Feel the inlet and outlet pipes. Outlet pipe should be
only slightly warmer than the inlet. It should not be hot.
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.
4" MAX
Fig. # 8205.2
MAIN BURNER FLAME
Fig.# 8964.1
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 service person at the time of installation and periodically
checked thereafter. Refer to Pressure Switch
Adjustment on pg. 37 of this manual).
WARNING:
Should overheating occur or the gas
supply fail to shut off, turn off the manual gas control
to the appliance.
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.
WARNING:
Operation of the heater without water
circulation will cause rapid and severe damage to
the heater.
Fig. # 9438

SECTION 3 - MAINTENANCE AND
CARE PROCEDURES
To be followed one month after start-up and then semiannually.
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.
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 7. 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.
5. On indoor heaters, clean room intake openings to
ensure adequate flow of combustion and ventilation air.
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.
2. Your pump strainer basket may be full. If so
remove debris.
CAUTION:
Soot may be combustible. Wet sooted
surfaces completely prior to cleaning. Do not use
steel wire brush.
3. Your filter may be dirty. If so, backwash or clean
filter. (To tell if your filter is dirty, look to see if the
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.
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
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 diagram page 21.
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.
CAUTION:
Combustion air must not be contaminated by corrosive chemical fumes which can damage
the heater and void the warranty.

COLD WEATHER OPERATION
IMPORTANT FREEZE INFORMATION
MODERATE CLIMATE: Heater operation can contin-
ue during short-term cold spells. When temperatures
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.
WINTERIZING THE POOL & SPA HEATER
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 plug 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.
3.
For ASME Heaters only: Disconnect compression
fittings from the pressure switch and return header
that connects to the 1/4" copper tube and allow the
tube to drain.

ARNING: Indoor heaters require a drafthood that must be connected to a vent pipe and properly vented to
the outside. Failure to follow this procedure can cause fire or fatal carbon monoxide poisoning.
INDOOR HEATER INSTALLATION
The heater is also design-certified for indoor installation when equipped with the approved drafthood.
For Canada, indoor installation is restricted to an enclosure that is not occupied and does not directly communicate with an occupied area. Refer to the latest edition of CAN/CGA-B149.1 and B149.2 for specific requirements. Locate heater as close as is practical to a chimney or gas vent. Heater must always be vented to the outside. See Vent Piping section (pg. 17-18) for details. Minimum allowable space is shown on the nameplate.
OUTDOOR STACK / INDOOR STACK
NOTE: The outdoor and indoor stacks are optional equipment and do not come standard with the heater.
