OUTDOOR HEATER INSTALLATION (CONTINUED)
The following information is for heaters located outdoors, using a 2 ft (61 cm) long vent pipe stack.
WARNING
CARBON MONOXIDE GAS IS DEADLY – Exhaust from this pool heater contains carbon monoxide, a
dangerous, poisonous gas you cannot see or smell. Symptoms of carbon monoxide exposure or poisoning
include dizziness, headache, nausea, weakness, sleepiness, muscular twitching, vomiting and inability to
think clearly. IF YOU EXPERIENCE ANY OF THE ABOVE SYMPTOMS, IMMEDIATELY TURN OFF THE POOL
HEATER, LEAVE THE VICINITY OF THE POOL OR SPA AND GET INTO FRESH AIR IMMEDIATELY. THE POOL
HEATER MUST BE THOROUGHLY TESTED BY A GAS PROFESSIONAL BEFORE RESUMING OPERATION.
EXCESSIVE CARBON MONOXIDE EXPOSURE CAN CAUSE BRAIN DAMAGE OR DEATH.
Locate the heater in an open, unroofed area and on a level surface 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. See Figure 22.
It is recommended that a non-combustible base be a platform under the heater, not less than 100 millimeters (mm)
thick However, the heater is approved to be installed on a combustible surface. 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 476004, see Figure 23.
Note 1: DO NOT locate the heater where it is exposed to a prevailing wind. Note 2: Be sure the heater is level.

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 ofcials to determine installation requirements and specic installation restrictions of
the heater relative to propane storage tanks and lling equipment. Installation must meet the requirements
for the Standard for the Storage and Handling of Liqueed Petroleum Gases, CAN/CSA B149.2 (latest
edition) or ANSI/NFPA 58 (latest edition). Consult local codes and re protection authorities about specic
installation restrictions.
