4.2. Clearances
AA
AVERTISSEMENT: Cet appareil doit être installé
conformément au National Fuel gas Code ANSI Z223.1, et
aux exigences de l’autorité competente.
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 ow.

Table C. Required Minimum Clearances from Combustible
Surfaces
Dégagements minimaux à assurer entre les parois de
l”appareil et les contructions combustibles: 6po (15.2 cm)
(côtés), 12po (30.5 cm) (arrière) et 30po (76.2 cm) (dessus).
When installed according to the listed minimum clearances
from combustible construction, the pool heater can be
serviced without removing permanent construction
around the heater.
However for ease of servicing, we recommend a
clearance of at least 18" (45.7 cm) on the rear. This will
enable the heater to be serviced in its installed location,
that is, without movement or removal of the heater.
Minimum clearance from drafthood to combustible
construction 6" (15.2 cm) from the vent.
Degagement minimal de 6 po (15.2 cm) requis entre le
coupe-tirage et une construction combustible. 2 po du
conduit de raccordement.
Clearances less than recommended 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.
It is possible to reduce the clearances to combustible
surfaces by protecting these surfaces as shown in table
10.2.3 of the National Fuel Code. See Table D.
