propane will accumulate and the possibility of a fire is present.
Propane gas is scented and its strong odor is readily detectable.
Never strike a match or bring any flame or create an electric
spark in an enclosure when you smell propane gas. Ventilate the
area thoroughly, move the heater outside, find and correct the
source of the leak before attempting to light any appliance. If
you are unsure of these instructions evacuate immediately and
call for help.

with the heater, follow the shut down instructions and return
the heater to the dealer or address given on last page.
D. LEAK DETECTION: Before each use of the heater check all
fittings and connections with a soap solution to be sure there
are no leaks. NEVER, NEVER USE ANY FLAME FOR LEAK TEST.
E. CONNECTING HEATER TO PROPANE CYLINDER: Always
connect the heater to the cylinder in the outdoors or in a well
ventilated area. NEVER connect this heater to a cylinder near an
open flame.
F. USE OF HEATER: Always operate the heater in heating position
(see Figure 6) or cooking position (see Figure 5) on a level
noncombustible surface. NEVER place the propane cylinder on
its side when operating the heater. In cooking position cylinder
must be 30 degrees from horizontal.
WARNING
