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 valve 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.

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. Other- wise, 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 recom- mends the following guidelines:

1.Spa or hot tub 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 drowsi- ness 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, antihista- mines, or anticoagulants, should not use spas or hot tubs.
