OUTDOOR INSTALLATION INSTRUCTIONS
For heaters located outdoors, using the built-in stackless
venting system.
Risk of explosion if a unit burning propane
gas is installed in a pit or other low spot. Propane is heav-
ier 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 require-
ments of heater relative to propane storage tanks and fill-
ing equipment. Installation must meet the requirements of
the Standard for the Storage and Handling of Liquid
Petroleum
Gases, ANSI/NFPA 58 (latest edition) in the U.S., or
CAN/CSA B149.2 (latest edition) in Canada. Consult local codes
and fire protection authorities about specific installation restric-
tions.
Locate the heater on a level surface in an open area that
is protected from drainage or run-off. Install the heater in
an area where leaves or other debris will not collect on
or around the heater.
This heater is designed for outdoor installation. However,
to avoid damage to the electronic components in the
heater, take care to prevent prolonged exposure to dri-
ving sources of water (such as lawn sprinklers, heavy
roof runoff, hoses, etc.). Avoid operation in persistent,
extreme, moist or salty environments.
In extreme weather, shut down the heater and discon-
nect the power to it until the weather has moderated. In
areas subject to hurricanes or very high winds, purchase
the Bolt Down Bracket Kit, Part No. 460738.
