IMPORTANT NOTICE
These instructions are intended for the use of qualified
personnel only, specifically trained and experienced in
the installation of this type of heating equipment and
related system components. Installation and service
personnel may be required by some states to be li-
censed. If your state is such, be sure your contractor
bears the appropriate license. Persons not qualified shall
not attempt to fix this equipment nor attempt repairs
according to these instructions.
CODE REQUIREMENTS
NOTE: The heater should not be located in an area
where possible water leakage will result in damage to
the area adjacent to the appliance or to the structure.
When such locations cannot be avoided, it is recom-
mended that a suitable drain pan, adequately drained,
be installed under the appliance. The pan must not
restrict combustion air flow.
Installation must be in accordance with local codes, or,
in the absence of local codes, with the latest edition of the
National Fuel Gas Code, ANSI Z223.1 and National
Electrical Code, ANSI/NFPA 70, and for Canada, the
latest edition of CAN/CGA-B149.1 and B149.2, and
Canadian Electrical Code, CSA C22.1 Part 1 and Part
2.
BASE INSTALLATION
Heater must be mounted on a level base, such as cement
slab, cement blocks or other non-combustible surface.
An optional non-combustible base is available for all
models.
CALIFORNIA PROPOSITION 65 WARNING: This product contains chemicals known to the State of California
to cause cancer, birth defects or other reproductive harm.
An alternative method for providing a base for combustible
floors is illustrated below. Heaters must not be installed
on carpeting.

SECTION 3 - INSTALLATION INSTRUCTIONS
WARNING:
Improper installation, adjustment, alteration, service or
maintenance may damage the equipment, create a
hazard resulting in asphyxiation, explosion or fire, and
will void the warranty.
Fig. # 8148.1
Utilize hollow concrete cinder blocks, align holes and
leave ends open.
When installed according to the listed minimum clear-
ances from combustible construction materials, the
Raypak pool heaters can still be serviced without remov-
ing permanent structural construction 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
water connection side. This will enable the heater to be
serviced in its installed location, that is, without move-
ment or removal of the heater.
Clearances less than these (6" minimum), 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.
