If your heater has been installed correctly, operating the heater is an easy task. The upper front panel of the
heater contains the control center that allows you to turn the heater On or Off and adjust the temperature settings for the pool or spa. The temperature range is factory set from 65°F (18°C) to 104°F (40°C). See figure
above for location of toggle switch to turn the heater On and Off. Section 4 of this manual contains more details
about the use of the controls in the Control Adjustments subsection (page 26).
BEFORE START-UP
BURNERS
Clean main burners and air louvers of dust, lint
and debris. Keep heater area clear and free from
combustibles, flammable liquids and chemicals. Do
not obstruct the flow of combustion and ventilation air.
WATER
Water must be flowing through the heater during operation. Ensure that the system is filled with water and
that the pump is operating.

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.
IMPORTANT NOTICE
These instructions are intended only for the use by qualified personnel, specifically trained and experienced in the installation of this type of heating equipment and related system components. Installation

WARNING: 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.
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 Chapter
10 of the National Fuel Gas Code, ANSI Z223.1 (Canada - CAN/CSA-B149). 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 roofs and walls. Another option for
installation that requires horizontal runs is using the D-2 power vent kit option.

The D-2 Power Vent operates with a positve vent static pressure and with a vent
gas temperature that prevents excessive condensate
production in the vent, and
as such, is a CATEGORY III
appliance.
For more information consult the D-2 Power Vent manual, (Catalog No. 6000.57.1).
The unit, when installed as directed, is capable of operating in applications such as through-the-wall venting and
reduced horizontal and vertical vent pipe sizes in new and current installations. The unit is factory-wired for 240
VAC, with capability of rewiring for 120 VAC.
For protection against rain or blockage by snow, the vent pipe must terminate with a vent cap which complies
with the local codes or, in the absence of such codes, to the latest edition of the National Fuel Gas Code, ANSI
Z223.1 (Canada - CAN/CSA-B149).

unless a 4 ft horizontal distance is maintained, from
electric meters, gas meters, regulators and relief
quipment.
e
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/CSA-
B149).
GAS SUPPLY 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.
NOTE: With venting application of two or more
heaters, contact the factory.
CAUTION: The heater and its manual shut-off valve
must be disconnected from the gas supply during any
pressure testing of that system at test pressures in
excess of 1/2 psi (3.45 kPa). Dissipate test pressure
in the gas supply line before reconnecting the heater
and its manual shut off valve to gas supply line. FAILURE TO FOLLOW THIS PROCEDURE MAY DAMAGE THE GAS VALVE. OVER PRESSURIZED GAS
VALVES ARE NOT COVERED BY WARRANTY. The
heater and its gas connections shall be leak tested
before placing the appliance in operation. Use soapy
water for leak test. DO NOT use open flame.
NOTE: Do not use Teflon tape on gas line pipe thread.
A pipe compound rated for use with natural and
propane gases is recommended. Apply sparingly only
on male pipe ends, leaving the two end threads bare.
SUPPLY PRESSURES
A minimum of 6 in. WC and a maximum of 14 in. WC
upstream pressure under load and no-load conditions
must be provided for natural gas. A minimum of 12 in.
WC and a maximum of 14 in. WC are required for
propane gas under load and no-load conditions.

Gather the loose items that were shipped with the
heater. They will be as shown below:
The components should be assembled onto the
inlet/outlet header of the unit as shown below.
The heater must be located so that any water leaks will
not damage the structure of adjacent area. High temperature 2" plastic pipe (CPVC) may be threaded
directly into the header flanges. This is not the same
as the Schedule 80 PVC pipe which is also gray. PVC
may be used immediately after the supplied CPVC
adapters.
O NOT use petroleum-based assembly fluids (such
D
as petroleum jelly or lubricating oil). If assembly lube is
required, use a silicon base such as AquaLube etc.
UNITHERM GOVERNOR OPERATION
CAUTION:
The patented Unitherm Governor is a thermostatic
mixing valve specifically designed to maintain constant heater internal temperature between 105° and
115°F despite continually changing flow rates from
the filter and changing pool temperatures. This narrow range is needed to prevent damaging condensation on the burners which will occur if the heater runs
for any length of time below 100°F. It is also needed
to inhibit scale formation in the tubes by maintaining
temperatures well below accelerated scaling temperatures.
Once all components are in place and installed properly, the water connections will appear as shown
below:

