Can I use another fuel besides kerosene?
Our kerosene forced-air heaters will run on multiple fuels such as K-1 kerosene, Jet A, #1 fuel oil, or #1 diesel oil. Please be advised that because of the additives contained in diesel fuel, additional ventilation will be required to disperse the added contaminants produced. Additional maintenance to the heater will also be required.
Can my heater run on Bio-Diesel?
No, this heater is not designed nor approved to run on bio-diesel.
Can I use kerosene from last season?
Kerosene breaks down over time. Never use kerosene that has been stored from one season to the next. Never store leftover kerosene over the summer. Using old fuel can damage your heater.
Can I mix diesel fuel and kerosene together?
In extreme temperatures, a blend of 70% diesel and 30% kerosene can be mixed to prevent gelling.
What are the minimum clearances required from combustibles?
| Model | Top | Sides | Front |
| 220SDR | 4 ft. | 4 ft. | 8 ft. |
If the flame goes out, will fuel continue to pump?
The heater uses a photocell to "see" the flame in the combustion chamber. Should the flame extinguish, the sensor will stop electrica current and the heater will shut off.
The power is turned off but the fan still runs.
This heater must cycle through a "Cool-Down Cycle" in which the fan continues to run for approximately 3 minutes to circulate air through the combustion chamber to cool it before shutting off completely.
Can I use an extension cord? If so, what size do I need?
Yes, you can use extension cords with your heater. Please use the right size extension cord as shown below:
6 to 10 feet (1.8 to 3 meters), use 18 AWG conductor wire.
11 to 100 feet (3.4 to 30.4 meters), use 16 AWG conductor wire.
101 to 200 feet (30.8 to 61 meters), use 14 AWG conductor wire.

The heater is making a spark but is not starting.
Be sure that the fuel bowl is full and not allowing any air into the fuel system. If it is drawing air, fuel delivery may be inconsistent. The fuel must be sprayed in a continuous atomized pattern to ignite.

How long will my heater run on a tank of fuel?
220SDR: 8 hour run time on a full tank of fuel on high. Using the thermostat will increase the run time significantly.

How much ventilation do I need to use my heater safely?
The standard is to always provide a fresh air opening in the heated space of at least 3 square feet (2,800 sq. cm.) for each 1000,000 BTU/Hr of heater output. For example, a 220SDR (220,000 BTUs/Hr) heater requires the following fresh air openings:
- A two-car garage door open 12 inches, or
- A single-car garage door open 18 inches, or
- Two 32" (thirty-two inch) wide windows to be open 18 inches.
