Wont fire after following start instructions

OK-- Let's go thru your trouble shooting steps, and what you found:

1.) Fuel: Sufficient, and right type?

2.) Has the unit fired and run before?-- What is different in sounds, or settings now?

3.) How does this unit ignite the fuel?-- With Spark, or with Glowing ignitor?
If Spark-- can you hear it sparking?

If Glowing ignitor, -- can you see the glowing? (in a darkened room..)

4.) Can you see that Kerosene is spraying at the nozzle?-- is the pattern correct?

5.) Have you check fuel and air pressure settings-- according to the manual?

After observing these details-- let us know what other clues you are observing now.

I'll be here to take you to the next step, if you like--- Just add your new comments in the 'respond' box-- they will send them to me for further follow-up.

I hava an All Pro 65,000 BTU heater. It was working fine a week ago. The igniter glows, fuel mists but doesn't light off then shuts down. Ideas?

I am sure you have confirmed that the fuel is fresh and good, no water in it, etc.--
It is kerosene, not #2 Diesel fuel, right?

And the shutting down is good, if the flame does NOT ignite--- :-)
So we have to figure out why the fuel is not getting hot enough to ignite?

Question-- is the oil spray passing close enough to the ignitor?
And this unit does NOT use SPARK to ignite?, correct? --
for most of these heaters have spark ignition.. I am learning all the time, too!

How about checking the fuel pressure. and the air -- is it correct?
Check with your manual how to check and adjust.

After testing these tings, let us know what you learned

I have a 60,000 btu kerosene heater its getting fuel and the glow plug turns on but still wont fire up n shuts down. what would cause this?

Well it is getting fuel but is it atomized in very small droplet form? If so is your igniter close enough to ignite the fuel? You see these spray a very fine conical mist under high pressure, if the mist is not defined or conical it sprays past the igniter. If it is fine and cone shaped it could be the positioning of your igniter. Please check both by removing the top section of the heater and watch what is going on in there. My thoughts are a bad nozzle and if you replace it pay attention to spray angle and GPH rating printed on the side of the nozzle.

Want light

first thing you should do is make sure that there is ignition whether by spark plug or hot surface igniter. If you have ignition then make sure that you have fuel spraying from the injector located beside the igniter.If you don't have ignition, chances are you have a bad igniter or spark plug. A failed transformer would be the last thing I'd conclude as bad.

Vogelzang kerosene heater will not ignite (no spark)

There is an igniter module and then the igniter electrodes (check the air gap) that produces the spark to start the fuel burning, both could be defective.

Heater turns on for a few seconds then goes out

Absolutely K1 or diesel can get old in a hurry, the ultra-low Sulphur diesel has been tinkered with so much that it turns to book varnish much faster than before 2010. Most of those heaters spray fuel past the igniters using a siphon much like a spray paint gun, the suction tube may have dry rot or a small air leak and it it takes but a tiny air leak to kill the siphon effect. Check the tube from the nozzle all the way down to the fuel tank or replace it if you're not certain it is not compromised or dry rotted.

Wat the hell is wrong with my dayton heater?170,000 btu oil fired...wont stay runnin?on shut down puffs like a mutha....

Most use a spark plug to ignite fuel it could need cleaning. You also could have water in fuel or dirt
check and clean ignitor/spark plug clean fuel line and nozzle, drain and clean tank Check for water in fuel by tilting unit to have a low corner siphon fuel from that corner after 1 hr inspect for water.

35000 reddy kerosene heater

My unit is a kerosene 35000 btu unit...just had similar issue.
It is very possible that the spark plug is
  1. fouled out (dirty)
  2. mis-gapped
take the top cover off, you will see the plug. There is a sheetmetal plate held on by two screws holding the ground, plug, and nozzle together. It is easier to just remove the plate (you will have problems with the plug nut if you don't).

remove the plug with a plug socket, probably 5/8.
I used brake parts cleaner to spray off the electrode of the plug then a wire brush to clean it.

check your plug gap...this might be crucial. my gap was specified on a label stuck on the inside of the bottom of the body. The plug on my unit was way too small. Adjust gap if necessary using feeler guages.

reinstall parts and plate. (I actually tack-welded the plug nut into place for ease of maintenance later). Note that the electrode needs to be a specific angle, relative to nozzle....probably diagrammed on the same label as the gap spec.

replace top and see if she'll fire up.

...last note...also might check your fuel pickup/filter. It is located behind the side panel in the unit

good luck...hope I have helped you
