WARNING - CALIFORNIA PROPOSITION
65: This product contains chemicals known to the
State of California to cause cancer, birth defects or
other reproductive harm.
WARNING: This unit contains refractory ceramic
fiber (RCF) insulation in the combustion chamber.
RCF, as manufactured, does not contain respirable
crystalline silica. However, following sustained
exposure to very high temperatures (>2192F), the
RCF can transform into crystalline silica
(cristabolite). The International Agency for Research
on Cancer (IARC) has classified the inhalation of
crystalline silica (cristabolite) as carcinogenic to
humans.
When removing the burners or heat exchangers,
take precautions to avoid creating airborne dust and
avoid inhaling airborne fibers. When cleaning spills,
use wet sweeping or High Efficiency Particulate Air
(HEPA) filtered vacuum to minimize airborne dust.
Use feasible engineering controls such as local
exhaust ventilation or dust collecting systems to
minimize airborne dust. Wear appropriate personal
protective equipment including gloves, safety
glasses with side shields, and appropriate NIOSH
certified respiratory protection, to avoid inhalation of
airborne dust and airborne fiber particles.
CAUTION: Verify proper operation after servicing.
NOTE: Minimum 18 AWG, 105°C, stranded wire
must be used for all low voltage (less than 30 volts)
external connections to the unit. Solid conductors
should not be used because they can cause
excessive tension on contact points. Install conduit
as appropriate. All high voltage wires must be the
same size (105°C, stranded wire) as the ones on the
unit or larger.

WATER CHEMISTRY
OTE: Corrosive water voids all warranties.
N
Chemical imbalance can cause severe damage to
our heater and associated equipment. Maintain your
y
water chemistry according to Table A. If the mineral
content and dissolved solids in the water become too
high, scale forms inside the heat exchanger tubes,
reducing heater efficiency and damaging the heater. If
the pH drops below 7.2, this will cause corrosion of the
heat exchanger and severely damage the heater. Heat
exchanger damage resulting from chemical imbalance is not covered by the warranty.
For your health and the protection of your pool equipment, it is essential that your water be chemically
balanced. The following levels must be used as a
guide for balanced water.
CAUTION: Free chlorine must not exceed 5 ppm
which can damage the heater and void the warranty.
• Occasional chemical shock dosing of the pool or
spa water should not damage the heater providing
the water is balanced.
• Automatic chemical dosing devices and salt chloinators are usually more efficient in heated water,
r
unless controlled, they can lead to excessive chlorine level which can damage your heater.
• Further advice should be obtained from your pool
r spa builder, accredited pool shop, or chemical
o
supplier for the correct levels for your water.
Automatic Chlorinators & Chemical Feeders
All chemicals must be introduced and completely diluted into the pool or spa water before being circulated
through the heater. Do not place sanitizing chemi-
cals in the skimmer. High chemical concentrations
will result when the pump is not running (e.g.
overnight).
Chlorinators must feed downstream of the heater and
have an anti-siphoning device to prevent chemical
back-up into the heater when the pump is shut off. See
Fig. 1.
NOTE: High chemical concentrates from feeders
and chlorinators that are out of adjustment will
cause rapid corrosion to the heat exchanger.
Such damage is not covered under the warranty.

Water Temperature Safety
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 may cause drowsiness which
could lead to unconsciousness and subsequently
result in drowning.
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 spas or hot tubs.
6. Persons taking medications which induce drowsiness, such as tranquilizers, antihistamines,
anticoagulants, or recreational drugs should not
use spas or hot tubs.
