How do I start the heater?

First, follow all ventilation and safety information. Then, fill the fuel tank with kerosene or No.1 fuel oil, attach the fuel cap, and plug the power cord of the heater into a three-prong, grounded extension cord.

What should I do if the heater needs to be reset?

Unplug the extension cord from the outlet and wait 10 seconds (or two minutes if the heater has been running). Then, plug the extension cord into a standard 120 volt/60 hertz, three-hole, grounded outlet.

Q: What fuels can I use with the B70D and R70D heaters?

Only use kerosene or No.1 fuel oil to avoid the risk of fire or explosion. Do not use gasoline, naphtha, paint thinners, alcohol, or other highly flammable fuels. Heavy fuels such as No.2 fuel oil or No.2 Diesel should also be avoided.

WARNING: Use only kerosene or No. 1 fuel oil to avoid risk of ﬁre or explosion. Never use gaso- line, naphtha, paint thinners, al- cohol, or other highly ﬂammable fuels.

Do not use heavy fuels such as No. 2 fuel oil or No. 2 Diesel. Using heavy fuels will result in a clogged fuel ﬁlter and/or nozzle.

IMPORTANT: Use a KEROSENE ONLY storage container. Be sure storage container is clean. Foreign matter such as rust, dirt, or water will cause the ignition control assembly to shut down the heater. Foreign matter may also require you to clean fuel system often.

Follow the minimum fresh, outside air ventilation require- ments. If proper fresh, outside air ventilation is not provided, car- bon monoxide poisoning can occur. Provide proper fresh, out- side air ventilation before run- ning heater.

Provide at least a three-square-foot opening of fresh, outside air for each 100,000 Btu/Hr rating. Provide extra fresh air if more heat- ers are being used.

Example: A 70,000 Btu/Hr heater requires one of the following:

•a two-car garage door (16 feet wide open- ing) raised two inches

•a single-car garage door (9 feet wide opening) raised three inches

•two windows (30 inches wide opening) raised six inches
