OUTDOOR INSTALLATION
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 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.
HEATER LOCATION AND CLEARANCES – OUTDOOR
• 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
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
around the heater must be open on three sides. DO NOT, under any circumstances, install the heater under ANY deck.
For minimum exhaust vent clearances for all building openings, including but not limited to vented eaves, doors,
windows, gravity air inlet, see
In Canada, the heater must be installed with the top of the vent at least 10 feet (3m)
below, or to either side of, any opening into a building.
Orient the heater for convenient access to the water connections and the gas and
electrical connections.
Note: Check local building codes for installing the heater from any property
line set back requirements (see page 17 for installation illustration).
CAUTION: If installing the heater next to or near an air
conditioning unit or a heat pump, allow a minimum of 36 in. (91.4
cm) between the air conditioning unit and the heater.
CAUTION: DO NOT install the heater within 5 ft. (1.5M ) of
the inside surface of a pool or spa, unless it is separated by a
solid fence, wall or other permanent barrier.
