Question about Heating & Cooling

Open Question

Pulsing Burner My 150,000 BTU Kerosene Heater pulses, about 80-100 times a minute a minute, resulting in shooting out orange flame. I suspect a bad pump, but before I invest in a new pump and the trouble to change it I'd like an expertspinion. I've cleaner the air intake filters, Changes spark plugs to that recommended by the manufaturer. Start up ignition is not a problem only pulsing at it operates. I suspect I am not burning fuel efficientlt, the orange flame and a strong oder of unburnt kerosene in the air to the point of eye irritation.

When you say that the fan starts then stops I assume you also mean that the burner starts and stops. If this is correct and the unit is more than a couple of years old you probably need to change the filter in the back and set the pump pressure. Both the filters and the gauges to set the pressure can be found at along with a good explanation as to why you need the gauges. The pressure is set by bleed air pressure and must be exactly 3.5 psig. The gauge is the only accurate way to do it. The filters clog and change the pressure. When the difference is enough the unit will not run. Now with that said there are several other things which you should check. Check the fuel tank for water. Remove any you find. Remove the cover on the right side as you look at the unit from the front and remove the circuit board. Check for cracked connections. If you find any resolder them and reattach the board. That should take care of the unit and get you back to making heat. Let me know if you need anything else.

I have an All Pro 150000 btu kerosene / diesel torpedo heater. It runs for a few minutes and then starts sputtering, shooting flames and smoke. What causes this problem?

First thing is to download the service manual.

You need to make sure the filters are clean and that you are getting the proper air pump pressure.

If the units starts up and runs good and slowly goes out it will normally be due to a lack of fuel getting to the nozzle. When there is not enough fuel being delivered to the nozzle from either a clogged fuel filter of dirty air pump output filter the unit will slowly shut down from lack of fuel.

If the unit shuts down while it is running properly and the nose come is orange then you probably have a problem with a photocell or the flame out control.

If you have other questions you can contact our service department at 269-685-4125 at extension 224

My all pro 150000 btu heater sputters, shoots flames and smoke. what causes that?

The first thing to check would be the fuel filter from the tank to the nozzle.

Then check the input and output filters on the back of the pump housing.

Here is a link to a service manual.

I have a 60,000 b.t.u. kerosene heater that runs 3-5 minutes than shuts off unplug for 10 seconds fires right back up and does the same thing

More than likely either the photocell is going bad.... or your flame is not strong enough... if the nose of your heater barely glows orange then your heater is not burning hot enough... if your heaters nose has a healthy orange glow then your photo cell is going bad and needs to be replaced OR if your heater has a circut board then you could possibly have a bad relay or a bad board.... if the nose of the heater barely has a glow to it while it is running then try turning your pump pressure up... there is an adjustment screw in the plastic cover of your pump which is on the back of the electric motor... it takes a straight screw driver head to adjust..... if that screw is all the way in and your heater is still barely burning then you need to tear the pump apart and clean the wheel and the 4 reeds that go in the weel.... tear off the plastic pump cover that houses your filters.... then take the metal face plate off that is behind the plastic cover (usually 6 screws) now your wheel should be exposed.... those 4 little reeds should FREELY slide in and out of the slot... if they dont.... then take them out of the wheel and take a scratch pad and clean both the reeds and the slots on the wheel they go in until they freely slide up and down... hope this helps

The heater is not proving the flame...and shutting down on safety...
Check the flame sensor and all connections of the ground from the burner to the ignition control...
The control may also be bad...

I have a 100,000 btu reddy heater, and every time I turn it on, it runs for about 5 minutes, then stops, then I have to push the reset button and start it again. Can you tell me where to start? thanx

If it actually ignites and burns but shuts off either the flame sensor is bad (or dirty) or the control is bad. I would verify the flame sensor is clean and had good electrical connections to the controller for starters.

Torpedo Reedy heater 150,000 BTU starts & fires but after 2-3 minutes of heating , it shuts down, after it is off for about 3 minutes it will start & fires but then shuts down , each time it shuts...

There is a flame sensor inside the burner unit. The sensor is like a photo cell that must see the light of the flame or it will tell the burner control to stop the power. You need to see if there is a soot film on the lense of the sensor and make sure the sensor is aimed straight. If the sensor is clean and aimed straight (and the problem persists) then there may be a clogged nozzle that is giving a poor flame and the sensor does not see a good flame therefore shuts down the unit. If the nozzle is at fault, then you for sure need to replace the oil filter. New nozzles are $4-8 and the size & spray angle is stamped on the nozzle. If there is still a problem, then you need to see if the pump is giving approx. 100psi pressure, then finally (the last step) would be to replace the burner control $60. Goodluck< Macgivor
