SECTION 3 / INSTALLATION INSTRUCTIONS
IMPORTANT NOTICE
These instructions are intended for the use of quali- fied 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 licensed. 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 accord- ing to these instructions.
WARNING:
Improper installation, adjustment, alteration,ser - vice or maintenance may damage the equipment, create a hazard resulting in asphyxiation, explosion or fire, and will void the warranty.
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
BASE INSTALLATION
Heater must be mounted on a level base, such as cement slab, cement blocks or other
CLEARANCES
ALL HEATERS
For clearances from combustible surfaces, see the chart below.
CLEARANCEFROMCOMBUSTIBLECONSTRUCTION
INDOORINSTALLATIONS:
Top*(Drafthood) - 30" Back - 6"
Front - Alcove Right
Vent - 6"Left
side) 6"
OUTDOORINSTALLATION:
Top* (Stackless top or outdoor stack) - Unobstructed
Back - 6"
Side - 6"
*Clearance from top of vent terminal.
When installed according to the listed minimum clearances 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 clearance 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 movement 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.
OUTDOOR HEATERS
These heaters are design certified for outdoor installation, when equipped with the approved tops des- ignated for outdoor use.
WARNING: The heater shall 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 some electrical components, and this would void the warranty.
WARNING: Do not install within 3 feet of a heat pump or an outdoor condensing unit. Strong air intake from these equipment can disturb the combustion process and cause damage or personal injury.
Utilize hollow concrete cinder blocks, align holes and leave ends open.
