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 - ATMOSPHERIC HEATERS
With the heater on, remove the door and make a visu- al check of the pilot and burner. The flame should be blue with a

MILLIVOLT 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 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 serv- ice person at the time of installation and periodically checked thereafter. Refer to Pressure Switch Adjustment on pg. 37 of this manual).
SECTION 2 - CAUTION
Elevated water temperature can be hazardous. The U.S. Consumer Product Safety Commission has these guidelines:
1.Spa water temperatures should never exceed 104°F (40°C). A temperature of 100°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
4.Before entering the spa or hot tub, users should check the water temperature with an accurate ther- mometer; spa or hot tub thermostats may err in reg- ulating water temperatures by as much as 4°F (2.2°C).
5.Persons with a medical history of heart disease, cir- culatory problems, diabetes, or blood pressure problems should obtain a physician's advice before using 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.
