AFTER START-UP
Feel the inlet and outlet pipes. Outlet pipe should be only slightly warmer than the inlet. It should not be hot.
WARNING: Should overheating occur or the gas supply fail to shut off, turn off the manual gas control to the appliance.
VISUAL INSPECTION
With the heater on, remove the door and make a visual check of the pilot and burner.
The flame should be blue with a well-defined pattern.
MAX
Fig. # 8205.2
Fig. # 8964.1
PILOT BURNER FLAME
A yellow or "floating" flame indicates restricted air openings or incorrect orifice size. Should this occur, shut the heater off and contact your installer or gas supplier.
WATER PRESSURE SWITCH
A water pressure switch is provided in the heater to shut off the burners in the event that water supply to the heater is interrupted. It is very important to verify that the switch electrically opens and shuts off the gas valve when water flow to the heater is interrupted. Otherwise, rapid and severe damage will likely occur to the heater. (The water pressure switch should be checked and adjusted for proper operation by a qualified service person at the time of installation and periodically checked thereafter. Refer to pressure switch servicing instruction in Section 4 of this manual).
WARNING: Operation of the heater without water circulation will cause rapid and severe damage to the heater.
SECTION 2/CAUTION
Elevated water temperature can be hazardous, and the U. S. Consumer Product Safety Commission recommends the following guidelines:
1.Spa or hot tub water temperatures should never exceed104°F(40°C). Atemperatureof100°F(38°C) is considered safe for a healthy adult. Special caution is suggested for young children.
2.Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness and subsequently result in drowning.
3.Pregnant Women Beware! Soaking in water over 102°F (39°C) can cause fetal damage during the first three months of pregnancy resulting in the birth of a brain-damaged or deformed child. Pregnant women should stick to the 100°F (38°C) maximum rule.
4.Before entering the spa or hot tub, users should check the water temperature with an accurate thermometer; spa or hot tub thermostats may err in regulating water temperatures by as much as 4°F (2.2°C).
5.Persons with a medical history of heart disease, circulatory problems, diabetes, or blood pressure problems should obtain a physician's advice before using pools or hot tubs.
6.Persons taking medications which induce drowsiness, such as tranquilizers, antihistamines, or anticoagulant, should not use spas or hot tubs.
SECTION 3/MAINTENANCE AND CARE PROCEDURES
To be followed one month after start-up and then semi-annually.
1.Inspect top of heater and drafthood for soot, a sticky black substance around finned tubes and "V" baffles),andopenfluegaspassageways.Anyvisible soot should be cleaned for proper operation.
CAUTION: Soot may be combustible. Wet sooted surfaces completely prior to cleaning. Do not use steel wire brush.
2.Clean main burners and pilot burner of dust and lint.
3.Inspect and operate all controls, gas valve and pressurereliefvalve.

POOL & SPA WATER CHEMISTRY
Chemical imbalance can cause severe damage to your heater and associated equipment. Maintain your waterpHbetween7.4and7.8andtotalalkalinitybetween 100 and 150 p.p.m. If the mineral content and dissolved solids in the water become too high, scale forms inside theheatexchangertubes,reducingheaterefficiencyand also damaging the heater. If the pH drops below 7.2, the heater will be severely damaged. This will result in corrosion of the heat exchanger. Heat exchanger damage resulting from chemical imbalance is not covered by the warranty.

SECTION 3 / INSTALLATION INSTRUCTIONS
CALIFORNIA PROPOSITION 65 WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.
IMPORTANTNOTICE
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 personnelmayberequiredbysomestatestobelicensed. 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.
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.
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 recommended 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 oftheNationalFuelGasCode,ANSI Z223.1andNational 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.
BASEINSTALLATION

*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 removing 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 designated 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.
