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.
Consult local codes and fire protection authorities about specific installation restrictions.

(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.
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 18.
Note 1: DO NOT locate the heater where it is exposed to a prevailing wind. Note 2: Be sure the heater is level.
