Question about Procom ML300EBC Heater

1 Answer

Runs fine for 2-4 minutes then shuts down.. auto..

I couldn't provide a 3 feet head room it is at 16 inches. It seems like as soon as the internal fan kicks in it shuts down.. Is the thermocupal cooling and then shutting down ?? OR potentially O2 sensor given the high/clearance issue.. I have installed in my garage and would like to keep it higher to eliminate the kid hazard potential issue.. Spoke with an installer and they feel it is the clearance issue.. But, I am hopeing that is not the case.. Thoughts ???

How old is this heater? does flame stay on thermocouple? what is the make and model # then i can look up some manuals of the heater and maybe give you some thoughts of what is going on. clearance could be a problem but i don't think it is.

    how long do you run the heater before you turn on fan? I talked with a procom rep. he said you do need the 36" clearance since it is a vent free. i could not find that model # on there site. I would try to lower the heater and see if that makes a difrence.

My Dayton 110,000 btu kerosene torpedo heater... The fan kicks on for a couple secs then kicks off it seems as it's not getting any fuel what should I do

Could be the Flame out sensor cutting the power to the electrics and therefore the forced air fan. It forces the heater to shut off should the flame extinguish. It might also be the temperature limit control which also turns the heater off if the internal temperature rises to an unsafe level. If either of these two possibilities the unit may need a service.

When turning on My dyna pro 6500 heater. The fan will kick on for about 10sec then it will shut down and the red light will blink. How do I fix it

I have several of these in my shop. When they act up it is usually carbon deposits blocking the fire eye. This is a sensor that detects flame, if no flame is present it shuts down the whole heater. Remove the upper cover of the heater and attempt to start it, watch for 1- spark from the ignition sorce 2-fuel being sprayed from the atomizing nozzle 3-ignition of fuel. No spark bad spark plug or ignitor, no smell of fuel or small cloud of fuel, bad fuel filter, no fuel, bad fuel line, bad or plugged nozzle. There are several things that cause this but these are the three most common problems I encounter.

Fire stoppes and fan still runs

1st take a air gun and blow in the fan to clear of debris. 2nd make sure to push your reset button on the back by your fan. Last you can calibrate your flame/heat by removing the fan housing & you will find 2 set screws try a small 1/16 turn on them and try to run, should run better for you.

Gmh95/gch9 manual calls for 3 inch exhaust pipe?

furnaces must be vented EXACTLY as specified by the mfr or you WILL have problems - they spend a lot of time and money coming up with those specs. then design the furnace based on them.

Shuts down when fan kicks on

if it kicks out right away then it sounds like your fan motor is defective or possibly if the motor has a capacitor it could be defective,also does your receptacle have the ampacity to handle the unit?

Pilot lights fine, furnace fires up, when it turns off the pilot goes out

need to have at least 3 feet of vent out of the roof, if it is to low the coll air will cold soak down to the pilot and shut it down.

Toyo L-30 Start up noise

before the heater starts up, the combustion blower starts to purge the chamber of unburnt gases, then the solenoid pump, pumps fuel onto the burner mat, shortly thereafter the ignitor turns on and ignites the kerosene. what you are hearing is the combustion blower. its a small motor with a rather large vacuum impeller on it. it sounds like a jet engine when it first starts. there are two bearings on this motor shaft. yours evidently are dry - no lubrication. replace the motor or if you have the equipment purchase two sealed ball bearings and press them on the shaft.
