endanger safety of persons in area.
To ensure personal safety, installation and repair of propane
fuel supply systems must be performed only by qualifi ed
propane system technicians. Improperly installed and
maintained propane equipment could cause fuel supply
system or other components to malfunction, causing gas
leaks.
Observe federal, state and local laws governing propane
fuel, storage, and systems.
Explosive Fuel can cause fi res and severe
burns.
If a gaseous odor is detected, ventilate area
and contact an authorized service technician.
