This is a propane, direct-fired heater. Propane
is heavier than air. If propane leaks from a
connection or fitting, it sinks to the floor, col-
lecting there with the surrounding air, forming
a potentially explosive mixture. Obviously,
propane leaks should be avoided, so set up
the propane supply with utmost care. Read
Propane/LP Safety, page 4 for additional
information about detecting propane leaks.
Leak check new connections or reconnections
with a soap and water solution and follow all
connection instructions herein. Also, ask your
propane dealer for advice on the propane ap-
plication and supply installation and ask them
to check it if there are any questions.

ence of other people the user is responsible
