READ THIS MANUAL BEFORE INSTALLATION OR OPERATION.
WATER CHEMISTRY
NOTE: Corrosive water voids all warranties.
Chemical imbalance can cause severe damage to your
heater and associated equipment. Maintain your water chemistry according to Table 1. 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.
WATER CHEMISTRY TIPS
• Occasional chemical shock dosing of the pool or spa water
should not damage the heater providing the water is bal-
anced.
• Automatic chemical dosing devices and salt chlorinators
are usually more efficient in heated water, unless controlled, they can lead to excessive chlorine level which can
damage your heater.
• Further advice should be obtained from your pool or spa
builder, accredited pool shop, or chemical 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 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 Figure 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.
3. Pregnant Women Beware! Soaking in water over 102°F
(39°C) may 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 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.

When ordering parts, specify the model and serial number
of the heater. When ordering under warranty conditions,
specify the date of installation. Records of the installation
must be provided, when requested, to substantiate a claim.
Debits for defective replacement parts will not be accepted and will only be replaced in kind per the manufacturer's
standard warranties.
INSTALLATION
INSTALLATION CODES
Installations must be in accordance with local, state,
provincial, and national codes, laws, regulations and ordinances. In the absence of local codes, installations must be
in accordance with the latest editions of the:
• National Fuel Gas Code, ANSI Z223.1/NFPA 54
• National Electrical Code, ANSI/NFPA 70
• For Canada only: CAN/CGA B149.1 and .2 installation
Code (B149.1 and .2) and CSA C22.1 C.E.C. Part 1 and
Part 2
NOTE: The heater should not be located in an area
where possible water leakage will result in damage
to the area adjacent to the heater or to the structure.
When such locations cannot beavoided, it is recommended that a suitable drain pan, with adequate
drainage, be installed under the heater. The pan
must not restrict combustion air flow.
CLEARANCES
The required minimum clearances from combustible surfaces are shown in Table 3.
BASE INSTALLATION
Heater must be mounted on a level base, such as
cementable slab, cement blocks or another non-combustible
surface. An alternate method for providing a base for combustible floors is illustrated. Heaters may not be installed on
carpeting.
Table 3. Required Minimum Clearances from Combustible
Surfaces.
*Clearance from top of vent terminal.
When installed according to the listed minimum clearances from combustible construction, the pool heater can be
serviced without removing permanent construction around
the heater.
However for ease of servicing, we recommend a clearance of at least 24" in the front, and at least 18" on the rear.
This will enable the heater to be serviced in its installed location, that is, without movement or removal of the heater.
Clearances less than these may require removal of the
heater to service either the heat exchanger or the burner tray.
In either case, the heater must be installed in a manner that
will enable the heater to be serviced without removing any
structure around the heater.
OUTDOOR INSTALLATION
NOTE: This heater is design-certified for outdoor
installation when equipped with the approved top(s)
for outdoor use.
WARNING
THE HEATER SHOULD NOT BE LOCATED IN AN AREA
WHERE WATER SPRINKLERS, OR OTHER DEVICES, MAY
CAUSE WATER TO SPRAY THROUGH THE CABINET
LOUVERS AND INTO THE HEATER. THIS COULD CAUSE
INTERNAL RUSTING OR DAMAGE ELECTRICAL COMPONENTS, AND VOID THE WARRANTY.

