The nozzle is not adjustable, but the pressure is adjustable, and must be, infact, set to factory specs .

I have a used B115. I put kerosene in it. Plug it in, it will run about 5 sec then shut off, kicking out the reset button. Push in the reset and it runs for a shorter time and cuts off again. Have checked...

Remove the top of the heater. Watch out for the fan and turn the heater on. Use a flashlight to look for fuel spraying from the nozzle. If it isn't, check the nozzle for blockage and the fuel filter. If fuel is spraying, make sure the igniter is working. The reset kick out because the flame sensor isn't detecting any flame or is dirty.

The heater will try to start but keeps flaming out. I have put in new fuel and cleaned the filter and the spray tip. the fan will come on and the fuel will fire but it will only stay on for a few seconds...

Try cleaning the photo eye flame sensor. It is the black rubber boot close to the burner. Remove it and you can see the sensor down inside. Clean it with a soft cloth or a cotton swab and some alcohol. Also check the air line for cracks and check for tightness where the air line connects to the fan motor and the fuel nozzle. If the hose is stretched there, try trimming a little off the end so it will fit tighter. Check the fuel line for the same thing where it connects to the fuel filter and fuel nozzle. Let me know what you find and don't forget to rate the answer.

I have a B100g master torpedo style heater if you take the cover off it fires right up if you leave the cover on the fan just runs but no flame I cleaned all hoeses and filters plug now iam stumped

Well usually when this occurs it is a sign that the nozzle is plugged or just plain wore out. So I want you to try cleaning the nozzle by removing it and soaking it in carb cleaner, use a Q-tip and clean off the external parts and use a tooth pick to clean out any clogged ports. Then take a blow gun and compressed air and blow high pressure air thru the nozzle several times backwards and forwards. Some heaters depending upon year of manufacture have a screen in behind the nozzle if yours does clean it as well, they like to corrode. My older model has the screen my new model does not so it does vary in different years. place the nozzle back in and test fire your heaterwith the top section loosely screwed on, two will work. If your problem is still the same unfortunately it is time for a new nozzle, pay attention to spray angle and GPH rating usually printed on the side of the nozzle.Good luck

Replaced blower motor on my heater now it runs without top cover install cover and it flames out

This is pointing to a bad or dirty fuel nozzle, ultimately you should replace the nozzle pay attention to spray angle and GPH rating printed on the nozzle. You can try cleaning it with compressed air and a blow gun,or carb cleaner and Q-tip and tooth pick. I soak mine in carb cleaner and use the Q-tip to clean around the out side with out damaging it, and tooth pick in case there is any obvious pieces of dirt stuck in the nozzle, then blow it out with high pressure air to finish. If you have cleaned it before in this manner it may just be time to replace it. Good luck!!

I have ready heater 150, 000 btu, the fan is blowing strong and there is constant fire comeing from sparkplug , but its not igniting. What could be wrong.

No fuel!! Several things can cause this, empty fuel tank, dirty fuel filter, plugged screen in the nozzle assembly,or plugged nozzle. So lets clean up the fuel system by first removing the top section of the heater and exposing the burner tray. Remove the tray and locate the fuel nozzle, remove the nozzle, now they say you can not clean them, I say with a q-tip, tooth pick and carb cleaner you can just be careful not to damage the nozzle. Behind the nozzle is a screen assembly these corrode at times so clean it up too. Below the nozzle assembly is the flame sensor, clean this with windex and a soft terry cloth rag, make sure it will have a clear unobstructed view of the flame.Put the nozzle assembly back together, and now inspect the fuel line for cracks, holes,and dry rot replace if necessary. Trace the lines down to the side where they come thru the case. Remove the side cover and locate the fuel line and in line filter, remove the filter. Cleaning this is easy you need a compressor and blow gun, all you do is blow air backwards thru the filter and instantly its clean. Inspect fuel lines and reassemble. Now make sure that you have clean fuel in your tank, and there is no water in it as well.Plug it in and you should now be heating like new. If not it could be your fuel pump!

My heater keeps shutting off after about 30 seconds. I hit the reset button and it happens again. Any thoughts or suggestions?

Several thoughts on this heater Fuel delivery system, the fire eye sensor or dirty intake filter. These are the most common problems that I run in to with these heaters. Start by taking off the top half of the heater tube. Find the nozzle unscrew it and clean the screen in behind the nozzle, inspect the nozzle for corrosion or damage. If you see any restriction replace the nozzle pay attention to spray angle and GPH rating this is printed on the nozzle. They say you should not clean the nozzle because you can damage them, well carb cleaner q-tips and a tooth pick seem to work well and not cause damage. Locate the flame sensor these get a dirty lens and can shut down heaters as well. Try cleaning with windex and soft terry cloth rag, works wonderful.Back to fuel system inspect the fuel line look for holes dry rot or restrictions.Remove the screws on the side cover to expose the wiring and fuel line with filter to fuel tank. Remove the filter and clean it I use compressor and an air blow gun and blow backwards thru the filter cleans it right out.Inspect it and the lines reassemble and at the back opf the heater is a sponge type filter remove it. This is a foam filter wash it out, dry it real good put it back in and fire it up. Take your time pay attention to detail and this should help your ailing heater.

Heater runs for 30 sec then shuts off blows smoke and gives e-1 error code

I am not to sure of the trouble codes on Mr.Heater but this is usually a fuel related problem. My routine maintenance is remove top half of heater and clean fuel system from nozzle back to the tank.Remove nozzle,clean the screen behind the nozzle they corrode over the summer sometimes inspect the nozzle for corrosion or damage. Inspect lines back to pump then to filter. The filter can be cleaned out with compressed air and a blow gun blowing air thru the filter backwards. Now check the fuel line to the tank and make sure it is submerged in the fuel. Before putting the top on locate the fire sensor and give it a quick cleaning with windex and soft terry cloth rag. Put your heater back together and check air filter to pump clean it and fire away. This works 90 percent of the time. Good luck!

Heater will not stay on rm60 reddy heater

When you say the heater is coming on does it actually ignite or is the motor just running until the safety circuit kicks it off? The air pump on you heater should blow at 3.5 to 4 psi which runs up to the nozzle which is a venturi which sucks the fuel out of the tank. The motor will generally run for 20 to 30 seconds trying to ignite. If the flame sensor does not sufficient flame during the time it shuts the motor off. Check these items and let me know what you find.

When i turn on the heater it just blows smoke

according to desatech who makes reddy heat, the air compressor on the back of the fan should put out no more than 3.5 psi to the nozzle. you could also check the air path through the combustion chamber. sounds to me that the nozzle isn't atomizing the fuel but its coming out in a stream. the nozzle is supposed to make a conical pattern if the air pressure is correct.
