I would replace the thermocouple. They tend to burn out, as mine did on my furnace. Relatively easy to replace if you have any home repair skills at all. They can be purchased at any hardware store and come in different lengths. If not have a trained heating expert do it for you.

Sounds like it could be a dirty or bad flame sensor.
When the burner lights ,there is a flame sensor in the flame and it is suppose to sense the flame and send a signal back to the control board which will keep the gas valve open, if it gets dirty or is bad it doesn't send the signal back to the board and the board will shut the gas valve off and after three tries it will lock out the furnace and you have to reset it to get it to work again.
The flame sensor looks like a wire and it's in the flame usually it will get gas deposits on it, then it won't work.
You can clean this sensor with an extra fine piece of steel wool, but before you attempt to do this DISCONNECT ALL POWER TO THE FURNACE.

Furnace filter is black and sooty wall seem to be sooty


   By sealed unit you mean that the burner air comes from outside of the house?      You have checked the heat exchanger for cracks by removing the burners and looking with a mirror and flashlight, correct, or had a service tech so?
The furnace burners have enough air and are burning clean (blue) with just a tip of orange at the end? You bought the house new and the fireplace has never been used?  If it has been used to clean smoke for the house for whatwever reason I woudl start by havign the ducts cleaned.   Another possibility I have seen is insolation inside of ductwork breaking down.
