WARNINGS

• Use only kerosene or No. 1 fuel oil to avoid risk of fire or explosion. Never use

gasoline, naphtha, paint thinners, alcohol, or other highly flammable fuels.

• Fueling

a) Personnel involved with fueling shall be qualified and thoroughly familiar with

the manufacturer's instructions and applicable federal, state, and local regula-
tions regarding the safe fueling of heating units.

b) Only the type of fuel specified on the heater's data plate shall be used.
c) All flame, including the pilot light, if any, shall be extinguished and the heater

allowed to cool, prior to fueling.

d) During fueling, all fuel lines and fuel-line connections shall be inspected for leaks.

Any leaks shall be repaired prior to returning the heater to service.

e) At no time shall more than one day's supply of heater fuel be stored inside a

building in the vicinity of the heater. Bulk fuel storage shall be outside the struc-
ture.

f) All fuel storage shall be located a minimum of 25 feet from heaters, torches,

welding equipment, and similar sources of ignition (exception: the fuel reservoir
integral with the heater unit).

g) Whenever possible, fuel storage shall be confined to areas where floor penetra-

tions do not permit fuel to drip onto or be ignited by a fire at lower elevation.

h) Fuel storage shall be in accordance with the federal, state, or local authority hav-

ing jurisdiction.

• Never use heater where gasoline, paint thinner, or other highly flammable vapors are

present.

• Follow all local ordinances and codes when using heater.

• Heaters used in the vicinity of tarpaulins, canvas, or similar enclosure materials

shall be located a safe distance from such materials. The recommended mini-

curely fastened to prevent them from igniting or from upsetting the heater due to
wind action.

foot opening of fresh, outside air for each 100,000 Btu/Hr of rating. This heater
produces carbon monoxide, which is listed by the State of California as a reproductive
toxin under Proposition 65.

occur.
