Reddy Heater 170T works fine with the cover off but will not ignite with the cover on.


First, heaters with Hot Surface Ignitor technology MUST have the air pump pressure set to factory specs. The onboard computer will not allow any deviation. Proper fuel delivery depends on it.

Now, if the pump pressure is correct, there are no leaks between the pump and the nozzle and no vac leaks on the fuel line, the 90% of the time the problem is a worn nozzle. Desa recommended annual replacement of the nozzle simply because of the wear factor.

When i take the top of my reddy hearter off it will start right up . but when it is on it will not start>


A worn nozzle creates a spray pattern, where a good nozzle creates a fog.With a coarse spray pattern poor combustion results in an off colorflame, . The photocelldoesn't like the color, sends a signal to the computer whichshuts everything down. That's the job of the electronics. On HSI ( hot surfaceignitor) heaters it is all about correct flame color , not just flame. The part where you write "If I remove the cover again it runsfine" is a symptom of a bad, worn, or restricted nozzle (generally).Remember- the ignitor only stays red for 5 seconds, then the flame keeps itselflit. The nozzle's pattern is a cone. Lift the lid & the pattern widens(aerodynamics) - replace the lid and the cone narrows & possibly distortsthen the flame goes out. This nozzle rule will only apply if everything is correct as far asfuel delivery applies. The pump pressure must be correct- not almost correct.Set the pressure with a low-pressure gauge that registers12-15 psi max. A gaugewith a higher scale just will not read close enough to satisfy the system. If the pressure is not correct, the aboverule will not apply. Instructionsfor setting the pressure can be viewed at http://reddyparts.com/pressure.htm. In addition, a fan can cause the same problem if damaged ormis-matched to your specific model. I must mention that any air leaks onthe pressure side (or vacuum leaks on the fuel line, for that matter) betweenthe pump and the nozzle will create a rich/lean mixture at the combustionchamber, creating an off-color flame.

When unit fires i get a short burst of fuel then nothing


Clean, waterless fuel and correct air pump pressure are absolutely a requirement for a good running heater. Drain the tank, set the air pump pressure. Your problem could be more serious, such as losing air between the pump & nozzle, a worn nozzle, or a restricted fuel filter.

  4. Restricted fuel flow
  5. Air loss between the pump & the nozzle
  6. Vacuum loss between the tank & nozzle

NO FUEL AT NOZZLE


FOUND THAT THE FUEL HOSE AND AIR PUMP HOSE HAD BEEN REVERSED AT THE NOZZLE-PUMP HOSE NEEDS TO BE CLOSEST TO THE BLOWER HOUSING-I USED A VAC GAUGE TO TEST THE FUEL LINE-WHILE THE AIR PUMP WAS RUNNING-NO VAC-REVERSED LINES AND STARTED UNIT-ADJUSTED AIR PRESSURE-ALL IS WELL

REDDY HEATER 125T WON'T INGNITE


  1. Does the ignitor glow for 5 seconds when the unit is started?
  2. What is the air pump pressure reading?
These are the starting points for troubleshooting a heater that has an ingntor.

Answer these questions and maybe someone can get you started.

Won't light


Are the ignitors intact? In other words, does the element make a loop back to the ceramic portion. The purpose of the LED is to notify the user of a defective ignitor. The other possibility is a bad control board.

If the ignitor is intact, but no power coming from the board (ignitor only glows for 5 seconds), then the board is bad or the fuse is blown. You might want to test the photocell while you are at it.

You will need to locate the correct model numbers to order the correct parts. "170T" & "125T" are only part of the correct model designation.

Post back if you have further questions.
