AFTER START-UPFeel the inlet and outlet pipes. Outlet pipe should beonly slightly warmer than the inlet. It should not be hot.WARNING: Should overheating occur or the gassupply fail to shut off, turn off the manual gas control tothe appliance.VISUAL INSPECTIONWith the heater on, remove the door and make avisual check of the pilot and burner.The flame should be blue with a well-defined pat-tern.Fig. # 8144.0MAIN BURNER FLAMEPILOT BURNER FLAMEA yellow or ìfloatingî flame indicates restricted airopenings or incorrect orifice size. Should this occur,shut the heater off and contact your installer or gassupplier.WATER PRESSURE SWITCHA water pressure switch is provided in the heater toshut off the burners in the event that water supply to theheater is interrupted. It is very important to verify thatthe switch electrically opens and shuts off the gas valvewhen 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 andadjusted for proper operation by a qualified serviceperson at the time of installation and periodically checkedthereafter. Refer to pressure switch servicing instruc-tion in Section 4 of this manual).WARNING: Operation of the heater without water circu-lation will cause rapid and severe damage to the heater.6SECTION 2/CAUTIONElevated water temperature can be hazardous, andthe U.S. consumer Product Safety Commission recom-mends the following guidelines:1. Spa or hot tub water temperatures should neverexceed 104∞F (40∞C). A temperature of 100∞F (38∞C)is considered safe for a healthy adult. Specialcaution is suggested for young children.2. Drinking of alcoholic beverages before or duringspa or hot tub use can cause drowsiness whichcould lead to unconsciousness and subsequentlyresult in drowning.3. Pregnant Women Beware! Soaking in water over102∞F (39∞C) can cause fetal damage during thefirst three months of pregnancy, resulting in thebirth of a braindamaged or deformed child. Preg-nant women should stick to the 100∞F (38∞C)maximum rule.4. Before entering the spa or hot tub, users shouldcheck the water temperature with an accuratethermometer; spa or hot tub thermostats may err inregulating water temperatures by as much as 4∞F(2.2∞C).5. Persons with a medical history of heat disease,circulatory problems, diabetes, or blood pressureproblems should obtain a physicianís advice beforeusing pools or hot tubs.6. Persons taking medications which induce drowsi-ness, such as tranquilizers, antihistamines, or anti-coagulants, should not use spas or hot tubs.SECTION 3/MAINTENANCE AND CAREPROCEDURESTo be followed one month after start-up and thensemiannually.1.

Wet sootedsurfaces completely prior to cleaning. Do not use steelwire brush.2. Clean main burners and pilot burner of dust and lint.3. Inspect and operate all controls, gas valve andpressure relief valve.4. Make visual check of the burner and pilot flame.Flame pattern on the main burner and pilot isindicated in the previous illustration. Yellow flamemeans restriction of the air openings. Lifting orblowing flame indicates high gas pressure. Lowflame means low gas pressure. Should this occur,shut the heater off and contact your gas supplier orqualified service agency.4" Max.
