There should be some sort of fire eye on this, either a visually operated sensor of a thermocouple that is reading the temperature of the flame. If it senses no flame it will shut the unit off so you don't get poisened by fumes.Does it re-set when you try and start it again or do you have to push the reset button, either way it needs to be re-set before operating again. I suspect that this sensor is causing your problems. These units also have fuel pumps, this may also cause the problem, hard for me to tell without seeing the unit.

My ready heater 100,000 will run for app. 5hrs then flame out and blow smoke or unburned fuel the same several times pressure is right


If the heater continuously has a 5 hour run-time check to see if the fuel pickup tube goes to the bottom of the tank. If broken, cracked, or shortened the fuel will stop being picked up when air is sucked rather than fuel.

There is a sensor in the tube that is a safety feture. it is a snap disc it maybe faulty, it is reading that the tube is to hot and shutting down, it cools and works again, check snap disc and also they need pleanty of fresh air.

Reddy heater 115,000 btu heater runs for about ten minutes then shuts off does this model have a thermostat or carb that might need adjusting????


A heater with this problem is probably the hardest to determine the cause. There is no carb orn thermostat to adj. If it uses a spark plug ignitor I would check the plug gap and make sure it is at an angle to the nozzle. If it has Hot Surface Ignition this will not be the problem. I would then check the fuel filter in the dip tube in the tank and the pump pressure. I should be about 4.5 psi. I would also remove the nozzle and replace it or at least blow it out backwards withlcompressed air to clean it. If all these items fail to correct the problem I would replace the flame sensor. Let me know what you find out or if you have any questions.

Kerosene Portable Forced Air heater comes on, runs awhile


The unit should have a fuel & air filter. Check that both are clear. Inside the burner tube, there will be a photo-cell, if the lense is dirty it will shut the flame off. The photo-cell needs to see the flame. You can carefully and gently, clean the lens with a tissue, soft cloth, or Q-tip. Please let me know how its coming along.

Pro 110, runs 10 min., blows white smoke ,shuts off


the first thing you need to do is go back to useing K1 kerosene, diesel fuel not only burns dirty but also has a tendency to gel up in cold weather which could be makeing it hard for the heater to draw the proper amount of fuel. To reset the pressure you will need a gage, it should run at about 6-7 psi. you can order a pressure gage from mr. heater online, they are by far the cheapest I have found as they are the actual manufacturer or call 1-800-251-0001
