Forced Air Heater

[skyhightree1]

I was in my workshop running 2 forced air heaters and 1 ran fine the other would spark and smoke like crazy then light and go off about every 30 seconds and was spitting out kerosene then I noticed some was running out anyone ever have that happen ? I haven't used this unit over 2 hours worked fine 2 weeks ago but now its acting up anyone ever have that problem before? I will tinker with it tomorrow.

Photo sensor ? Normally when they get dirty or fail the unit will shut off, without all the excitement.

Its brand new do you think that could be it? When I ran it the first time it was kinda smelling like oil pretty bad and burned my eyes could a photo sensor cause that?

I thought you meant the unit had been operating 2 hours before the problem, not that it's a new unit with 2 hours total time. If both units are the same brand, bought at the same time, topped with the same fuel and you know there's no water in the fuel, I would take it back for exchange or refund.

You don't have to spend extra on karosene, red Diesle is fine now. They have cleaned it up so much it doesn't smoke or burn your eyes like it used to.

I bought them a year ago but today I looked on the back and theres slotted knobs on back of the unit/motor I turned them counter clockwise works like a champ I have no clue why its out of adjustment.

Thanks Jed that's really good to know. 8)

Sky if it goes to acting by running for awhile then shutting off you can take the fuel lines off at the burner and give it a few puffs of air with a blow nozzle don't give it much just a few quick bursts there is a screen or something in there that will get plugged and needs cleaned out happened to ours last week and works fine since I did this

AC thanks for the tip these kerosene forced air heaters seem a bit touchy. I am used to the propane units they seem to be not as troublesome. I took the cover off and watched it work and saw the electric arc constantly going and I couldn't believe that little fan blows out that much air. Before I adjusted it it smoked a lot and the end metal didn't get red now they glow red. How often do yall use those heaters?

 

[jedstivers]

We run one every day it's cold. Haul,it around and warm up frozen wells, frozen pipes under houses, tractors that won't start. It for getting the shop warm quick and on cold days it has to run quite a bit. Have run 10 gallons a day through it quite a few days.

Dag do yall have those really huge ones ? I only have the 75,000 btu models by mr heater. They heat up a 16x16 bay that's not insulated very well pretty quickly.

 

[jedstivers]

I think it's the middle size John deere one.

 

[skyhightree1]

oh ok I saw one that im sure it could heat a 100x100 building the business end was about as around as a wheel on my f250 I would hate to get to close to that bad boy.

I don't have the kerosense model, but I have the LP version of a forced air. Mine is 30k low and 75k high and compact. Heats my uninsulated 20x25 shop nicely.

I've seen some of the large kerosene one football fields. Those suckers look huge on TV and can only imagine their true size in person.

I had the same kind of problems with mine a couple of years ago. I changed some parts, blew through the fuel line with my finger over the end and couldn;t find the problem. Took it to a guy that works on them, it was the fuel line, tiny almost invisible crack that would work fine blowing through it but would leak a bit under suction.

heater acted up again this past week so I took it apart today and found the problem which was both fuel and air hose were cracked and dry rotted so I replaced the hose and works great. if any of yall have same systems check the hoses.
