WARNING: Use only kerosene, #1/#2 diesel/fuel
oil, JET A or JP-8 fuels to avoid risk of fire or explo-
sion. Never use gasoline, oil drained from crank-
cases, 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
Fan
assembly to shut down heater. Foreign matter may also require
Guard
heater's fuel system to be frequently cleaned.

VENTILATION

WARNING: Provide a fresh air opening of at least
three square feet (2,800 square cm) for each 100,000
BTU/HR rating. Provide extra fresh air if more heaters
are being used. The minimum ventilation require-
ments must be followed to avoid risks associated
with carbon monoxide poisoning. Make certain these
requirements are met prior to operating heater.
Example: A 58.6kw (200,000 Btu/Hr) heater requires one of the
following:
• a two-car garage door [4.88 meter (16 feet) opening] raised
12.7 cm (5 inches)
• a single-car garage door [2.74 meter (9 feet) opening] raised
20.3 cm (8 inches)
• two, 76.2 cm (30 inch) windows raised 38.1 cm (15 inches)
