INSTALLATION
Installation Codes
Installations must be in accordance with local, state,
provincial, and national codes, laws, regulations and
ordinances. In the absence of local codes, installations
must be in accordance with the latest editions of the:
• National Fuel Gas Code, ANSI Z223.1/NFPA 54
• National Electrical Code, ANSI/NFPA 70
• For Canada only: CAN/CGA B149 installation Code
(B149) and CSA C22.1 C.E.C. Part 1 and Part 2
Clearances
The required minimum clearances from combustible
surfaces are shown in Table C below.
When installed according to the listed minimum clear-
ances from combustible construction, the pool heater
can be serviced without removing permanent con-
struction around the heater.
However for ease of servicing, we recommend a clear-
ance of at least 24" in the front, and at least 18" on the
rear. This will enable the heater to be serviced in its
installed location, that is, without movement or
removal of the heater.

Fig. 3: Alternate Method for Providing a Non-
Combustible Base
Clearances less than these may require removal of the
heater to service either the heat exchanger or the
burner tray. In either case, the heater must be installed
in a manner that will enable the heater to be serviced
without removing any structure around the heater.
Base Installation
Heater must be mounted on a level base, such as
cementable slab, cement blocks or another non-com-
bustible surface. An alternate method for providing a
base for combustible floors is illustrated. Heaters may
not be installed on carpeting.
Outdoor Installation
NOTE: This heater is design-certified for outdoor
installation when equipped with the approved top(s)
for outdoor use.
WARNING: The heater should not be located in an
area where water sprinklers, or other devices, may
cause water to spray through the cabinet louvers
and into the heater. this could cause internal rusting
or damage electrical components, and void the
warranty.
WARNING: Do not install within 3 feet of a heat
pump or an outdoor condensing unit. strong air
intake from this type of equipment can disturb the
combustion process and cause damage or personal
injury
NOTE: The heater should not be located in an area
where possible water leakage will 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
adequate drainage, be installed under the heater.
The pan must not restrict combustion air flow.
