H-8012 PapaBurn FreeBurn ™ USED-OIL HEATER KIT

You won't believe the heat!
This is a tremendous heater, costing 1/3 the price of a commercial used oil heater having the same heating capacity, yet with higher efficiency!

• 10 to 15 hours assembly time • No welding required • Flue size 6"

This Used Oil Heater Kit is not UL approved
NOT FOR INDOOR RESIDENTIAL USE.

08043 Power Outage Control. Without the Power Outage Control, the pump will come back on as soon as power is restored after an outage. But since there is no fire, the oil will fill up the bottom of the heater and run out on the floor. With this control, when there is a power outage the oil and combustion air supplies are turned off until reset.

"Harold Electric.
I purchased a papaburn just over 2 heating seasons ago. I was a little leery about my purchase when the kit arrived. Almost sent it back. BUT now I wouldn’t get rid of it for anything...well almost anything.
We live in central NH and the stove heats a 6,000 sq ft welding shop. We have propane radiant heat for nites and weekend backup. In the worst of winter the shop gets to 55 degrees easily.. I am glad I found you on the Net.
Thanks again."

As in our other kits, the combination of fuel control, combustion air control, and a hot combustion chamber creates very clean burning. There is no filtering required, and you can fix just about everything in the kit yourself! The reservoir has a screen assembly to help keep larger material from plugging the suction strainer.

Made out of a 55 gallon barrel. Kit includes almost everything you need: Burner Control Package, Heat Exchanger Kit, (with 28 heat exchanger tubes and hardware), 1100 CFM Exchanger Blower, Air Plenums to direct air through the heat exchanger into your shop, and a 80-mesh Screen Assembly for your oil reservoir, plus detailed assembly instructions.

• You supply: barrel, flue pipe, and oil reservoir.

Note: This is a manual operated heater. You start it by preheating the combustion chamber with a 1/4 cup of karosene or diesel and wadded up newspaper. This will get it hot enough so the oil will start vaporizing and burn by itself. It runs continuously at whatever heat output you set by the speed control on the pump (it cannot be thermostatically operated). This heater is not intended to run unattended.

" I've used the brake drum burner 3 or 4 years, and found out I should have done this 25 years ago. It's a sweet heatin' machine that heats so good I have to open a door when the weather is in
the 30's. Sir I can't say enough about this burner kit, best money
I have ever spent."

Why build a Used Oil Heater instead of buying a commercial one?

H-8012 and H-8014 Advantages Compared to Commercial Units • Low initial cost - 1/4 to 1/3 the price of commercial heaters • Simple design • fewer components • fewer problems • Easy to troubleshoot - does not require a trained serviceman • No filtering needed - just strain the oil! • Larger range of oil viscosities • Simple means to get rid of antifreeze, used oil filters • No nozzle to plug • Synthetic oil can be burned when mixed with regular oils • Variable heat output • No air compressor required • Very high heat efficiency with our heater kits • Much lower yearly maintenance cost • Build and install it yourself Disadvantages Compared to Commercial Units • Does not operate off a thermostat • Not UL approved • Cannot be mounted from ceiling or wall • Combustion chamber needs cleaning every 25 to 50 hours of operation (Takes just a few minutes) • Must be started manually

Often asked Questions and Answers About our Waste Oil Burner and Heaters Kits
1. How heavy (weight-viscosity) of oil can I use? Normally, up to 90 wt or heavier can be used, especially if it is mixed with lighter weight oils. 2. Do I have to preheat the oil? No, but if the temperature is near zero outside, it helps to keep the oil warm enough to flow. 3. Can I use synthetic oil? Yes, if it is mixed with other non-synthetic oils. 4. How much filtering is required? None! A 80-mesh screen on top of the oil reservoir and an intake screen are all the straining needed. 5. Does the nozzle plug? There is no nozzle to plug! 6. Do I need to separate the water and antifreeze from the oil? Yes, because it is very hard to keep the water and antifreeze mixed with the oil so it will burn as it goes through. 7. What do I do with the water and antifreeze that I separate from the oil? We put the water and antifreeze in 1 gallon coffee cans next to the combustion chamber. The water vaporizes off and the rest of the vapors burn.* 8. What can I do with my used oil filters? You can do the same as the water and antifreeze. The heat from the combustion chamber will cause the oil to vaporize and burn off.* * Applies to H-8012A only-Use welding gloves or other heat protection for your hands and arms when handling the hot cans. 9. Can I burn diesel or solvents? Solvents and other liquids must be mixed with 3 or 4 parts of regular waste oil. Your local codes may not allow the burning of solvents. Diesel can be mixed in with the used oil, but not run straight. Liquids may separate over time, affecting performance. DO NOT attempt to burn gasoline or alcohol, or any other highly flammable liquids or materials, in this heater!!!! 10. Can I burn vegetable, peanut oil, or biodiesel? Yes, but some are harder to start, so may require more paper or wood chips during startup. The oil flow and combustion air settings will be different. The heat output will also be different from fossil fuels. 11. Can I gravity-feed waste oil to the heater? No, gravity feeding removes your control of fuel flow, affecting the mixture and cleanness of burning. 12. How long do the combustion chambers and barrels last? 8 to 10 years or longer. The very high heat is confined to the combustion chamber and the area right above it. The barrel and controls are protected with a high temperature insulation blanket. The heat exchanger tubes in the H-8012 kit we have been testing have shown little degradation in five years of very heavy use. If you are running the heater very hot, you may need to replace the heat exchanger tubes that are directly above the combustion chamber. The heat exchanger tubes are easy to replace when necessary. 13. How often do I need to clean out the combustion chamber? Frequency of cleaning depends on how dirty the oil is. Generally, once every 25 to 50 hours of use. This is simple, and takes only a few minutes. 14. Is there any smoke? There will usually be some smoke during preheat, which takes about 5 minutes. There should be no smoke after preheat. 15. Can I burn wood, too? We do not recommend it. And then only if you have a single barrel stove without a heat exchanger assembly (creosote in the heat exchanger from the wood would create a very dangerous fire hazard). A metal shield should be placed over the insulation blanket to protect it from the wood. Remove the burner controls and pipes, and cover the hole in the barrel with metal. 16. What do I need to change if I use something besides a 55 gallon barrel? The lengths of the combustion air tube and the fuel line would need to be adjusted. 17. How often do I need to clean the barrels? In order to maintain high efficiency in the heat exchanger, we suggest the heater should be cleaned 1-2 times each heating season. 18. Is this Used Oil Heater EPA approved? The EPA allows the use of used oil heaters through a regulatory exemption regarding hazardous waste. The exemption allows the use of such heaters under 500,000 Btu per hour. So Used Oil Heaters are EPA exempted, not approved.