AUXILIARY BYPASS VALVE ADJUSTMENT
In addition to the Unitherm Governor, a built-in automatic bypass valve is provided in the in/out header.
While the Unitherm Governor responds to the changes
in water temperature in the heater, the internal bypass
valve automatically responds to changes in water pressure in the piping system. Proper amount of water flow
s maintained through the heater under varying pres-
i
sures dictated by the conditions of the pump and filter.
To set bypass: With clean filter, adjustment is made by
feeling the inlet and outlet pipes at the heater. Outlet
pipes should be slightly warmer than inlet and comfort-
ble to the touch. If pipe is hot, close bypass; if cold,
a
open bypass.
PRESSURE RELIEF VALVE INSTALLATION
To conform to local building codes, it may be necessary to install a pressure relief valve. A 3/4" pressure
relief valve, having a capacity equal to the BTUH output of the model to be installed, is recommended for
this heater. The maximum acceptable pressure relief
valve setting is 125 psi.
EXTERNAL AUXILIARY BYPASS VALVE
(Where Required)
An auxiliary bypass valve should be used when flow
rates exceed 125 GPM. Usually a high-performance
pump size larger than two horsepower will exceed this
flow rate. This valve is required to complement the
function of the automatic bypass valve, particularly
when starting the heater in winter or early spring when
the spa or pool temperature is below 50°F. It also
serves to eliminate needless pressure drop through
the heater and accompanying reduction in the flow rate
to the spa jets, etc.
From Heater To Heater
To Pool/ From Pool/

NOTE: To avoid water damage or scalding due to
valve operation, drain pipe must be connected to valve
outlet and run to a safe place of discharge. Drain pipe
must be the same size as the valve discharge connection throughout its entire length and must pitch downward from the valve. No shut-off valve shall be
installed between the relief valve and the drain line.
Valve lever should be tripped at least once a year to
ensure that waterways are clear.

PLUMBING—WATER CONNECTIONS
Single Pool Heater
Installation
Multiple Pool Heater
Installation
The heater requires water flow and positive pressure to fire and operate properly. It must therefore be installed
downstream of the discharge side of the filter pump. A typical installation is plumbed as follows:
1. The inlet side of the filter is plumbed directly to the discharge side of the filter pump;
2. The outlet side of the filter is then plumbed to the inlet of the heater; and
3. The outlet of the heater is plumbed to the return line to the pool or spa. The pump, filter and heater are thus
plumbed in series (Salt generators and chemical feeders must be down stream of the pool heater).
Plumbing from the heater back to the pool or spa must not have any valves or restriction that could prevent flow
when the pump is operating.
CAUTION: An additional source of heated water, e.g. a solar system, must be connected to the main line
ahead of the heater inlet pipe in order for it to act as the primary heat source. If the primary system provides
adequate heat to maintain set-point, the heater will not fire. Be advised that the control panel will then display
sensed water temperatures downstream of the primary heating system, rather than the temperature of the
water exiting the pool.
Heater must be located so that any water leaks will not damage the structure of adjacent area.

REMOTE CONTROL INSTALLATION AND OPERATION
CAUTION: Before installing remote controls to the heaters, read the following:
The digital thermostat model is remote-ready in most cases. The digital liquid crystal display (LCD) shows the
actual pool temperature, operating status, and service codes (See examples below). The touch pad on the control panel allows you to select the desired pool or spa temperature. It also indicates when a remote system is
ontrolling the heater by displaying Remote in the display. When connecting the heater to a remote system,
c
identify whether it is a two- or three-wire remote system. Select the appropriate instruction listed below to properly install the remote to the heater.

REMOTE OPERATION
The heater is equipped with the ability to work with
external remote controls. The supplied 7-pin remote
wiring connector supplies power out to either a toggle
switch or the switch contacts of a third party remote.
The remote works by either making or breaking the circuit created by the remote wiring. Typically, a remote
does not supply power to the heater, it only provides a
switching function to turn the heater On or Off. If your
remote is supplying its own voltage to the heater,
it will not work with this heater and may damage
the digital circuit board.

ACTIVATING THE REMOTE
To activate or deactivate the remote function, follow
these steps:
Press and hold the UP and DOWN arrow buttons for
3 to 5 seconds.
The second line of the display will alternate even
when the unit is off (“No Demand”).
For operation of the heater using the onboard thermostatic controls with a time clock, see the “Time Clock /
Fireman’s Switch” section.
NOTE: When in remote operation, the keypad
mode and temp buttons are disabled.
Note: Electrostatic Discharge (ESD) damage can be caused by
direct or indirect contact with the wiring or circuit board. When
one walks to the heater area, an electrostatic charge accumulates on the body. Contact of a finger allows the body to discharge, possibly causing device damage. This damage can be
limited if the service person discharges himself, following ESD
preventive/removal practices, and holds on to the heater enclosure for 5 seconds before proceeding.

