Re: Scheu Heater problem

Sounds like the fuel nozzle filter is clogged. remove it and blow air through it backwards or just replace the nozzle.

There are four possible answers to this problem, if the heater starts normally, runs for a few seconds or minutes and the shuts down but was still running normally at the time of shut down, this could be caused by the photocell, also known as the flame out control. This safety device may be failing, shutting down even though the heater is working normally, check the operation of the photocell. The second cause may be partial fuel filter blockage, the heater is effectively starving itself of fuel, so the flame blows out, hence the puff of smoke, and then shuts down on the safety cut out. Third cause, if this model has a compressor at the rear of the motor, the problem could be low pump pressure, caused by wear or contamination of the carbon blades, this would cause the wrong amount of fuel to be syphoned up, with weak fuel mix the heater may blow itself out and shut down. The fourth cause, perhaps indicated by the puff of white smoke, is contamination of the fuel with water, water will cause the white smoke and also is indecated by white residues or a power like substance on the end plate of the heater which glows red hot when burning.

Heater runs a few minutes then blows smoke and cuts off

Are you using the old fuel from last year? If so, drain and clean the tank. Replace with fresh fuel and replace the fuel filter. Check or replace the air filters. Check your ignitor for proper operation. Test again. Good luck.

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

Reddy heat/scheu kerosene space heater no ignition

Typical kero heater uses either a spark ignition or a hot surface. The hot surface igniter is very fragile. A small bump may break the elements. Flame is detected by a photocell, signal is sent to the lockout relay board. Change the igniter costs about 50 bucks.
