HEATER CLEARANCES – OUTDOOR
IMPORTANT!
• In an outdoor installation it is important to ensure water is diverted from overhanging eves with a proper
gutter/drainage system. The heater must be set on a level foundation for proper drainage.
• This unit shall not be operated outdoors at temperatures below -20
o
F.
If the heater is located under a roof overhang, there must be at least three (3) feet (1m) of
clearance between the bottom of the overhang and the top of the heater exhaust vent, see Figure

OUTDOOR INSTALLATION
For heaters located outdoors, using the built-in stackless venting system.
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 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 restrictions.
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.
To avoid damage to the electronic components in the heater, take care to prevent prolonged exposure to driving 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 disconnect the power to it until the weather has moderated.
In areas subject to hurricanes or very high winds, purchase the Bolt Down Bracket Kit, P/N 460738.