WARNING
DO NOT INSTALL WITHIN 3 FEET OF A HEAT PUMP OR
AN OUTDOOR CONDENSING UNIT. STRONG AIR INTAKE
FROM THIS TYPE OF EQUIPMENT CAN DISTURB THE
COMBUSTION PROCESS AND CAUSE DAMAGE OR PERSONAL INJURY.
HEATER WITH OUTDOOR STACKLESS TOP
Heaters must not be installed under an overhang of less
than 3 ft from the top of the heater. Three sides must be
open in the area under the overhang. Roof water drainage
must be diverted away from heaters installed under overhangs with the use of gutters.
• For U.S. installations, the point from where the flue prod-
ucts exit the heater must be a minimum of 4 ft below, 4 ft
horizontally from, or 1 ft above any door, window or gravi-
ty inlet into any building. The top surface of the heater
shall be at least 3 ft above any forced air inlet, or intake
ducts located within 10 ft horizontally. See Figure 6.
• For installations in Canada, pool heaters shall not be
installed with the top of the vent assembly within 10 ft
below, or to either side, of any opening into the building.
Refer to the latest revisions of CAN/CGA-B149.1 and
B149.2
OUTDOOR HIGH-WIND TOP
NOTE: The outdoor high-wind top is optional equipment and does not come standard with the heater.
Use the following part numbers.
P/N 004301 (Green) P/N 011558 (Gray)
HIGH WIND CONDITIONS (OUTDOOR UNITS ONLY)
In areas where high winds are frequent, it may be necessary to locate the heater a minimum of 3' from high vertical
walls, or install a wind-break so the heater is not in direct
wind current.
In areas of daily high winds, it may be necessary to
replace the outdoor stackless top with a stack adapter in
combination with a wind-resistant/weather-proof outdoor
stack. See Figure 4.
The outdoor stack serves the same function as the lowprofile stackless top and should be installed in accordance
with the same clearance requirements. Follow the installation
instructions provided with the High Wind Kit for installation.
Figure 4. Outdoor High-Wind Top.
INDOOR INSTALLATION
The heater is design-certified for indoor installation when
equipped with the approved drafthood.
NOTE: 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 for details. Minimum allowable space is shown
on the nameplate. Follow the installation instructions provided with the Indoor Drafthood Kit for installation.

COMBUSTION AND VENTILATION AIR
(INDOOR UNITS ONLY)
The heater must have both combustion and ventilation air.
Minimum requirements for net free air supply openings are
one opening that is 12 inches from the ceiling for ventilation,
and one opening that is 12 inches from the floor for combustion air as outlined in the latest edition of the National Fuel
Gas Code, ANSI Z223.1(Canada-CAN/CGA-B149.1 and
B149.2) and any local codes that may have jurisdiction.
ALL AIR FROM INSIDE THE BUILDING
Each opening shall have a minimum net free area of 130
sq. in.
ALL AIR FROM OUTDOORS
When air is supplied directly from outside of building,
each opening shall have a minimum net free area of 33 sq.
in.
CAUTION
COMBUSTION AIR MUST NOT BE CONTAMINATED BY
CORROSIVE CHEMICAL FUMES WHICH CAN DAMAGE
THE HEATER AND VOID THE WARRANTY. DO NOT
STORE CHLORINE, BROMINE, BAQUASIL OR ACID IN
THE SAME ROOM AS THE HEATER.
VENT PIPING
Vent piping the same size as the drafthood outlet is recommended, however, when the total vent height is at least 10
ft (drafthood relief opening to vent terminal), the vent pipe
size may be reduced as specified in the National Fuel Gas
Code, ANSI Z223.1 (Canada - CAN/CGA-B149.1 and
B149.2). As much as possible, avoid long horizontal runs of
vent pipe and too many elbows. If installation requires horizontal runs, the vent pipe must have a minimum of 1/4 in. per
ft rise and should be supported at not more than five foot
intervals. Plumbers tape, criss-crossed, will serve to space
both horizontal and vertical piping. Gas vents supported only
by the flashing and extending above the roof more than five
feet should be securely guyed or braced to withstand snow
and wind loads. We recommend use of insulated vent pipe
spacers through the roof and walls.
For protection against rain or blockage by snow, the vent
pipe must terminate with a vent cap which complies with local
codes or, in the absence of such codes, the latest edition of
the National Fuel Gas Code, ANSI Z223.1 (Canada CAN/CGA-B149.1 and B149.2).
The discharge opening must be a minimum of 2 ft vertically from the roof surface and at least 2 ft higher than any
part of the building within 10 ft. Vent stack shall be at least 5
ft in vertical height above the drafthood outlet. The vent cap
location shall have a minimum clearance of 4 ft horizontally
from, and in no case below, unless a 4 ft horizontal distance
is maintained, from electric meters, gas meters, regulators
and relief equipment.

Figure 7. Vent Piping Requirements.
The weight of the vent stack or chimney must not rest on
heater drafthood. Support must be provided in compliance
with applicable codes. The heater top and drafthood must be
readily removable for maintenance and inspection. Vent pipe
should be adequately supported to maintain proper clearances from combustible construction.
Type "B" double-wall or equivalent vent pipe is recommended. However single-wall metal vent pipe may be used
as specified in the latest edition of the National Flue Gas
Code ANSI Z223.1 (Canada - CAN/CGA-B149.1 and
B149.2).
GAS CONNECTIONS
Gas piping must have a sediment trap ahead of the
heater gas controls, and a manual shut-off valve located outside the heater jacket. All gas piping should be tested after
installation in accordance with local codes.
