WARNING
Risk of asphyxiation if exhaust is not correctly vented. Follow venting instructions exactly when installing heater. Do not
use a draft hood with this heater, as the exhaust is under pressure from the burner blower and a draft hood will allow exhaust
fumes to blow into the room housing the heater. Exhaust venting to the outdoors is required for all outdoor shelter installations.
WARNING
Risk of explosion if a unit burning propane gas is installed in a pit or other low spot. Propane is heavier than air. Do
not install the heater using propane in pits or other locations where gas might collect. Consult your local building code officials
to determine installation requirements and specific installation restrictions of the heater relative to propane storage tanks and
filling equipment. Installation must meet the requirements for the Standard for the Storage and Handling of Liquefied Petroleum
Gases, CAN/CSA B149.2 (latest edition) or ANSI/NFPA 58 (latest edition). Consult local codes and fire protection authorities
about specific installation restrictions.

WARNING
Risk of fire and explosion if installed at floor level in an automotive garage or near gasoline or flammable liquid storage.
Gasoline fumes are heavier than air and will settle to floor level in closed spaces. Gasoline fumes and spilled gasoline or other
volatile liquids (such as some paints and varnishes) will travel across the floor and can be ignited by a gas appliance.
