LOCATING THE HEATER:
Locate the pool/spa heater in an area where leakage of the heat exchanger or connections will not result in damage to the area adjacent to the
heater or to the structure. When such locations cannot be avoided, it is recommended that a suitable drain pan, with drain outlet, be installed
under the heater. The pan must not restrict airflow. This heater must be installed at least (5) feet from the inside wall of a pool (in-ground or
above-ground)/spa/hot tub unless separated from the pool/spa/hot tub by a solid barrier. The heater must be installed such that the location of
the exhaust gas vent assembly outlet relative to adjacent public walkways, adjacent buildings, openable windows, and building openings com-
plies with the National Fuel Gas Code (ANSI Z223.1/NFPA 54) and/or CAN/CGA B149 installation codes.
1. Level surface for proper rain water draining and removal.
2. Suitable electrical supply line. See rating plate on the heater for electrical specifications. A junction box is not needed at the heater; con-
nections are made inside the unit electrical compartment. Minimum wire size to be selected per NEC.
3. Electric disconnect switch that will interrupt all power to the unit. This switch MUST be within line of sight of the heater.
4. The heater does not require additional vent piping when installed outdoors.
5. Do not install in a location where growing shrubs may in time obstruct a heater’s combustion air and venting areas.
6. Do not install this appliance under an overhang less than 72in from the top of the appliance. The area under the overhang must be open
on (3) sides.
7. Do not install the heater where water spray from ground level can contact the heater. The water could reach the controls causing electrical
damage.
8. Do not install under a deck.
9. Do not install within 24 inches of any outdoor HVAC equipment.
10. Do not install where water may run-off a roof into the heater. A gutter may be needed to protect the heater.
CAUTION:
Make sure the heater is not located where large amounts of water may run-off from the roof into the unit. Sharp sloping
roofs without gutters will allow massive amounts of rainwater, mixed with debris from the roof to be forced through the unit. Failure to fol-
low the instructions may result in property damage and void warranty.
11. Any enclosure around the heater must provide a combustion air vent large enough to accommodate input ratings of all gas appliances in
the enclosure. See AIR SUPPLY section for more detail
12. For minimum exhaust vent clearances for all building openings, including, but not limited to, vented eaves, doors, windows, or gravity in-
lets, see Figure 4.
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
.
OUTDOOR AND INDOOR INSTALLATION AND SERVICE CLEARANCES:
For both outdoors and indoors installations, the
installation clearances from combustible materials and service clearances shown in Table 3 and Figure 4
must be maintained. Do not
install heater in a closet or enclosed space (consult NFGC)

* If the heater is to be installed with vinyl siding behind or on the exhaust side of the heater, increase the clearance in Table 3 to 12
inches
to avoid poten al discolora on of siding.
** While the heater is designed for no clearance to combus ble surfaces, it is recommended to leave a small gap for non‐binding removal
of the top access panels.
