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
SPACE HEATERS ARE BEING USED. THE MINIMUM
VENTILATION REQUIREMENTS MUST BE
FOLLOWED TO AVOID RISKS ASSOCIATED WITH
CARBON MONOXIDE POISONING. MAKE
CERTAIN THESE REQUIREMENTS ARE MET
PRIOR TO OPERATING SPACE HEATER.
Example: A 200,000 Btu / Hr (58.6kw) space heater
requires one of the following:
• a two-car garage door [16 feet (4.88 meter) opening]
raised 5 inches (12.7 cm)
• a single-car garage door [9 feet (2.74 meter) opening]
raised 8 inches (20.3 cm)
• two, 30 inch (76.2 cm) windows raised 15 inches
(38.1 cm)
FUELS
WARNING: USE ONLY KEROSENE, #1/#2 DIESEL/
FUEL OIL, JET A OR JP8 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 space 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 space heater.
Foreign matter may also require space heater’s fuel system
to be frequently cleaned.