TIME CLOCK/FIREMAN’S SWITCH
To operate the heater with a time clock, connect the
imer to the fireman’s switch connection in the heater’s
t
wiring. The time clock should be of the dual switch
type and set to shut off the call for heat to the pool
heater 15 to 20 minutes prior to shutting down the pool
ump. The fireman’s switch connection is located on
p
the 14-pin header connected to the digital control
board. Splice into the red wire jumper tagged “Where
necessary add “Fireman’s” switch circuit here” to connect the time clock. The fireman’s switch connec-
tion must be a dry contact and must not supply
power to the heater. Powering the fireman’s
switch connection externally may damage the
heater, and is not
covered by warranty.
Do not exceed 50ft of total wiring using 18 AWG
stranded copper wire rated for 105ºC (221ºF) minimum.
NOTE: When using a time clock, the heater will display “Clock/ Fireman Sw” when the fireman’s switch
is open, indicating that the time clock has shut off the
call for heat.
FLAME ROLL-OUT SAFETY SWITCH
The heater is equipped with a thermal cutoff device to
revent flame roll-out in the event the heat exchanger
p
becomes blocked. This is a "single-use" type fusible
ink or thermal fuse, that must be replaced when dis-
l
abled by an over-temperature condition, caused by
excessive restriction in the heat exchanger flue passage.
HIGH LIMITS
The heater is equipped with two automatic high limits.
One is located in the inlet/outlet header, and the other
is located in the return header. Both are set to open at
135°F.
WATER FLOW SWITCH
The water flow switch ensures that the heater operates
only when the filter pump is in operation. It is located
on the outlet side of the In/Out header. It is factory
pre-wired and pre-set with a minimum water flow paddle. Install conduit to the upper jacket hole. Connect
two wires from the conduit to the appropriate terminal
wires behind the transformer cover (i.e. orange to
orange and orange/black to orange/black). No further
adjustment is needed.
NOTE: An erratic high limit is often characteristic of an
internal heat exchanger problem, e.g. scale build-up,
defective bypass. Refer to Troubleshooting section (on
page 36).
HIGH LIMIT REMOVAL
1. Shut off main electrical power switch to heater.
2. Remove inlet/outlet and/or return inspection
panel.
3. Remove defective high limit and replace with a
new high limit.
4. Replace inspection panel.
NOTE: The sheet metal cover should be in place at
all times to protect the flow switch from rain and other
environmental factors.
CAUTION: Do not operate the heater without the
function of a properly adjusted flow switch.

PILOT SAFETY
The heater employs a pilot safety which closes the
main gas valve within 8/10ths of a second whenever
the pilot flame is interrupted. The pilot flame is auto-
atically lit when the device is powered. The heater
m
performs its own safety check and opens the main
alve only after the pilot is proven to be lit.
v

burner hold-down bracket and spacer can become distorted from direct-flame impingement and this usually
necessitates replacement of these parts.
3. Lift burners from slotted spacers and slide from orifices. Clean with a wire brush.
4. Orifices usually do not need to be replaced. To
clean, run either copper wire or wood toothpick
through orifice. Do not enlarge hole. To remove
orifice, use a socket wrench and remove from
manifold. DO NOT overtighten when reinstalling.
PILOT REMOVAL AND CLEANING
1. Disconnect pilot tubing and wires from gas valve.
2. Remove pilot assembly from burner tray.

Clean out deposits over 1/16" in thickness.
1. Remove top and flue collector from cabinet.
2. Remove "V" baffles from heat exchanger.
3. Remove burner tray. (See page 33).
4. Remove heat exchanger from the heater and wash
with a garden hose, making sure soot is removed
from spaces between fins.
5. Reverse above procedure to reinstall.
NOTE: In extreme cases it may be necessary to do
steam cleaning at the local car wash. DO NOT WIRE
BRUSH.
COMBUSTION CHAMBER REMOVAL
To remove combustion chamber, you must first have
removed the heat exchanger.
Atmospheric Heaters
REFRACTORY PANELS - TOP VIEW
The heater may be cleaned from the return header
side, without breaking pipe connections. It is preferable, however, to remove both headers for better visibility through the tubes and to be sure the ground-up
lime dust does not get into the system.
Note that you do not remove the top panel or the
heater exchanger, generally.
After reaming, mount the wire brush in place of the
auger and clean out debris remaining in the tubes.
Another method is to remove the heat exchanger,
ream tubes and immerse heat exchanger in non-inhibited de-scale solvent for severe scale build-up.
DESOOTING PROCEDURE
WARNING: SOOT IS COMBUSTIBLE. EXERCISE
EXTREME CARE.
Soot will clog areas between fins and cause eventual
tube failure. Any sign of soot at the base of the burners or around the outer jacket indicates a need for
cleaning.
IMMERSION WELL REPLACEMENT
1. Shut off water to heater and drain heat exchanger.
2. Remove access panel on water connection side.
