FUELS
WARNING: USE ONLY KEROSENE OR #1 FUEL OIL
TO AVOID RISK OF FIRE OR EXPLOSION. NEVER
USE GASOLINE, NAPHTHA, PAINT THINNERS,
ALCOHOL 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:
• clogged fuel filter and nozzle
• carbon build-up on spark plug
• the need of non-toxic anti-icer in fuel during very cold
weather
IMPORTANT:
Use a KEROSENE ONLY storage container.
Be sure storage container is clean. Foreign matter such as
rust, dirt or water will cause flame-out control to shut down
heater. Foreign matter may also require you to clean fuel
system often.
