FUELS
WARNING: Use only kero-
sene, #1/#2 diesel/fuel oil, JET
A or JP-8 fuels to avoid risk
of fire or explosion. Never
use gasoline, oil drained from
crankcases, naphtha, paint
thinners, alcohol or other highly
flammable fuels.
Use only kerosene, #1/#2 diesel/fuel oil, JET A
or JP-8 fuels. Heavier fuels such as No. 2 fuel
oil or No. 2 diesel fuel may also be used but will
result in:
• noticeable odor
• additional fuel filter maintenance
• the need for nontoxic, anti-icer additives in very
cold weather
Do not use fuels heavier than No. 2 grade or
heavy oils such as oil drained from crankcases.
These heavy oils will not ignite properly and will
contaminate the heater.
IMPORTANT: Use a KEROSENE ONLY (blue)
or DIESEL ONLY (yellow) 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 heater. Foreign
matter may also require heater's fuel system to be
frequently cleaned.
