AFTER START-UP
4” MAX
MAIN BURNER FLAME
Feel the inlet and outlet pipes. Outlet pipe should be
only slightly warmer than the inlet. It should not be hot.
ARNING: Operation of the heater without water
W
circulation will cause rapid and severe damage to
the heater, and will void the warranty.
ARNING: Should overheating occur or the gas
W
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 visual check of the pilot and burner. The flame should be
blue with a well-defined pattern.
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.
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 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 anticoagulants, should not use spas or hot tubs.

SECTION 3 - MAINTENANCE AND
CARE PROCEDURES
2. Your pump strainer basket may be full. If so
emove debris.
r
WARNING: Check the heater for possible rodent
ests after long periods of non-use.
n
To be followed one month after start-up and then semi-
nnually.
a
1. Inspect top of heater and drafthood for soot, a
sticky black substance around finned tubes and
"V" baffles, and open flue gas passageways. Any
visible 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
pressure relief valve (if equipped).
4. Make visual check of the burner and pilot flames.
Flame pattern on the main burner and pilot is illustrated on page 6. Yellow flame means restriction
of the air openings. Lifting or blowing flame indicates high gas pressure. Low flame means low
gas pressure. Should the latter occur, shut the
heater off and contact your gas supplier or qualified service agency.
3. Your filter may be dirty. If so, backwash or clean
ilter. (To tell if your filter is dirty, look to see if the
f
filter pressure will be higher than usual).
4. The pump may have lost its prime and be running
dry. Check the pressure on the filter. If there is no
pressure; then you are not moving water (or your
gauge is broken). Try to get the pump to run at its
normal flow rate.
5. Check flow switch operation and paddles (“F” pad-
dle on 268 or “A” paddle on 408).
POOL & SPA WATER CHEMISTRY
Chemical imbalance can cause severe damage to
your heater and associated equipment. Maintain
your water chemistry according to the chart on page 2.
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.
AUTOMATIC CHLORINATORS AND
CHEMICAL FEEDERS
5. On indoor heaters, clean room intake openings to
ensure adequate flow of combustion and ventilation air.
CAUTION: Combustion air must not be contaminated by corrosive chemical fumes which can damage
the heater and void the warranty.
6. Keep area around heater clear and free from combustible materials, gasoline and other flammable
and corrosive vapors and liquids.
IF HEATER WILL NOT FIRE:
If you have no electrical power, it may be that your
"circuit breaker" has tripped. Try re-setting it.
If you have electrical power but the heater will not fire
check the following or see Troubleshooting section:
1. The time clock must be in the "ON" position.
All chemicals must be introduced and completely diluted into the pool or spa water before being circulated
through the heater. Do not place sanitizing chemicals
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 plumbing diagrams on page 22.
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.

COLD WEATHER OPERATION
DRAIN
WINTERIZING THE POOL & SPA HEATER
IMPORTANT FREEZE INFORMATION
MODERATE CLIMATE: Heater operation can contin-
e during short-term cold spells. When temperatures
u
are between 0° and 32°F, flow (continuous pump
operation) must be maintained.
CAUTION: Do not use the heater to maintain water
temperatures just above freezing or for freeze protection. When heater is used during freezing weather,
care must be taken to avoid freeze-ups. Continuous
pump operation is a must. Additional protection may
be required. The heater is not warranted against
freeze-ups.
COLD CLIMATE: Prolonged operation with water
temperatures below 50°F is not recommended.
When starting the heater with water temperatures
below 50°F, operate the heater continuously until
higher temperatures are reached. Operating the
heater for prolonged periods with pool water below
50°F can seriously damage the heater, and is not covered by the warranty.
For cold climate areas, please follow the winterizing
procedures listed.
Heaters installed outdoors in freezing climate areas
may be shut down for the winter. Observe the following procedure for winterizing the heater:
1. Turn off gas valve, manual gas valve, and electrical supply to the heater.
2. Open drain valve located on the inlet/outlet header, (under water pipes). Remove the heat
exchanger inspection panel on the side opposite
water piping to gain access to the drain plug on the
return header. Open drain plug on return header.

Ambient Temperature Rating of Heater Components
Electronic Ignition Heater*-32°F to + 175°F
*Requires 120 or 240VAC Power Supply
Atmospheric heaters:
Rated inputs are suitable for up to 2,000 feet elevation. For elevations above 2000 feet, reduce input 4% for
each 1,000 feet above sea level, as high elevation reduces combustion performance.
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.
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.
