Top 20 Reddy Heater-170,000 BTU Kerosene Deluxe - Page 6 Questions & Answers

Is fuel getting to the nozzle? With the top of the heater removed, use a flashlight to look for fuel spraying from the nozzle. If it isn't, check the fuel filter. Have you check you air pressure going to the fuel nozzle? The required pressure should be listed on the data plate of the heater. If you can't get the air pressure right, your air filter could be the problem. Let me know what you find if this doesn't fix it.

If it runs for awhile and then smokes and then shuts off, the problem is usually in the fuel system. If you have never serviced your unit, it may be time to do it. Most fuel tanks start sweating during the hotter times of the year. This moisture builds up and settles on the bottom of your tank. Your suction fuel line is real close to the bottom and the water in the fuel ends up spraying on the ignition plug or glow plug causing it to put out the flame and the units circuit board shuts down the unit because of a flame was not sensed. Check the fuel if it is not fresh, change it. Usually there is a drain in the bottom of the tank. Good luck.

Naturally, my first question: Is it getting fuel?

If not always start troubleshooting by checking the air pump pressure. The pump pressure is directly related to fuel delivery.

This is an unvented heater and the gases if trapped in an enclosed area will kill you!!

Pre-start checklist?

I assume the heater ran fine last season. If so, assume it will run fine this season. Simply remove the top cover, check the combustion chamber area for signs of visitors such as mice, wasps, dirt dobbers, etc. Remove debris.

We always drain the old fuel & start fresh.

Replace the top cover and fire it up. If it runs fine then leave it alone. If it won't continue to run troubleshoot and find the problem.

I assume you have removed the top cover and eliminated an obstruction against the fan blade. If so the problem is either a broken rotor (air pump) or a locked up motor, which is not serviceable. These are simple tasks and no special tools are required except a low pressure gauge.

Not sure what you are looking for, but you can use this most anywhere. but not in enclosed areas...being that this is an unvented heater is does produce harmful gases that can hurt you if they are kept in an enclosed area...
Use this only in well ventilated areas or if you are inside then make sure to keep windows open for fresh air to enter..

Most ready heaters have a fuel pressure setting on the back of the heater near the fan. There should be two small plastic covers, looking directly at the back, the one on the left can be removed and a pressure gauge installed. The one on the right is slotted for adjustment of pressure.

Take a look at :-

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Check the fuel filter on the units as well as the inlet and outlet filters on the back of the motor.

Watch the nose cone and see if the end starts to loose the glowing orange color before it quits.
If the unit slowly looses the color then you have a fuel problem but if the unit just quits at full heat then you could have a electrical problem.

Sears has repair shops that could take a look and repair it for you, since I don't have a zip code I can't give you a exact place to go. normally if they don't start it's due to a faulty therm switch inside the heater where the flame blows out, it's not to difficult to fix, if you can give me a model number I can get a diagram for you to show you how to do this let me know.
